     FIELD 
     The present innovations generally address apparatuses, methods, and systems for electronic commerce, and more particularly, include UNIVERSAL ELECTRONIC PAYMENT APPARATUSES, METHODS AND SYSTEMS (“UEP”). 
     BACKGROUND 
     Consumer transactions typically require a customer to select a product from a store shelf or website, and then to check the out at a checkout counter or webpage. Product information is selected from a webpage catalog or entered into a point-of-sale terminal, or the information is entered automatically by scanning an item barcode with an integrated barcode scanner at the point-of-sale terminal. The customer is usually provided with a number of payment options, such as cash, check, credit card or debit card. Once payment is made and approved, the point-of-sale terminal memorializes the transaction in the merchant&#39;s computer system, and a receipt is generated indicating the satisfactory consummation of the transaction.

     DETAILED DESCRIPTION 
     Universal Electronic Payment (UEP) 
     The UNIVERSAL ELECTRONIC PAYMENT APPARATUSES, METHODS AND SYSTEMS (hereinafter “UEP”) transform touchscreen inputs into a virtual wallet mobile application interface, via UEP components, into purchase transaction triggers and receipt notices.  FIG. 1  shows a block diagram illustrating example aspects of virtual mobile wallet purchasing in some embodiments of the UEP. In some implementations, the UEP may facilitate use of a virtual wallet, e.g.,  100 , for conducting purchase transactions. For example, a user  101  may utilize a mobile device  102  (e.g., smartphone, tablet computer, etc.) to conduct a purchase transaction for contents of a cart  103  (e.g., physical cart at a brick-and-mortar store, virtual cart at an online shopping site), optionally at a point-of-sale (PoS) client  104  (e.g., legacy terminal at a brick-and-mortar store, computing device at an online shopping site, another user with a virtual wallet application, for person-to-person funds transfers, etc.). The user may be able to choose from one or more cards to utilize for a transactions, the cards chosen from a virtual wallet of cards stored within a virtual mobile wallet application executing on the mobile device. Upon selecting one or more of the card options, the mobile device may communicate (e.g., via one/two-way near-field communication [NFC], Bluetooth, Wi-Fi, cellular connection, creating and capturing images of QR codes, etc.) the card selection information to the PoS terminal for conducting the purchase transaction. In some embodiments, the mobile device may obtain a purchase receipt upon completion of authorization of the transaction. Various additional features may be provided to the user via the virtual mobile wallet application executing on the mobile device, as described further below in the discussion with reference to at least  FIGS. 2-54 . 
       FIGS. 2A-B  shows user interface diagrams illustrating example aspects of a shopping mode of a virtual wallet application in some embodiments of the UEP. With reference to  FIG. 2A , in some embodiments, a user may utilize a virtual wallet application  201  to engage in purchase transactions. In various embodiments described herein, the virtual wallet application may provide numerous features to facilitate the user&#39;s shopping experience  202 . For example, the virtual wallet application may allow a user to perform broad searches for products  203 , as discussed further below in the discussion with reference to  FIG. 2B . 
     In some implementations, the virtual wallet application may provide a ‘discover shopping’ mode  211 . For example, the virtual wallet application executing on a user device may communicate with a server. The server may provide information to the virtual wallet on the consumer trends across a broad range of consumers in the aggregate. For example, the server may indicate what types of transactions consumers in the aggregate are engaging in, what they are buying, which reviews they pay attention to, and/or the like. In some implementations, the virtual wallet application may utilize such information to provide a graphical user interface to facilitate the user&#39;s navigation through such aggregate information, such as described in the discussion below with reference to  FIGS. 3A-C . For example, such generation of aggregate information may be facilitate by the UEP&#39;s use of centralized personal information platform components described below in the discussion with reference to  FIGS. 18-37 . 
     In some implementations, the virtual wallet application may allow the user to simultaneously maintain a plurality of shopping carts, e.g.,  212 - 213 . Such carts may, in some implementation, be purely virtual carts for an online website, but in alternate implementations, may reflect the contents of a physical cart in a merchant store. In some implementations, the virtual wallet application may allow the user to specify a current cart to which items the user desires will be placed in by default, unless the user specifies otherwise. In some implementations, the virtual wallet application may allow the user to change the current cart (e.g.,  213 ). In some implementations, the virtual wallet application may allow the user to create wishlists that may be published online or at social networks to spread to the user&#39;s friends. In some implementations, the virtual wallet application may allow the user to view, manage, and pay bills for the user,  214 . For example, the virtual wallet application may allow the user to import bills into the virtual wallet application interface by taking a snapshot of the bill, by entering information about the bill sufficient for the virtual wallet application to establish a communication with the merchant associated with the bill, etc. 
     In some implementations, the virtual wallet application may allow the user to shop within the inventories of merchants participating in the virtual wallet. For example, the inventories of the merchants may be provided within the virtual wallet application for the user to make purchases. In some implementations, the virtual wallet application may provide a virtual storefront for the user within the graphical user interface of the virtual wallet application. Thus, the user may be virtually injected into a store of the merchant participating in the UEP&#39;s virtual wallet application. 
     In some implementations, the virtual wallet application may utilize the location coordinates of the user device (e.g., via GPS, IP address, cellular tower triangulation, etc.) to identify merchants that are in the vicinity of the user&#39;s current location. In some implementations, the virtual wallet application may utilize such information to provide information to the user on the inventories of the merchants in the locality, and or may inject the merchant store virtually into the user&#39;s virtual wallet application. 
     In some implementations, the virtual wallet application may provide a shopping assistant  204 . For example, a user may walk into a physical store of a merchant. The user may require assistance in the shopping experience. In some implementations, the virtual wallet application may allow the user to turn on the shop assistant (see  217 ), and a store executive in the merchant store may be able to assist the user via another device. In some embodiments, a user may enter into a store (e.g., a physical brick-and-mortar store, virtual online store [via a computing device], etc.) to engage in a shopping experience. The user may have a user device. The user device  102  may have executing thereon a virtual wallet mobile app, including features such as those as described herein. Upon entering the store, the user device may communicate with a store management server. For example, the user device may communicate geographical location coordinates, user login information and/or like check-in information to check in automatically into the store. In some embodiments, the UEP may inject the user into a virtual wallet store upon check in. For example, the virtual wallet app executing on the user device may provide features as described below to augment the user&#39;s in-store shopping experience. In some embodiments, the store management server may inform a customer service representative (“CSR”) of the user&#39;s arrival into the store. For example, the CSR may have a CSR device, and an app (“CSR app”) may be executing thereon. For example, the app may include features such as described below in the discussion herein. The CSR app may inform the CSR of the user&#39;s entry, including providing information about the user&#39;s profile, such as the user&#39;s identity, user&#39;s prior and recent purchases, the user&#39;s spending patterns at the current and/or other merchants, and/or the like. In some embodiments, the store management server may have access to the user&#39;s prior purchasing behavior, the user&#39;s real-time in-store behavior (e.g., which items&#39; barcode did the user scan using the user device, how many times did the user scan the barcodes, did the user engage in comparison shopping by scanning barcodes of similar types of items, and/or the like), the user&#39;s spending patterns (e.g., resolved across time, merchants, stores, geographical locations, etc.), and/or like user profile information. The store management system may utilize this information to provide offers/coupons, recommendations and/or the like to the CSR and/or the user, via the CSR device and/or user device, respectively. In some embodiments, the CSR may assist the user in the shopping experience. For example, the CSR may convey offers, coupons, recommendations, price comparisons, and/or the like, and may perform actions on behalf of the user, such as adding/removing items to the user&#39;s physical/virtual cart, applying/removing coupons to the user&#39;s purchases, searching for offers, recommendations, providing store maps, or store 3D immersion views, and/or the like. In some embodiments, when the user is ready to checkout, the UEP may provide a checkout notification to the user&#39;s device and/or CSR device. The user may checkout using the user&#39;s virtual wallet app executing on the user device, or may utilize a communication mechanism (e.g., near field communication, card swipe, QR code scan, etc.) to provide payment information to the CSR device. Using the payment information, the UEP may initiate the purchase transaction(s) for the user, and provide an electronic receipt to the user device and/or CSR device. Using the electronic receipt, the user may exit the store with proof of purchase payment. 
     With reference to  FIG. 2B , in some implementations, the virtual wallet application  221  may provide a broad range of search results  222  in response to a user providing search keywords and/or filters for a search query. For example, the in the illustration of  FIG. 2B , a user searched for all items including “Acme” that were obtained by taking a snapshot of an item (as discussed further below in greater detail), and were dated in the year “2052” (see  223 ). In some implementations the search results may include historical transactions of the user  231 , offers ( 235 , for a new account, which the user can import into the virtual wallet application) and/or recommendations for the user based on the user&#39;s behavioral patterns, coupons  232 , bills  234 , discounts, person-2-person transfer requests  236 , etc., or offers based on merchant inventory availability, and/or the like. For example, the search results may be organized according to a type, date, description, or offers. In some implementations, the descriptions may include listings of previous prior (e.g., at the time of prior purchase), a current price at the same location where it was previously bought, and/or other offers related to the item (see, e.g.,  231 ). Some of the offerings may be stacked on top of each other, e.g., they may be applied to the same transaction. In some instances, such as, e.g., the payment of bills (see  234 ), the items may be paid for by an auto-pay system. In further implementations, the user may be have the ability to pay manually, or schedule payments, snooze a payment (e.g., have the payment alerts show up after a predetermined amount of time, with an additional interest charge provided to account for the delayed payment), and/or modify other settings (see  234 ). In some implementations, the user may add one or more of the items listed to a cart,  224 ,  237 . For example, the user may add the items to the default current cart, or may enter the name of an alternate (or new cart/wishlist) to add the items, and submit the command by activating a graphical user interface (“GUI”) element  237 . 
       FIGS. 3A-C  show user interface diagrams illustrating example aspects of a discovery shopping mode of a virtual wallet application in some embodiments of the UEP. In some embodiments, the virtual wallet application may provide a ‘discovery shopping’ mode for the user. For example, the virtual wallet application may obtain information on aggregate purchasing behavior of a sample of a population relevant to the user, and may provide statistical/aggregate information on the purchasing behavior for the user as a guide to facilitate the user&#39;s shopping. For example, with reference to  FIG. 3A , the discovery shopping mode  301  may provide a view of aggregate consumer behavior, divided based on product category (see  302 ). For example, the centralized personal information platform components described below in the discussion with reference to  FIGS. 18-37  may facilitate providing such data for the virtual wallet application. Thus, the virtual wallet application may provide visualization of the magnitude of consumer expenditure in particular market segment, and generate visual depictions representative of those magnitudes of consumer expenditure (see  303 - 306 ). In some embodiments, the virtual wallet application may also provide an indicator (see  309 ) of the relative expenditure of the user of the virtual wallet application (see blue bars); thus the user may be able to visualize the differences between the user&#39;s purchasing behavior and consumer behavior in the aggregate. The user may be able to turn off the user&#39;s purchasing behavior indicator (see  310 ). In some embodiments, the virtual wallet application may allow the user to zoom in to and out of the visualization, so that the user may obtain a view with the appropriate amount of granularity as per the user&#39;s desire (see  307 - 308 ). At any time, the user may be able to reset the visualization to a default perspective (see  311 ). 
     Similarly, the discovery shopping mode  321  may provide a view of aggregate consumer response to opinions of experts, divided based on opinions of experts aggregated form across the web (see  302 ). For example, the centralized personal information platform components described below in the discussion with reference to  FIGS. 18-37  may facilitate providing such data for the virtual wallet application. Thus, the virtual wallet application may provide visualizations of how well consumers tend to agree with various expert opinion on various product categories, and whose opinions matter to consumers in the aggregate (see  323 - 326 ). In some embodiments, the virtual wallet application may also provide an indicator (see  329 ) of the relative expenditure of the user of the virtual wallet application (see blue bars); thus the user may be able to visualize the differences between the user&#39;s purchasing behavior and consumer behavior in the aggregate. The user may be able to turn off the user&#39;s purchasing behavior indicator (see  330 ). In some embodiments, the virtual wallet application may allow the user to zoom in to and out of the visualization, so that the user may obtain a view with the appropriate amount of granularity as per the user&#39;s desire (see  327 - 328 ). At any time, the user may be able to reset the visualization to a default perspective (see  331 ). 
     With reference to  FIG. 3B , in some implementations, the virtual wallet application may allow users to create targeted shopping rules for purchasing (see  FIG. 3A, 312, 322 ). For example, the user may utilize the consumer aggregate behavior and the expert opinion data to craft rules on when to initiate purchases automatically. As an example, rule  341  specifies that the virtual wallet should sell the users iPad2 if its consumer reports rating falls below 3.75/5.0, before March 1, provided a sale price of $399 can be obtained. As another example, rule  342  specifies that the virtual wallet should buy an iPad3 if rule  341  succeeds before February 15. As another example, rule  343  specifies that the wallet should buy a Moto Droid Razr from the Android Market for less than $349.99 if its Slashdot rating is greater than 3.75 before February 1. Similarly, numerous rules with a wide variety of variations and dependencies may be generated for targeted shopping in the discovery mode. In some implementations, the virtual wallet user may allow the user to modify a rule. For example, the wallet may provide the user with an interface similar to  346  or  347 . The user may utilize tools available in the rule editor toolbox to design the rule according to the user&#39;s desires. In some implementations, the wallet may also provide a market status for the items that are subject to the targeted shopping rules. 
     With reference to  FIG. 3C , in some implementations, the virtual wallet application may provide a market watch feature, wherein the trends associated with items subject to targeted shopping rules may be tracked and visually represented for the user. For example, the visualization may take, in some implementations, the form of a ticker table, wherein against each item  351 (A)-(E) are listed a product category or cluster of expert opinions to which the product is related  352 , pricing indicators, including, but not limited to: price at the time of rule creation  352 , price at the time of viewing the market watch screen  353 , and a target price for the items (A)-(E). Based on the prices, the market watch screen may provide a trending symbol (e.g., up, down, no change, etc.) for each item that is subject to a targeted shopping rule. Where an item satisfied the targeted rule (see item (E)), the virtual wallet may automatically initiate a purchase transaction for that item once the target price is satisfied. 
       FIGS. 4A-B  show user interface diagrams illustrating example aspects of a shopping cart mode of a virtual wallet application in some embodiments of the UEP. With reference to  FIG. 4A , in some implementations, the virtual wallet application may be able to store, maintain and manage a plurality of shopping carts and/or wishlists ( 401 - 406 ) for a user. The carts may be purely virtual, or they may represent the contents of a physical cart in a merchant store. The user may activate any of the carts listed to view the items currently stored in a cart (e.g.,  410 - 416 ). In some implementations, the virtual wallet application may also provide wishlists, e.g., tech wishlist  417 , with items that the user desires to be gifted (see  418 - 419 ). In some implementations, the virtual wallet may allow the user to quickly change carts or wishlists from another cart or wishlist, using a pop-up menu, e.g.,  420 . 
     With reference to  FIG. 4B , in one implementation, the user may select a particular item to obtain a detailed view of the item,  421 . For example, the user may view the details of the items associated with the transaction and the amount(s) of each item, the merchant, etc.,  422 . In various implementations, the user may be able to perform additional operations in this view. For example, the user may (re)buy the item  423 , obtain third-party reviews of the item, and write reviews of the item  424 , add a photo to the item so as to organize information related to the item along with the item  425 , add the item to a group of related items (e.g., a household),  426 , provide ratings  427 , or view quick ratings from the user&#39;s friends or from the web at large. For example, such systems may be implemented using the example centralized personal information platform components described below in the discussion with reference to  FIGS. 18-37 . The user may add a photo to the transaction. In a further implementation, if the user previously shared the purchase via social channels, a post including the photo may be generated and sent to the social channels for publishing. In one implementation, any sharing may be optional, and the user, who did not share the purchase via social channels, may still share the photo through one or more social channels of his or her choice directly from the history mode of the wallet application. In another implementation, the user may add the transaction to a group such as company expense, home expense, travel expense or other categories set up by the user. Such grouping may facilitate year-end accounting of expenses, submission of work expense reports, submission for value added tax (VAT) refunds, personal expenses, and/or the like. In yet another implementation, the user may buy one or more items purchased in the transaction. The user may then execute a transaction without going to the merchant catalog or site to find the items. In a further implementation, the user may also cart one or more items in the transaction for later purchase. 
     The virtual wallet, in another embodiment, may offer facilities for obtaining and displaying ratings  427  of the items in the transaction. The source of the ratings may be the user, the user&#39;s friends (e.g., from social channels, contacts, etc.), reviews aggregated from the web, and/or the like. The user interface in some implementations may also allow the user to post messages to other users of social channels (e.g., TWITTER or FACEBOOK). For example, the display area  428  shows FACEBOOK message exchanges between two users. In one implementation, a user may share a link via a message  429 . Selection of such a message having embedded link to a product may allow the user to view a description of the product and/or purchase the product directly from the history mode. 
     In some implementations, the wallet application may display a shop trail for the user, e.g.,  430 . For example, a user may have reviewed a product at a number of websites (e.g., ElecReports, APPL FanBoys, Gizmo, Bing, Amazon, Visa Smartbuy feature (e.g., that checks various sources automatically for the best price available according to the user preferences, and provides the offer to the user), etc.), which may have led the user to a final merchant website where the user finally bought the product. In some implementations, the UEP may identify the websites that the user visited, that contributed to the user deciding to buy the product, and may reward them with a share of the revenues obtained by the “point-of-sale” website for having contributed to the user going to the point-of-sale website and purchasing the product there. For example, the websites may have agreements with product manufacturers, wholesalers, retail outlets, payment service providers, payment networks, amongst themselves, and/or the like with regard to product placement, advertising, user redirection and/or the like. Accordingly, the UEP may calculate a revenue share for each of the websites in the user&#39;s shopping trail using a revenue sharing model, and provide revenue sharing for the websites. 
     In some implementations, the virtual wallet may provide a SmartBuy targeted shopping feature. For example, the user may set a target price  431  for the product  422  that the user wishes to buy. The virtual wallet may provide a real-time market watch status update  432  for the product. When the market price available for the user falls below the user&#39;s target price  431 , the virtual wallet may automatically buy the product for the user, and provide a shipment/notification to the user. 
       FIG. 5  shows a user interface diagram illustrating example aspects of a bill payment mode of a virtual wallet application in some embodiments of the UEP. In some implementations, the virtual wallet application may provide a list of search results for bills  501 - 503  in response to a user activating element  214  in  FIG. 2A . In some implementations the search results may include historical billing transactions of the user, as well as upcoming bills (e.g.,  511 - 515 ). For example, the search results may be organized according to a type, date, description. In some implementations, the descriptions may include listings of previous prior (e.g., at the time of prior purchase), a current price at the same location where it was previously bought, and/or other offers related to the item (see, e.g.,  511 ). In some instances, such as, e.g., the payment of bills (see  514 ), the items may be paid for by an auto-pay system. In further implementations, the user may be have the ability to pay manually, or schedule payments, snooze a payment (e.g., have the payment alerts show up after a predetermined amount of time, with an additional interest charge provided to account for the delayed payment), and/or modify other settings (see  514 ). 
       FIGS. 6A-B  show user interface diagrams illustrating example aspects of a (local proximity) merchant shopping mode of a virtual wallet application in some embodiments of the UEP. In some implementations, upon activating elements  215  of  216  in  FIG. 2A , the virtual wallet application may presents screens  600  and  610 , respectively, as depicted in  FIG. 6A . In  FIG. 6, 600 , the virtual wallet application displays a list of merchants participating in the virtual wallet of the UEP, e.g.,  601 - 605 . Similarly, in  FIG. 6A, 610 , the virtual wallet application displays a list of merchants participating in the virtual wallet of the UEP and at or nearby the approximate location of the user the user. The user may click on any of the merchants listed in the two screens  600  and  610 , to be injected into the store inventory of the merchant. Upon injection, the user may be presented with a screen such as  620 , which is similar to the screen discussed above in the description with reference to  FIG. 4A  (center). Also, in some implementation, if a user clicks on any of the items listed on screen  620 , the user may be taken to a screen  630 , similar to the screen discussed above in the description with reference to FIG.  4 B. With reference to  FIG. 6B , in some embodiments, the user may be injected into a virtual reality 2D/3D storefront of the merchant. For example, the user may be presented with a plan map view of the store  641 . In some map views, the user may provided with the user&#39;s location (e.g., using GPS, or if not available, then using a coarse approximation using a cellular signal). In some implementations, the locations of the user&#39;s prior and current purchases may be provided for the user, if the user wishes (see  642 , the user can turn the indications off, in some implementations). In some implementations, the user may be provided with a 3D aisle view of an aisle within the virtual storefront. The user may point the view direction at any of the objects to obtain virtual tools to obtain items from off the “virtual shelf,” and place them in the user&#39;s virtual cart. The screen at  650  shows an augmented reality view of an aisle, where user may see pins of items suggested by a concierge, or that were bookmarked in their cart/wishlist highlighted through a live video view  65 X. In another view, a virtual store aisle view (e.g., akin to a Google map Street View) may be navigated  651  when the consumer is not at the store, but would like to look for product; the directional control  651  allows for navigation up and down the aisle, and rotation and views of items at the merchant location. Additionally, consumers may tap items in the shelves and create a new product pin, which may then be added 652 to a cart or wishlist for further transacting. 
       FIG. 7  shows user interface diagrams illustrating example aspects of allocating funds for a purchase payment within a virtual wallet application in some embodiments of the UEP. In one embodiment, the wallet mobile application may provide a user with a number of options for paying for a transaction via the wallet mode  701 . The wallet mode may facilitate a user to set preferences for a payment transaction, including settings funds sources  702 , payee  703 , transaction modes  704 , applying real-time offers to the transaction  705 , and publishing the transaction details socially  706 , as described in further detail below. 
     In one implementation, an example user interface  711  for making a payment is shown. The user interface may clearly identify the amount  712  and the currency  713  for the transaction. The amount may be the amount payable and the currency may include real currencies such as dollars and euros, as well as virtual currencies such as reward points. The user may select the funds tab  702  to select one or more forms of payment  717 , which may include various credit, debit, gift, rewards and/or prepaid cards. The user may also have the option of paying, wholly or in part, with reward points. For example, the graphical indicator  718  on the user interface shows the number of points available, the graphical indicator  719  shows the number of points to be used towards the amount due 234.56 and the equivalent  720  of the number of points in a selected currency (USD, for example). 
     In one implementation, the user may combine funds from multiple sources to pay for the transaction. The amount  715  displayed on the user interface may provide an indication of the amount of total funds covered so far by the selected forms of payment (e.g., Discover card and rewards points). The user may choose another form of payment or adjust the amount to be debited from one or more forms of payment until the amount  715  matches the amount payable  714 . Once the amounts to be debited from one or more forms of payment are finalized by the user, payment authorization may begin. 
     In one implementation, the user may select a secure authorization of the transaction by selecting the cloak button  722  to effectively cloak or anonymize some (e.g., pre-configured) or all identifying information such that when the user selects pay button  721 , the transaction authorization is conducted in a secure and anonymous manner. In another implementation, the user may select the pay button  721  which may use standard authorization techniques for transaction processing. In yet another implementation, when the user selects the social button  723 , a message regarding the transaction may be communicated to one of more social networks (set up by the user), which may post or announce the purchase transaction in a social forum such as a wall post or a tweet. In one implementation, the user may select a social payment processing option  723 . The indicator  724  may show the authorizing and sending social share data in progress. 
     In another implementation, a restricted payment mode  725  may be activated for certain purchase activities such as prescription purchases. The mode may be activated in accordance with rules defined by issuers, insurers, merchants, payment processor and/or other entities to facilitate processing of specialized goods and services. In this mode, the user may scroll down the list of forms of payments  726  under the funds tab to select specialized accounts such as a flexible spending account (FSA), health savings account (HAS)  727 , and/or the like and amounts to be debited to the selected accounts. In one implementation, such restricted payment mode  725  processing may disable social sharing of purchase information. 
     In one embodiment, the wallet mobile application may facilitate importing of funds via the import funds user interface  728 . For example, a user who is unemployed may obtain unemployment benefit fund  729  via the wallet mobile application. In one implementation, the entity providing the funds may also configure rules for using the fund as shown by the processing indicator message  730 . The wallet may read and apply the rules prior, and may reject any purchases with the unemployment funds that fail to meet the criteria set by the rules. Example criteria may include, for example, merchant category code (MCC), time of transaction, location of transaction, and/or the like. As an example, a transaction with a grocery merchant having MCC  5411  may be approved, while a transaction with a bar merchant having an MCC  5813  may be refused. 
       FIG. 8  shows user interface diagrams illustrating example aspects of selecting payees for funds transfers within a virtual wallet application in some embodiments of the UEP. In one embodiment, the payee screen  801  in the wallet mobile application user interface may facilitate user selection of one or more payees receiving the funds selected in the funds tab. In one implementation, the user interface may show a list of all payees  802  with whom the user has previously transacted or available to transact. The user may then select one or more payees,  803 . For example, a selection may include a multiple-merchant entry—this may be the case when a user is paying for products in a cart, wherein the products themselves are from multiple merchants. In another example, the user may be paying for the products placed in a plurality of cart, each cart including products from one or more merchants. The payees  803  may include larger merchants such as Amazon.com Inc., and individuals such as Jane P. Doe. Next to each payee name, a list of accepted payment modes for the payee may be displayed. In some implementations, the user may import  804  additional names into the address book included within the user interface  802 . 
     In one implementation, the user may select the payee Jane P. Doe  805  for receiving payment. Upon selection, the user interface may display additional identifying information  806  relating to the payee. The user interface may allow the user to contact the payee (e.g., call, text, email), modify the entry of the payee in the address book (e.g., edit, delete, merge with another contact), or make a payment to the payee  807 . For example, the user can enter an amount  808  to be paid to the payee. The user can include a note for the payee (or for the user herself) related to the payment,  809 . The user can also include strings attached to the payment. For example, the user can provide that the payment processing should occur only if the payee re-posts the user&#39;s note on a social networking site,  810 . The user can, at any time, modify the funding sources to utilize in the payment,  811 . Also, the user can utilize a number of different payment modes for each user,  812 . For example, additional modes such as those described in the discussion with reference to  FIG. 9B  may be used for the person-to-person payment. For example, a social payment mechanism may be employed for the person-to-person payment. Additional description on the social payment mechanism may be found in the discussion with reference to  FIGS. 40-47 and 49D . As another example, person-to-person payment may be made via a snap mobile mechanism, as described further below in the discussion with reference to  FIG. 12A . 
       FIGS. 9A-B  show user interface diagrams illustrating example additional aspects of the virtual wallet application in some embodiments of the UEP. With reference to  FIG. 9A , in some implementations, an offers screen  901  may provide real-time offers that are relevant to items in a user&#39;s cart for selection by the user. The user may select one or more offers (see  902 ) from the list of applicable offers  903  for redemption. In one implementation, some offers may be combined (see, e.g.,  904 ), while others may not (optionally). When the user selects an offer that may not be combined with another offer, the unselected offers may be disabled. In a further implementation, offers that are recommended by the wallet application&#39;s recommendation engine may be identified by an indicator, such as the one shown by  905 . An example offer recommendation engine is described further below in the discussion with reference to  FIG. 39 . In a further implementation, the user may read the details of the offer by expanding the offer row as shown by  905  in the user interface. The user may refresh offers displayed in the real-time offers screen at any time (see  906 ). 
     With reference to  FIG. 9B , in some implementations, the mode tab  911  may facilitate selection of a payment mode accepted by the payee. A number of payment modes may be available for selection. Example modes include, Bluetooth  912 , wireless  913 , snap mobile by user-obtained QR code  914 , secure chip  915 , TWITTER  916 , near-field communication (NFC)  921 , cellular  920 , snap mobile by user-provided QR code  919 , USB  918  and FACEBOOK  917 , among others. In one implementation, only the payment modes that are accepted by the payee may be selectable by the user. Other non-accepted payment modes may be disabled. 
     In one embodiment, the social tab  931  may facilitate integration of the wallet application with social channels  932 . In one implementation, a user may select one or more social channels  932  and may sign in to the selected social channel from the wallet application by providing to the wallet application the social channel user name and password  933  and signing in  934 . The user may then use the social button  935  to send or receive money through the integrated social channels. In a further implementation, the user may send social share data such as purchase information or links through integrated social channels. In another embodiment, the user supplied login credentials may allow UEP to engage in interception parsing. 
       FIGS. 10A-B  show user interface diagrams illustrating example aspects of a history mode of a virtual wallet application in some embodiments of the UEP. With reference to  FIG. 10A , in one embodiment, a user may select the history mode  1001  to view a history of prior purchases and perform various actions on those prior purchases. The wallet application may query the storage areas in the mobile device or elsewhere (e.g., one or more databases and/or tables remote from the mobile device) for prior transactions. The user interface may then display the results of the query such as transactions  1003 . The user interface may identify  1004 : a type of the transaction (e.g., previously shopped for items, bills that have been captured by camera in a snap mode, a person-to-person transfer [e.g., via social payment mechanism as described below in the discussion with reference to  FIGS. 40-47 ], etc.); the date of the transaction; a description of the transaction, including but not limited to: a cart name, cart contents indicator, total cost, merchant(s) involved in the transaction; a link to obtain a shoptrail (explained further below in greater detail), offers relating to the transaction, and any other relevant information. In some implementation, any displayed transaction, coupon, bill, etc. may be added to a cart for (re)purchase,  1005 . 
     In one embodiment, a user may select the history mode  1011  to view a history of filtered prior purchases and perform various actions on those prior purchases. For example, a user may enter a merchant identifying information such as name, product, MCC, and/or the like in the search bar  1012 . In another implementation, the user may use voice activated search feature to search the history. In another implementations, the wallet application may display a pop up screen  1016 , in which the user may enter advanced search filters, keywords, and/or the like. The wallet application may query the storage areas in the mobile device or elsewhere (e.g., one or more databases and/or tables remote from the mobile device) for transactions matching the search keywords. The user interface may then display the results of the query such as transactions  1003 . The user interface may identify  1014 : a type of the transaction (e.g., previously shopped for items, bills that have been captured by camera in a snap mode, a person-to-person transfer [e.g., via social payment mechanism as described below in the discussion with reference to  FIGS. 40-47 ], etc.); the date of the transaction; a description of the transaction, including but not limited to: a cart name, cart contents indicator, total cost, merchant(s) involved in the transaction; a link to obtain a shoptrail (explained further below in greater detail), offers relating to the transaction, and any other relevant information. In some implementation, any displayed transaction, coupon, bill, etc. may be added to a cart for (re)purchase,  1015 . 
     With reference to  FIG. 10B , in one embodiment, the history mode may also include facilities for exporting receipts. The export receipts pop up  1021  may provide a number of options for exporting the receipts of transactions in the history. For example, a user may use one or more of the options  1022 , which include save (to local mobile memory, to server, to a cloud account, and/or the like), print to a printer, fax, email, and/or the like. The user may utilize his or her address book to look up email or fax number for exporting. The user may also specify format options for exporting receipts. Example format options may include, without limitation, text files (.doc, .txt, .rtf, iif, etc.), spreadsheet (.csv, .xls, etc.), image files (.jpg, .tff, .png, etc.), portable document format (.pdf), postscript (.ps), and/or the like. The user may then click or tap the export button to initiate export of receipts. 
       FIGS. 11A-C  show user interface and logic flow diagrams illustrating example aspects of creating a user shopping trail within a virtual wallet application and associated revenue sharing scheme in some embodiments of the UEP. With reference to  FIG. 11A , in some implementations, a user may select the history mode  1101  to view a history of prior purchases and perform various actions on those prior purchases. The wallet application may query the storage areas in the mobile device or elsewhere (e.g., one or more databases and/or tables remote from the mobile device) for prior transactions. The user interface may then display the results of the query such as transactions  1103 . The user interface may identify  1104 : a type of the transaction (e.g., previously shopped for items, bills that have been captured by camera in a snap mode, a person-to-person transfer [e.g., via social payment mechanism as described below in the discussion with reference to  FIGS. 40-47 ], etc.); the date of the transaction; a description of the transaction, including but not limited to: a cart name, cart contents indicator, total cost, merchant(s) involved in the transaction; a link to obtain a shoptrail (explained further below in greater detail), offers relating to the transaction, and any other relevant information. In some implementation, any displayed transaction, coupon, bill, etc. may be added to a cart for (re)purchase,  1105 . 
     In one implementation, the user may select a transaction, for example transaction  1106 , to view the details of the transaction. For example, the user may view the details of the items associated with the transaction and the amount(s) of each item, the merchant, etc.,  1112 . In various implementations, the user may be able to perform additional operations in this view. For example, the user may (re)buy the item  1113 , obtain third-party reviews of the item, and write reviews of the item  1114 , add a photo to the item so as to organize information related to the item along with the item  1115 , add the item to a group of related items (e.g., a household), provide ratings  1117 , or view quick ratings from the user&#39;s friends or from the web at large. For example, such systems may be implemented using the example centralized personal information platform components described below in the discussion with reference to  FIGS. 18-37 . The user may add a photo to the transaction. In a further implementation, if the user previously shared the purchase via social channels, a post including the photo may be generated and sent to the social channels for publishing. In one implementation, any sharing may be optional, and the user, who did not share the purchase via social channels, may still share the photo through one or more social channels of his or her choice directly from the history mode of the wallet application. In another implementation, the user may add the transaction to a group such as company expense, home expense, travel expense or other categories set up by the user. Such grouping may facilitate year-end accounting of expenses, submission of work expense reports, submission for value added tax (VAT) refunds, personal expenses, and/or the like. In yet another implementation, the user may buy one or more items purchased in the transaction. The user may then execute a transaction without going to the merchant catalog or site to find the items. In a further implementation, the user may also cart one or more items in the transaction for later purchase. 
     The history mode, in another embodiment, may offer facilities for obtaining and displaying ratings  1117  of the items in the transaction. The source of the ratings may be the user, the user&#39;s friends (e.g., from social channels, contacts, etc.), reviews aggregated from the web, and/or the like. The user interface in some implementations may also allow the user to post messages to other users of social channels (e.g., TWITTER or FACEBOOK). For example, the display area  1118  shows FACEBOOK message exchanges between two users. In one implementation, a user may share a link via a message  1119 . Selection of such a message having embedded link to a product may allow the user to view a description of the product and/or purchase the product directly from the history mode. 
     In some implementations, the wallet application may display a shop trail for the user, e.g.,  1120 . For example, a user may have reviewed a product at a number of websites (e.g., ElecReports, APPL FanBoys, Gizmo, Bing, Amazon, Visa Smartbuy feature (e.g., that checks various sources automatically for the best price available according to the user preferences, and provides the offer to the user), etc.), which may have led the user to a final merchant website where the user finally bought the product. In some implementations, the UEP may identify the websites that the user visited, that contributed to the user deciding to buy the product, and may reward them with a share of the revenues obtained by the “point-of-sale” website for having contributed to the user going to the point-of-sale website and purchasing the product there. For example, the websites may have agreements with product manufacturers, wholesalers, retail outlets, payment service providers, payment networks, amongst themselves, and/or the like with regard to product placement, advertising, user redirection and/or the like. Accordingly, the UEP may calculate a revenue share for each of the websites in the user&#39;s shopping trail using a revenue sharing model, and provide revenue sharing for the websites. 
     In some implementations, the virtual wallet may provide a SmartBuy targeted shopping feature. For example, the user may set a target price  1121  for the product  1112  that the user wishes to buy. The virtual wallet may provide a real-time market watch status update  1122  for the product. When the market price available for the user falls below the user&#39;s target price  1121 , the virtual wallet may automatically buy the product for the user, and provide a shipment/notification to the user. 
       FIG. 11B  shows a logic flow diagram illustrating example aspects of generating a virtual wallet user shopping trail in some embodiments of the UEP, e.g., a User Shopping Trail Generation (“USTG”) component  1100 . In some implementations, a user device of a user, executing a virtual wallet application for the user, may track the shopping activities of a user for later retrieval and/or analysis. The device may obtain a user&#39;s input,  1101 , and determine a type of user input,  1102 . If the user engages in either browsing activity at a website of a merchant, or is navigating between websites (e.g., sometime when  1103 , option “No”), the device may track such activities. For example, the device may determine that the user&#39;s input is a navigational input ( 1104 , option “Yes”). The device may stop a timer associated with the current URL (e.g., of a merchant such as amazon.com, ebay.com, newegg.com, etc., or a review website such as shlashdot.org, cnet.com, etc.) that the user is located at, and determine a time count that the user spent at the URL,  1108 . The device may update a shop trail database (e.g., a local database, a cloud database, etc.) with the time count for the current URL,  1109 . The device may also identify a redirect URL to which the user will be navigating as a result of the user&#39;s navigation input,  1110 . The device may set the redict URL as the current URL, and reset activity and time counters for the current URL. The device may generate a new entry in the shop trail database for the URL that has been made current by the user&#39;s navigational input,  1111 . 
     If the user engaged in browsing activity at a current URL ( 1105 , option “Yes”), the device may identify the URL associated with the browsing activity (e.g., if the browsing can be performed on the device across multiple windows or tabs, etc.). The device may increment an activity counter to determine a level of user activity of the user at the URL where the browsing activity is occurring,  1106 . The device may update the shop trail database with the activity count for the URL,  1107 . 
     If the user desires to engage in a purchase transaction, e.g., after visiting a number of URLs about the product (e.g., after reading reviews about a product at a number of consumer report websites, the user navigates to amazon.com to buy the product), see  1103 , option “Yes,” the device may set the current URL as the “point-of-sale” URL (e.g., the merchant at which the user finally bought the product—e.g., amazon.com),  1112 . The device may stop the time for the current URL, and update the shop trail database for the current URL,  1113 . The device may generate a card authorization request to initiate the purchase transaction,  1114 , and provide the card authorization request for transaction processing (see, e.g., PTA  5700  component described below in the discussion with reference to  FIG. 57A-B ). 
     In some implementations, the device may also invoke a revenue sharing component, such as the example STRS  1120  component described below in the discussion with reference to  FIG. 11C . 
       FIG. 11C  shows a logic flow diagram illustrating example aspects of implementing a user shopping trail-based revenue sharing model in some embodiments of the UEP, e.g., a Shopping Trail Revenue Sharing (“STRS”) component  1120 . In some implementations, a user may have reviewed a product at a number of websites, which may have led the user to a final merchant website where the user finally bought the product. In some implementations, the UEP may identify the websites that the user visited, that contributed to the user deciding to buy the product, and may reward them with a share of the revenues obtained by the “point-of-sale” website for having contributed to the user going to the point-of-sale website and purchasing the product there. For example, the websites may have agreements with product manufacturers, wholesalers, retail outlets, payment service providers, payment networks, amongst themselves, and/or the like with regard to product placement, advertising, user redirection and/or the like. For example, a server may have stored a table of revenue sharing ratios, that provides a predetermined revenue sharing scheme according to which contributing websites will receive revenue for the user&#39;s purchase. 
     Accordingly, in some implementations, a server may obtain a list of URLs included in a user&#39;s shopping trail, and their associated activity and time counts,  1121 . The server may identify a point-of-sale URL where the user made the purchase for which revenue is being shared among the URLs in the shopping trail,  1122 . The server may calculate a total activity count, and a total time count, by summing up activity and time counts, respectively, of all the URLs in the user&#39;s shopping trail,  1123 . The server may calculate activity and time ratios of each of the URLs,  1124 . The server may obtain a revenue sharing model (e.g., a database table/matrix of weighting values) for converting activity and time ratios for each URL into a revenue ratio for that URL,  1125 . The server may calculate a revenue share,  1126 , for each of the URLs in the user&#39;s shopping trail using the revenue sharing model and the revenue ratios calculated for each URL. The server may provide a notification of the revenue for each URL (e.g., to each of the URLs and/or the point-of-sale URL from whom revenue will be obtained to pay the revenue shares of the other URLs in the user&#39;s shopping trail),  1127 . In some implementations, the server may generate card authorization requests and/or batch clearance requests for each of the revenue payments due to the URLs in the user&#39;s shopping trail, to process those transactions for revenue sharing. 
       FIGS. 12A-H  show user interface and logic flow diagrams illustrating example aspects of a snap mode of a virtual wallet application in some embodiments of the UEP. With reference to  FIG. 12A , in some implementations, a user may select the snap mode  1201  to access its snap features. The snap mode may handle any machine-readable representation of data. Examples of such data may include linear and 2D bar codes such as UPC code and QR codes. These codes may be found on receipts  1206 , product packaging  1202 , coupons  1203 , payment notes  1204 , invoices  1205 , credit cards and/or other payment account plastic cards or equivalent  1207 , and/or the like. The snap mode may process and handle pictures of receipts, products, offers, credit cards or other payment devices, and/or the like. An example user interface  1211  in snap mode is shown in  FIG. 12A . A user may use his or her mobile phone to take a picture of a QR code  1215  and/or a barcode  1214 . In one implementation, the bar  1216  and snap frame  1213  may assist the user in snapping codes properly. For example, the snap frame  1213 , as shown, does not capture the entirety of the code  1214 . As such, the code captured in this view may not be resolvable as information in the code may be incomplete. When the code  1215  is completely framed by the snap frame  5215 , the device may automatically snap a picture of the code,  1219 . Upon finding the code, in one implementation, the user may initiate code capture using the mobile device camera,  1212 . In some implementations, the user may adjust the zoom level of the camera to assist in capturing the code,  1217 . In some implementations, the user may add a GPS tag to the captured code,  1218 . 
     With reference to  FIG. 12B , in some implementations, where the user has not yet interacted with an item, the user may view details of the item designed to facilitate the user to purchase the item at the best possible terms for the user. For example, the virtual wallet application may provide a detailed view of the item at the point where it was snapped by the user using the user device,  1221 , including an item description, price, merchant name, etc. The view may also provide a QR code  1222 , which the user may tap to save to the wallet for later use, or to show to other users who may snap the QR code to purchase the item. In some implementations, the view may provide additional services for the user, including but not limited to: concierge service; shipment services, helpline, and/or the like,  1223 . In some implementations, the view may provide prices from competing merchants locally or on the web,  1224 . Such pricing data may be facilitated by the centralized personal information platform components described further below in the discussion with reference to  FIGS. 18-37 . In some implementations, the view may provide the user with the option to (see  1225 ): store the snapped code for later, start over and generate a new code, turn on or off a GPS tagging feature, use a previously snapped QR code, enter keywords associated with the QR code, associated the items related to the QR code to an object, and/or the like. In some implementations, the virtual wallet may provide a SmartBuy targeted shopping feature. For example, the user may set a target price  1226  for the product  1221  that the user wishes to buy. The virtual wallet may provide a real-time market watch status update  1227  for the product. When the market price available for the user falls below the user&#39;s target price  1226 , the virtual wallet may automatically buy the product for the user, and provide a shipment/notification to the user. The user may at any time add the item to one of the user&#39;s carts or wishlists (see  1228 ). 
     In one implementation, in particular when the user has previously interacted with the item that is snapped, the user may view the details of the items  1232  and the amount(s) of each item, the merchant, etc.,  1232 . In various implementations, the user may be able to perform additional operations in this view. For example, the user may (re)buy the item  1233 , obtain third-party reviews of the item, and write reviews of the item  1234 , add a photo to the item so as to organize information related to the item along with the item  1235 , add the item to a group of related items (e.g., a household), provide ratings  1237 , or view quick ratings from the user&#39;s friends or from the web at large. For example, such systems may be implemented using the example centralized personal information platform components described below in the discussion with reference to  FIGS. 18-37 . The user may add a photo to the transaction. In a further implementation, if the user previously shared the purchase via social channels, a post including the photo may be generated and sent to the social channels for publishing. In one implementation, any sharing may be optional, and the user, who did not share the purchase via social channels, may still share the photo through one or more social channels of his or her choice directly from the history mode of the wallet application. In another implementation, the user may add the transaction to a group such as company expense, home expense, travel expense or other categories set up by the user. Such grouping may facilitate year-end accounting of expenses, submission of work expense reports, submission for value added tax (VAT) refunds, personal expenses, and/or the like. In yet another implementation, the user may buy one or more items purchased in the transaction. The user may then execute a transaction without going to the merchant catalog or site to find the items. In a further implementation, the user may also cart one or more items in the transaction for later purchase. 
     The history mode, in another embodiment, may offer facilities for obtaining and displaying ratings  1237  of the items in the transaction. The source of the ratings may be the user, the user&#39;s friends (e.g., from social channels, contacts, etc.), reviews aggregated from the web, and/or the like. The user interface in some implementations may also allow the user to post messages to other users of social channels (e.g., TWITTER or FACEBOOK). For example, the display area  1238  shows FACEBOOK message exchanges between two users. In one implementation, a user may share a link via a message  1239 . Selection of such a message having embedded link to a product may allow the user to view a description of the product and/or purchase the product directly from the history mode. 
     In some implementations, the wallet application may display a shop trail for the user, e.g.,  1240 . For example, a user may have reviewed a product at a number of websites (e.g., ElecReports, APPL FanBoys, Gizmo, Bing, Amazon, Visa Smartbuy feature (e.g., that checks various sources automatically for the best price available according to the user preferences, and provides the offer to the user), etc.), which may have led the user to a final merchant website where the user finally bought the product. In some implementations, the UEP may identify the websites that the user visited, that contributed to the user deciding to buy the product, and may reward them with a share of the revenues obtained by the “point-of-sale” website for having contributed to the user going to the point-of-sale website and purchasing the product there. For example, the websites may have agreements with product manufacturers, wholesalers, retail outlets, payment service providers, payment networks, amongst themselves, and/or the like with regard to product placement, advertising, user redirection and/or the like. Accordingly, the UEP may calculate a revenue share for each of the websites in the user&#39;s shopping trail using a revenue sharing model, and provide revenue sharing for the websites. 
     In some implementations, the virtual wallet may provide a SmartBuy targeted shopping feature. For example, the user may set a target price  1241  for the product  1232  that the user wishes to buy. The virtual wallet may provide a real-time market watch status update  1242  for the product. When the market price available for the user falls below the user&#39;s target price  1241 , the virtual wallet may automatically buy the product for the user, and provide a shipment/notification to the user. 
     With reference to  FIGS. 12C-D , in one embodiment, the snap mode may facilitate payment reallocation for a previously completed transaction ( FIG. 12C ), or a transaction to performed at present ( FIG. 12D ). For example, a user may buy grocery and prescription items from a retailer Acme Supermarket. The user may, inadvertently or for ease of checkout for example, have already used his or her traditional payment card to pay for both grocery and prescription items, and obtained a receipt. However, the user may have an FSA account that could have been used to pay for prescription items, and which would have provided the user a better price or other economic benefits. In such a situation, the user may use the snap mode to initiate transaction reallocation. 
     As shown, the user may snap  1251 ,  1261  a picture of a barcode on an receipt  1253 ,  1263 , upon which the virtual wallet application may present the receipt data  1252 ,  1262  using information from the pay code. The user may now reallocate expenses to their optimum accounts  1254 ,  1264 . In some implementations, the user may also dispute the transaction  1255 ,  1265  or archive the receipt  1256 ,  1266 . 
     In one implementation, when the reallocate button is selected, the wallet application may perform optical character recognition (OCR) of the receipt. Each of the items in the receipt may then be examined to identify one or more items which could be charged to which payment device or account for tax or other benefits such as cash back, reward points, etc. In this example, there is a tax benefit if the prescription medication charged to the user&#39;s Visa card is charged to the user&#39;s FSA. The wallet application may then perform the reallocation as the back end. The reallocation process may include the wallet contacting the payment processor to credit the amount of the prescription medication to the Visa card and debit the same amount to the user&#39;s FSA account. In an alternate implementation, the payment processor (e.g., Visa or MasterCard) may obtain and OCR the receipt, identify items and payment accounts for reallocation and perform the reallocation. In one implementation, the wallet application may request the user to confirm reallocation of charges for the selected items to another payment account. The receipt may be generated after the completion of the reallocation process. As discussed, the receipt shows that some charges have been moved from the Visa account to the FSA. 
     With reference to  FIG. 12E , in one embodiment, the snap mode may also facilitate offer identification, application and storage for future use. For example, in one implementation, a user may snap an account code, an offer code  1271  (e.g., a bar code, a QR code, and/or the like). The wallet application may then generate an account card text, coupon text, offer text  1272  from the information encoded in the offer code. The user may perform a number of actions on the offer code. For example, the user may use the reallocate button  1273  to reallocate prior purchases that would have been better made using the imported card, coupon, offer, etc., and the virtual wallet application may provide a notification of reallocation upon modifying the accounts charged for the previous transactions of the user. 
     In one embodiment, the snap mode may also offer facilities for adding a funding source to the wallet application. In one implementation, a pay card such as a credit card, debit card, pre-paid card, smart card and other pay accounts may have an associated code such as a bar code or QR code. Such a code may have encoded therein pay card information including, but not limited to, name, address, pay card type, pay card account details, balance amount, spending limit, rewards balance, and/or the like. In one implementation, the code may be found on a face of the physical pay card. In another implementation, the code may be obtained by accessing an associated online account or another secure location. In yet another implementation, the code may be printed on a letter accompanying the pay card. A user, in one implementation, may snap a picture of the code. The wallet application may identify the pay card and may display the textual information encoded in the pay card. The user may then perform verification of the information by selecting a verify button. In one implementation, the verification may include contacting the issuer of the pay card for confirmation of the decoded information and any other relevant information. In one implementation, the user may add the pay card to the wallet by selecting a ‘add to wallet’ button. The instruction to add the pay card to the wallet may cause the pay card to appear as one of the forms of payment under the funds tab discussed above. 
     With reference to  FIG. 12F , in some implementations, a user may be advantageously able to provide user settings into a device producing a QR code for a purchase transaction, and then capture the QR code using the user&#39;s mobile device. For example, a display device of a point-of-sale terminal may be displaying a checkout screen, such as a web browser executing on a client, e.g.,  1281 , displaying a checkout webpage of an online shopping website, e.g.,  1282 . In some implementations, the checkout screen may provide a user interface element, e.g.,  1283   a - b , whereby the user can indicate the desire to utilize snap mobile payment. For example, if the user activates element  1281   a , the website may generate a QR code using default settings of the user, and display the QR code, e.g.,  1285 , on the screen of the client for the user to capture using the user&#39;s mobile device. In some implementations, the user may be able to activate a user interface element, e.g.,  1283   b , whereby the client may display a pop-up menu, e.g.,  1284 , with additional options that the user may select from. In some implementations, the website may modify the QR code  1285  in real-time as the user modifies settings provided by activating the user interface element  1283   b . Once the user has modified the settings using the pop-up menu, the user may capture a snapshot of the QR code to initiate purchase transaction processing. 
       FIG. 12G  shows a logic flow diagram illustrating example aspects of executing a snap mobile payment in some embodiments of the UEP, e.g., a Snap Mobile Payment Execution (“SMPE”) component  1200 . In some implementations, a user may desire to purchase a product, service, offering, and/or the like (“product”), from a merchant via a merchant online site or in the merchant&#39;s store. The user may communicate with a merchant server via a client. For example, the user may provide user input, e.g.,  1201 , into the client indicating the user&#39;s desire to checkout shopping items in a (virtual) shopping cart. The client may generate a checkout request, e.g.,  1202 , and provide the checkout request to the merchant server. The merchant server may obtain the checkout request from the client, and extract the checkout detail (e.g., XML data) from the checkout request, e.g.,  1203 . For example, the merchant server may utilize a parser such as the example parsers described below in the discussion with reference to  FIG. 61 . The merchant server may extract the product data, as well as the client data from the checkout request. In some implementations, the merchant server may query, e.g.,  1204 , a merchant database to obtain product data, e.g.,  1205 , such as product pricing, sales tax, offers, discounts, rewards, and/or other information to process the purchase transaction. 
     In response to obtaining the product data, the merchant server may generate, e.g.,  1206 , a QR pay code, and/or secure display element according to the security settings of the user. For example, the merchant server may generate a QR code embodying the product information, as well as merchant information required by a payment network to process the purchase transaction. For example, the merchant server may first generate in real-time, a custom, user-specific merchant-product XML data structure having a time-limited validity period, such as the example ‘QR data’ XML data structure provided below: 
     
       
         
           
               
             
               
                   
               
             
            
               
                 &lt;QR_data&gt;

     In some implementations, the merchant may generate QR code using the XML data. For example, the merchant server may utilize the PHP QR Code open-source (LGPL) library for generating QR Code, 2-dimensional barcode, available at http://phpqrcode.sourceforge.net/. For example, the merchant server may issue PHP commands similar to the example commands provided below: 
     
       
         
           
               
               
             
               
                   
                   
               
             
            
               
                   
                 &lt;?PHP 
               
               
                   
                 header(‘Content-Type: text/plain’); 
               
               
                   
                 // Create QR code image using data stored in $data variable 
               
               
                   
                 QRcode::png($data, ‘qrcodeimg.png’); 
               
               
                   
                 ?&gt; 
               
               
                   
                   
               
            
           
         
       
     
     The merchant server may provide the QR pay code to the client, e.g.,  1206 . The client may obtain the QR pay code, and display the QR code, e.g.,  1207  on a display screen associated with the client device. In some implementations, the user may utilize a user device, e.g.,  1209 , to capture the QR code presented by the client device for payment processing. The client device may decode the QR code to extract the information embedded in the QR code. For example, the client device may utilize an application such as the ZXing multi-format 1D/2D barcode image processing library, available at http://code.google.com/p/zxing/ to extract the information from the QR code. In some implementations, the user may provide payment input into the user device, e.g.,  1208 . Upon obtaining the user purchase input, the user device may generate a card authorization request, e.g.,  1209 , and provide the card authorization request to a pay network server (see, e.g.,  FIG. 57A ). 
       FIGS. 12H-I  show logic flow diagrams illustrating example aspects of processing a Quick Response code in some embodiments of the UEP, e.g., a Quick Response Code Processing (“QRCP”) component  1210 . With reference to  FIG. 12H , in some implementations, a virtual wallet application executing on a user device may determine whether a QR code has been captured in an image frame obtained by a camera operatively connected to the user device, and may also determine the type, contents of the QR code. Using such information, the virtual wallet application may redirect the user experience of the user and/or initiating purchases, update aspects of the virtual wallet application, etc. For example, the virtual wallet application may trigger the capture of an image frame by a camera operatively connected to the user device,  1211 . The virtual wallet application may utilize an image segmentation algorithm to identify a foreground in the image,  1212 , and may crop the rest of the image to reduce background noise in the image,  1213 . The virtual wallet application may determine whether the foreground image includes a QR code from which data can be reliably read (e.g., this may not be so if the image does not include a QR code, or the QR code is partially cropped, blurred, etc.),  1214 . For example, the virtual wallet application may utilize a code library such as the ZXing multi-format 1D/2D barcode image processing library, available at http://code.google.com/p/zxing/ to try and extract the information from the QR code. If the virtual wallet application is able to detect a QR code ( 1215 , option “Yes”), the virtual wallet application may decode the QR code, and extract data from the QR code,  1217 . If the virtual wallet application is unable to detect a QR code ( 1215 , option “No”), the virtual wallet application may attempt to perform Optical Character Recognition on the image. For example, the virtual wallet application may utilize the Tesseract C++ open source OCR engine, available at www.pixel-technology.com/freewarw/tessnet2, to perform the optical character recognition,  1216 . Thus, the virtual wallet application may obtain the data encoded into the image, and may continue if the data can be processed by the virtual wallet application. The virtual wallet application may query a database using fields identified in the extracted data, for a type of the QR code,  1218 . For example, the QR code could include an invoice/bill, a coupon, a money order (e.g., in a P2P transfer), a new account information packet, product information, purchase commands, URL navigation instructions, browser automation scripts, combinations thereof, and/or the like. 
     In some embodiments, the QR code may include data on a new account to be added to the virtual wallet application (see  1219 ). The virtual wallet application may query an issuer of the new account (as obtained from the extracted data), for the data associated with the new account,  1220 . The virtual wallet application may compare the issuer-provided data to the data extracted from the QR code,  611 . If the new account is validated ( 1221 , option “Yes”), the virtual wallet application may update the wallet credentials with the details of the new account,  1223 , and update the snap history of the virtual wallet application using the data from the QR code,  1224 . 
     With reference to  FIG. 12I , in some embodiments, the QR code may include data on a bill, invoice, or coupon for a purchase using the virtual wallet application (see  1225 ). The virtual wallet application may query merchant(s) associated with the purchase (as obtained from the extracted data), for the data associated with the bill, invoice, or coupon for a purchase (e.g., offer details, offer ID, expiry time, etc.),  1226 . The virtual wallet application may compare the merchant-provided data to the data extracted from the QR code,  1227 . If the bill, invoice, or coupon for a purchase is validated ( 1228 , option “Yes”), the virtual wallet application may generate a data structure (see e.g., XML QR data structure in description above with reference to  FIG. 12F ) including the QR-encoded data for generating and providing a card authorization request,  1229 , and update the snap history of the virtual wallet application using the data from the QR code,  1230 . 
     In some embodiments, the QR code may include product information, commands, user navigation instructions, etc. for the virtual wallet application (see  1231 ). The virtual wallet application may query a product database using the information encoded in the QR. The virtual wallet application may provide various features including, without limitation, displaying product information, redirecting the user to: a product page, a merchant website, a product page on a merchant website, add item(s) to a user shopping cart at a merchant website, etc. In some implementations, the virtual wallet application may perform a procedure such as described above for any image frame pending to be processed, and/or selected for processing by the user (e.g., from the snap history). 
       FIGS. 13A-B  show user interface and logic flow diagrams illustrating example aspects of an offers mode of a virtual wallet application in some embodiments of the UEP. With reference to  FIG. 13A , in some implementations, a user may desire to obtain new offers in the user&#39;s virtual wallet application, or may desire to exchange an existing offer for a new one (or a plurality of offers) (e.g., offers  1301  may be replaced at the user&#39;s command). For example, the user may provide an input indicating a desire to replace offer  1302 . In response, the virtual wallet application may provide a set of replacement offers  1303 , from which the user may choose one or more offers to replace the offer  1302 . 
       FIG. 13B  shows a logic flow diagram illustrating example aspects of generating and exchanging offer recommendations in some embodiments of the UEP, e.g., an Offer Recommendation and Exchange (“ORE”) component  1310 . In some implementations, a user may desire to obtain new offers in the user&#39;s virtual wallet application, or may desire to exchange an existing offer for a new one (or a plurality of offers). The user may provide an input for display of such offers,  1301 . The user&#39;s device may obtain the user&#39;s input, and determine whether the user desires to obtain a new offer, or obtain offers in exchange for an offer currently stored within the user&#39;s virtual wallet application executing on the device,  1302 . If the device determines that the user desires to exchange a pre-existing offer, e.g.,  1303 , option “Yes,” the device may extract details of the offer that the user desires to exchange. For example, the device may correlate the position of the user&#39;s touchscreen input (e.g., where the device has a touchscreen interface) to an offer displayed on the screen. The device may also determine that the user utilized a gesture associated with the offer displayed on the screen that indicates the user&#39;s desire to exchange the offer with which the user gesture is associated. The device may query its database for an offer corresponding to the displayed offer, and may extract the details of the offer,  1304 , by parsing the database-returned offer using a parser, such as the example parsers described below in the discussion with reference to  FIG. 61 . In some implementations, the device may extract any user-input offer generation restrictions (e.g., such as types of filters the user may have applied to offers the user desires, keywords related to the kinds of offers the user may desire, etc.) provided by the user as input,  1305 . The device may generate an offer generation/exchange request for a pay network server using the extracted data on the offer to be exchanged (if any), and the user preferences for types of offers desired (if any), e.g., as a HTTP(S) POST request similar to the examples provided in the discussions below. 
     In some implementations, the pay network server may parse the offer generation/exchange request,  1307 , using parsers such as the example parser described below in the discussion with reference to  FIG. 61 . The pay network server may generate a user behavior data query,  1308 . For example, the server may utilize PHP/SQL commands to query a relational pay network database for user prior behavior data. For example, the pay network server may obtain such data generated using centralized personal information platform components, such as those described in the discussion below with reference to  FIGS. 18-37 , as well as a user behavior analysis component, such as the example UBA component described below in the discussion with reference to  FIG. 38 . The database may provide such user behavior data and analysis thereof to the pay network server,  1309 . Using the prior user behavior data and/or analysis thereof, and using the details of the exchanged offer and/or user offer generation restrictions, the pay network server may generate offers to provide for the user. For example, the pay network server may utilize a user behavior-based offer recommendation component such as the example UBOR component described in the discussion below with reference to  FIG. 39 . The server may provide the generated offers to the device, which may display the received offers to the user,  1311 . In some implementations, the user may provide an input indicating a desire to redeem one of the offers provided by the pay network server,  1312 . In response, the device may generate a card authorization request incorporating the details of the offer chosen for redemption by the user,  1313 , and provide the generated card authorization request for purchase transaction processing (e.g., as an input to the example PTA component described below in the discussion with reference to  FIGS. 57A-B ). 
       FIG. 14  shows user interface diagrams illustrating example aspects of a general settings mode of a virtual wallet application in some embodiments of the UEP. In some implementations, the virtual wallet application may provide a user interface where the user can modify the settings of the wallet,  1401 . For example, the user may modify settings such as, but not limited to: general settings  1411  (e.g., user information, wallet information, account information within the wallet, devices linked to the wallet, etc.); privacy controls  1412  (e.g., controlling information that is provided to merchants, payment networks, third-parties, etc.); purchase controls  1413  (e.g., placing specific spending restrictions, or proscribing particular type of transaction); notifications  1414 ; wallet bonds  1415  (e.g., relationship made with other virtual wallets, such that information, settings, (parental) controls, and/or funds may flow between the wallets seamlessly);  1416  social payment settings (see, e.g.,  FIGS. 40-47 ); psychic wishlists  1417  (e.g., controlling the type of user behaviors to consider in generating offers, recommendations—see, e.g.,  FIG. 39 ); targeted shopping  1418  (e.g., setting target prices at which buying of products is automatically triggered—see, e.g.,  FIGS. 11A, 12B -C); or post purchase settings  1419  (e.g., settings regarding refunds, returns, receipts, reallocation of expenses (e.g., to FSA or HAS accounts), price matching (e.g., if the price of the purchased item falls after the user buys it), etc. 
     In a category of general settings ( 1411 ), a user may be able to modify settings such as, but not limited to: user information  1421 , user device  1422 , user accounts  1423 , shopping sessions  1424 , merchants that are preferred  1425 , preferred products and brand names, preferred modes (e.g., settings regarding use of NFC, Bluetooth, and/or the like), etc. 
       FIG. 15  shows a user interface diagram illustrating example aspects of a wallet bonds settings mode of a virtual wallet application in some embodiments of the UEP. In a category of wallet bonds settings (see  FIG. 14, 1415 ), a user may be able to modify settings such as, but not limited to, settings regarding: parent wallets  1501  (e.g., those that have authorization to place restriction on the user&#39;s wallet); child wallets  1502  (e.g., those wallets over which the user has authorization to place restrictions); peer wallets  1503  (e.g., those wallets that have a similar level of control and transparency); ad hoc wallets  1504  (e.g., those wallets that are connected temporarily in real-time, for example, for a one-time funds transfer); partial bond wallets (e.g., such as bonds between corporate employer virtual wallet and an employee&#39;s personal wallet, such that an employer wallet may provide limited funds with strings attached for the employee wallet to utilize for business purposes only), and/or the like. 
       FIGS. 16A-C  show user interface diagrams illustrating example aspects of a purchase controls settings mode of a virtual wallet application in some embodiments of the UEP. With reference to  FIG. 16A , in some implementations, a user may be able to view and/or modify purchase controls that allow only transaction that satisfy the purchase controls to be initiated from the wallet. In one implementation, a consumer may configure consumer-controlled fraud prevention parameters to restrict a purchase transaction via his electronic wallet, e.g., transaction time, maximum amount, type, number of transactions per day, and/or the like. For example, a consumer may enroll with an electronic wallet service (e.g., Visa V-Wallet) by creating an e-wallet account and adding a payment account to the e-wallet (e.g., a credit card, a debit card, a PayPal account, etc.). The consumer may configure parameters to restrict the wallet transactions. For example, the consumer may configure a maximum one-time transaction amount (e.g., $500.00, etc.). For another example, the consumer may specify a time range of transactions to be questionable (e.g., all transactions occurring between 2 am-6 am, etc.). For another example, the consumer may specify the maximum number of transactions per day (e.g., 20 per day, etc.). For further examples, the consumer may specify names and/or IDs of merchants with whom the transactions may be questionable (e.g., Internet spam sites, etc.). 
     In one implementation, the consumer may configure the purchase control settings to detect and block all susceptible transactions. For example, when an attempted transaction of an amount that exceeds the maximum specified transaction amount occurs, the electronic wallet may be configured to reject the transaction and send an alert to the consumer. The transaction may be resumed once the consumer approves the transaction. In another implementation, if the UEP does not receive confirmation from the consumer to resume a susceptible transaction, the UEP may send a notification to the merchant to cancel the transaction. In one implementation, the consumer may configure the time period of clearance (e.g., 12 hours, etc.). In another implementation, UEP may determine a default maximum clearance period in compliance with regulatory requirements (e.g., 24 hours after soft posting, etc.). 
     In one implementation, the UEP may provide the consumer with a universal payment platform, wherein a user may associated one or more payment accounts with a universal payment platform and pay with the universal payment platform. Within embodiments, the consumer may create an electronic wallet service account and enroll with the electronic wallet (e.g., Visa V-Wallet, etc.) via UEP. In alternative embodiments, a consumer may associate a consumer bank account with an existing electronic wallet. For example, a consumer may provide payment information, such as bank account number, bank routing number, user profile information, to an electronic wallet management consumer onboarding user interface, to associate an account with the electronic wallet. In another implementation, a consumer may enroll with the electronic wallet during online checkout. For example, a merchant site may provide an electronic wallet button at the checkout page (e.g., a Visa V-Wallet logo, etc.), and upon consumer selection of the electronic wallet button, the consumer may be prompted to enter bank account information (e.g., card number, etc.) to register a payment card (e.g., a credit card, a debit card, etc.) with the electronic wallet via a pop-up window. 
     In one implementation, upon receiving consumer enrollment bank account data, the UEP may generate an enrollment request to the electronic wallet platform (e.g., Visa V-Wallet payment network, etc.). In one implementation, an exemplary consumer enrollment data request in eXtensible Markup Language (XML). In further implementations, the consumer may be issued a UEP electronic wallet device upon enrollment, e.g., a mobile application, a magnetic card, etc. 
     In one implementation, a user may configure transaction restriction parameters via a consumer enrollment user interface. For example, in one implementation, an electronic wallet user may receive an invitation from UEP to sign up with UEP service, and following a link provided in the invitation (e.g., an email, etc.), the user may provide registration information in a registration form. 
     In one implementation, a user may configure payment methods and alerts with UEP. For example, the user may add a payment account to the wallet, and register for timely alerts with transactions associated with the payment account. In one implementation, the user may establish customized rules for triggers of a transaction alert. For example, an alert message may be triggered when a susceptible transaction occurs as the transaction amount exceeds a maximum one time transaction amount (e.g., $500.00, etc.). For another example, an alert may be triggered when a transaction occurs within a susceptible time range (e.g., all transactions occurring between 2 am-6 am, etc.). For another example, an alert may be triggered when the frequency of transactions exceeds a maximum number of transactions per day (e.g., 20 per day, etc.). For further examples, an alert may be triggered when the transacting merchant is one of a consumer specified susceptible merchants (e.g., Internet spam sites, etc.). For another example, an alert may be triggered when the type of the transaction is a blocked transaction type (e.g., a user may forbid wallet transactions at a gas station for gas fill, etc.). 
     In one implementation, the user may subscribe to UEP alerts by selecting alert channels. For example, the user may providing his mobile number, email address, mailing address and/or the like to UEP, and subscribe to alerts via email, text messages, consumer service calls, mail, and/or the like. In one implementation, the user may configure rules and subscription channels for different payment account associated with the electronic wallet. 
     In one implementation, upon receiving user configured parameters via a user interface, UEP (e.g., a Visa Wallet network) may provide a (Secure) Hypertext Transfer Protocol (“HTTP(S)”) PUT message including the user leash parameters in the form of data formatted according to the eXtensible Markup Language (“XML”). Below is an example HTTP(S) PUT message including an XML-formatted user leash parameters for storage in a database:

     In one implementation, upon configuring the leash parameters, when a consumer shops with a merchant (e.g., a shopping site, etc.), the payment processor network may forward the purchasing request to Visa network, which may apply the consumer&#39;s UEP enrollment with the electronic wallet (e.g., Visa wallet network, etc.). For example, in one implementation, the UEP may retrieve the user leash parameters, and inspect the transaction amount, transaction type, transaction frequency, and/or the like of the received transaction request based on the leash parameters. 
     In one implementation, if the proposed transaction triggers an alert, UEP may generate an alert message, e.g., by providing a (Secure) Hypertext Transfer Protocol (“HTTP(S)”) PUT message including the alert content in the form of data formatted according to the XML. Below is an example HTTP(S) PUT message including an XML-formatted alert:

     In one implementation, the UEP may also generate a message and send it to the issuing bank, e.g., the user&#39;s bank that issues the payment account, etc., to alert the issuing bank not to credit funds to the merchant unless a clearance message is received subsequently. 
     With reference to  FIG. 16B , in some implementations, the virtual wallet application may provide an interface via which user may efficiently set purchase controls for transactions. For example, the user may enter a purchase controls settings screen (“JDOE1”)  1611 , wherein the user may add restriction parameters to the purchase control setting. For example, the user interface on the left of  FIG. 16B  shows a purchase control that only allows in-person (see  1612 ) transactions below $50 (see  1613 ) to be made from US or Taiwan (see  1614 ), when made for clothes or shoes (see  1615 ), and not more than once a month (see  1616 ), and given that the user&#39;s overall spend for the time frame (1 mo) is less than $1500 (see  1617 ). Such parametric restrictions may be imposed using the user interface elements  1618  (e.g., to select a parameter) and  1619  (e.g., to enter a value corresponding to the parameter). In some situations, the virtual wallet may provide a graphical user interface component (e.g.,  1622 ) to facilitate user input entry. For example, the virtual wallet may display a map of the world when the user wishes to place a geographic restriction on a purchase control, and the user may touch the map at the appropriate sport (e.g.,  1623 ,  1624 ) to set the locations from which transaction may be allowed (or alternatively, blocked). In some implementations the virtual wallet may also allow the user to manually enter the value (see  1626 ), instead of utilizing the visual touch-based GUI component provided by the virtual wallet application. 
     With reference to  FIG. 16C , in some implementations, the virtual wallet application may allow a user to manage privacy settings  1631  associated with the users&#39; use of the wallet. For example, the user may be able to specify the information (e.g.,  1632 - 1637 ) about the user that may be shared during the course of a purchase transaction. For example, in the illustration, the user has allowed the virtual wallet application to share the user&#39;s name, and social circle ( 1632 ). The user has not yet set a preference for sharing the user&#39;s address; thus it may take a default value of medium (e.g., if the risk in the transaction is assessed by the UEP as being above medium, then the UEP may cloak the user&#39;s address during the transaction) depending on the type of transaction, in some implementations. The user has explicitly opted against sharing the user&#39;s account numbers (e.g., the user wishes for the payment network to cloak the user&#39;s account number during the transaction), and the user&#39;s live GPS location (see  1638 ). 
       FIG. 17A  shows a logic flow diagram illustrating example aspects of configuring virtual wallet application settings in some embodiments of the UEP, e.g., a Virtual Wallet Settings Configuration (“VWSC”) component  1700 . In some implementations, a user may desire to modify a setting within the user&#39;s virtual wallet application and/or within a virtual wallet application that has a relationship to the user&#39;s wallet (e.g., bonded wallet is a child wallet of the user&#39;s wallet). The user may provide input to a user device,  1701 , indicating the desire to modify a wallet setting. Upon determining that the user desires to modify a wallet setting (see  1702 - 1703 ), the device may determine whether the user request is for modification of the user&#39;s wallet, or for modification of a wallet bonded to the user&#39;s wallet. In some implementations, the wallet application may require the user to enter a password or answer a challenge question successfully before allowing the user to modify a user setting. Further, in some implementations, the device may, if the user desires to modify the wallet settings of a bonded wallet (see  1705 ), the device may determine whether the user is authorized to do so,  1706 . For example, the device may determine the type of relationship between the user&#39;s wallet and the bonded wallet; whether the bonded wallet (or its user) is required to provide permission before the wallet settings can be modified; and/or the like. In implementations requiring authorization from the bonded wallet user, the device may provide a request to a device of the bonded wallet user (e.g., via a server system storing network addresses for the devices of each user utilizing a virtual wallet). Upon determining that the user&#39;s wallet has authorization to modify the settings of the bonded wallet (see  1707 ), the device may identify a type of modification that the user desires to perform,  1708 . In some implementations, whether the user is authorized to modify a wallet setting may depend on the wallet setting the user desires to modify, in which case the identification of the type of modification may be performed before determining whether the user is authorized to modify the wallet setting. Based on the type of modification requested by the user, the device may provide a graphical user interface (GUI) component (see, e.g., geographical map for marking countries from which transactions may be initiated for a particular purchase control setting,  FIG. 16B  [center]) to facilitate user entry of the modification to a wallet setting,  1709 . The device may obtain the user setting value input via the GUI component,  1710 . Where the modification involves a bonded wallet, the device may optionally provide a notification of modification of a setting involving the bonded wallet,  1711 . The device may optionally store the modification of the wallet setting in a database, e.g., in a local database or a cloud storage database,  1712 . 
       FIGS. 17B-C  show logic flow diagrams illustrating example aspects of implementing purchase controls settings in some embodiments of the UEP, e.g., a Purchase Controls Settings (“PCS”) component  1720 . With reference to  FIG. 17B , in some implementations, a user may desire to generate a purchase control setting to monitor and/or restrict transactions of a specific character from being processed by the UEP. The user may provide such an indication into a user device executing a virtual wallet application for the user,  1721 . In response, the device may provide a GUI component for the user to select a parameter according to which to restrict transactions initiated from the virtual wallet of the user,  1722  (see, e.g., scroll wheels of  FIG. 16B ). The user may utilize the GUI component to select a restriction parameter,  1723 . Based on the restriction parameter selected (e.g., geographical location, transaction value, transaction card, product category, time, date, currency, account balance(s), etc.), the device may identify, e.g., by querying a database, a GUI component to provide the user for facilitate the user providing a value associated with the restriction parameter (see, e.g., world map of  FIG. 16B  [center]),  1724 . The device may provide the identified GUI component to the user,  1725 . Using the GUI component, the user may provide a value for the restriction parameter,  1726 . In response, the device may generate a data snippet including an identification of a restriction parameter, and an associated value for the restriction parameter,  1727 . For example, the data snippet may be formatted as an XML data structure. In some implementations, the data structure may also include an indication of whether the restriction parameter value represents an upper bound or lower bound of the range of allowed values for that parameter. The device may append the data structure for the restriction parameter to a data structure for the overall purchase control setting,  1727 . In some implementations, the device may determine whether the user desires to enter more such restriction parameters, and may facilitate the user entering such restriction parameters on top of any previously provided restriction parameters (see  1728 - 1729 ). Upon obtaining all restriction parameters for a given purchase control setting, the device may store the finalized purchase control setting to a database (e.g., a local database, a cloud storage database, etc.),  1730 . 
     With reference to  FIG. 17C , in some implementations, a user may desire to enter into a purchase transaction. The user may provide an input into user device executing a virtual wallet application indicative of the user&#39;s desire to enter into the purchase transaction,  1731 . In response, the device may identify the parameters of the transaction (e.g., geographical location, transaction value, transaction card, product category, time, date, cart, wallet type [bonded, unbonded], currency, account balance(s) around the time of initiation of the transaction, etc.),  1732 . The device may query a database for purchase control settings that may apply to the purchase transaction request,  1733 . For example, these could include rules set by a bonded wallet user who has authorization to set purchase controls on the user&#39;s wallet. The device may process each purchase control setting to ensure that no setting is violated. In alternative schemes, the device may process purchase control settings until at least one purchase control setting permits the purchase transaction to be performed (or the purchase transaction may be denied if no setting permits it), see  1734 . The device may select a purchase control setting, and extract the restriction parameters and their associated value from the purchase control setting data structure. For example, the device may use a parser similar to the example parsers described below in the discussion with reference to  FIG. 61 . The device may select a restriction parameter-value pair,  1736 , and determine whether the transaction parameters violate the restriction parameter value,  1737 . If the restriction is violated ( 1738 , option “Yes”), the device may deny the purchase transaction request. Otherwise, the device may check each restriction parameter in the purchase control setting (see  1739 ) in a similar procedure to that described above. If the purchase control setting does not restrict the transaction, the device may execute similar procedure for all the other purchase control settings, unless one of the settings is violated (or, in the alternative scheme, if at least one purchase control setting permits the purchase transaction) (see  1740 ). If the device determines that the purchase transaction is permitted by the purchase control settings of the user and/or bonded wallet users ( 1740 , option “No”), the device may generate a card authorization request,  1741 , and provide the card authorization request for purchase transaction authorization (see  FIG. 57A ). 
     Centralized Personal Information Platform 
       FIG. 18  shows a block diagram illustrating example aspects of a centralized personal information platform in some embodiments of the UEP. In various scenarios, originators  1811  such as merchants  1811   b , consumers  1811   c , account issuers, acquirers  1811   a , and/or the like, desire to utilize information from payment network systems for enabling various features for consumers. Such features may include application services  1812  such as alerts  1812   a , offers  1812   c , money transfers  1812   n , fraud detection  1812   b , and/or the like. In some embodiments of the UEP, such originators may request data to enable application services from a common, secure, centralized information platform including a consolidated, cross-entity profile-graph database  1801 . For example, the originators may submit complex queries to the UEP in a structure format, such as the example below. In this example, the query includes a query to determine a location (e.g., of a user), determine the weather associated with the location, perform analyses on the weather data, and provide an exploded graphical view of the results of the analysis:

     In some embodiments, the UEP may provide access to information on a need-to-know basis to ensure the security of data of entities on which the UEP stores information. Thus, in some embodiments, access to information from the centralized platform may be restricted based on the originator as well as application services for which the data is requested. In some embodiments, the UEP may thus allow a variety of flexible application services to be built on a common database infrastructure, while preserving the integrity, security, and accuracy of entity data. In some implementations, the UEP may generate, update, maintain, store and/or provide profile information on entities, as well as a social graph that maintains and updates interrelationships between each of the entities stored within the UEP. For example, the UEP may store profile information on an issuer bank  1802   a  (see profile  1803   a ), a acquirer bank  1802   b  (see profile  1803   b ), a consumer  1802   c  (see profile  1803   c ), a user  1802   d  (see profile  1803   d ), a merchant  1802   e  (see profile  1803   e ), a second merchant  1802   f  (see profile  1803   f ). The UEP may also store relationships between such entities. For example, the UEP may store information on a relationship of the issuer bank  1802   a  to the consumer  1802   c  shopping at merchant  1802   e , who in turn may be related to user  1802   d , who might bank at the back  1802   b  that serves as acquirer for merchant  1802   f.    
       FIGS. 19A-F  show block diagrams illustrating example aspects of data models within a centralized personal information platform in some embodiments of the UEP. In various embodiments, the UEP may store a variety of attributes of entities according to various data models. A few non-limiting example data models are provided below. In some embodiments, the UEP may store user profile attributes. For example, a user profile model may store user identifying information  1901 , user aliases  1902 , email addresses  1903 , phone numbers  1904 , addresses  1905 , email address types  1906 , address types  1907 , user alias types  1908 , notification statuses  1909 , ISO country  1910 , phone number types  1911 , contract information with the UEP  1912 , user authorization status  1913 , user profile status  1914 , security answer  1915 , security questions  1916 , language  1917 , time zone  1918 , and/or the like, each of the above field types including one or more fields and field values. As another example, a user financial attributes model may store user identifying information  1920 , user financial account information  1921 , account contract information  1922 , user financial account role  1923 , financial account type  1924 , financial account identifying information  1925 , contract information  1926 , financial account validation  1927 , financial account validation type  1928 , and/or the like. As another example, a user payment card attributes data model may include field types such s, but not limited to: user identifying information  1930 , user financial account information  1931 , user financial account role  1932 , account consumer applications  1933 , user consumer application  1934 , financial account type  1935 , financial account validation type  1936 , financial account information  1937 , consumer application information  1938 , consumer application provider information  1939 , and/or the like. As another example, a user services attributes data model may include field types such as, but not limited to: user identifying information  1940 , user alias  1941 , consumer application user alias status  1942 , user alias status  1943 , status change reason code  1944 , user contract  1945 , contract information  1946 , user service attribute value  1947 , consumer application attributes  1948 , account service attribute value, account contract  1950 , user profile status  1951 , contract business role  1952 , contract business  1953 , client information  1954 , contract role  1955 , consumer application  1956 , user activity audit  1957 , login results  1958 , and/or the like. As another example, a user services usage attributes data model may include field types such as, but not limited to: user identifying information  1960 , user alias  1961 , consumer application user alias status  1962 , status change reason code  1963 , user alias status  1964 , user consumer application  1965 , user login audit  1966 , login result  1967 , account service attribute value  1968 , account consumer application  1969 , consumer application  1970 , consumer application provider  1971 , login result  1972 , and/or the like. As another example, a user graph attributes data model may include field types such as, but not limited to: user identifying information  1980 , user contact  1981 , consumer application user alias status  1982 , relationship  1983 , and/or the like. In some embodiments, the UEP may store each object (e.g., user, merchant, issuer, acquirer, IP address, household, etc.) as a node in graph database, and store data with respect to each node in a format such as the example format provided below:

       FIG. 20  shows a block diagram illustrating example UEP component configurations in some embodiments of the UEP. In some embodiments, the UEP may aggregate data from a variety of sources to generate centralized personal information. The may also aggregate various types of data in order to generate the centralized personal information. For example, the UEP may utilize search results aggregation component(s)  2001  (e.g., such as described in  FIGS. 21-22 ) to aggregate search results from across a wide range of computer networked systems, e.g., the Internet. As another example, the UEP may utilize transaction data aggregation component(s)  2002  (e.g., such as described in  FIGS. 23-26 ) to aggregate transaction data, e.g., from transaction processing procedure by a payment network. As another example, the UEP may utilize service usage data aggregation component(s)  2003  (e.g., such as described in  FIGS. 23-26 ) to aggregate data on user&#39;s usage of various services associated with the UEP. As another example, the UEP may utilize enrollment data component(s)  2004  (e.g., such as described in  FIGS. 23-26 ) to aggregate data on user&#39;s enrollment into various services associated with the UEP. As another example, the UEP may utilize social data aggregation component(s)  2003  (e.g., such as described in  FIGS. 27-28 ) to aggregate data on user&#39;s usage of various social networking services accessible by the UEP. 
     In some embodiments, the UEP may acquire the aggregated data, and normalize the data into formats that are suitable for uniform storage, indexing, maintenance, and/or further processing via data record normalization component(s)  2006  (e.g., such as described in  FIG. 31 ). The UEP may extract data from the normalized data records, and recognize data fields, e.g., the UEP may identify the attributes of each field of data included in the normalized data records via data field recognition component(s)  2007  (e.g., such as described in  FIG. 32 ). For example, the UEP may identify names, user ID(s), addresses, network addresses, comments and/or specific words within the comments, images, blog posts, video, content within the video, and/or the like from the aggregated data. In some embodiments, for each field of data, the UEP may classify entity types associated with the field of data, as well as entity identifiers associated with the field of data, e.g., via component(s)  2008  (e.g., such as described in  FIG. 33 ). For example, the UEP may identify an Internet Protocol (IP) address data field to be associated with a user ID john.q.public (consumer entity type), a user John Q. Public (consumer entity type), a household (the Public household—a multi-consumer entity type/household entity type), a merchant entity type with identifier Acme Merchant Store, Inc. from which purchases are made from the IP address, an Issuer Bank type with identifier First National Bank associated with the purchases made from the IP address, and/or the like. In some embodiments, the UEP may utilize the entity types and entity identifiers to correlate entities across each other, e.g., via cross-entity correlation component(s)  2009  (e.g., such as described in  FIG. 34 ). For example, the UEP may identify, from the aggregated data, that a household entity with identifier H123 may include a user entity with identifier John Q. Public and social identifier john.q.public@facebook.com, a second user entity with identifier Jane P. Doe with social identifier jpdoe@twitter.com, a computer entity with identifier IP address 192.168.4.5, a card account entity with identifier ****1234, a bank issuer entity with identifier AB23145, a merchant entity with identifier Acme Stores, Inc. where the household sub-entities make purchases, and/or the like. In some embodiments, the UEP may utilize the entity identifiers, data associated with each entity and/or correlated entities to identify associations to other entities, e.g., via entity attribute association component(s)  2010  (e.g., such as described in  FIG. 35 ). For example, the UEP may identify specific purchases made via purchase transactions by members of the household, and thereby identify attributes of members of the household on the basis of the purchases in the purchase transactions made by members of the household. Based on such correlations and associations, the UEP may update a profile for each entity identified from the aggregated data, as well as a social graph interrelating the entities identified in the aggregated data, e.g., via entity profile-graph updating component(s)  2011  (e.g., such as described in  FIG. 36 ). In some embodiments, the updating of profile and/or social graphs for an entity may trigger a search for additional data that may be relevant to the newly identified correlations and associations for each entity, e.g., via search term generation component(s)  2013 - 2014  (e.g., such as described in  FIG. 37 ). For example, the updating of a profile and/or social graph may trigger searches across the Internet, social networking websites, transaction data from payment networks, services enrolled into and/or utilized by the entities, and/or the like. In some embodiments, such updating of entity profiles and/or social graphs may be performed continuously, periodically, on-demand, and/or the like. 
       FIG. 21  shows a data flow diagram illustrating an example search result aggregation procedure in some embodiments of the UEP. In some implementations, the pay network server may obtain a trigger to perform a search. For example, the pay network server may periodically perform a search update of its aggregated search database, e.g.,  2110 , with new information available from a variety of sources, such as the Internet. As another example, a request for on-demand search update may be obtained as a result of a user wishing to enroll in a service, for which the pay network server may facilitate data entry by providing an automated web form filling system using information about the user obtained from the search update. In some implementations, the pay network server may parse the trigger to extract keywords using which to perform an aggregated search. The pay network server may generate a query for application programming interface (API) templates for various search engines (e.g., Google™, Bing®, AskJeeves, market data search engines, etc.) from which to collect data for aggregation. The pay network server may query, e.g.,  2112 , a pay network database, e.g.,  2107 , for search API templates for the search engines. For example, the pay network server may utilize PHP/SQL commands similar to the examples provided above. The database may provide, e.g.,  2113 , a list of API templates in response. Based on the list of API templates, the pay network server may generate search requests, e.g.,  2114 . The pay network server may issue the generated search requests, e.g.,  2115   a - c , to the search engine servers, e.g.,  2101   a - c . For example, the pay network server may issue PHP commands to request the search engine for search results. An example listing of commands to issue search requests  2115   a - c , substantially in the form of PHP commands, is provided below:

                 $body = curl_exec($ch); 
               
               
                 curl_close($ch); 
               
               
                 // Obtain, parse search results 
               
               
                 $json = json_decode($body); 
               
               
                 ?&gt; 
               
               
                   
               
            
           
         
       
     
     In some embodiments, the search engine servers may query, e.g.,  2117   a - c , their search databases, e.g.,  2102   a - c , for search results falling within the scope of the search keywords. In response to the search queries, the search databases may provide search results, e.g.,  2118   a - c , to the search engine servers. The search engine servers may return the search results obtained from the search databases, e.g.,  2119   a - c , to the pay network server making the search requests. An example listing of search results  2119   a - c , substantially in the form of JavaScript Object Notation (JSON)-formatted data, is provided below:

     In some embodiments, the pay network server may store the aggregated search results, e.g.,  2120 , in an aggregated search database, e.g.,  2110 . 
       FIG. 22  shows a logic flow diagram illustrating example aspects of aggregating search results in some embodiments of the UEP, e.g., a Search Results Aggregation (“SRA”) component  2200 . In some implementations, the pay network server may obtain a trigger to perform a search, e.g.,  2201 . For example, the pay network server may periodically perform a search update of its aggregated search database with new information available from a variety of sources, such as the Internet. As another example, a request for on-demand search update may be obtained as a result of a user wishing to enroll in a service, for which the pay network server may facilitate data entry by providing an automated web form filling system using information about the user obtained from the search update. In some implementations, the pay network server may parse the trigger, e.g.,  2202 , to extract keywords using which to perform an aggregated search. The pay network server may determine the search engines to search, e.g.,  2203 , using the extracted keywords. Then, the pay network server may generate a query for application programming interface (API) templates for the various search engines (e.g., Google™, Bing®, AskJeeves, market data search engines, etc.) from which to collect data for aggregation, e.g.,  2204 . The pay network server may query, e.g.,  2205 , a pay network database for search API templates for the search engines. For example, the pay network server may utilize PHP/SQL commands similar to the examples provided above. The database may provide, e.g.,  2205 , a list of API templates in response. Based on the list of API templates, the pay network server may generate search requests, e.g.,  2206 . The pay network server may issue the generated search requests to the search engine servers. The search engine servers may parse the obtained search results(s), e.g.,  2207 , and query, e.g.,  2208 , their search databases for search results falling within the scope of the search keywords. In response to the search queries, the search databases may provide search results, e.g.,  2209 , to the search engine servers. The search engine servers may return the search results obtained from the search databases, e.g.,  2210 , to the pay network server making the search requests. The pay network server may generate, e.g.,  2211 , and store the aggregated search results, e.g.,  2212 , in an aggregated search database. 
       FIGS. 23A-D  show data flow diagrams illustrating an example card-based transaction execution procedure in some embodiments of the UEP. In some implementations, a user, e.g.,  2301 , may desire to purchase a product, service, offering, and/or the like (“product”), from a merchant. The user may communicate with a merchant server, e.g.,  2303 , via a client such as, but not limited to: a personal computer, mobile device, television, point-of-sale terminal, kiosk, ATM, and/or the like (e.g.,  2302 ). For example, the user may provide user input, e.g., purchase input  2311 , into the client indicating the user&#39;s desire to purchase the product. In various implementations, the user input may include, but not be limited to: keyboard entry, card swipe, activating a RFID/NFC enabled hardware device (e.g., electronic card having multiple accounts, smartphone, tablet, etc.), mouse clicks, depressing buttons on a joystick/game console, voice commands, single/multi-touch gestures on a touch-sensitive interface, touching user interface elements on a touch-sensitive display, and/or the like. For example, the user may direct a browser application executing on the client device to a website of the merchant, and may select a product from the website via clicking on a hyperlink presented to the user via the website. As another example, the client may obtain track 1 data from the user&#39;s card (e.g., credit card, debit card, prepaid card, charge card, etc.), such as the example track 1 data provided below: 
     
       
         
           
               
             
               
                   
               
             
            
               
                 %B123456789012345{circumflex over ( )}PUBLIC/J.Q.{circumflex over ( )}99011200000000000000**901******?* 
               
               
                 (wherein ‘123456789012345’ is the card number of ‘J.Q. Public’ and has a CVV number 
               
            
           
           
               
               
            
               
                   
                 of 901. ‘990112’ is a service code, and *** represents decimal digits which change 
               
               
                   
                 randomly each time the card is used.) 
               
               
                   
                   
               
            
           
         
       
     
     In some implementations, the client may generate a purchase order message, e.g.,  2312 , and provide, e.g.,  2313 , the generated purchase order message to the merchant server. For example, a browser application executing on the client may provide, on behalf of the user, a (Secure) Hypertext Transfer Protocol (“HTTP(S)”) GET message including the product order details for the merchant server in the form of data formatted according to the eXtensible Markup Language (“XML”). Below is an example HTTP(S) GET message including an XML-formatted purchase order message for the merchant server: 
     
       
         
           
               
             
               
                   
               
             
            
               
                 GET /purchase.php HTTP/1.1

     In some implementations, the merchant server may obtain the purchase order message from the client, and may parse the purchase order message to extract details of the purchase order from the user. The merchant server may generate a card query request, e.g.,  2314  to determine whether the transaction can be processed. For example, the merchant server may attempt to determine whether the user has sufficient funds to pay for the purchase in a card account provided with the purchase order. The merchant server may provide the generated card query request, e.g.,  2315 , to an acquirer server, e.g.,  2304 . For example, the acquirer server may be a server of an acquirer financial institution (“acquirer”) maintaining an account of the merchant. For example, the proceeds of transactions processed by the merchant may be deposited into an account maintained by the acquirer. In some implementations, the card query request may include details such as, but not limited to: the costs to the user involved in the transaction, card account details of the user, user billing and/or shipping information, and/or the like. For example, the merchant server may provide a HTTP(S) POST message including an XML-formatted card query request similar to the example listing provided below:

     In some implementations, the acquirer server may generate a card authorization request, e.g.,  2316 , using the obtained card query request, and provide the card authorization request, e.g.,  2317 , to a pay network server, e.g.,  2305 . For example, the acquirer server may redirect the HTTP(S) POST message in the example above from the merchant server to the pay network server. 
     In some implementations, the pay network server may determine whether the user has enrolled in value-added user services. For example, the pay network server may query  2318  a database, e.g., pay network database  2307 , for user service enrollment data. For example, the server may utilize PHP/SQL commands similar to the example provided above to query the pay network database. In some implementations, the database may provide the user service enrollment data, e.g.,  2319 . The user enrollment data may include a flag indicating whether the user is enrolled or not, as well as instructions, data, login URL, login API call template and/or the like for facilitating access of the user-enrolled services. For example, in some implementations, the pay network server may redirect the client to a value-add server (e.g., such as a social network server where the value-add service is related to social networking) by providing a HTTP(S) REDIRECT 300 message, similar to the example below:

     In some implementations, the pay network server may provide payment information extracted from the card authorization request to the value-add server as part of a value add service request, e.g.,  2320 . For example, the pay network server may provide a HTTP(S) POST message to the value-add server, similar to the example below:

     In some implementations, the value-add server may provide a service input request, e.g.,  2321 , to the client. For example, the value-add server may provide a HTML input/login form to the client. The client may display, e.g.,  2322 , the login form for the user. In some implementations, the user may provide login input into the client, e.g.,  2323 , and the client may generate a service input response, e.g.,  2324 , for the value-add server. In some implementations, the value-add server may provide value-add services according to user value-add service enrollment data, user profile, etc., stored on the value-add server, and based on the user service input. Based on the provision of value-add services, the value-add server may generate a value-add service response, e.g.,  2326 , and provide the response to the pay network server. For example, the value-add server may provide a HTTP(S) POST message similar to the example below:

     In some implementations, upon receiving the value-add service response from the value-add server, the pay network server may extract the enrollment service data from the response for addition to a transaction data record. In some implementations, the pay network server may forward the card authorization request to an appropriate pay network server, e.g.,  2328 , which may parse the card authorization request to extract details of the request. Using the extracted fields and field values, the pay network server may generate a query, e.g.,  2329 , for an issuer server corresponding to the user&#39;s card account. For example, the user&#39;s card account, the details of which the user may have provided via the client-generated purchase order message, may be linked to an issuer financial institution (“issuer”), such as a banking institution, which issued the card account for the user. An issuer server, e.g.,  2308   a - n , of the issuer may maintain details of the user&#39;s card account. In some implementations, a database, e.g., pay network database  2307 , may store details of the issuer servers and card account numbers associated with the issuer servers. For example, the database may be a relational database responsive to Structured Query Language (“SQL”) commands. The pay network server may execute a hypertext preprocessor (“PHP”) script including SQL commands to query the database for details of the issuer server. An example PHP/SQL command listing, illustrating substantive aspects of querying the database, is provided below: 
     
       
         
           
               
             
               
                   
               
             
            
               
                 &lt;?PHP 
               
               
                 header(‘Content-Type: text/plain’); 
               
               
                 mysql_connect(“254.93.179.112”,$DBserver,$password);  
               
               
                 // access database server 
               
               
                 mysql_select_db(“ISSUERS.SQL”); // select database table to search 
               
               
                 //create query for issuer server data 
               
               
                 $query = “SELECT  
               
               
                 issuer_name issuer_address issuer_id ip_address max_address 
               
               
                  auth_key port_num security_settings_list FROM IssuerTable  
               
               
                  WHERE account_num LIKE ‘%’ $accountnum”; 
               
               
                 $result = mysql_query($query); // perform the search query 
               
               
                 mysql_close(“ISSUERS.SQL”); // close database access 
               
               
                 ?&gt; 
               
               
                   
               
            
           
         
       
     
     In response to obtaining the issuer server query, e.g.,  2329 , the pay network database may provide, e.g.,  2330 , the requested issuer server data to the pay network server. In some implementations, the pay network server may utilize the issuer server data to generate a forwarding card authorization request, e.g.,  2331 , to redirect the card authorization request from the acquirer server to the issuer server. The pay network server may provide the card authorization request, e.g.,  2332   a - n , to the issuer server. In some implementations, the issuer server, e.g.,  2308   a - n , may parse the card authorization request, and based on the request details may query  2333   a - n  database, e.g., user profile database  2309   a - n , for data of the user&#39;s card account. For example, the issuer server may issue PHP/SQL commands similar to the example provided below: 
     
       
         
           
               
             
               
                   
               
             
            
               
                 &lt;?PHP 
               
               
                 header(‘Content-Type: text/plain’); 
               
               
                 mysql_connect(“254.93.179.112”,$DBserver,$password);  
               
               
                 // access database server 
               
               
                 mysql_select_db(“USERS.SQL”); // select database table to search 
               
               
                 //create query for user data 
               
               
                 $query = “SELECT user_id user_name user_balance account_type  
               
               
                 FROM UserTable 
               
               
                  WHERE account_num LIKE ‘%’ $accountnum”; 
               
               
                 $result = mysql_query($query); // perform the search query 
               
               
                 mysql_close(“USERS.SQL”); // close database access 
               
               
                 ?&gt; 
               
               
                   
               
            
           
         
       
     
     In some implementations, on obtaining the user data, e.g.,  2334   a - n , the issuer server may determine whether the user can pay for the transaction using funds available in the account, e.g.,  2335   a - n . For example, the issuer server may determine whether the user has a sufficient balance remaining in the account, sufficient credit associated with the account, and/or the like. If the issuer server determines that the user can pay for the transaction using the funds available in the account, the server may provide an authorization message, e.g.,  2336   a - n , to the pay network server. For example, the server may provide a HTTP(S) POST message similar to the examples above. 
     In some implementations, the pay network server may obtain the authorization message, and parse the message to extract authorization details. Upon determining that the user possesses sufficient funds for the transaction, the pay network server may generate a transaction data record from the card authorization request it received, and store, e.g.,  2339 , the details of the transaction and authorization relating to the transaction in a database, e.g., pay network database  2307 . For example, the pay network server may issue PHP/SQL commands similar to the example listing below to store the transaction data in a database:

     In some implementations, the pay network server may forward the authorization message, e.g.,  2340 , to the acquirer server, which may in turn forward the authorization message, e.g.,  2340 , to the merchant server. The merchant may obtain the authorization message, and determine from it that the user possesses sufficient funds in the card account to conduct the transaction. The merchant server may add a record of the transaction for the user to a batch of transaction data relating to authorized transactions. For example, the merchant may append the XML data pertaining to the user transaction to an XML data file comprising XML data for transactions that have been authorized for various users, e.g.,  2341 , and store the XML data file, e.g.,  2342 , in a database, e.g., merchant database  2304 . For example, a batch XML data file may be structured similar to the example XML data structure template provided below:

     In some implementations, the server may also generate a purchase receipt, e.g.,  2343 , and provide the purchase receipt to the client. The client may render and display, e.g.,  2344 , the purchase receipt for the user. For example, the client may render a webpage, electronic message, text/SMS message, buffer a voicemail, emit a ring tone, and/or play an audio message, etc., and provide output including, but not limited to: sounds, music, audio, video, images, tactile feedback, vibration alerts (e.g., on vibration-capable client devices such as a smartphone etc.), and/or the like. 
     With reference to  FIG. 23C , in some implementations, the merchant server may initiate clearance of a batch of authorized transactions. For example, the merchant server may generate a batch data request, e.g.,  2345 , and provide the request, e.g.,  2346 , to a database, e.g., merchant database  2304 . For example, the merchant server may utilize PHP/SQL commands similar to the examples provided above to query a relational database. In response to the batch data request, the database may provide the requested batch data, e.g.,  2347 . The server may generate a batch clearance request, e.g.,  2348 , using the batch data obtained from the database, and provide, e.g.,  2341 , the batch clearance request to an acquirer server, e.g.,  2310 . For example, the merchant server may provide a HTTP(S) POST message including XML-formatted batch data in the message body for the acquirer server. The acquirer server may generate, e.g.,  2350 , a batch payment request using the obtained batch clearance request, and provide the batch payment request to the pay network server, e.g.,  2351 . The pay network server may parse the batch payment request, and extract the transaction data for each transaction stored in the batch payment request, e.g.,  2352 . The pay network server may store the transaction data, e.g.,  2353 , for each transaction in a database, e.g., pay network database  2307 . For each extracted transaction, the pay network server may query, e.g.,  2354 - 2355 , a database, e.g., pay network database  2307 , for an address of an issuer server. For example, the pay network server may utilize PHP/SQL commands similar to the examples provided above. The pay network server may generate an individual payment request, e.g.,  2356 , for each transaction for which it has extracted transaction data, and provide the individual payment request, e.g.,  2357 , to the issuer server, e.g.,  2308 . For example, the pay network server may provide a HTTP(S) POST request similar to the example below:

     In some implementations, the issuer server may generate a payment command, e.g.,  2358 . For example, the issuer server may issue a command to deduct funds from the user&#39;s account (or add a charge to the user&#39;s credit card account). The issuer server may issue a payment command, e.g.,  2359 , to a database storing the user&#39;s account information, e.g., user profile database  2308 . The issuer server may provide a funds transfer message, e.g.,  2360 , to the pay network server, which may forward, e.g.,  2361 , the funds transfer message to the acquirer server. An example HTTP(S) POST funds transfer message is provided below:

     In some implementations, the acquirer server may parse the funds transfer message, and correlate the transaction (e.g., using the request ID field in the example above) to the merchant. The acquirer server may then transfer the funds specified in the funds transfer message to an account of the merchant, e.g.,  2362 . 
       FIGS. 24A-E  show logic flow diagrams illustrating example aspects of card-based transaction execution, resulting in generation of card-based transaction data and service usage data, in some embodiments of the UEP, e.g., a Card-Based Transaction Execution (“CTE”) component  2400 . In some implementations, a user may provide user input, e.g.,  2401 , into a client indicating the user&#39;s desire to purchase a product from a merchant. The client may generate a purchase order message, e.g.,  2402 , and provide the generated purchase order message to the merchant server. In some implementations, the merchant server may obtain, e.g.,  2403 , the purchase order message from the client, and may parse the purchase order message to extract details of the purchase order from the user. Example parsers that the merchant client may utilize are discussed further below with reference to  FIG. 61 . The merchant may generate a product data query, e.g.,  2404 , for a merchant database, which may in response provide the requested product data, e.g.,  2405 . The merchant server may generate a card query request using the product data, e.g.,  2404 , to determine whether the transaction can be processed. For example, the merchant server may process the transaction only if the user has sufficient funds to pay for the purchase in a card account provided with the purchase order. The merchant server may optionally provide the generated card query request to an acquirer server. The acquirer server may generate a card authorization request using the obtained card query request, and provide the card authorization request to a pay network server. 
     In some implementations, the pay network server may determine whether the user has enrolled in value-added user services. For example, the pay network server may query a database, e.g.,  2407 , for user service enrollment data. For example, the server may utilize PHP/SQL commands similar to the example provided above to query the pay network database. In some implementations, the database may provide the user service enrollment data, e.g.,  2408 . The user enrollment data may include a flag indicating whether the user is enrolled or not, as well as instructions, data, login URL, login API call template and/or the like for facilitating access of the user-enrolled services. For example, in some implementations, the pay network server may redirect the client to a value-add server (e.g., such as a social network server where the value-add service is related to social networking) by providing a HTTP(S) REDIRECT 300 message. In some implementations, the pay network server may provide payment information extracted from the card authorization request to the value-add server as part of a value add service request, e.g.,  2410 . 
     In some implementations, the value-add server may provide a service input request, e.g.,  2411 , to the client. The client may display, e.g.,  2412 , the input request for the user. In some implementations, the user may provide input into the client, e.g.,  2413 , and the client may generate a service input response for the value-add server. In some implementations, the value-add server may provide value-add services according to user value-add service enrollment data, user profile, etc., stored on the value-add server, and based on the user service input. Based on the provision of value-add services, the value-add server may generate a value-add service response, e.g.,  2417 , and provide the response to the pay network server. In some implementations, upon receiving the value-add service response from the value-add server, the pay network server may extract the enrollment service data from the response for addition to a transaction data record, e.g.,  2419 - 2420 . 
     With reference to  FIG. 24B , in some implementations, the pay network server may obtain the card authorization request from the acquirer server, and may parse the card authorization request to extract details of the request, e.g.,  2420 . Using the extracted fields and field values, the pay network server may generate a query, e.g.,  2421 - 2422 , for an issuer server corresponding to the user&#39;s card account. In response to obtaining the issuer server query the pay network database may provide, e.g.,  2422 , the requested issuer server data to the pay network server. In some implementations, the pay network server may utilize the issuer server data to generate a forwarding card authorization request, e.g.,  2423 , to redirect the card authorization request from the acquirer server to the issuer server. The pay network server may provide the card authorization request to the issuer server. In some implementations, the issuer server may parse, e.g.,  2424 , the card authorization request, and based on the request details may query a database, e.g.,  2425 , for data of the user&#39;s card account. In response, the database may provide the requested user data. On obtaining the user data, the issuer server may determine whether the user can pay for the transaction using funds available in the account, e.g.,  2426 . For example, the issuer server may determine whether the user has a sufficient balance remaining in the account, sufficient credit associated with the account, and/or the like, but comparing the data from the database with the transaction cost obtained from the card authorization request. If the issuer server determines that the user can pay for the transaction using the funds available in the account, the server may provide an authorization message, e.g.,  2427 , to the pay network server. 
     In some implementations, the pay network server may obtain the authorization message, and parse the message to extract authorization details. Upon determining that the user possesses sufficient funds for the transaction (e.g.,  2430 , option “Yes”), the pay network server may extract the transaction card from the authorization message and/or card authorization request, e.g.,  2433 , and generate a transaction data record using the card transaction details. The pay network server may provide the transaction data record for storage, e.g.,  2434 , to a database. In some implementations, the pay network server may forward the authorization message, e.g.,  2435 , to the acquirer server, which may in turn forward the authorization message, e.g.,  2436 , to the merchant server. The merchant may obtain the authorization message, and parse the authorization message to extract its contents, e.g.,  2437 . The merchant server may determine whether the user possesses sufficient funds in the card account to conduct the transaction. If the merchant server determines that the user possess sufficient funds, e.g.,  2438 , option “Yes,” the merchant server may add the record of the transaction for the user to a batch of transaction data relating to authorized transactions, e.g.,  2439 - 2440 . The merchant server may also generate a purchase receipt, e.g.,  2441 , for the user. If the merchant server determines that the user does not possess sufficient funds, e.g.,  2438 , option “No,” the merchant server may generate an “authorization fail” message, e.g.,  2442 . The merchant server may provide the purchase receipt or the “authorization fail” message to the client. The client may render and display, e.g.,  2443 , the purchase receipt for the user. 
     In some implementations, the merchant server may initiate clearance of a batch of authorized transactions by generating a batch data request, e.g.,  2444 , and providing the request to a database. In response to the batch data request, the database may provide the requested batch data, e.g.,  2445 , to the merchant server. The server may generate a batch clearance request, e.g.,  2446 , using the batch data obtained from the database, and provide the batch clearance request to an acquirer server. The acquirer server may generate, e.g.,  2448 , a batch payment request using the obtained batch clearance request, and provide the batch payment request to a pay network server. The pay network server may parse, e.g.,  2449 , the batch payment request, select a transaction stored within the batch data, e.g.,  2450 , and extract the transaction data for the transaction stored in the batch payment request, e.g.,  2451 . The pay network server may generate a transaction data record, e.g.,  2452 , and store the transaction data, e.g.,  2453 , the transaction in a database. For the extracted transaction, the pay network server may generate an issuer server query, e.g.,  2454 , for an address of an issuer server maintaining the account of the user requesting the transaction. The pay network server may provide the query to a database. In response, the database may provide the issuer server data requested by the pay network server, e.g.,  2455 . The pay network server may generate an individual payment request, e.g.,  2456 , for the transaction for which it has extracted transaction data, and provide the individual payment request to the issuer server using the issuer server data from the database. In some implementations, the issuer server may obtain the individual payment request, and parse, e.g.,  2457 , the individual payment request to extract details of the request. Based on the extracted data, the issuer server may generate a payment command, e.g.,  2458 . For example, the issuer server may issue a command to deduct funds from the user&#39;s account (or add a charge to the user&#39;s credit card account). The issuer server may issue a payment command, e.g.,  2459 , to a database storing the user&#39;s account information. In response, the database may update a data record corresponding to the user&#39;s account to reflect the debit/charge made to the user&#39;s account. The issuer server may provide a funds transfer message, e.g.,  2460 , to the pay network server after the payment command has been executed by the database. 
     In some implementations, the pay network server may check whether there are additional transactions in the batch that need to be cleared and funded. If there are additional transactions, e.g.,  2461 , option “Yes,” the pay network server may process each transaction according to the procedure described above. The pay network server may generate, e.g.,  2462 , an aggregated funds transfer message reflecting transfer of all transactions in the batch, and provide, e.g.,  2463 , the funds transfer message to the acquirer server. The acquirer server may, in response, transfer the funds specified in the funds transfer message to an account of the merchant, e.g.,  2464 . 
       FIG. 25  shows a data flow diagram illustrating an example procedure to aggregate card-based transaction data in some embodiments of the UEP. In some implementations, the pay network server may determine a scope of data aggregation required to perform the analysis, e.g.,  2511 . The pay network server may initiate data aggregation based on the determined scope. The pay network server may generate a query for addresses of server storing transaction data within the determined scope. The pay network server may query, e.g.,  2512 , a pay network database, e.g.,  2507   a , for addresses of pay network servers that may have stored transaction data within the determined scope of the data aggregation. For example, the pay network server may utilize PHP/SQL commands similar to the examples provided above. The database may provide, e.g.,  2513 , a list of server addresses in response to the pay network server&#39;s query. Based on the list of server addresses, the pay network server may generate transaction data requests, e.g.,  2514 . The pay network server may issue the generated transaction data requests, e.g.,  2515   a - c , to the other pay network servers, e.g.,  2505   b - d . The other pay network servers may query, e.g.,  2517   a - c , their pay network database, e.g.,  2507   a - d , for transaction data falling within the scope of the transaction data requests. In response to the transaction data queries, the pay network databases may provide transaction data, e.g.,  2518   a - c , to the other pay network servers. The other pay network servers may return the transaction data obtained from the pay network databases, e.g.,  2519   a - c , to the pay network server making the transaction data requests, e.g.,  2505   a . The pay network server, e.g.,  2505   a , may store the aggregated transaction data, e.g.,  2520 , in an aggregated transactions database, e.g.,  2510   a.    
       FIG. 26  shows a logic flow diagram illustrating example aspects of aggregating card-based transaction data in some embodiments of the UEP, e.g., a Transaction Data Aggregation (“TDA”) component  2600 . In some implementations, a pay network server may obtain a trigger to aggregate transaction data, e.g.,  2601 . For example, the server may be configured to initiate transaction data aggregation on a regular, periodic, basis (e.g., hourly, daily, weekly, monthly, quarterly, semi-annually, annually, etc.). As another example, the server may be configured to initiate transaction data aggregation on obtaining information that the U.S. Government (e.g., Department of Commerce, Office of Management and Budget, etc) has released new statistical data related to the U.S. business economy. As another example, the server may be configured to initiate transaction data aggregation on-demand, upon obtaining a user investment strategy analysis request for processing. The pay network server may determine a scope of data aggregation required to perform the analysis, e.g.,  2602 . For example, the scope of data aggregation may be pre-determined. As another example, the scope of data aggregation may be determined based on a received user investment strategy analysis request. The pay network server may initiate data aggregation based on the determined scope. The pay network server may generate a query for addresses of server storing transaction data within the determined scope, e.g.,  2603 . The pay network server may query a database for addresses of pay network servers that may have stored transaction data within the determined scope of the data aggregation. The database may provide, e.g.,  2604 , a list of server addresses in response to the pay network server&#39;s query. Based on the list of server addresses, the pay network server may generate transaction data requests, e.g.,  2605 . The pay network server may issue the generated transaction data requests to the other pay network servers. The other pay network servers may obtain and parse the transaction data requests, e.g.,  2606 . Based on parsing the data requests, the other pay network servers may generate transaction data queries, e.g.,  2607 , and provide the transaction data queries to their pay network databases. In response to the transaction data queries, the pay network databases may provide transaction data, e.g.,  2608 , to the other pay network servers. The other pay network servers may return, e.g.,  2609 , the transaction data obtained from the pay network databases to the pay network server making the transaction data requests. The pay network server may generate aggregated transaction data records from the transaction data received from the other pay network servers, e.g.,  2610 , and store the aggregated transaction data in a database, e.g.,  2611 . 
       FIG. 27  shows a data flow diagram illustrating an example social data aggregation procedure in some embodiments of the UEP. In some implementations, the pay network server may obtain a trigger to perform a social data search. For example, the pay network server may periodically perform an update of its aggregated social database, e.g.,  2710 , with new information available from a variety of sources, such as the social networking services operating on the Internet. As another example, a request for on-demand social data update may be obtained as a result of a user wishing to enroll in a service, for which the pay network server may facilitate data entry by providing an automated web form filling system using information about the user obtained from the social data update. In some implementations, the pay network server may parse the trigger to extract keywords using which to perform an aggregated social data update. The pay network server may generate a query for application programming interface (API) templates for various social networking services (e.g., Facebook®, Twitter™, etc.) from which to collect social data for aggregation. The pay network server may query, e.g.,  2712 , a pay network database, e.g.,  2707 , for social network API templates for the social networking services. For example, the pay network server may utilize PHP/SQL commands similar to the examples provided above. The database may provide, e.g.,  2713 , a list of API templates in response. Based on the list of API templates, the pay network server may generate social data requests, e.g.,  2714 . The pay network server may issue the generated social data requests, e.g.,  2715   a - c , to the social network servers, e.g.,  2701   a - c . For example, the pay network server may issue PHP commands to request the social network servers for social data. An example listing of commands to issue social data requests  2715   a - c , substantially in the form of PHP commands, is provided below:

     In some embodiments, the social network servers may query, e.g.,  2717   a - c , their databases, e.g.,  2702   a - c , for social data results falling within the scope of the social keywords. In response to the queries, the databases may provide social data, e.g.,  2718   a - c , to the search engine servers. The social network servers may return the social data obtained from the databases, e.g.,  2719   a - c , to the pay network server making the social data requests. An example listing of social data  2719   a - c , substantially in the form of JavaScript Object Notation (JSON)-formatted data, is provided below:

     In some embodiments, the pay network server may store the aggregated search results, e.g.,  2720 , in an aggregated search database, e.g.,  2710 . 
       FIG. 28  shows a logic flow diagram illustrating example aspects of aggregating social data in some embodiments of the UEP, e.g., a Social Data Aggregation (“SDA”) component  2800 . In some implementations, the pay network server may obtain a trigger to perform a social search, e.g.,  2801 . For example, the pay network server may periodically perform an update of its aggregated social database with new information available from a variety of sources, such as the Internet. As another example, a request for on-demand social data update may be obtained as a result of a user wishing to enroll in a service, for which the pay network server may facilitate data entry by providing an automated web form filling system using information about the user obtained from the social data update. In some implementations, the pay network server may parse the trigger, e.g.,  2802 , to extract keywords and/or user ID(s) using which to perform an aggregated search for social data. The pay network server may determine the social networking services to search, e.g.,  2803 , using the extracted keywords and/or user ID(s). Then, the pay network server may generate a query for application programming interface (API) templates for the various social networking services (e.g., Facebook®, Twitter™, etc.) from which to collect social data for aggregation, e.g.,  2804 . The pay network server may query, e.g.,  2805 , a pay network database for search API templates for the social networking services. For example, the pay network server may utilize PHP/SQL commands similar to the examples provided above. The database may provide, e.g.,  2805 , a list of API templates in response. Based on the list of API templates, the pay network server may generate social data requests, e.g.,  2806 . The pay network server may issue the generated social data requests to the social networking services. The social network servers may parse the obtained search results(s), e.g.,  2807 , and query, e.g.,  2808 , their databases for social data falling within the scope of the search keywords. In response to the social data queries, the databases may provide social data, e.g.,  2809 , to the social networking servers. The social networking servers may return the social data obtained from the databases, e.g.,  2810 , to the pay network server making the social data requests. The pay network server may generate, e.g.,  2811 , and store the aggregated social data, e.g.,  2812 , in an aggregated social database. 
       FIG. 29  shows a data flow diagram illustrating an example procedure for enrollment in value-add services in some embodiments of the UEP. In some implementations, a user, e.g.,  2901 , may desire to enroll in a value-added service. Let us consider an example wherein the user desires to enroll in social network authenticated purchase payment as a value-added service. It is to be understood that any other value-added service may take the place of the below-described value-added service. The user may communicate with a pay network server, e.g.,  2903 , via a client such as, but not limited to: a personal computer, mobile device, television, point-of-sale terminal, kiosk, ATM, and/or the like (e.g.,  2902 ). For example, the user may provide user input, e.g., enroll input  2911 , into the client indicating the user&#39;s desire to enroll in social network authenticated purchase payment. In various implementations, the user input may include, but not be limited to: a single tap (e.g., a one-tap mobile app purchasing embodiment) of a touchscreen interface, keyboard entry, card swipe, activating a RFID/NFC enabled hardware device (e.g., electronic card having multiple accounts, smartphone, tablet, etc.) within the user device, mouse clicks, depressing buttons on a joystick/game console, voice commands, single/multi-touch gestures on a touch-sensitive interface, touching user interface elements on a touch-sensitive display, and/or the like. For example, the user may swipe a payment card at the client  2902 . In some implementations, the client may obtain track 1 data from the user&#39;s card as enroll input  2911  (e.g., credit card, debit card, prepaid card, charge card, etc.), such as the example track 1 data provided below:

     In some implementations, using the user&#39;s input, the client may generate an enrollment request, e.g.,  2912 , and provide the enrollment request, e.g.,  2913 , to the pay network server. For example, the client may provide a (Secure) Hypertext Transfer Protocol (“HTTP(S)”) POST message including data formatted according to the eXtensible Markup Language (“XML”). Below is an example HTTP(S) POST message including an XML-formatted enrollment request for the pay network server:

     In some implementations, the pay network server may obtain the enrollment request from the client, and extract the user&#39;s payment detail (e.g., XML data) from the enrollment request. For example, the pay network server may utilize a parser such as the example parsers described below in the discussion with reference to  FIG. 61 . In some implementations, the pay network server may query, e.g.,  2914 , a pay network database, e.g.,  2904 , to obtain a social network request template, e.g.,  2915 , to process the enrollment request. The social network request template may include instructions, data, login URL, login API call template and/or the like for facilitating social network authentication. For example, the database may be a relational database responsive to Structured Query Language (“SQL”) commands. The merchant server may execute a hypertext preprocessor (“PHP”) script including SQL commands to query the database for product data. An example PHP/SQL command listing, illustrating substantive aspects of querying the database, e.g.,  2914 - 2915 , is provided below:

     In some implementations, the pay network server may provide payment information extracted from the card authorization request to the social network server as part of a social network authentication enrollment request, e.g.,  2917 . For example, the pay network server may provide a HTTP(S) POST message to the social network server, similar to the example below:

     In some implementations, the social network server may provide a social network login request, e.g.,  2918 , to the client. For example, the social network server may provide a HTML input form to the client. The client may display, e.g.,  2919 , the login form for the user. In some implementations, the user may provide login input into the client, e.g.,  2920 , and the client may generate a social network login response, e.g.,  2921 , for the social network server. In some implementations, the social network server may authenticate the login credentials of the user, and access payment account information of the user stored within the social network, e.g., in a social network database. Upon authentication, the social network server may generate an authentication data record for the user, e.g.,  2922 , and provide an enrollment notification, e.g.,  2924 , to the pay network server. For example, the social network server may provide a HTTP(S) POST message similar to the example below:

     Upon receiving notification of enrollment from the social network server, the pay network server may generate, e.g.,  2925 , a user enrollment data record, and store the enrollment data record in a pay network database, e.g.,  2926 , to complete enrollment. In some implementations, the enrollment data record may include the information from the enrollment notification  2924 . 
       FIG. 30  shows a logic flow diagram illustrating example aspects of enrollment in a value-added service in some embodiments of the UEP, e.g., a Value-Add Service Enrollment (“VASE”) component  3000 . In some implementations, a user, e.g.,  2901 , may desire to enroll in a value-added service. Let us consider an example wherein the user desires to enroll in social network authenticated purchase payment as a value-added service. It is to be understood that any other value-added service may take the place of the below-described value-added service. The user may communicate with a pay network server via a client. For example, the user may provide user input, e.g.,  3001 , into the client indicating the user&#39;s desire to enroll in social network authenticated purchase payment. In various implementations, the user input may include, but not be limited to: a single tap (e.g., a one-tap mobile app purchasing embodiment) of a touchscreen interface, keyboard entry, card swipe, activating a RFID/NFC enabled hardware device (e.g., electronic card having multiple accounts, smartphone, tablet, etc.) within the user device, mouse clicks, depressing buttons on a joystick/game console, voice commands, single/multi-touch gestures on a touch-sensitive interface, touching user interface elements on a touch-sensitive display, and/or the like. In some implementations, using the user&#39;s input, the client may generate an enrollment request, e.g.,  3002 , and provide the enrollment request to the pay network server. In some implementations, the SNPA may provide an enrollment button that may take the user to an enrollment webpage where account info may be entered into web form fields. In some implementations, the pay network server may obtain the enrollment request from the client, and extract the user&#39;s payment detail from the enrollment request. For example, the pay network server may utilize a parser such as the example parsers described below in the discussion with reference to  FIG. 61 . In some implementations, the pay network server may query, e.g.,  3004 , a pay network database to obtain a social network request template, e.g.,  3005 , to process the enrollment request. The social network request template may include instructions, data, login URL, login API call template and/or the like for facilitating social network authentication. In some implementations, the pay network server may provide payment information extracted from the card authorization request to the social network server as part of a social network authentication enrollment request, e.g.,  3006 . In some implementations, the social network server may provide a social network login request, e.g.,  3007 , to the client. For example, the social network server may provide a HTML input form to the client. The client may display, e.g.,  3008 , the login form for the user. In some implementations, the user may provide login input into the client, e.g.,  3009 , and the client may generate a social network login response for the social network server. In some implementations, the social network server may authenticate the login credentials of the user, and access payment account information of the user stored within the social network, e.g., in a social network database. Upon authentication, the social network server may generate an authentication data record for the user, e.g.,  3011 , and provide an enrollment notification to the pay network server, e.g.,  3013 . Upon receiving notification of enrollment from the social network server, the pay network server may generate, e.g.,  3014 , a user enrollment data record, and store the enrollment data record in a pay network database, e.g.,  3015 , to complete enrollment. The pay network server may provide an enrollment confirmation, and provide the enrollment confirmation to the client, which may display, e.g.,  3017 , the confirmation for the user. 
       FIGS. 31A-B  show flow diagrams illustrating example aspects of normalizing aggregated search, enrolled, service usage, transaction and/or other aggregated data into a standardized data format in some embodiments of the UEP, e.g., a Aggregated Data Record Normalization (“ADRN”) component  3100 . With reference to  FIG. 31A , in some implementations, a pay network server (“server”) may attempt to convert any aggregated data records stored in an aggregated records database it has access to in a normalized data format. For example, the database may have a transaction data record template with predetermined, standard fields that may store data in pre-defined formats (e.g., long integer/double float/4 digits of precision, etc.) in a pre-determined data structure. A sample XML transaction data record template is provided below:

     In some implementations, the server may query a database for a normalized data record template, e.g.,  3101 . The server may parse the normalized data record template, e.g.,  3102 . Based on parsing the normalized data record template, the server may determine the data fields included in the normalized data record template, and the format of the data stored in the fields of the data record template, e.g.,  3103 . The server may obtain transaction data records for normalization. The server may query a database, e.g.,  3104 , for non-normalized records. For example, the server may issue PHP/SQL commands to retrieve records that do not have the ‘norm_flag’ field from the example template above, or those where the value of the ‘norm_flag’ field is ‘false’. Upon obtaining the non-normalized transaction data records, the server may select one of the non-normalized transaction data records, e.g.,  3105 . The server may parse the non-normalized transaction data record, e.g.,  3106 , and determine the fields present in the non-normalized transaction data record, e.g.,  3107 . For example, the server may utilize a procedure similar to one described below with reference to  FIG. 32 . The server may compare the fields from the non-normalized transaction data record with the fields extracted from the normalized transaction data record template. For example, the server may determine whether the field identifiers of fields in the non-normalized transaction data record match those of the normalized transaction data record template, (e.g., via a dictionary, thesaurus, etc.), are identical, are synonymous, are related, and/or the like. Based on the comparison, the server may generate a 1:1 mapping between fields of the non-normalized transaction data record match those of the normalized transaction data record template, e.g.,  3109 . The server may generate a copy of the normalized transaction data record template, e.g.,  3110 , and populate the fields of the template using values from the non-normalized transaction data record, e.g.,  3111 . The server may also change the value of the ‘norm_flag’ field to ‘true’ in the example above. The server may store the populated record in a database (for example, replacing the original version), e.g.,  3112 . The server may repeat the above procedure for each non-normalized transaction data record (see e.g.,  3113 ), until all the non-normalized transaction data records have been normalized. 
     With reference to  FIG. 31B , in some embodiments, the server may utilize metadata (e.g., easily configurable data) to drive an analytics and rule engine that may convert any structured data into a standardized XML format (“encryptmatics” XML). The encryptmatics XML may then be processed by an encryptmatics engine that is capable of parsing, transforming and analyzing data to generate decisions based on the results of the analysis. Accordingly, in some embodiments, the server may implement a metadata-based interpretation engine that parses structured data, including, but not limited to: web content (see e.g.,  3121 ), graph databases (see e.g.,  3122 ), micro blogs, images or software code (see e.g.,  3124 ), and converts the structured data into commands in the encryptmatics XML file format. For example, the structured data may include, without limitation, software code, images, free text, relational database queries, graph queries, sensory inputs (see e.g.,  3123 ,  3125 ), and/or the like. A metadata based interpretation engine, e.g.,  3126 , may populate a data/command object, e.g.,  3127 , based on a given record using configurable metadata, e.g.,  3128 . The configurable metadata may define an action for a given glyph or keyword contained within a data record. The engine may then process the object to export its data structure as a collection of encryptmatics vaults in a standard encryptmatics XML file format, e.g.,  3129 . The encryptmatics XML file may then be processed to provide various features by an encryptmatics engine, e.g.,  3130 . 
     In some embodiments, the server may obtain the structured data, and perform a standardization routine using the structured data as input (e.g., including script commands, for illustration). For example, the server may remove extra line breaks, spaces, tab spaces, etc. from the structured data, e.g.  3131 . The server may determine and load a metadata library, e.g.,  3132 , using which the server may parse subroutines or functions within the script, based on the metadata, e.g.,  3133 - 3134 . In some embodiments, the server may pre-parse conditional statements based on the metadata, e.g.,  3135 - 3136 . The server may also parse data  3137  to populate a data/command object based on the metadata and prior parsing, e.g.,  3138 . Upon finalizing the data/command object, the server may export  3139  the data/command object as XML in standardized encryptmatics format. 
       FIG. 32  shows a logic flow diagram illustrating example aspects of recognizing data fields in normalized aggregated data records in some embodiments of the UEP, e.g., a Data Field Recognition (“DFR”) component  3200 . In some implementations, a server may recognize the type of data fields included in a data record, e.g, date, address, zipcode, name, user ID, email address, payment account number (PAN), CVV2 numbers, and/or the like. The server may select an unprocessed data record for processing, e.g.,  3201 . The server may parse the data record rule, and extract data fields from the data record, e.g.,  3202 . The server may query a database for data field templates, e.g.,  3203 . For example, the server may compare the format of the fields from the data record to the data record templates to identify a match between one of the data field templates and each field within the data record, thus identifying the type of each field within the data record. The server may thus select an extracted data field from the data record, e.g.,  3204 . The server may select a data field template for comparison with the selected data field, e.g.,  3205 , and compare the data field template with the selected data field, e.g.,  3206 , to determine whether format of extracted data field matches format of data field template, e.g.,  3207 . If the format of the selected extracted data field matches the format of the data field template, e.g.,  3208 , option “Yes,” the server may assign the type of data field template to the selected data field, e.g.,  3209 . If the format of the extracted data field does not match the format of the data field template, e.g.,  3208 , option “No,” the server may try another data field template until no more data field templates are available for comparison, see e.g.,  3210 . If no match is found, the server may assign “unknown” string as the type of the data field, e.g.,  3211 . The server may store the updated data record in the database, e.g.,  3212 . The server may perform such data field recognition for each data field in the data record (and also for each data record in the database), see e.g.,  3213 . 
       FIG. 33  shows a logic flow diagram illustrating example aspects of classifying entity types in some embodiments of the UEP, e.g., an Entity Type Classification (“ETC”) component  3300 . In some implementations, a server may apply one or more classification labels to each of the data records. For example, the server may classify the data records according to entity type, according to criteria such as, but not limited to: geo-political area, number of items purchased, and/or the like. The server may obtain transactions from a database that are unclassified, e.g.,  3301 , and obtain rules and labels for classifying the records, e.g.,  3302 . For example, the database may store classification rules, such as the exemplary illustrative XML-encoded classification rule provided below: 
     
       
         
           
               
               
             
               
                   
                   
               
             
            
               
                   
                 &lt;rule&gt; 
               
            
           
           
               
               
            
               
                   
                 &lt;id&gt;PURCHASE_44_45&lt;/id&gt; 
               
               
                   
                 &lt;name&gt;Number of purchasers&lt;/name&gt; 
               
               
                   
                 &lt;inputs&gt;num_purchasers&lt;/inputs&gt; 
               
               
                   
                 &lt;operations&gt; 
               
            
           
           
               
               
            
               
                   
                 &lt;1&gt;label = ‘null’&lt;/1&gt; 
               
               
                   
                 &lt;2&gt;IF (num_purchasers &gt; 1) label = ‘household’&lt;/2&gt; 
               
            
           
           
               
               
            
               
                   
                 &lt;/operations&gt; 
               
               
                   
                 &lt;outputs&gt;label&lt;/outputs&gt; 
               
            
           
           
               
               
            
               
                   
                 &lt;/rule&gt; 
               
               
                   
                   
               
            
           
         
       
     
     The server may select an unclassified data record for processing, e.g.,  3303 . The server may also select a classification rule for processing the unclassified data record, e.g.,  3304 . The server may parse the classification rule, and determine the inputs required for the rule, e.g.,  3305 . Based on parsing the classification rule, the server may parse the normalized data record template, e.g.,  3306 , and extract the values for the fields required to be provided as inputs to the classification rule. The server may parse the classification rule, and extract the operations to be performed on the inputs provided for the rule processing, e.g.,  3307 . Upon determining the operations to be performed, the server may perform the rule-specified operations on the inputs provided for the classification rule, e.g.,  3308 . In some implementations, the rule may provide threshold values. For example, the rule may specify that if the number of products in the transaction, total value of the transaction, average luxury rating of the products sold in the transaction, etc. may need to cross a threshold in order for the label(s) associated with the rule to be applied to the transaction data record. The server may parse the classification rule to extract any threshold values required for the rule to apply, e.g.,  3309 . The server may compare the computed values with the rule thresholds, e.g.,  3310 . If the rule threshold(s) is crossed, e.g.,  3311 , option “Yes,” the server may apply one or more labels to the transaction data record as specified by the classification rule, e.g.,  3312 . For example, the server may apply a classification rule to an individual product within the transaction, and/or to the transaction as a whole. In some implementations, the server may process the transaction data record using each rule (see, e.g.,  3313 ). Once all classification rules have been processed for the transaction record, e.g.,  3313 , option “No,” the server may store the transaction data record in a database, e.g.,  3314 . The server may perform such processing for each transaction data record until all transaction data records have been classified (see, e.g.,  3315 ). 
       FIG. 34  shows a logic flow diagram illustrating example aspects of identifying cross-entity correlation in some embodiments of the UEP, e.g., a Cross-Entity Correlation (“CEC”) component  3400 . In some implementations, a server may recognize that two entities in the UEP share common or related data fields, e.g, date, address, zipcode, name, user ID, email address, payment account number (PAN), CVV2 numbers, and/or the like, and thus identify the entities as being correlated. The server may select a data record for cross-entity correlation, e.g.,  3401 . The server may parse the data record rule, and extract data fields from the data record, e.g.,  3402 - 3403 . The server may select an extracted data field from the data record, e.g.,  3404 , and query a database for other data records having the same data field as the extracted data field, e.g.,  3405 . From the list of retrieved data records from the database query, the server may select a record for further analysis. The server may identify, e.g.,  3407 , an entity associated with the retrieved data record, e.g., using the ETC  3300  component discussed above in the description with reference to  FIG. 33 . The server may add a data field to the data record obtained for cross-entity correlation specifying the correlation to the retrieved selected data record, e.g.,  3408 . In some embodiments, the server may utilize each data field in the data record obtained for cross-entity correlation to identify correlated entities, see e.g.,  3409 . The server may add, once complete, a “correlated” flag to the data record obtained for cross-entity correlation, e.g.,  3410 , e.g., along with as timestamp specifying the time at which the cross-entity correlation was performed. For example, such a timestamp may be used to determine at a later time whether the data record should be processed again for cross-entity correlation. The server may store the updated data record in a database. 
       FIG. 35  shows a logic flow diagram illustrating example aspects of associating attributes to entities in some embodiments of the UEP, e.g., an Entity Attribute Association (“EAA”) component  3500 . In some implementations, a server may associate attributes to an entity, e.g., if the entity id a person, the server may identify a demographic (e.g., male/female), a spend character, a purchase preferences list, a merchants preference list, and/or the like, based on field values of data fields in data records that are related to the entity. In some implementations, a server may obtain a data record for entity attribute association, e.g.,  3501 . The server may parse the data record rule, and extract data fields from the data record, e.g.,  3502 - 3503 . The server may select an extracted data field from the data record, e.g.,  3504 , and identify a field value for the selected extracted data field from the data record, e.g.,  3505 . The server may query a database for demographic data, behavioral data, and/or the like, e.g.,  3506 , using the field value and field type. In response, the database may provide a list of potential attributes, as well as a confidence level in those attribute associations to the entity, see e.g.,  3507 . The server may add data fields to the data record obtained for entity attribute association specifying the potentially associated attributes and their associated confidence levels, e.g.,  3508 . In some embodiments, the server may utilize each data field in the data record obtained for cross-entity correlation to identify correlated entities, see e.g.,  3509 . The server may store the updated data record in a database, e.g.,  3510 . 
       FIG. 36  shows a logic flow diagram illustrating example aspects of updating entity profile-graphs in some embodiments of the UEP, e.g., an Entity Profile-Graph Updating (“EPGU”) component  3600 . In some implementations, a server may generate/update a profile for an entity whose data is stored within the UEP. The server may obtain an entity profile record for updating, e.g.,  3601 . The server may parse the entity profile record, and extract an entity identifier data field from the data record, e.g.,  3602 . The server may query a database for other data records that are related to the same entity, e.g.,  3603 , using the value for the entity identifier data field. In response, the database may provide a list of other data records for further processing. The server may select one of the other data records to update the entity profile record, e.g.,  3604 . The server may parse the data record, and extract all correlations, associations, and new data from the other record, e.g.,  3605 . The server may compare the correlations, attributes, associations, etc., from the other data record with the correlations, associations and attributes from the entity profile. Based on this comparison, the server may identify any new correlations, associations, etc., and generate an updated entity profile record using the new correlations, associations; flag new correlations, associations for further processing, e.g.,  3607 . In some embodiments, the server may utilize each data record obtained for updating the entity profile record as well as its social graph (e.g., as given by the correlations and associations for the entity), see e.g.,  3609 . The server may store the updated entity profile record in a database, e.g.,  3608 . 
       FIG. 37  shows a logic flow diagram illustrating example aspects of generating search terms for profile-graph updating in some embodiments of the UEP, e.g., a Search Term Generation (“STG”) component  3700 . In some implementations, a server may generate/update a profile for an entity whose data is stored within the UEP, by performing search for new data, e.g., across the Internet and social networking services. The server may obtain an entity profile record for updating, e.g.,  3701 . The server may parse the entity profile record, and extract data field types and field values from the entity profile record, e.g.,  3702 . The server may query a database for other data records that are related to the same entity, e.g.,  3703 , using the values for the extracted data fields. In response, the database may provide a list of other data records for further processing. The server may parse the data records, and extract all correlations, associations, and data from the data records, e.g.,  3704 . The server may aggregate all the data values from all the records and the entity profile record, e.g.,  3705 . Based on this, the server may return the aggregated data values as search terms to trigger search processes (see e.g.,  FIG. 20, 2001-2005 ), e.g.,  3706 . 
     User Behavior-Based Recommendation 
       FIG. 38  shows a logic flow diagram illustrating example aspects of analyzing a user&#39;s behavior based on aggregated purchase transaction data in some embodiments of the UEP, e.g., a User Behavior Analysis (“UBA”) component  3800 . In some implementations, a pay network server (“server”) may obtain a user ID of a user for whom the server is required to generate user behavioral patterns, e.g.,  3801 . The server may query a database, e.g., a pay network database, for aggregated card transaction data records of the user, e.g.,  3802 . The server may also query, e.g.,  3803 , the pay network database for all possible field value that can be taken by each of the field values (e.g., AM/PM, zipcode, merchant_ID, merchant_name, transaction cost brackets, etc.). Using the field values of all the fields in the transaction data records, the server may generate field value pairs, for performing a correlation analysis on the field value pairs, e.g.,  3804 . An example field value pair is: ‘time’ is ‘AM’ and ‘merchant’ is ‘Walmart’. The server may then generate probability estimates for each field value pair occurring in the aggregated transaction data records. For example, the server may select a field value pair, e.g.,  3805 . The server may determine the number of records within the aggregated transaction data records where the field value pair occurs, e.g.,  3806 . The server may then calculate a probability quotient for the field value pair by dividing the number determined for the occurrences of the field value pair by the total number of aggregate transaction data records, e.g.,  3807 . The server may also assign a confidence level for the probability quotient based on the sample size, e.g., total number of records in the aggregated transaction data records, e.g.,  3808 . The server may generate and store an XML snippet, including the field value pair, the probability quotient, and the confidence level associated with the probability quotient, e.g.,  3809 . The server may perform such a computation for each field value pair (see  3810 ) generated in  3804 . 
       FIG. 39  shows a logic flow diagram illustrating example aspects of generating recommendations for a user based on the user&#39;s prior aggregate purchase transaction behavior in some embodiments of the UEP, e.g., a User Behavior-Based Offer Recommendations (“UBOR”) component  3900 . In some implementations, a pay network server (“server”) may obtain a user ID of a user for whom the server is required to generate offer recommendations, e.g.,  3901 . The server may obtain a list of products included in a card authorization request for processing the purchase transaction for the user, e.g.,  3902 . The server may also query a database for pre-generated pair-wise correlations of various user transaction-related variables, e.g.,  3902   b , such as those generated by the UBA  3800  component described above with reference to  FIG. 38 . The server may select a product from the list of products included in the card authorization request, e.g.,  3903 . The server may identify all field pair-correlation values where the selected product was the independent field into the field-pair correlation, e.g.,  3904 . The server may, e.g.,  3905 , from among the identified field-pair values, identify the product that was the dependent field value for the field value pair having the highest probability quotient (e.g., product most likely to be bought together with the product selected from the product list included in the card authorization request). The server may store the identified product, along with its associated prediction confidence level, in a queue of products for recommendation, e.g.,  3906 . The server may perform the analysis for each product included in the product list from the card authorization request, see e.g.,  3907 . 
     In some implementations, upon completing such an analysis for all the products in the card authorization request, the server may sort the queue according to their associated probability quotient and prediction confidence level, e.g.,  3908 . For example, if the prediction confidence level of a product is higher than a threshold, then it may be retained in the queue, but not if the prediction confidence level is lower than the threshold. Also, the retained products may be sorted in descending order of their associated probability quotients. In some implementations, the server may eliminate any duplicated products form the queue, e.g.,  3909 . The server may return the sorted queue of products for product offer recommendation, e.g.,  3910 . 
     Social Payment Platform 
       FIG. 40  shows a block diagram illustrating example aspects of payment transactions via social networks in some embodiments of the UEP. In some embodiments, the UEP may facilitate per-2-person transfers  4010  of money via social networks. For example, a user (user1  4011 ) may wish to provide funds (dollars, rewards, points, miles, etc.  4014 ) to another user (user2  4016 ). The user may utilize a virtual wallet to provide a source of funds. In some embodiments, the user may utilize a device  4012  (such as a smartphone, mobile device, laptop computer, desktop computer, and/or the like) to send a social post message via the social network  4015 . In some embodiments, the social post message may include information on an amount of funds to be transferred and an identity of another user to whom the funds should be transferred. The UEP may intercept the message before it is sent to the social networking service, or it may obtain the message from the social networking service. Using the social post message, the UEP may resolve the identities of a payor and payee in the transaction. The UEP may identify accounts of the payor and payee to/from which funds need be credited or debited, and an amount of credit/debit to apply to each of the accounts. The UEP may, on the basis of resolving this information, execute a transaction to transfer funds from the payor to the payee. For example, the UEP may allow a payor, by sending a tweet on Twitter™ such as “$25 @jfdoe #ackpls” to transfer funds to a payee (user ID jfdoe), and request an acknowledgement from UEP of receipt of funds. In another example, the UEP may allow a potential payee to request funds from another user by sending a tweet on Twitter™ such as “@johnq, you owe me 50000 Visa rewards points #id1234”; the UEP may automatically provide an alert within a virtual wallet application of the user with user ID johnq to provide the funds to the potential payee user. The user johnq may respond by sending a tweet in response, referencing the id (#id1234), such as “50000 vpts @jfdoe #id1234”; the UEP may transfer the funds and recognize transaction request #id1234 as being fulfilled. In some embodiments, the UEP may generate transaction/request ID numbers for the users to prevent coinciding transaction/request ID numbers for different transaction/requests. 
     In some embodiments, the UEP may utilize one or more social networking services (e.g., Facebook®, Twitter™, MySpace™, etc.). In some embodiments, the UEP may allow users across different social networks to transact with each other. For example, a user may make a request for payment on one social network. As an example, a Twitter™ user may tweet “@johnq@facebook.com, you owe me 500 vpts #ID7890”). The UEP may provide an alert to the user with ID johnq@facebook.com either via the other social networking or via the user&#39;s virtual wallet. In response, the payee may social post to Facebook® a message “@jfdoe: here&#39;s your 500 vpts #ID7890”, and the UEP may facilitate the payment transaction and provide a receipt/acknowledgment to the two users on their respective social networks or virtual wallets. 
     In some embodiments, the UEP may facilitate transfers of funds to more than one payee by a payor via a single social post message. In some embodiments, the UEP may facilitate use of more than one source of funds of a payee to fund payment of funds to one or more payors via a single post message. For example, the UEP may utilize default settings or customized rules, stored within a virtual wallet of a payor, to determine which funding sources to utilize to fund a payment transaction to one or more payees via a social post message. 
     In some implementations, the UEP may facilitate merchants to make offers of products and/or services to consumers via social networks  4020 . For example, a merchant  4026  may sign up to participate in the UEP. The UEP may aggregate transactions of a user, and determine any products or services that may relevant for offering to the user. The UEP may determine whether any participating merchants are available to provide the products or services for the users. If so, the UEP may provide social post messages via a social network  4025  on behalf of the merchants (or, alternatively, inform the merchants who may then send social post messages to the users) providing the offers  4024   a  to the user  4021 . An example of an offer to the followers of a merchant on may be “@amazon offers the new Kindle™ at only $149.99—click here to buy.” In such an example, the offer posted on the social networking site may have a link embedded (e.g., “here”) that users can click to make the purchase (which may be automatically performed with one-click if they are currently logged into their virtual wallet accounts  4023 ). Another example of a merchant offer may be “@amazon offers the new Kindle™ at only $149.99—reply with #offerID123456 to buy.” In such an example, the hash tag value serves as an identifier of the offer, which the users can reference when making their purchase via their social post messages (e.g., “buy from @amazon #offerID123456”). In some embodiments, merchants may provide two or more offers via a single social post message. In some embodiments, users may reference two or more offers in the same social post message. 
     In some implementations, users and/or merchants may utilize alternate messaging modes. For example, a user may be able to utilize electronic mail, SMS messages, phone calls, etc., to communicate with the UEP and the social networks. For example, a merchant may provide a social post message offer such as “@amazon offers the new Kindle™ at only $149.99—text #offerID123456 to buy”. When a user utilize a mobile phone to send a text message to redeem the offer, the UEP may utilize a user profile of the user store on the social networking service to identify an identifying attribute of the user&#39;s mobile phone (e.g., a phone number), using which the UEP may correlate the text message to a particular user. Thus, the UEP may be able to process a transaction with the merchant on behalf of the user, using user information from the user&#39;s virtual wallet. In some embodiments where a social network is incapable of handling a particular mode of communication, the UEP may serve as an intermediary translator to convert the message to a form that can be utilized by the social network. 
       FIG. 41  shows a data flow diagram illustrating an example social pay enrollment procedure in some embodiments of the UEP. In some embodiments, a user, e.g.,  4101 , may desire to enroll in UEP. The user may communicate with a social pay server, e.g.,  4103   a , via a client such as, but not limited to: a personal computer, mobile device, television, point-of-sale terminal, kiosk, ATM, and/or the like (e.g.,  4102 ). For example, the user may provide user input, e.g., social pay enrollment input  4111 , into the client indicating the user&#39;s desire to enroll in social network authenticated purchase payment. In various implementations, the user input may include, but not be limited to: a single tap (e.g., a one-tap mobile app purchasing embodiment) of a touchscreen interface, keyboard entry, card swipe, activating a RFID/NFC enabled hardware device (e.g., electronic card having multiple accounts, smartphone, tablet, etc.) within the user device, mouse clicks, depressing buttons on a joystick/game console, voice commands, single/multi-touch gestures on a touch-sensitive interface, touching user interface elements on a touch-sensitive display, and/or the like. 
     In some implementations, using the user&#39;s input, the client may generate a social pay enrollment request, e.g.,  4112 , and provide the enrollment request to the social pay server  4103   a . For example, the client may provide a (Secure) Hypertext Transfer Protocol (“HTTP(S)”) POST message including data formatted according to the eXtensible Markup Language (“XML”). Below is an example HTTP(S) POST message including an XML-formatted enrollment request for the social pay server: 
     
       
         
           
               
             
               
                   
               
             
            
               
                 POST /enroll.php HTTP/1.1

                 &lt;client_type&gt;smartphone&lt;/client_type&gt; 
               
               
                   
                 &lt;client_model&gt;HTC Hero&lt;/client_model&gt; 
               
               
                   
                 &lt;OS&gt;Android 2.2&lt;/OS&gt; 
               
               
                   
                 &lt;app_installed_flag&gt;true&lt;/app_installed_flag&gt; 
               
            
           
           
               
               
            
               
                   
                 &lt;/client_details&gt; 
               
            
           
           
               
            
               
                 &lt;/enrollment_request&gt; 
               
               
                   
               
            
           
         
       
     
     In some embodiments, the social pay server may obtain the enrollment request from the client, and extract the user&#39;s payment detail (e.g., XML data) from the enrollment request. For example, the social pay server may utilize a parser such as the example parsers described below in the discussion with reference to  FIG. 61 . In some implementations, the social pay server may query, e.g.,  4113 , a social pay database, e.g.,  4103   b , to obtain a social network request template, e.g.,  4114 , to process the enrollment request. The social network request template may include instructions, data, login URL, login API call template and/or the like for facilitating social network authentication. For example, the database may be a relational database responsive to Structured Query Language (“SQL”) commands. The merchant server may execute a hypertext preprocessor (“PHP”) script including SQL commands to query the database for product data. An example PHP/SQL command listing, illustrating substantive aspects of querying the database, e.g.,  4114 - 4115 , is provided below:

                 //create query 
               
               
                 $query = “SELECT template FROM EnrollTable WHERE network LIKE

                 $socialnet”; 
               
            
           
           
               
            
               
                 $result = mysql_query($query); // perform the search query

     In some implementations, the social pay server may provide information extracted from the social pay enrollment request to the social network server as part of a user authentication/social pay app enroll request, e.g.,  4115 . For example, the social pay server may provide a HTTP(S) POST message to the social network server, similar to the example below:

     In some implementations, the social network server may provide a social network login request, e.g.,  4116 , to the client. For example, the social network server may provide a HTML input form to the client. The client may display, e.g.,  4117 , the login form for the user. In some implementations, the user may provide login input into the client, e.g.,  4118 , and the client may generate a social network login response, e.g.,  4119 , for the social network server. In some implementations, the social network server may authenticate the login credentials of the user, and upon doing so, update the profile of the user to indicate the user&#39;s enrollment in the social pay system. For example, in a social networking service such as Facebook®, the social network server may provide permission to a social pay third-party developer app to access the user&#39;s information stored within the social network. In some embodiments, such enrollment may allow a virtual wallet application installed on a user device of to access the user&#39;s social profile information stored within the social network. Upon authentication, the social network server may generate an updated data record for the user, e.g.,  4120 , and provide an enrollment notification, e.g.,  4121 , to the social pay server. For example, the social network server may provide a HTTP(S) POST message similar to the example below: 
     
       
         
           
               
               
             
               
                   
                   
               
             
            
               
                   
                 POST /enrollnotification.php HTTP/1.1

                 &lt;/enroll_notification&gt; 
               
               
                   
                   
               
            
           
         
       
     
     Upon receiving notification of enrollment from the social network server, the social pay server may generate, e.g.,  4122 , a user enrollment data record, and store the enrollment data record in a social pay database, e.g.,  4123 , to complete enrollment. In some implementations, the enrollment data record may include the information from the enrollment notification  4121 . 
       FIG. 42  shows a logic flow diagram illustrating example aspects of social pay enrollment in some embodiments of the UEP, e.g., a Social Pay Enrollment (“SPE”) component  4200 . In some embodiments, a user may desire to enroll in UEP. The user may provide user input, e.g., social pay enrollment input  4201 , into the client indicating the user&#39;s desire to enroll in social network authenticated purchase payment. In some implementations, using the user&#39;s input, the client may generate a social pay enrollment request, e.g.,  4202 , and provide the enrollment request to the social pay server. In some embodiments, the social pay server may obtain the enrollment request from the client, and extract the user&#39;s payment detail (e.g., XML data) from the enrollment request. For example, the social pay server may utilize a parser such as the example parsers described below in the discussion with reference to  FIG. 61 . In some implementations, the social pay server may query, e.g.,  4203 , a social pay database to obtain a social network request template to process the enrollment request. The social network request template may include instructions, data, login URL, login API call template and/or the like for facilitating social network authentication. In some implementations, the social pay server may redirect the client to a social network server. In some implementations, the social pay server may provide information extracted from the social pay enrollment request to the social network server as part of a user authentication/social pay app enroll request, e.g.,  4205 . In some implementations, the social network server may provide a social network login request, e.g.,  4206 , to the client. For example, the social network server may provide a HTML input form to the client. The client may display, e.g.,  4207 , the login form for the user. In some implementations, the user may provide login input into the client, e.g.,  4208 , and the client may generate a social network login response, e.g.,  4209 , for the social network server. In some implementations, the social network server may authenticate the login credentials of the user, and upon doing so, update the profile of the user to indicate the user&#39;s enrollment in the social pay system. For example, in a social networking service such as Facebook®, the social network server may provide permission to a social pay third-party developer app to access the user&#39;s information stored within the social network. In some embodiments, such enrollment may allow a virtual wallet application installed on a user device of to access the user&#39;s social profile information stored within the social network. Upon authentication, the social network server may generate an updated data record for the user, e.g.,  4210 - 4211 , and provide an enrollment notification, e.g.,  4212  to the social pay server. Upon receiving notification of enrollment from the social network server, the social pay server may generate, e.g.,  4213 , a user enrollment data record, and store the enrollment data record in a social pay database, e.g.,  314 , to complete enrollment. In some implementations, the enrollment data record may include the information from the enrollment notification. 
       FIGS. 43A-C  show data flow diagrams illustrating an example social payment triggering procedure in some embodiments of the UEP. With reference to  FIG. 43A , in some embodiments, a user, e.g., user1  4301   a , may desire to provide or request funds from another (e.g., a user, a participating merchant, etc.). The user may communicate with a social network server, e.g.,  4303   a , via a client (client1  4302   a ) such as, but not limited to: a personal computer, mobile device, television, point-of-sale terminal, kiosk, ATM, and/or the like. For example, the user may provide social payment input  4311 , into the client indicating the user&#39;s desire to provide or request funds from another. In various embodiments, the user input may include, but not be limited to: a single tap (e.g., a one-tap mobile app purchasing embodiment) of a touchscreen interface, keyboard entry, card swipe, activating a RFID/NFC enabled hardware device (e.g., electronic card having multiple accounts, smartphone, tablet, etc.) within the user device, mouse clicks, depressing buttons on a joystick/game console, voice commands, single/multi-touch gestures on a touch-sensitive interface, touching user interface elements on a touch-sensitive display, and/or the like. In response, the client may provide a social message post request  4312  to the social network server. In some implementations, a virtual wallet application executing on the client may provide the user with an easy-to-use interface to generate and send the social message post request. In alternate implementations, the user may utilize other applications to provide the social message post request. For example, the client may provide a social message post request to the social network server as a HTTP(S) POST message including XML-formatted data. An example listing of a social message post request  4312 , substantially in the form of a HTTP(S) POST message including XML-formatted data, is provided below:

     In some embodiments, the social network server  4304   a  may query its social network database for a social graph of the user, e.g.,  4313 . For example, the social network server may issue PHP/SQL commands to query a database table (such as  FIG. 61 , Social Graph  6119   p ) for social graph data associated with the user. An example user social graph query  4313 , substantially in the form of PHP/SQL commands, is provided below:

                 LIKE ‘%’ $user_id”; 
               
               
                 $result = mysql_query($query); // perform the search query

     In some embodiments, the social network database may provide the requested social graph data in response, e.g.,  4314 . Using the social graph data, the social network server may generate message(s) as appropriate for the user and/or members of the user&#39;s social graph, e.g.,  4315 , and store the messages  4316  for the user and/or social graph members. 
     With reference to  FIG. 43B , in some embodiments, such posting of social messages may trigger UEP actions. For example, a social pay server  4303   a  may be triggered to scan the social data for pay commands. In embodiments where every social post message originates from the virtual wallet application of a user, the UEP may optionally obtain the pay commands from the virtual wallet applications, and skip scanning the social networks for pay commands associated with the user. In embodiments where a user is allowed to issue pay commands from any device (even those not linked to the user&#39;s virtual wallet), the UEP may periodically, or even continuously scan the social networks for pay commands, e.g.,  4321 . In embodiments where the UEP scans the social networks, the social pay server may query a social pay database for a profile of the user. For example, the social pay server may request a user ID and password for the social networks that the user provided to the social pay server during the enrollment phase (see, e.g.,  FIGS. 41-42 ). For example, the social pay server may issue PHP/SQL commands to query a database table (such as  FIG. 61 , Users  6119   a ) for user profile data. An example user profile data query  4322 , substantially in the form of PHP/SQL commands, is provided below:

     In some embodiments, the social pay server may process the user social data using the social pay rules to identify pay commands, pay requests, merchant offers, and/or like content of the user social data. In some embodiments, rules may be provided by the UEP to ensure the privacy and security of the user&#39;s social data and virtual wallet. As another example, the rules may include procedures to detect fraudulent transaction attempts, and request user verification before proceeding, or cancel the transaction request entirely. In some embodiments, the social pay server may utilize a wallet security and settings component, such as the example WSS  4500  component described further below in the discussion with reference to  FIGS. 45A-B . 
     With reference to  FIG. 43C , in some embodiments, the social pay server may optionally determine that, based on processing of the rules, user verification is needed to process a transaction indicated in a pay command. For example, if the rules processing indicated that there is a probability of the pay command being an attempt at a fraudulent transaction attempt, the social pay server may determine that the user must be contacted for payment verification before the transaction can be processed. In such scenarios, the social pay server may provide a pay command verification request  4333  to the client, which the client may display, e.g.,  4334 , to the user. For example, the social pay server may provide a pay command verification request to the client  4302   a  as a HTTP(S) POST message including XML-formatted data. An example listing of a pay command verification request  4333 , substantially in the form of a HTTP(S) POST message including XML-formatted data, is provided below:

     In some embodiments, the user may provide a verification input  4335  into the client, which may provide a pay command verification response to the social pay server. The social pay server may determine whether the payor verified payment, whether payee information available is sufficient to process the transaction, and/or the like. In scenarios where sufficient payee information is unavailable, the social pay server may optionally provide a social post message  4338  to a social networking service associated with the potential payee requesting the payee to enroll in social pay service (e.g., using the SPE  4200  component described above in the discussion with reference to  FIGS. 41-42 ), which the social network server may post  4339  for the payee. If all the requirements are met for processing the transaction, the social pay server may generate a unique transaction trigger associated with the triggering social post message, e.g.,  4337 , and store a transaction trigger ID, triggering social post message, etc., for recordkeeping or analytics purposes, e.g.,  4340 . The social pay server may provide the transaction trigger to trigger a purchase transaction  4341 , e.g., via a purchase transaction authorization such as the example PTA component described below in the discussion with reference to  FIG. 58 . 
       FIGS. 44A-C  show logic flow diagrams illustrating example aspects of social payment triggering in some embodiments of the UEP, e.g., a Social Payment Triggering (“SPT”) component  4400 . With reference to  FIG. 44A , in some embodiments, a user may desire to provide or request funds from another (e.g., a user, a participating merchant, etc.). The user may communicate with a social network server via a client. For example, the user may provide social payment input  4401 , into the client indicating the user&#39;s desire to provide or request funds from another. In response, the client may generate and provide a social message post request  4402  to the social network server. In some implementations, a virtual wallet application executing on the client may provide the user with an easy-to-use interface to generate and send the social message post request. In alternate implementations, the user may utilize other applications to provide the social message post request. In some embodiments, the social network server may query its social network database for a social graph of the user, e.g.,  4403 . In response, the social network database may provide the requested social graph data, e.g.,  4404 . Using the social graph data, the social network server may generate message(s) as appropriate for the user and/or members of the user&#39;s social graph, e.g.,  4405 , and store the messages  4406  for the user and/or social graph members. 
     With reference to  FIG. 44B , in some embodiments, such posting of social messages may trigger UEP actions. For example, a social pay server may be triggered to scan the social data for pay commands, e.g.,  4407 . In embodiments where every social post message originates from the virtual wallet application of a user, the UEP may optionally obtain the pay commands from the virtual wallet applications, and skip scanning the social networks for pay commands associated with the user. In embodiments where a user is allowed to issue pay commands from any device (even those not linked to the user&#39;s virtual wallet), the UEP may periodically, or even continuously scan the social networks for pay commands. In embodiments where the UEP scans the social networks, the social pay server may query a social pay database for a profile of the user,  4408 . For example, the social pay server may request a user ID and password for the social networks that the user provided to the social pay server during the enrollment phase (see, e.g.,  FIGS. 41-42 ). In response, the social pay database may provide the requested information, e.g.,  4409 . In some embodiments, the social pay server may generate provide a user social data request  4410  to the social network server. 
     In some embodiments, the social network server may extract a user ID from the user social data request, e.g.,  4411 . The social network server may query, e.g.,  4412 , it social network database to determine whether the user is enrolled in UEP with the social network (e.g., “did the user allow the UEP Facebook® app to access user data?”). In response, the social network database may provide user enrollment data relating to UEP. The social network server may determine whether the user is enrolled, and thus whether the social pay server is authorized to access the user social data,  4414 . If the social network server determines that the social pay server is not authorized,  4415 , option “No,” it may generate a service denial message,  4416 , and provide the message to the social pay server. If the social network server determines that the social pay server is authorized to access the user social data,  4415 , option “Yes,” the social network server may generate a user social data query  4417 , and provide it to the social network database. In response, the social network database may provide the user social data requested,  4418 . The social network server may provide the user social data  4419  to the social pay server. 
     In some embodiments, the social pay server may query the social pay database for social pay rules, e.g.,  4420 - 4421 . In some embodiments, the social pay server may process the user social data using the social pay rules to identify pay commands, pay requests, merchant offers, and/or like content of the user social data,  4422 . In some embodiments, rules may be provided by the UEP to ensure the privacy and security of the user&#39;s social data and virtual wallet. As another example, the rules may include procedures to detect fraudulent transaction attempts, and request user verification before proceeding, or cancel the transaction request entirely. In some embodiments, the social pay server may utilize a wallet security and settings component, such as the example WSS  4500  component described further below in the discussion with reference to  FIGS. 45A-B . 
     With reference to  FIG. 44C , in some embodiments, the social pay server may optionally determine that, based on processing of the rules, user verification is needed to process a transaction indicated in a pay command,  4423 , option “Yes.” For example, if the rules processing indicated that there is a probability of the pay command being an attempt at a fraudulent transaction attempt, the social pay server may determine that the user must be contacted for payment verification before the transaction can be processed. In such scenarios, the social pay server may provide a pay command verification request  4425  to the client, which the client may display, e.g.,  4426 , to the user. In some embodiments, the user may provide a verification input  4427  into the client, which may provide a pay command verification response to the social pay server,  4428 . The social pay server may determine whether the payor verified payment, whether payee information available is sufficient to process the transaction, and/or the like,  4429 . In scenarios where sufficient payee information is unavailable or the payor needs to be contacted for payment verification,  4430 , option “No,” the social pay server may optionally provide a social post message  4431  to a social networking service associated with the potential payee/payor requesting the payee to enroll in social pay service (e.g., using the SPE  4200  component described above in the discussion with reference to  FIGS. 41-42 ) or provide verification, which the social network server may post  4432 - 4433  for the payee. If all the requirements are met for processing the transaction,  4430 , option “Yes,” the social pay server may generate a unique transaction trigger associated with the triggering social post message, e.g.,  4434 , and may optionally store a transaction trigger ID, triggering social post message, etc., for recordkeeping or analytics purposes. The social pay server may provide the transaction trigger to trigger a purchase transaction, e.g., via a purchase transaction authorization component. 
       FIGS. 45A-B  show logic flow diagrams illustrating example aspects of implementing wallet security and settings in some embodiments of the UEP, e.g., a Something (“WSS”) component  4500 . In some embodiments, the social pay server may process the user social data using the social pay rules to identify pay commands, pay requests, merchant offers, and/or like content of the user social data. In some embodiments, rules may be provided by the UEP to ensure the privacy and security of the user&#39;s social data and virtual wallet. As another example, the rules may include procedures to detect fraudulent transaction attempts, and request user verification before proceeding, or cancel the transaction request entirely. 
     Accordingly, with reference to  FIG. 45A , in some embodiments, the UEP may obtain a trigger to process a user&#39;s social data (e.g., from  FIG. 44B , element  4431 ),  4501 . The UEP may obtain user and/or user social graph member social data, as well as pay command rules and templates (e.g., for identifying standard pay commands),  4502 . The UEP may parse the obtained user social data in preparation for rules processing,  4503 . For example, the UEP may utilize parsers such as the example parsers described below in the discussion with reference to  FIG. 61 . The UEP may select a pay command rule/template for processing. The UEP may search through the parsed user social data, e.g., in a sequential manner, for the selected pay command,  4512 , and determine whether the pay command is present in the user social data,  4513 . If the pay command is identified,  4514 , option “Yes,” the UEP may place the identified pay command string, an identification of the rule/template, the actual listing of the rule/template, and/or the like in a queue for further processing,  4515 . The UEP may perform such a procedure until the entirety of the user&#39;s social data has been searched through (see  4516 ). In some embodiments, the UEP may perform the above procedure for all available rules/templates, to identify all the pay command strings included in the user social data (see  4517 ). 
     In some embodiments, the UEP may process each pay command identified from the user social data,  4520 . For example, the UEP may select a pay command string from the queue and its associated template/identification rule,  4521 . Using the rule/template and pay command string, the UEP may determine whether the string represents a request for payment, or an order to pay,  4523 . If the pay command string represents a request for payment (e.g., “hey @jfdoe, you owe me 25 bucks #cashflowblues”),  4524 , option “Yes,” the UEP may determine whether the user for whom the WSS component is executing is the requested payor, or the payee,  4525 . If the user has been requested to pay,  4526 , option “Yes,” the UEP may add a payment reminder to the user wallet account,  4527 . Otherwise, the UEP may generate a user pay request record including the pay command details,  4528 , and store the pay request record in the user&#39;s wallet account for recordkeeping purposes or future analytics processing,  4529 . 
     With reference to  FIG. 45B , in some embodiments, the UEP may extract an identification of a payor and payee in the transaction,  4531 . The UEP may query a database for payee account data for payment processing,  4532 . If the payee data available is insufficient,  4533 , option “Yes,” the UEP may generate a social post message to the payee&#39;s social network account  4534 , requesting that the payee either enroll in the UEP (if not already), or provide additional information so that the UEP may process the transaction. The UEP may provide  4535  the social post message to the social networking service associated with the payee. If sufficient payee information is available,  4533 , option “No,” the UEP may query the payor&#39;s wallet account for security rules associated with utilizing the virtual wallet account,  4536 . The UEP may select a wallet security rule,  4537 , and process the security rule using the pay command string as input data,  4538 . Based on the processing, the UEP may determine whether the pay command passes the security rule, or instead poses a security risk to the user wallet. If the security rule is not passed,  4540 , option “No,” the UEP may determine whether verification from the user can salvage the pay command string,  4541 . If the UEP determines that the risk is too great, the UEP may directly terminate the transaction and remove the pay command string from the processing queue. Otherwise ( 4541 , option “Yes”), the UEP may generate a pay command verification request for the user,  4542 , and provide the pay command verification request as an output of the component,  4543 . If all security rules are passed for the pay command string,  4544 , option “No,” the UEP may generate a transaction trigger with a trigger ID (such as a card authorization request), and provide the transaction trigger for payment processing. 
       FIG. 46  shows a data flow diagram illustrating an example social merchant consumer bridging procedure in some embodiments of the UEP. In some implementations, a social pay server  4613   a  may be triggered, e.g.,  4621 , to provide services that bridge consumers and merchants over social networks. For example, the social pay server may identify a consumer in need of offers for products or services, and may identify merchants participating in UEP that can provide the needed products or services. The social pay server may generate offers on behalf of the participating merchants, and provide the offers to consumers via social networks. In some embodiments, the social pay server may periodically initiate merchant-consumer bridging services for a user. In alternate embodiments, the social pay server may initiate merchant-consumer bridging upon notification of a consumer engaging in a transaction (e.g., a consumer may request checkout for a purchase via the user&#39;s virtual wallet; for illustration, see the example User Purchase Checkout (UPC) component  5600  described further below in the discussion with reference to  FIG. 56 ), or when a authorization is requested for a purchase transaction (see the example Purchase Transaction Authorization (PTA) component  5800  described further below in the discussion with reference to  FIG. 58 ). Upon obtaining a trigger to perform merchant-consumer bridging, the social pay server may invoke  4622  a transaction data aggregation component, e.g., the TDA component  2600  described further below in the discussion with reference to  FIG. 26 . The social pay server may query a social pay database  4603   b  for offer generation rules, e.g.,  4623 . For example, the social pay server may utilize PHP/SQL commands similar to the other examples described herein. In response, the database may provide the requested offer generation rules, e.g.,  4624 . Using the aggregated transaction data and the offer generation rules, the social pay server may generate merchant(s) offer social post messages for posting to profiles of the user on social networks, e.g.,  4625 . For example, the social pay server may invoke a transaction-based offer generation component, such as the example UBOR  3900  component described further below in the discussion with reference to  FIG. 39 . The social pay server may provide the generated social post messages  4626  to a social network server  4614   a . The social network server may store the social post messages  4627  to a social network database  4614   b  for distribution to the user (e.g., when the user logs onto the social networking service provided by the social network server). 
       FIG. 47  shows a logic flow diagram illustrating example aspects of social merchant consumer bridging in some embodiments of the UEP, e.g., a Social Merchant Consumer Bridging (“SMCB”) component  4700 . In some implementations, a social pay server may be triggered to provide services that bridge consumers and merchants over social networks, e.g.,  4701 . Upon obtaining a trigger to perform merchant-consumer bridging, the social pay server may invoke a transaction data aggregation component such as the TDA component  2600  described further below in the discussion with reference to  FIG. 26 , e.g.,  4702 . The social pay server may query a social pay database for offer generation rules, e.g.,  4703 . For example, the social pay server may utilize PHP/SQL commands similar to the other examples described herein. In response, the database may provide the requested offer generation rules, e.g.,  4704 . Using the aggregated transaction data and the offer generation rules, the social pay server may generate merchant(s) offer social post messages for posting to profiles of the user on social networks, e.g.,  4705 . For example, the social pay server may invoke a transaction-based offer generation component, such as the example UBOR  3900  component described further below in the discussion with reference to  FIG. 39 . The social pay server may provide the generated social post messages to a social network server. The social network server may store the social post messages to a social network database for distribution to the user (e.g., when the user logs onto the social networking service provided by the social network server). In some embodiments, the social network server may generate, using social graph data of the user, social post messages for the user and/or members of the user&#39;s social graph, e.g.,  4706 , and store the social post message in a social network database for posting to their profiles, e.g.,  4707 . 
     Virtual Wallet UI Embodiments 
       FIG. 48  shows a user interface diagram illustrating an overview of example features of virtual wallet applications in some embodiments of the UEP.  FIG. 48  shows an illustration of various exemplary features of a virtual wallet mobile application  4800 . Some of the features displayed include a wallet  4801 , social integration via TWITTER, FACEBOOK, etc., offers and loyalty  4803 , snap mobile purchase  4804 , alerts  4805  and security, setting and analytics  4896 . These features are explored in further detail below. 
       FIGS. 49A-G  show user interface diagrams illustrating example features of virtual wallet applications in a shopping mode, in some embodiments of the UEP. With reference to  FIG. 49A , some embodiments of the virtual wallet mobile app facilitate and greatly enhance the shopping experience of consumers. A variety of shopping modes, as shown in  FIG. 49A , may be available for a consumer to peruse. In one implementation, for example, a user may launch the shopping mode by selecting the shop icon  4910  at the bottom of the user interface. A user may type in an item in the search field  4912  to search and/or add an item to a cart  4911 . A user may also use a voice activated shopping mode by saying the name or description of an item to be searched and/or added to the cart into a microphone  4913 . In a further implementation, a user may also select other shopping options  4914  such as current items  4915 , bills  4916 , address book  4917 , merchants  4918  and local proximity  4919 . 
     In one embodiment, for example, a user may select the option current items  4915 , as shown in the left most user interface of  FIG. 49A . When the current items  4915  option is selected, the middle user interface may be displayed. As shown, the middle user interface may provide a current list of items  4915   a - h  in a user&#39;s shopping cart  4911 . A user may select an item, for example item  4915   a , to view product description  4915   j  of the selected item and/or other items from the same merchant. The price and total payable information may also be displayed, along with a QR code  4915   k  that captures the information necessary to effect a snap mobile purchase transaction. 
     With reference to  FIG. 49B , in another embodiment, a user may select the bills  4916  option. Upon selecting the bills  4916  option, the user interface may display a list of bills and/or receipts  4916   a - h  from one or more merchants. Next to each of the bills, additional information such as date of visit, whether items from multiple stores are present, last bill payment date, auto-payment, number of items, and/or the like may be displayed. In one example, the wallet shop bill  4916   a  dated Jan. 20, 2011 may be selected. The wallet shop bill selection may display a user interface that provides a variety of information regarding the selected bill. For example, the user interface may display a list of items  4916   k  purchased, &lt;&lt; 4916   i &gt;&gt;, a total number of items and the corresponding value. For example, 7 items worth $102.54 were in the selected wallet shop bill. A user may now select any of the items and select buy again to add purchase the items. The user may also refresh offers  4916   j  to clear any invalid offers from last time and/or search for new offers that may be applicable for the current purchase. As shown in  FIG. 49B , a user may select two items for repeat purchase. Upon addition, a message  4916   l  may be displayed to confirm the addition of the two items, which makes the total number of items in the cart  14 . 
     With reference to  FIG. 49C , in yet another embodiment, a user may select the address book option  4917  to view the address book  4917   a  which includes a list of contacts  4917   b  and make any money transfers or payments. In one embodiment, the address book may identify each contact using their names and available and/or preferred modes of payment. For example, a contact Amanda G. may be paid via social pay (e.g., via FACEBOOK) as indicated by the icon  4917   c . In another example, money may be transferred to Brian S. via QR code as indicated by the QR code icon  4917   d . In yet another example, Charles B. may accept payment via near field communication  4917   e , Bluetooth  4917   f  and email  4917   g . Payment may also be made via USB  4917   h  (e.g., by physically connecting two mobile devices) as well as other social channels such as TWITTER. 
     In one implementation, a user may select Joe P. for payment. Joe P., as shown in the user interface, has an email icon  4917   g  next to his name indicating that Joe P. accepts payment via email. When his name is selected, the user interface may display his contact information such as email, phone, etc. If a user wishes to make a payment to Joe P. by a method other than email, the user may add another transfer mode  4917   j  to his contact information and make a payment transfer. With reference to  FIG. 49D , the user may be provided with a screen  4917   k  where the user can enter an amount to send Joe, as well as add other text to provide Joe with context for the payment transaction  4917   l . The user can choose modes (e.g., SMS, email, social networking) via which Joe may be contacted via graphical user interface elements,  4917   m . As the user types, the text entered may be provided for review within a GUI element  4917   n . When the user has completed entering in the necessary information, the user can press the send button  4917   o  to send the social message to Joe. If Joe also has a virtual wallet application, Joe may be able to review  491 ′ 7   p  social pay message within the app, or directly at the website of the social network (e.g., for Twitter™, Facebook®, etc.). Messages may be aggregated from the various social networks and other sources (e.g., SMS, email). The method of redemption appropriate for each messaging mode may be indicated along with the social pay message. In the illustration in  FIG. 49D , the SMS  4917   q  Joe received indicates that Joe can redeem the $5 obtained via SMS by replying to the SMS and entering the hash tag value ‘#1234’. In the same illustration, Joe has also received a message  4917   r  via Facebook®, which includes a URL link that Joe can activate to initiate redemption of the $25 payment. 
     With reference to  FIG. 49E , in some other embodiments, a user may select merchants  4918  from the list of options in the shopping mode to view a select list of merchants  4918   a - e . In one implementation, the merchants in the list may be affiliated to the wallet, or have affinity relationship with the wallet. In another implementation, the merchants may include a list of merchants meeting a user-defined or other criteria. For example, the list may be one that is curated by the user, merchants where the user most frequently shops or spends more than an x amount of sum or shopped for three consecutive months, and/or the like. In one implementation, the user may further select one of the merchants, Amazon  4918   a  for example. The user may then navigate through the merchant&#39;s listings to find items of interest such as  4918   f - j . Directly through the wallet and without visiting the merchant site from a separate page, the user may make a selection of an item  4918   j  from the catalog of Amazon  4918   a . As shown in the right most user interface of  FIG. 49D , the selected item may then be added to cart. The message  4918   k  indicates that the selected item has been added to the cart, and updated number of items in the cart is now 13. 
     With reference to  FIG. 49F , in one embodiment, there may be a local proximity option  4919  which may be selected by a user to view a list of merchants that are geographically in close proximity to the user. For example, the list of merchants  4919   a - e  may be the merchants that are located close to the user. In one implementation, the mobile application may further identify when the user in a store based on the user&#39;s location. For example, position icon  4919   d  may be displayed next to a store (e.g., Walgreens) when the user is in close proximity to the store. In one implementation, the mobile application may refresh its location periodically in case the user moved away from the store (e.g., Walgreens). In a further implementation, the user may navigate the offerings of the selected Walgreens store through the mobile application. For example, the user may navigate, using the mobile application, to items  4919   f - j  available on aisle 5 of Walgreens. In one implementation, the user may select corn  4919   i  from his or her mobile application to add to cart  4919   k.    
     With reference to  FIG. 49G , in another embodiment, the local proximity option  4919  may include a store map and a real time map features among others. For example, upon selecting the Walgreens store, the user may launch an aisle map  4919   l  which displays a map  4919   m  showing the organization of the store and the position of the user (indicated by a yellow circle). In one implementation, the user may easily configure the map to add one or more other users (e.g., user&#39;s kids) to share each other&#39;s location within the store. In another implementation, the user may have the option to launch a “store view” similar to street views in maps. The store view  4919   n  may display images/video of the user&#39;s surrounding. For example, if the user is about to enter aisle 5, the store view map may show the view of aisle 5. Further the user may manipulate the orientation of the map using the navigation tool  4919   o  to move the store view forwards, backwards, right, left as well clockwise and counterclockwise rotation 
       FIGS. 50A-F  show user interface diagrams illustrating example features of virtual wallet applications in a payment mode, in some embodiments of the UEP. With reference to  FIG. 50A , in one embodiment, the wallet mobile application may provide a user with a number of options for paying for a transaction via the wallet mode  5010 . In one implementation, an example user interface  5011  for making a payment is shown. The user interface may clearly identify the amount  5012  and the currency  5013  for the transaction. The amount may be the amount payable and the currency may include real currencies such as dollars and euros, as well as virtual currencies such as reward points. The amount of the transaction  5014  may also be prominently displayed on the user interface. The user may select the funds tab  5016  to select one or more forms of payment  5017 , which may include various credit, debit, gift, rewards and/or prepaid cards. The user may also have the option of paying, wholly or in part, with reward points. For example, the graphical indicator  5018  on the user interface shows the number of points available, the graphical indicator  5019  shows the number of points to be used towards the amount due 234.56 and the equivalent  5020  of the number of points in a selected currency (USD, for example). 
     In one implementation, the user may combine funds from multiple sources to pay for the transaction. The amount  5015  displayed on the user interface may provide an indication of the amount of total funds covered so far by the selected forms of payment (e.g., Discover card and rewards points). The user may choose another form of payment or adjust the amount to be debited from one or more forms of payment until the amount  5015  matches the amount payable  5014 . Once the amounts to be debited from one or more forms of payment are finalized by the user, payment authorization may begin. 
     In one implementation, the user may select a secure authorization of the transaction by selecting the cloak button  5022  to effectively cloak or anonymize some (e.g., pre-configured) or all identifying information such that when the user selects pay button  5021 , the transaction authorization is conducted in a secure and anonymous manner. In another implementation, the user may select the pay button  5021  which may use standard authorization techniques for transaction processing. In yet another implementation, when the user selects the social button  5023 , a message regarding the transaction may be communicated to one of more social networks (set up by the user) which may post or announce the purchase transaction in a social forum such as a wall post or a tweet. In one implementation, the user may select a social payment processing option  5023 . The indicator  5024  may show the authorizing and sending social share data in progress. 
     In another implementation, a restricted payment mode  5025  may be activated for certain purchase activities such as prescription purchases. The mode may be activated in accordance with rules defined by issuers, insurers, merchants, payment processor and/or other entities to facilitate processing of specialized goods and services. In this mode, the user may scroll down the list of forms of payments  5026  under the funds tab to select specialized accounts such as a flexible spending account (FSA)  5027 , health savings account (HAS), and/or the like and amounts to be debited to the selected accounts. In one implementation, such restricted payment mode  5025  processing may disable social sharing of purchase information. 
     In one embodiment, the wallet mobile application may facilitate importing of funds via the import funds user interface  5028 . For example, a user who is unemployed may obtain unemployment benefit fund  5029  via the wallet mobile application. In one implementation, the entity providing the funds may also configure rules for using the fund as shown by the processing indicator message  5030 . The wallet may read and apply the rules prior, and may reject any purchases with the unemployment funds that fail to meet the criteria set by the rules. Example criteria may include, for example, merchant category code (MCC), time of transaction, location of transaction, and/or the like. As an example, a transaction with a grocery merchant having MCC  5411  may be approved, while a transaction with a bar merchant having an MCC  5813  may be refused. 
     With reference to  FIG. 50B , in one embodiment, the wallet mobile application may facilitate dynamic payment optimization based on factors such as user location, preferences and currency value preferences among others. For example, when a user is in the United States, the country indicator  5031  may display a flag of the United States and may set the currency  5033  to the United States. In a further implementation, the wallet mobile application may automatically rearrange the order in which the forms of payments  5035  are listed to reflect the popularity or acceptability of various forms of payment. In one implementation, the arrangement may reflect the user&#39;s preference, which may not be changed by the wallet mobile application. 
     Similarly, when a German user operates a wallet in Germany, the mobile wallet application user interface may be dynamically updated to reflect the country of operation  5032  and the currency  5034 . In a further implementation, the wallet application may rearrange the order in which different forms of payment  5036  are listed based on their acceptance level in that country. Of course, the order of these forms of payments may be modified by the user to suit his or her own preferences. 
     With reference to  FIG. 50C , in one embodiment, the payee tab  5037  in the wallet mobile application user interface may facilitate user selection of one or more payees receiving the funds selected in the funds tab. In one implementation, the user interface may show a list of all payees  5038  with whom the user has previously transacted or available to transact. The user may then select one or more payees. The payees  5038  may include larger merchants such as Amazon.com Inc., and individuals such as Jane P. Doe. Next to each payee name, a list of accepted payment modes for the payee may be displayed. In one implementation, the user may select the payee Jane P. Doe  5039  for receiving payment. Upon selection, the user interface may display additional identifying information relating to the payee. 
     With reference to  FIG. 50D , in one embodiment, the mode tab  5040  may facilitate selection of a payment mode accepted by the payee. A number of payment modes may be available for selection. Example modes include, blue tooth  5041 , wireless  5042 , snap mobile by user-obtained QR code  5043 , secure chip  5044 , TWITTER  5045 , near-field communication (NFC)  5046 , cellular  5047 , snap mobile by user-provided QR code  5048 , USB  5049  and FACEBOOK  5050 , among others. In one implementation, only the payment modes that are accepted by the payee may be selectable by the user. Other non-accepted payment modes may be disabled. 
     With reference to  FIG. 50E , in one embodiment, the offers tab  5051  may provide real-time offers that are relevant to items in a user&#39;s cart for selection by the user. The user may select one or more offers from the list of applicable offers  5052  for redemption. In one implementation, some offers may be combined, while others may not. When the user selects an offer that may not be combined with another offer, the unselected offers may be disabled. In a further implementation, offers that are recommended by the wallet application&#39;s recommendation engine may be identified by an indicator, such as the one shown by  5053 . In a further implementation, the user may read the details of the offer by expanding the offer row as shown by  5054  in the user interface. 
     With reference to  FIG. 50F , in one embodiment, the social tab  5055  may facilitate integration of the wallet application with social channels  5056 . In one implementation, a user may select one or more social channels  5056  and may sign in to the selected social channel from the wallet application by providing to the wallet application the social channel user name and password  5057  and signing in  5058 . The user may then use the social button  5059  to send or receive money through the integrated social channels. In a further implementation, the user may send social share data such as purchase information or links through integrated social channels. In another embodiment, the user supplied login credentials may allow UEP to engage in interception parsing. 
       FIG. 51  shows a user interface diagram illustrating example features of virtual wallet applications, in a history mode, in some embodiments of the UEP. In one embodiment, a user may select the history mode  5110  to view a history of prior purchases and perform various actions on those prior purchases. For example, a user may enter a merchant identifying information such as name, product, MCC, and/or the like in the search bar  5111 . In another implementation, the user may use voice activated search feature by clicking on the microphone icon  5114 . The wallet application may query the storage areas in the mobile device or elsewhere (e.g., one or more databases and/or tables remote from the mobile device) for transactions matching the search keywords. The user interface may then display the results of the query such as transaction  5115 . The user interface may also identify the date  5112  of the transaction, the merchants and items  5113  relating to the transaction, a barcode of the receipt confirming that a transaction was made, the amount of the transaction and any other relevant information. 
     In one implementation, the user may select a transaction, for example transaction  5115 , to view the details of the transaction. For example, the user may view the details of the items associated with the transaction and the amounts  5116  of each item. In a further implementation, the user may select the show option  5117  to view actions  5118  that the user may take in regards to the transaction or the items in the transaction. For example, the user may add a photo to the transaction (e.g., a picture of the user and the iPad the user bought). In a further implementation, if the user previously shared the purchase via social channels, a post including the photo may be generated and sent to the social channels for publishing. In one implementation, any sharing may be optional, and the user, who did not share the purchase via social channels, may still share the photo through one or more social channels of his or her choice directly from the history mode of the wallet application. In another implementation, the user may add the transaction to a group such as company expense, home expense, travel expense or other categories set up by the user. Such grouping may facilitate year-end accounting of expenses, submission of work expense reports, submission for value added tax (VAT) refunds, personal expenses, and/or the like. In yet another implementation, the user may buy one or more items purchased in the transaction. The user may then execute a transaction without going to the merchant catalog or site to find the items. In a further implementation, the user may also cart one or more items in the transaction for later purchase. 
     The history mode, in another embodiment, may offer facilities for obtaining and displaying ratings  5119  of the items in the transaction. The source of the ratings may be the user, the user&#39;s friends (e.g., from social channels, contacts, etc.), reviews aggregated from the web, and/or the like. The user interface in some implementations may also allow the user to post messages to other users of social channels (e.g., TWITTER or FACEBOOK). For example, the display area  5120  shows FACEBOOK message exchanges between two users. In one implementation, a user may share a link via a message  5121 . Selection of such a message having embedded link to a product may allow the user to view a description of the product and/or purchase the product directly from the history mode. 
     In one embodiment, the history mode may also include facilities for exporting receipts. The export receipts pop up  5122  may provide a number of options for exporting the receipts of transactions in the history. For example, a user may use one or more of the options  5125 , which include save (to local mobile memory, to server, to a cloud account, and/or the like), print to a printer, fax, email, and/or the like. The user may utilize his or her address book  5123  to look up email or fax number for exporting. The user may also specify format options  5124  for exporting receipts. Example format options may include, without limitation, text files (.doc, .txt, .rtf, iif, etc.), spreadsheet (.csv, .xls, etc.), image files (.jpg, .tff, .png, etc.), portable document format (.pdf), postscript (.ps), and/or the like. The user may then click or tap the export button  5127  to initiate export of receipts. 
       FIGS. 52A-E  show user interface diagrams illustrating example features of virtual wallet applications in a snap mode, in some embodiments of the UEP. With reference to  FIG. 52A , in one embodiment, a user may select the snap mode  2110  to access its snap features. The snap mode may handle any machine-readable representation of data. Examples of such data may include linear and 2D bar codes such as UPC code and QR codes. These codes may be found on receipts, product packaging, and/or the like. The snap mode may also process and handle pictures of receipts, products, offers, credit cards or other payment devices, and/or the like. An example user interface in snap mode is shown in  FIG. 52A . A user may use his or her mobile phone to take a picture of a QR code  5215  and/or a barcode  5214 . In one implementation, the bar  5213  and snap frame  5215  may assist the user in snapping codes properly. For example, the snap frame  5215 , as shown, does not capture the entirety of the code  5216 . As such, the code captured in this view may not be resolvable as information in the code may be incomplete. This is indicated by the message on the bar  5213  that indicates that the snap mode is still seeking the code. When the code  5216  is completely framed by the snap frame  5215 , the bar message may be updated to, for example, “snap found.” Upon finding the code, in one implementation, the user may initiate code capture using the mobile device camera. In another implementation, the snap mode may automatically snap the code using the mobile device camera. 
     With reference to  FIG. 52B , in one embodiment, the snap mode may facilitate payment reallocation post transaction. For example, a user may buy grocery and prescription items from a retailer Acme Supermarket. The user may, inadvertently or for ease of checkout for example, use his or her Visa card to pay for both grocery and prescription items. However, the user may have an FSA account that could be used to pay for prescription items, and which would provide the user tax benefits. In such a situation, the user may use the snap mode to initiate transaction reallocation. 
     As shown, the user may enter a search term (e.g., bills) in the search bar  2121 . The user may then identify in the tab  5222  the receipt  5223  the user wants to reallocate. Alternatively, the user may directly snap a picture of a barcode on a receipt, and the snap mode may generate and display a receipt  5223  using information from the barcode. The user may now reallocate  5225 . In some implementations, the user may also dispute the transaction  5224  or archive the receipt  5226 . 
     In one implementation, when the reallocate button  5225  is selected, the wallet application may perform optical character recognition (OCR) of the receipt. Each of the items in the receipt may then be examined to identify one or more items which could be charged to which payment device or account for tax or other benefits such as cash back, reward points, etc. In this example, there is a tax benefit if the prescription medication charged to the user&#39;s Visa card is charged to the user&#39;s FSA. The wallet application may then perform the reallocation as the back end. The reallocation process may include the wallet contacting the payment processor to credit the amount of the prescription medication to the Visa card and debit the same amount to the user&#39;s FSA account. In an alternate implementation, the payment processor (e.g., Visa or MasterCard) may obtain and OCR the receipt, identify items and payment accounts for reallocation and perform the reallocation. In one implementation, the wallet application may request the user to confirm reallocation of charges for the selected items to another payment account. The receipt  5227  may be generated after the completion of the reallocation process. As discussed, the receipt shows that some charges have been moved from the Visa account to the FSA. 
     With reference to  FIG. 52C , in one embodiment, the snap mode may facilitate payment via pay code such as barcodes or QR codes. For example, a user may snap a QR code of a transaction that is not yet complete. The QR code may be displayed at a merchant POS terminal, a website, or a web application and may be encoded with information identifying items for purchase, merchant details and other relevant information. When the user snaps such as a QR code, the snap mode may decode the information in the QR code and may use the decoded information to generate a receipt  5232 . Once the QR code is identified, the navigation bar  5231  may indicate that the pay code is identified. The user may now have an option to add to cart  5233 , pay with a default payment account  5234  or pay with wallet  5235 . 
     In one implementation, the user may decide to pay with default  5234 . The wallet application may then use the user&#39;s default method of payment, in this example the wallet, to complete the purchase transaction. Upon completion of the transaction, a receipt may be automatically generated for proof of purchase. The user interface may also be updated to provide other options for handling a completed transaction. Example options include social  5237  to share purchase information with others, reallocate  5238  as discussed with regard to  FIG. 52B , and archive  5239  to store the receipt. 
     With reference to  FIG. 52D , in one embodiment, the snap mode may also facilitate offer identification, application and storage for future use. For example, in one implementation, a user may snap an offer code  5241  (e.g., a bar code, a QR code, and/or the like). The wallet application may then generate an offer text  5242  from the information encoded in the offer code. The user may perform a number of actions on the offer code. For example, the user use the find button  5243  to find all merchants who accept the offer code, merchants in the proximity who accept the offer code, products from merchants that qualify for the offer code, and/or the like. The user may also apply the offer code to items that are currently in the cart using the add to cart button  5244 . Furthermore, the user may also save the offer for future use by selecting the save button  5245 . 
     In one implementation, after the offer or coupon  5246  is applied, the user may have the option to find qualifying merchants and/or products using find, the user may go to the wallet using  5248 , and the user may also save the offer or coupon  5246  for later use. 
     With reference to  FIG. 52E , in one embodiment, the snap mode may also offer facilities for adding a funding source to the wallet application. In one implementation, a pay card such as a credit card, debit card, pre-paid card, smart card and other pay accounts may have an associated code such as a bar code or QR code. Such a code may have encoded therein pay card information including, but not limited to, name, address, pay card type, pay card account details, balance amount, spending limit, rewards balance, and/or the like. In one implementation, the code may be found on a face of the physical pay card. In another implementation, the code may be obtained by accessing an associated online account or another secure location. In yet another implementation, the code may be printed on a letter accompanying the pay card. A user, in one implementation, may snap a picture of the code. The wallet application may identify the pay card  5251  and may display the textual information  5252  encoded in the pay card. The user may then perform verification of the information  5252  by selecting the verify button  5253 . In one implementation, the verification may include contacting the issuer of the pay card for confirmation of the decoded information  5252  and any other relevant information. In one implementation, the user may add the pay card to the wallet by selecting the ‘add to wallet’ button  5254 . The instruction to add the pay card to the wallet may cause the pay card to appear as one of the forms of payment under the funds tab  5016  discussed in  FIG. 50A . The user may also cancel importing of the pay card as a funding source by selecting the cancel button  5255 . When the pay card has been added to the wallet, the user interface may be updated to indicate that the importing is complete via the notification display  5256 . The user may then access the wallet  5257  to begin using the added pay card as a funding source. 
       FIG. 53  shows a user interface diagram illustrating example features of virtual wallet applications, in an offers mode, in some embodiments of the UEP. In some implementations, the UEP may allow a user to search for offers for products and/or services from within the virtual wallet mobile application. For example, the user may enter text into a graphical user interface (“GUI”) element  5311 , or issue voice commands by activating GUI element  5312  and speaking commands into the device. In some implementations, the UEP may provide offers based on the user&#39;s prior behavior, demographics, current location, current cart selection or purchase items, and/or the like. For example, if a user is in a brick-and-mortar store, or an online shopping website, and leaves the (virtual) store, then the merchant associated with the store may desire to provide a sweetener deal to entice the consumer back into the (virtual) store. The merchant may provide such an offer  5313 . For example, the offer may provide a discount, and may include an expiry time. In some implementations, other users may provide gifts (e.g.,  5314 ) to the user, which the user may redeem. In some implementations, the offers section may include alerts as to payment of funds outstanding to other users (e.g.,  5315 ). In some implementations, the offers section may include alerts as to requesting receipt of funds from other users (e.g.,  5316 ). For example, such a feature may identify funds receivable from other applications (e.g., mail, calendar, tasks, notes, reminder programs, alarm, etc.), or by a manual entry by the user into the virtual wallet application. In some implementations, the offers section may provide offers from participating merchants in the UEP, e.g.,  5317 - 5319 ,  5320 . These offers may sometimes be assembled using a combination of participating merchants, e.g.,  5317 . In some implementations, the UEP itself may provide offers for users contingent on the user utilizing particular payment forms from within the virtual wallet application, e.g.,  5320 . 
       FIGS. 54A-B  show user interface diagrams illustrating example features of virtual wallet applications, in a security and privacy mode, in some embodiments of the UEP. With reference to  FIG. 54A , in some implementations, the user may be able to view and/or modify the user profile and/or settings of the user, e.g., by activating a user interface element. For example, the user may be able to view/modify a user name (e.g.,  5411   a - b ), account number (e.g.,  5412   a - b ), user security access code (e.g.,  5413 - b ), user pin (e.g.,  5414 - b ), user address (e.g.,  5415 - b ), social security number associated with the user (e.g.,  5416 - b ), current device GPS location (e.g.,  5417 - b ), user account of the merchant in whose store the user currently is (e.g.,  5418 - b ), the user&#39;s rewards accounts (e.g.,  5419 - b ), and/or the like. In some implementations, the user may be able to select which of the data fields and their associated values should be transmitted to facilitate the purchase transaction, thus providing enhanced data security for the user. For example, in the example illustration in  FIG. 54A , the user has selected the name  5411   a , account number  5412   a , security code  5413   a , merchant account ID  5418   a  and rewards account ID  5419   a  as the fields to be sent as part of the notification to process the purchase transaction. In some implementations, the user may toggle the fields and/or data values that are sent as part of the notification to process the purchase transactions. In some implementations, the app may provide multiple screens of data fields and/or associated values stored for the user to select as part of the purchase order transmission. In some implementations, the app may provide the UEP with the GPS location of the user. Based on the GPS location of the user, the UEP may determine the context of the user (e.g., whether the user is in a store, doctor&#39;s office, hospital, postal service office, etc.). Based on the context, the user app may present the appropriate fields to the user, from which the user may select fields and/or field values to send as part of the purchase order transmission. 
     For example, a user may go to doctor&#39;s office and desire to pay the co-pay for doctor&#39;s appointment. In addition to basic transactional information such as account number and name, the app may provide the user the ability to select to transfer medical records, health information, which may be provided to the medical provider, insurance company, as well as the transaction processor to reconcile payments between the parties. In some implementations, the records may be sent in a Health Insurance Portability and Accountability Act (HIPAA)-compliant data format and encrypted, and only the recipients who are authorized to view such records may have appropriate decryption keys to decrypt and view the private user information. 
     With reference to  FIG. 54B , in some implementations, the app executing on the user&#39;s device may provide a “VerifyChat” feature for fraud prevention. For example, the UEP may detect an unusual and/or suspicious transaction. The UEP may utilize the VerifyChat feature to communicate with the user, and verify the authenticity of the originator of the purchase transaction. In various implementations, the UEP may send electronic mail message, text (SMS) messages, Facebook® messages, Twitter™ tweets, text chat, voice chat, video chat (e.g., Apple FaceTime), and/or the like to communicate with the user. For example, the UEP may initiate a video challenge for the user, e.g.,  5421 . For example, the user may need to present him/her-self via a video chat, e.g.,  5422 . In some implementations, a customer service representative, e.g., agent  5424 , may manually determine the authenticity of the user using the video of the user. In some implementations, the UEP may utilize face, biometric and/or like recognition (e.g., using pattern classification techniques) to determine the identity of the user. In some implementations, the app may provide reference marker (e.g., cross-hairs, target box, etc.), e.g.,  5423 , so that the user may the video to facilitate the UEP&#39;s automated recognition of the user. In some implementations, the user may not have initiated the transaction, e.g., the transaction is fraudulent. In such implementations, the user may cancel the challenge. The UEP may then cancel the transaction, and/or initiate fraud investigation procedures on behalf of the user. 
     In some implementations, the UEP may utilize a text challenge procedure to verify the authenticity of the user, e.g.,  5425 . For example, the UEP may communicate with the user via text chat, SMS messages, electronic mail, Facebook® messages, Twitter™ tweets, and/or the like. The UEP may pose a challenge question, e.g.,  5426 , for the user. The app may provide a user input interface element(s) (e.g., virtual keyboard  5428 ) to answer the challenge question posed by the UEP. In some implementations, the challenge question may be randomly selected by the UEP automatically; in some implementations, a customer service representative may manually communicate with the user. In some implementations, the user may not have initiated the transaction, e.g., the transaction is fraudulent. In such implementations, the user may cancel the text challenge. The UEP may cancel the transaction, and/or initiate fraud investigation on behalf of the user. 
     UEP Transaction Platform 
       FIG. 55  shows a data flow diagram illustrating an example user purchase checkout procedure in some embodiments of the UEP. In some embodiments, a user, e.g.,  5501   a , may desire to purchase a product, service, offering, and/or the like (“product”), from a merchant via a merchant online site or in the merchant&#39;s store. The user may communicate with a merchant/acquirer (“merchant”) server, e.g.,  5503   a , via a client such as, but not limited to: a personal computer, mobile device, television, point-of-sale terminal, kiosk, ATM, and/or the like (e.g.,  5502 ). For example, the user may provide user input, e.g., checkout input  5511 , into the client indicating the user&#39;s desire to purchase the product. In various embodiments, the user input may include, but not be limited to: a single tap (e.g., a one-tap mobile app purchasing embodiment) of a touchscreen interface, keyboard entry, card swipe, activating a RFID/NFC enabled hardware device (e.g., electronic card having multiple accounts, smartphone, tablet, etc.) within the user device, mouse clicks, depressing buttons on a joystick/game console, voice commands, single/multi-touch gestures on a touch-sensitive interface, touching user interface elements on a touch-sensitive display, and/or the like. As an example, a user in a merchant store may scan a product barcode of the product via a barcode scanner at a point-of-sale terminal. As another example, the user may select a product from a webpage catalog on the merchant&#39;s website, and add the product to a virtual shopping cart on the merchant&#39;s website. The user may then indicate the user&#39;s desire to checkout the items in the (virtual) shopping cart. For example, the user may activate a user interface element provided by the client to indicate the user&#39;s desire to complete the user purchase checkout. The client may generate a checkout request, e.g.,  5512 , and provide the checkout request, e.g.,  5513 , to the merchant server. For example, the client may provide a (Secure) Hypertext Transfer Protocol (“HTTP(S)”) POST message including the product details for the merchant server in the form of data formatted according to the eXtensible Markup Language (“XML”). An example listing of a checkout request  5512 , substantially in the form of a HTTP(S) POST message including XML-formatted data, is provided below:

     In some embodiments, the merchant server may obtain the checkout request from the client, and extract the checkout detail (e.g., XML data) from the checkout request. For example, the merchant server may utilize a parser such as the example parsers described below in the discussion with reference to  FIG. 61 . Based on parsing the checkout request  5512 , the merchant server may extract product data (e.g., product identifiers), as well as available PoS client data, from the checkout request. In some embodiments, using the product data, the merchant server may query, e.g.,  5514 , a merchant/acquirer (“merchant”) database, e.g.,  5503   b , to obtain product data, e.g.,  5515 , such as product information, product pricing, sales tax, offers, discounts, rewards, and/or other information to process the purchase transaction and/or provide value-added services for the user. For example, the merchant database may be a relational database responsive to Structured Query Language (“SQL”) commands. The merchant server may execute a hypertext preprocessor (“PHP”) script including SQL commands to query a database table (such as  FIG. 61 , Products  6119   l ) for product data. An example product data query  5514 , substantially in the form of PHP/SQL commands, is provided below:

     In some embodiments, in response to obtaining the product data, the merchant server may generate, e.g.,  5516 , checkout data to provide for the PoS client. In some embodiments, such checkout data, e.g.,  5517 , may be embodied, in part, in a HyperText Markup Language (“HTML”) page including data for display, such as product detail, product pricing, total pricing, tax information, shipping information, offers, discounts, rewards, value-added service information, etc., and input fields to provide payment information to process the purchase transaction, such as account holder name, account number, billing address, shipping address, tip amount, etc. In some embodiments, the checkout data may be embodied, in part, in a Quick Response (“QR”) code image that the PoS client can display, so that the user may capture the QR code using a user&#39;s device to obtain merchant and/or product data for generating a purchase transaction processing request. In some embodiments, a user alert mechanism may be built into the checkout data. For example, the merchant server may embed a URL specific to the transaction into the checkout data. In some embodiments, the alerts URL may further be embedded into optional level 3 data in card authorization requests, such as those discussed further below with reference to  FIGS. 57-58 . The URL may point to a webpage, data file, executable script, etc., stored on the merchant&#39;s server dedicated to the transaction that is the subject of the card authorization request. For example, the object pointed to by the URL may include details on the purchase transaction, e.g., products being purchased, purchase cost, time expiry, status of order processing, and/or the like. Thus, the merchant server may provide to the payment network the details of the transaction by passing the URL of the webpage to the payment network. In some embodiments, the payment network may provide notifications to the user, such as a payment receipt, transaction authorization confirmation message, shipping notification and/or the like. In such messages, the payment network may provide the URL to the user device. The user may navigate to the URL on the user&#39;s device to obtain alerts regarding the user&#39;s purchase, as well as other information such as offers, coupons, related products, rewards notifications, and/or the like.

     Upon obtaining the checkout data, e.g.,  5517 , the PoS client may render and display, e.g.,  5518 , the checkout data for the user. 
       FIG. 56  shows a logic flow diagram illustrating example aspects of a user purchase checkout in some embodiments of the UEP, e.g., a User Purchase Checkout (“UPC”) component  5600 . In some embodiments, a user may desire to purchase a product, service, offering, and/or the like (“product”), from a merchant via a merchant online site or in the merchant&#39;s store. The user may communicate with a merchant/acquirer (“merchant”) server via a PoS client. For example, the user may provide user input, e.g.,  5601 , into the client indicating the user&#39;s desire to purchase the product. The client may generate a checkout request, e.g.,  5602 , and provide the checkout request to the merchant server. In some embodiments, the merchant server may obtain the checkout request from the client, and extract the checkout detail (e.g., XML data) from the checkout request. For example, the merchant server may utilize a parser such as the example parsers described below in the discussion with reference to  FIG. 61 . Based on parsing the checkout request, the merchant server may extract product data (e.g., product identifiers), as well as available PoS client data, from the checkout request. In some embodiments, using the product data, the merchant server may query, e.g.,  5603 , a merchant/acquirer (“merchant”) database to obtain product data, e.g.,  5604 , such as product information, product pricing, sales tax, offers, discounts, rewards, and/or other information to process the purchase transaction and/or provide value-added services for the user. In some embodiments, in response to obtaining the product data, the merchant server may generate, e.g.,  5605 , checkout data to provide, e.g.,  5606 , for the PoS client. Upon obtaining the checkout data, the PoS client may render and display, e.g.,  5607 , the checkout data for the user. 
       FIGS. 57A-B  show data flow diagrams illustrating an example purchase transaction authorization procedure in some embodiments of the UEP. With reference to  FIG. 57A , in some embodiments, a user, e.g.,  5701   a , may wish to utilize a virtual wallet account to purchase a product, service, offering, and/or the like (“product”), from a merchant via a merchant online site or in the merchant&#39;s store. The user may utilize a physical card, or a user wallet device, e.g.,  5701   b , to access the user&#39;s virtual wallet account. For example, the user wallet device may be a personal/laptop computer, cellular telephone, smartphone, tablet, eBook reader, netbook, gaming console, and/or the like. The user may provide a wallet access input, e.g.,  5711  into the user wallet device. In various embodiments, the user input may include, but not be limited to: a single tap (e.g., a one-tap mobile app purchasing embodiment) of a touchscreen interface, keyboard entry, card swipe, activating a RFID/NFC enabled hardware device (e.g., electronic card having multiple accounts, smartphone, tablet, etc.) within the user device, mouse clicks, depressing buttons on a joystick/game console, voice commands, single/multi-touch gestures on a touch-sensitive interface, touching user interface elements on a touch-sensitive display, and/or the like. In some embodiments, the user wallet device may authenticate the user based on the user&#39;s wallet access input, and provide virtual wallet features for the user. 
     In some embodiments, upon authenticating the user for access to virtual wallet features, the user wallet device may provide a transaction authorization input, e.g.,  5714 , to a point-of-sale (“PoS”) client, e.g.,  5702 . For example, the user wallet device may communicate with the PoS client via Bluetooth, Wi-Fi, cellular communication, one- or two-way near-field communication (“NFC”), and/or the like. In embodiments where the user utilizes a plastic card instead of the user wallet device, the user may swipe the plastic card at the PoS client to transfer information from the plastic card into the PoS client. For example, the PoS client may obtain, as transaction authorization input  5714 , track 1 data from the user&#39;s plastic card (e.g., credit card, debit card, prepaid card, charge card, etc.), such as the example track 1 data provided below:

                 randomly each time the card is used.) 
               
               
                   
                   
               
            
           
         
       
     
     In embodiments where the user utilizes a user wallet device, the user wallet device may provide payment information to the PoS client, formatted according to a data formatting protocol appropriate to the communication mechanism employed in the communication between the user wallet device and the PoS client.

     In some embodiments, the PoS client may generate a card authorization request, e.g.,  5715 , using the obtained transaction authorization input from the user wallet device, and/or product/checkout data (see, e.g.,  FIG. 55, 5515-5517 ). An example listing of a card authorization request  5715 , substantially in the form of a HTTP(S) POST message including XML-formatted data, is provided below:

     In some embodiments, the card authorization request generated by the user device may include a minimum of information required to process the purchase transaction. For example, this may improve the efficiency of communicating the purchase transaction request, and may also advantageously improve the privacy protections provided to the user and/or merchant. For example, in some embodiments, the card authorization request may include at least a session ID for the user&#39;s shopping session with the merchant. The session ID may be utilized by any component and/or entity having the appropriate access authority to access a secure site on the merchant server to obtain alerts, reminders, and/or other data about the transaction(s) within that shopping session between the user and the merchant. In some embodiments, the PoS client may provide the generated card authorization request to the merchant server, e.g.,  5716 . The merchant server may forward the card authorization request to a pay gateway server, e.g.,  5704   a , for routing the card authorization request to the appropriate payment network for payment processing. For example, the pay gateway server may be able to select from payment networks, such as Visa, Mastercard, American Express, Paypal, etc., to process various types of transactions including, but not limited to: credit card, debit card, prepaid card, B2B and/or like transactions. In some embodiments, the merchant server may query a database, e.g., merchant/acquirer database  5703   b , for a network address of the payment gateway server, for example by using a portion of a user payment card number, or a user ID (such as an email address) as a keyword for the database query. For example, the merchant server may issue PHP/SQL commands to query a database table (such as  FIG. 61 , Pay Gateways  6119   h ) for a URL of the pay gateway server. An example payment gateway address query  5717 , substantially in the form of PHP/SQL commands, is provided below:

     In response, the merchant/acquirer database may provide the requested payment gateway address, e.g.,  5718 . The merchant server may forward the card authorization request to the pay gateway server using the provided address, e.g.,  5719 . In some embodiments, upon receiving the card authorization request from the merchant server, the pay gateway server may invoke a component to provide one or more services associated with purchase transaction authorization. For example, the pay gateway server may invoke components for fraud prevention, loyalty and/or rewards, and/or other services for which the user-merchant combination is authorized. The pay gateway server may forward the card authorization request to a pay network server, e.g.,  5705   a , for payment processing. For example, the pay gateway server may be able to select from payment networks, such as Visa, Mastercard, American Express, Paypal, etc., to process various types of transactions including, but not limited to: credit card, debit card, prepaid card, B2B and/or like transactions. In some embodiments, the pay gateway server may query a database, e.g., pay gateway database  5704   b , for a network address of the payment network server, for example by using a portion of a user payment card number, or a user ID (such as an email address) as a keyword for the database query. For example, the pay gateway server may issue PHP/SQL commands to query a database table (such as  FIG. 61 , Pay Gateways  6119   h ) for a URL of the pay network server.

     In response, the payment gateway database may provide the requested payment network address, e.g.,  5722 . The pay gateway server may forward the card authorization request to the pay network server using the provided address, e.g.,  5723 . 
     With reference to  FIG. 57B , in some embodiments, the pay network server may process the transaction so as to transfer funds for the purchase into an account stored on an acquirer of the merchant. For example, the acquirer may be a financial institution maintaining an account of the merchant. For example, the proceeds of transactions processed by the merchant may be deposited into an account maintained by at a server of the acquirer. 
     In some embodiments, the pay network server may generate a query, e.g.,  5724 , for issuer server(s) corresponding to the user-selected payment options. For example, the user&#39;s account may be linked to one or more issuer financial institutions (“issuers”), such as banking institutions, which issued the account(s) for the user. For example, such accounts may include, but not be limited to: credit card, debit card, prepaid card, checking, savings, money market, certificates of deposit, stored (cash) value accounts and/or the like. Issuer server(s), e.g.,  5706   a , of the issuer(s) may maintain details of the user&#39;s account(s). In some embodiments, a database, e.g., pay network database  5705   b , may store details of the issuer server(s) associated with the issuer(s). In some embodiments, the pay network server may query a database, e.g., pay network database  5705   b , for a network address of the issuer(s) server(s), for example by using a portion of a user payment card number, or a user ID (such as an email address) as a keyword for the database query. For example, the merchant server may issue PHP/SQL commands to query a database table (such as  FIG. 61 , Issuers  6119   f ) for network address(es) of the issuer(s) server(s). An example issuer server address(es) query  5724 , substantially in the form of PHP/SQL commands, is provided below:

     In response to obtaining the issuer server query, e.g.,  5724 , the pay network database may provide, e.g.,  5725 , the requested issuer server data to the pay network server. In some embodiments, the pay network server may utilize the issuer server data to generate funds authorization request(s), e.g.,  5726 , for each of the issuer server(s) selected based on the pre-defined payment settings associated with the user&#39;s virtual wallet, and/or the user&#39;s payment options input, and provide the funds authorization request(s) to the issuer server(s). In some embodiments, the funds authorization request(s) may include details such as, but not limited to: the costs to the user involved in the transaction, card account details of the user, user billing and/or shipping information, and/or the like.

     In some embodiments, an issuer server may parse the authorization request(s), and based on the request details may query a database, e.g., user profile database  5706   b , for data associated with an account linked to the user. For example, the merchant server may issue PHP/SQL commands to query a database table (such as  FIG. 61 , Accounts  6119   d ) for user account(s) data. An example user account(s) query  5727 , substantially in the form of PHP/SQL commands, is provided below:

     In some embodiments, on obtaining the user account(s) data, e.g.,  5728 , the issuer server may determine whether the user can pay for the transaction using funds available in the account,  5729 . For example, the issuer server may determine whether the user has a sufficient balance remaining in the account, sufficient credit associated with the account, and/or the like. Based on the determination, the issuer server(s) may provide a funds authorization response, e.g.,  5730 , to the pay network server. For example, the issuer server(s) may provide a HTTP(S) POST message similar to the examples above. In some embodiments, if at least one issuer server determines that the user cannot pay for the transaction using the funds available in the account, the pay network server may request payment options again from the user (e.g., by providing an authorization fail message to the user device and requesting the user device to provide new payment options), and re-attempt authorization for the purchase transaction. In some embodiments, if the number of failed authorization attempts exceeds a threshold, the pay network server may abort the authorization process, and provide an “authorization fail” message to the merchant server, user device and/or client. 
     In some embodiments, the pay network server may obtain the funds authorization response including a notification of successful authorization, and parse the message to extract authorization details. Upon determining that the user possesses sufficient funds for the transaction, e.g.,  5731 , the pay network server may invoke a component to provide value-add services for the user. 
     In some embodiments, the pay network server may generate a transaction data record from the authorization request and/or authorization response, and store the details of the transaction and authorization relating to the transaction in a transactions database. For example, the pay network server may issue PHP/SQL commands to store the data to a database table (such as  FIG. 61 , Transactions  6119   i ). An example transaction store command, substantially in the form of PHP/SQL commands, is provided below:

     In some embodiments, the pay network server may forward a transaction authorization response, e.g.,  5732 , to the user wallet device, PoS client, and/or merchant server. The merchant may obtain the transaction authorization response, and determine from it that the user possesses sufficient funds in the card account to conduct the transaction. The merchant server may add a record of the transaction for the user to a batch of transaction data relating to authorized transactions. For example, the merchant may append the XML data pertaining to the user transaction to an XML data file comprising XML data for transactions that have been authorized for various users, e.g.,  5733 , and store the XML data file, e.g.,  5734 , in a database, e.g., merchant database  404 . For example, a batch XML data file may be structured similar to the example XML data structure template provided below:

     In some embodiments, the server may also generate a purchase receipt, e.g.,  5733 , and provide the purchase receipt to the client, e.g.,  5735 . The client may render and display, e.g.,  5736 , the purchase receipt for the user. In some embodiments, the user&#39;s wallet device may also provide a notification of successful authorization to the user. For example, the PoS client/user device may render a webpage, electronic message, text/SMS message, buffer a voicemail, emit a ring tone, and/or play an audio message, etc., and provide output including, but not limited to: sounds, music, audio, video, images, tactile feedback, vibration alerts (e.g., on vibration-capable client devices such as a smartphone etc.), and/or the like. 
       FIGS. 58A-B  show logic flow diagrams illustrating example aspects of purchase transaction authorization in some embodiments of the UEP, e.g., a Purchase Transaction Authorization (“PTA”) component  5800 . With reference to  FIG. 58A , in some embodiments, a user may wish to utilize a virtual wallet account to purchase a product, service, offering, and/or the like (“product”), from a merchant via a merchant online site or in the merchant&#39;s store. The user may utilize a physical card, or a user wallet device to access the user&#39;s virtual wallet account. For example, the user wallet device may be a personal/laptop computer, cellular telephone, smartphone, tablet, eBook reader, netbook, gaming console, and/or the like. The user may provide a wallet access input, e.g.,  5801 , into the user wallet device. In various embodiments, the user input may include, but not be limited to: a single tap (e.g., a one-tap mobile app purchasing embodiment) of a touchscreen interface, keyboard entry, card swipe, activating a RFID/NFC enabled hardware device (e.g., electronic card having multiple accounts, smartphone, tablet, etc.) within the user device, mouse clicks, depressing buttons on a joystick/game console, voice commands, single/multi-touch gestures on a touch-sensitive interface, touching user interface elements on a touch-sensitive display, and/or the like. In some embodiments, the user wallet device may authenticate the user based on the user&#39;s wallet access input, and provide virtual wallet features for the user, e.g.,  5802 - 5803 . 
     In some embodiments, upon authenticating the user for access to virtual wallet features, the user wallet device may provide a transaction authorization input, e.g.,  5804 , to a point-of-sale (“PoS”) client. For example, the user wallet device may communicate with the PoS client via Bluetooth, Wi-Fi, cellular communication, one- or two-way near-field communication (“NFC”), and/or the like. In embodiments where the user utilizes a plastic card instead of the user wallet device, the user may swipe the plastic card at the PoS client to transfer information from the plastic card into the PoS client. In embodiments where the user utilizes a user wallet device, the user wallet device may provide payment information to the PoS client, formatted according to a data formatting protocol appropriate to the communication mechanism employed in the communication between the user wallet device and the PoS client. 
     In some embodiments, the PoS client may obtain the transaction authorization input, and parse the input to extract payment information from the transaction authorization input, e.g.,  5805 . For example, the PoS client may utilize a parser, such as the example parsers provided below in the discussion with reference to  FIG. 61 . The PoS client may generate a card authorization request, e.g.,  5806 , using the obtained transaction authorization input from the user wallet device, and/or product/checkout data (see, e.g.,  FIG. 55, 5515-5517 ). 
     In some embodiments, the PoS client may provide the generated card authorization request to the merchant server. The merchant server may forward the card authorization request to a pay gateway server, for routing the card authorization request to the appropriate payment network for payment processing. For example, the pay gateway server may be able to select from payment networks, such as Visa, Mastercard, American Express, Paypal, etc., to process various types of transactions including, but not limited to: credit card, debit card, prepaid card, B2B and/or like transactions. In some embodiments, the merchant server may query a database, e.g.,  5808 , for a network address of the payment gateway server, for example by using a portion of a user payment card number, or a user ID (such as an email address) as a keyword for the database query. In response, the merchant/acquirer database may provide the requested payment gateway address, e.g.,  5810 . The merchant server may forward the card authorization request to the pay gateway server using the provided address. In some embodiments, upon receiving the card authorization request from the merchant server, the pay gateway server may invoke a component to provide one or more service associated with purchase transaction authorization, e.g.,  5811 . For example, the pay gateway server may invoke components for fraud prevention, loyalty and/or rewards, and/or other services for which the user-merchant combination is authorized. 
     The pay gateway server may forward the card authorization request to a pay network server for payment processing, e.g.,  5814 . For example, the pay gateway server may be able to select from payment networks, such as Visa, Mastercard, American Express, Paypal, etc., to process various types of transactions including, but not limited to: credit card, debit card, prepaid card, B2B and/or like transactions. In some embodiments, the pay gateway server may query a database, e.g.,  5812 , for a network address of the payment network server, for example by using a portion of a user payment card number, or a user ID (such as an email address) as a keyword for the database query. In response, the payment gateway database may provide the requested payment network address, e.g.,  5813 . The pay gateway server may forward the card authorization request to the pay network server using the provided address, e.g.,  5814 . 
     With reference to  FIG. 58B , in some embodiments, the pay network server may process the transaction so as to transfer funds for the purchase into an account stored on an acquirer of the merchant. For example, the acquirer may be a financial institution maintaining an account of the merchant. For example, the proceeds of transactions processed by the merchant may be deposited into an account maintained by at a server of the acquirer. In some embodiments, the pay network server may generate a query, e.g.,  5815 , for issuer server(s) corresponding to the user-selected payment options. For example, the user&#39;s account may be linked to one or more issuer financial institutions (“issuers”), such as banking institutions, which issued the account(s) for the user. For example, such accounts may include, but not be limited to: credit card, debit card, prepaid card, checking, savings, money market, certificates of deposit, stored (cash) value accounts and/or the like. Issuer server(s) of the issuer(s) may maintain details of the user&#39;s account(s). In some embodiments, a database, e.g., a pay network database, may store details of the issuer server(s) associated with the issuer(s). In some embodiments, the pay network server may query a database, e.g.,  5815 , for a network address of the issuer(s) server(s), for example by using a portion of a user payment card number, or a user ID (such as an email address) as a keyword for the database query. 
     In response to obtaining the issuer server query, the pay network database may provide, e.g.,  5816 , the requested issuer server data to the pay network server. In some embodiments, the pay network server may utilize the issuer server data to generate funds authorization request(s), e.g.,  5817 , for each of the issuer server(s) selected based on the pre-defined payment settings associated with the user&#39;s virtual wallet, and/or the user&#39;s payment options input, and provide the funds authorization request(s) to the issuer server(s). In some embodiments, the funds authorization request(s) may include details such as, but not limited to: the costs to the user involved in the transaction, card account details of the user, user billing and/or shipping information, and/or the like. In some embodiments, an issuer server may parse the authorization request(s), e.g.,  5818 , and based on the request details may query a database, e.g.,  5819 , for data associated with an account linked to the user. 
     In some embodiments, on obtaining the user account(s) data, e.g.,  5820 , the issuer server may determine whether the user can pay for the transaction using funds available in the account, e.g.,  5821 . For example, the issuer server may determine whether the user has a sufficient balance remaining in the account, sufficient credit associated with the account, and/or the like. Based on the determination, the issuer server(s) may provide a funds authorization response, e.g.,  5822 , to the pay network server. In some embodiments, if at least one issuer server determines that the user cannot pay for the transaction using the funds available in the account, the pay network server may request payment options again from the user (e.g., by providing an authorization fail message to the user device and requesting the user device to provide new payment options), and re-attempt authorization for the purchase transaction. In some embodiments, if the number of failed authorization attempts exceeds a threshold, the pay network server may abort the authorization process, and provide an “authorization fail” message to the merchant server, user device and/or client. 
     In some embodiments, the pay network server may obtain the funds authorization response including a notification of successful authorization, and parse the message to extract authorization details. Upon determining that the user possesses sufficient funds for the transaction, e.g.,  5823 , the pay network server may invoke a component to provide value-add services for the user, e.g.,  5823 . 
     In some embodiments, the pay network server may forward a transaction authorization response to the user wallet device, PoS client, and/or merchant server. The merchant may parse, e.g.,  5824 , the transaction authorization response, and determine from it that the user possesses sufficient funds in the card account to conduct the transaction, e.g.,  5825 , option“Yes.” The merchant server may add a record of the transaction for the user to a batch of transaction data relating to authorized transactions. For example, the merchant may append the XML data pertaining to the user transaction to an XML data file comprising XML data for transactions that have been authorized for various users, e.g.,  5826 , and store the XML data file, e.g.,  5827 , in a database. In some embodiments, the server may also generate a purchase receipt, e.g.,  5828 , and provide the purchase receipt to the client. The client may render and display, e.g.,  5829 , the purchase receipt for the user. In some embodiments, the user&#39;s wallet device may also provide a notification of successful authorization to the user. For example, the PoS client/user device may render a webpage, electronic message, text/SMS message, buffer a voicemail, emit a ring tone, and/or play an audio message, etc., and provide output including, but not limited to: sounds, music, audio, video, images, tactile feedback, vibration alerts (e.g., on vibration-capable client devices such as a smartphone etc.), and/or the like. 
       FIGS. 59A-B  show data flow diagrams illustrating an example purchase transaction clearance procedure in some embodiments of the UEP. With reference to  FIG. 59A , in some embodiments, a merchant server, e.g.,  5903   a , may initiate clearance of a batch of authorized transactions. For example, the merchant server may generate a batch data request, e.g.,  5911 , and provide the request, to a merchant database, e.g.,  5903   b . For example, the merchant server may utilize PHP/SQL commands similar to the examples provided above to query a relational database. In response to the batch data request, the database may provide the requested batch data, e.g.,  5912 . The server may generate a batch clearance request, e.g.,  5913 , using the batch data obtained from the database, and provide, e.g.,  5914 , the batch clearance request to an acquirer server, e.g.,  5907   a . For example, the merchant server may provide a HTTP(S) POST message including XML-formatted batch data in the message body for the acquirer server. The acquirer server may generate, e.g.,  5915 , a batch payment request using the obtained batch clearance request, and provide, e.g.,  5918 , the batch payment request to the pay network server, e.g.,  5905   a . The pay network server may parse the batch payment request, and extract the transaction data for each transaction stored in the batch payment request, e.g.,  5919 . The pay network server may store the transaction data, e.g.,  5920 , for each transaction in a database, e.g., pay network database  5905   b . In some embodiments, the pay network server may invoke a component to provide value-add analytics services based on analysis of the transactions of the merchant for whom the UEP is clearing purchase transactions. Thus, in some embodiments, the pay network server may provide analytics-based value-added services for the merchant and/or the merchant&#39;s users. 
     With reference to  FIG. 59B , in some embodiments, for each extracted transaction, the pay network server may query, e.g.,  5923 , a database, e.g., pay network database  5905   b , for an address of an issuer server. For example, the pay network server may utilize PHP/SQL commands similar to the examples provided above. The pay network server may generate an individual payment request, e.g.,  5925 , for each transaction for which it has extracted transaction data, and provide the individual payment request, e.g.,  5925 , to the issuer server, e.g.,  5906   a . For example, the pay network server may provide an individual payment request to the issuer server(s) as a HTTP(S) POST message including XML-formatted data. An example listing of an individual payment request  5925 , substantially in the form of a HTTP(S) POST message including XML-formatted data, is provided below:

     In some embodiments, the issuer server may generate a payment command, e.g.,  5927 . For example, the issuer server may issue a command to deduct funds from the user&#39;s account (or add a charge to the user&#39;s credit card account). The issuer server may issue a payment command, e.g.,  5927 , to a database storing the user&#39;s account information, e.g., user profile database  5906   b . The issuer server may provide an individual payment confirmation, e.g.,  5928 , to the pay network server, which may forward, e.g.,  5929 , the funds transfer message to the acquirer server. An example listing of an individual payment confirmation  5928 , substantially in the form of a HTTP(S) POST message including XML-formatted data, is provided below:

     In some embodiments, the acquirer server may parse the individual payment confirmation, and correlate the transaction (e.g., using the request ID field in the example above) to the merchant. The acquirer server may then transfer the funds specified in the funds transfer message to an account of the merchant. For example, the acquirer server may query, e.g.  5930 , an acquirer database  5907   b  for payment ledger and/or merchant account data, e.g.,  5931 . The acquirer server may utilize payment ledger and/or merchant account data from the acquirer database, along with the individual payment confirmation, to generate updated payment ledger and/or merchant account data, e.g.,  5932 . The acquirer server may then store, e.g.,  5933 , the updated payment ledger and/or merchant account data to the acquire database. 
       FIGS. 60A-B  show logic flow diagrams illustrating example aspects of purchase transaction clearance in some embodiments of the UEP, e.g., a Purchase Transaction Clearance (“PTC”) component  6000 . With reference to  FIG. 60A , in some embodiments, a merchant server may initiate clearance of a batch of authorized transactions. For example, the merchant server may generate a batch data request, e.g.,  6001 , and provide the request to a merchant database. In response to the batch data request, the database may provide the requested batch data, e.g.,  6002 . The server may generate a batch clearance request, e.g.,  6003 , using the batch data obtained from the database, and provide the batch clearance request to an acquirer server. The acquirer server may parse, e.g.,  6004 , the obtained batch clearance request, and generate, e.g.,  6007 , a batch payment request using the obtained batch clearance request to provide, the batch payment request to a pay network server. For example, the acquirer server may query, e.g.,  6005 , an acquirer database for an address of a payment network server, and utilize the obtained address, e.g.,  6006 , to forward the generated batch payment request to the pay network server. 
     The pay network server may parse the batch payment request obtained from the acquirer server, and extract the transaction data for each transaction stored in the batch payment request, e.g.,  6008 . The pay network server may store the transaction data, e.g.,  6009 , for each transaction in a pay network database. In some embodiments, the pay network server may invoke a component, e.g.,  6010 , to provide analytics based on the transactions of the merchant for whom purchase transaction are being cleared. 
     With reference to  FIG. 60B , in some embodiments, for each extracted transaction, the pay network server may query, e.g.,  6011 , a pay network database for an address of an issuer server. The pay network server may generate an individual payment request, e.g.,  6013 , for each transaction for which it has extracted transaction data, and provide the individual payment request to the issuer server. In some embodiments, the issuer server may parse the individual payment request, e.g.,  6014 , and generate a payment command, e.g.,  6015 , based on the parsed individual payment request. For example, the issuer server may issue a command to deduct funds from the user&#39;s account (or add a charge to the user&#39;s credit card account). The issuer server may issue a payment command, e.g.,  6015 , to a database storing the user&#39;s account information, e.g., a user profile database. The issuer server may provide an individual payment confirmation, e.g.,  6017 , to the pay network server, which may forward, e.g.,  6018 , the individual payment confirmation to the acquirer server. 
     In some embodiments, the acquirer server may parse the individual payment confirmation, and correlate the transaction (e.g., using the request ID field in the example above) to the merchant. The acquirer server may then transfer the funds specified in the funds transfer message to an account of the merchant. For example, the acquirer server may query, e.g.  6019 , an acquirer database for payment ledger and/or merchant account data, e.g.,  6020 . The acquirer server may utilize payment ledger and/or merchant account data from the acquirer database, along with the individual payment confirmation, to generate updated payment ledger and/or merchant account data, e.g.,  6021 . The acquirer server may then store, e.g.,  6022 , the updated payment ledger and/or merchant account data to the acquire database. 
     UEP Controller 
       FIG. 61  shows a block diagram illustrating embodiments of a UEP controller  6101 . In this embodiment, the UEP controller  6101  may serve to aggregate, process, store, search, serve, identify, instruct, generate, match, and/or facilitate interactions with a computer through various technologies, and/or other related data. 
     Typically, users, e.g.,  6133   a , which may be people and/or other systems, may engage information technology systems (e.g., computers) to facilitate information processing. In turn, computers employ processors to process information; such processors  6103  may be referred to as central processing units (CPU). One form of processor is referred to as a microprocessor. CPUs use communicative circuits to pass binary encoded signals acting as instructions to enable various operations. These instructions may be operational and/or data instructions containing and/or referencing other instructions and data in various processor accessible and operable areas of memory  6129  (e.g., registers, cache memory, random access memory, etc.). Such communicative instructions may be stored and/or transmitted in batches (e.g., batches of instructions) as programs and/or data components to facilitate desired operations. These stored instruction codes, e.g., programs, may engage the CPU circuit components and other motherboard and/or system components to perform desired operations. One type of program is a computer operating system, which, may be executed by CPU on a computer; the operating system enables and facilitates users to access and operate computer information technology and resources. Some resources that may be employed in information technology systems include: input and output mechanisms through which data may pass into and out of a computer; memory storage into which data may be saved; and processors by which information may be processed. These information technology systems may be used to collect data for later retrieval, analysis, and manipulation, which may be facilitated through a database program. These information technology systems provide interfaces that allow users to access and operate various system components. 
     In one embodiment, the UEP controller  6101  may be connected to and/or communicate with entities such as, but not limited to: one or more users from user input devices  6111 ; peripheral devices  6112 ; an optional cryptographic processor device  6128 ; and/or a communications network  6113 . For example, the UEP controller  6101  may be connected to and/or communicate with users, e.g.,  6133   a , operating client device(s), e.g.,  6133   b , including, but not limited to, personal computer(s), server(s) and/or various mobile device(s) including, but not limited to, cellular telephone(s), smartphone(s) (e.g., iPhone®, Blackberry®, Android OS-based phones etc.), tablet computer(s) (e.g., Apple iPad™, HP Slate™, Motorola Xoom™, etc.), eBook reader(s) (e.g., Amazon Kindle™, Barnes and Noble&#39;s Nook™ eReader, etc.), laptop computer(s), notebook(s), netbook(s), gaming console(s) (e.g., XBOX Live™, Nintendo® DS, Sony PlayStation® Portable, etc.), portable scanner(s), and/or the like. 
     Networks are commonly thought to comprise the interconnection and interoperation of clients, servers, and intermediary nodes in a graph topology. It should be noted that the term “server” as used throughout this application refers generally to a computer, other device, program, or combination thereof that processes and responds to the requests of remote users across a communications network. Servers serve their information to requesting “clients.” The term “client” as used herein refers generally to a computer, program, other device, user and/or combination thereof that is capable of processing and making requests and obtaining and processing any responses from servers across a communications network. A computer, other device, program, or combination thereof that facilitates, processes information and requests, and/or furthers the passage of information from a source user to a destination user is commonly referred to as a “node.” Networks are generally thought to facilitate the transfer of information from source points to destinations. A node specifically tasked with furthering the passage of information from a source to a destination is commonly called a “router.” There are many forms of networks such as Local Area Networks (LANs), Pico networks, Wide Area Networks (WANs), Wireless Networks (WLANs), etc. For example, the Internet is generally accepted as being an interconnection of a multitude of networks whereby remote clients and servers may access and interoperate with one another. 
     The UEP controller  6101  may be based on computer systems that may comprise, but are not limited to, components such as: a computer systemization  6102  connected to memory  6129 . 
     Computer Systemization 
     A computer systemization  6102  may comprise a clock  6130 , central processing unit (“CPU(s)” and/or “processor(s)” (these terms are used interchangeable throughout the disclosure unless noted to the contrary))  6103 , a memory  6129  (e.g., a read only memory (ROM)  6106 , a random access memory (RAM)  6105 , etc.), and/or an interface bus  6107 , and most frequently, although not necessarily, are all interconnected and/or communicating through a system bus  6104  on one or more (mother)board(s)  6102  having conductive and/or otherwise transportive circuit pathways through which instructions (e.g., binary encoded signals) may travel to effectuate communications, operations, storage, etc. The computer systemization may be connected to a power source  6186 ; e.g., optionally the power source may be internal. Optionally, a cryptographic processor  6126  and/or transceivers (e.g., ICs)  6174  may be connected to the system bus. In another embodiment, the cryptographic processor and/or transceivers may be connected as either internal and/or external peripheral devices  6112  via the interface bus I/O. In turn, the transceivers may be connected to antenna(s)  6175 , thereby effectuating wireless transmission and reception of various communication and/or sensor protocols; for example the antenna(s) may connect to: a Texas Instruments WiLink WL1283 transceiver chip (e.g., providing 802.11n, Bluetooth 3.0, FM, global positioning system (GPS) (thereby allowing UEP controller to determine its location)); Broadcom BCM4329FKUBG transceiver chip (e.g., providing 802.11n, Bluetooth 2.1+EDR, FM, etc.); a Broadcom BCM4750IUB8 receiver chip (e.g., GPS); an Infineon Technologies X-Gold 618-PMB9800 (e.g., providing 2G/3G HSDPA/HSUPA communications); and/or the like. The system clock typically has a crystal oscillator and generates a base signal through the computer systemization&#39;s circuit pathways. The clock is typically coupled to the system bus and various clock multipliers that will increase or decrease the base operating frequency for other components interconnected in the computer systemization. The clock and various components in a computer systemization drive signals embodying information throughout the system. Such transmission and reception of instructions embodying information throughout a computer systemization may be commonly referred to as communications. These communicative instructions may further be transmitted, received, and the cause of return and/or reply communications beyond the instant computer systemization to: communications networks, input devices, other computer systemizations, peripheral devices, and/or the like. It should be understood that in alternative embodiments, any of the above components may be connected directly to one another, connected to the CPU, and/or organized in numerous variations employed as exemplified by various computer systems. 
     The CPU comprises at least one high-speed data processor adequate to execute program components for executing user and/or system-generated requests. Often, the processors themselves will incorporate various specialized processing units, such as, but not limited to: integrated system (bus) controllers, memory management control units, floating point units, and even specialized processing sub-units like graphics processing units, digital signal processing units, and/or the like. Additionally, processors may include internal fast access addressable memory, and be capable of mapping and addressing memory  6129  beyond the processor itself; internal memory may include, but is not limited to: fast registers, various levels of cache memory (e.g., level 1, 2, 3, etc.), RAM, etc. The processor may access this memory through the use of a memory address space that is accessible via instruction address, which the processor can construct and decode allowing it to access a circuit path to a specific memory address space having a memory state. The CPU may be a microprocessor such as: AMD&#39;s Athlon, Duron and/or Opteron; ARM&#39;s application, embedded and secure processors; IBM and/or Motorola&#39;s DragonBall and PowerPC; IBM&#39;s and Sony&#39;s Cell processor; Intel&#39;s Celeron, Core (2) Duo, Itanium, Pentium, Xeon, and/or XScale; and/or the like processor(s). The CPU interacts with memory through instruction passing through conductive and/or transportive conduits (e.g., (printed) electronic and/or optic circuits) to execute stored instructions (i.e., program code) according to conventional data processing techniques. Such instruction passing facilitates communication within the UEP controller and beyond through various interfaces. Should processing requirements dictate a greater amount speed and/or capacity, distributed processors (e.g., Distributed UEP), mainframe, multi-core, parallel, and/or super-computer architectures may similarly be employed. Alternatively, should deployment requirements dictate greater portability, smaller Personal Digital Assistants (PDAs) may be employed. 
     Depending on the particular implementation, features of the UEP may be achieved by implementing a microcontroller such as CAST&#39;s R8051XC2 microcontroller; Intel&#39;s MCS 51 (i.e., 8051 microcontroller); and/or the like. Also, to implement certain features of the UEP, some feature implementations may rely on embedded components, such as: Application-Specific Integrated Circuit (“ASIC”), Digital Signal Processing (“DSP”), Field Programmable Gate Array (“FPGA”), and/or the like embedded technology. For example, any of the UEP component collection (distributed or otherwise) and/or features may be implemented via the microprocessor and/or via embedded components; e.g., via ASIC, coprocessor, DSP, FPGA, and/or the like. Alternately, some implementations of the UEP may be implemented with embedded components that are configured and used to achieve a variety of features or signal processing. 
     Depending on the particular implementation, the embedded components may include software solutions, hardware solutions, and/or some combination of both hardware/software solutions. For example, UEP features discussed herein may be achieved through implementing FPGAs, which are a semiconductor devices containing programmable logic components called “logic blocks”, and programmable interconnects, such as the high performance FPGA Virtex series and/or the low cost Spartan series manufactured by Xilinx. Logic blocks and interconnects can be programmed by the customer or designer, after the FPGA is manufactured, to implement any of the UEP features. A hierarchy of programmable interconnects allow logic blocks to be interconnected as needed by the UEP system designer/administrator, somewhat like a one-chip programmable breadboard. An FPGA&#39;s logic blocks can be programmed to perform the operation of basic logic gates such as AND, and XOR, or more complex combinational operators such as decoders or simple mathematical operations. In most FPGAs, the logic blocks also include memory elements, which may be circuit flip-flops or more complete blocks of memory. In some circumstances, the UEP may be developed on regular FPGAs and then migrated into a fixed version that more resembles ASIC implementations. Alternate or coordinating implementations may migrate UEP controller features to a final ASIC instead of or in addition to FPGAs. Depending on the implementation all of the aforementioned embedded components and microprocessors may be considered the “CPU” and/or “processor” for the UEP. 
     Power Source 
     The power source  6186  may be of any standard form for powering small electronic circuit board devices such as the following power cells: alkaline, lithium hydride, lithium ion, lithium polymer, nickel cadmium, solar cells, and/or the like. Other types of AC or DC power sources may be used as well. In the case of solar cells, in one embodiment, the case provides an aperture through which the solar cell may capture photonic energy. The power cell  6186  is connected to at least one of the interconnected subsequent components of the UEP thereby providing an electric current to all subsequent components. In one example, the power source  6186  is connected to the system bus component  6104 . In an alternative embodiment, an outside power source  6186  is provided through a connection across the I/O  6108  interface. For example, a USB and/or IEEE 1394 connection carries both data and power across the connection and is therefore a suitable source of power. 
     Interface Adapters 
     Interface bus(ses)  6107  may accept, connect, and/or communicate to a number of interface adapters, conventionally although not necessarily in the form of adapter cards, such as but not limited to: input output interfaces (I/O)  6108 , storage interfaces  6109 , network interfaces  6110 , and/or the like. Optionally, cryptographic processor interfaces  6127  similarly may be connected to the interface bus. The interface bus provides for the communications of interface adapters with one another as well as with other components of the computer systemization. Interface adapters are adapted for a compatible interface bus. Interface adapters conventionally connect to the interface bus via a slot architecture. Conventional slot architectures may be employed, such as, but not limited to: Accelerated Graphics Port (AGP), Card Bus, (Extended) Industry Standard Architecture ((E)ISA), Micro Channel Architecture (MCA), NuBus, Peripheral Component Interconnect (Extended) (PCI(X)), PCI Express, Personal Computer Memory Card International Association (PCMCIA), and/or the like. 
     Storage interfaces  6109  may accept, communicate, and/or connect to a number of storage devices such as, but not limited to: storage devices  6114 , removable disc devices, and/or the like. Storage interfaces may employ connection protocols such as, but not limited to: (Ultra) (Serial) Advanced Technology Attachment (Packet Interface) ((Ultra) (Serial) ATA(PI)), (Enhanced) Integrated Drive Electronics ((E)IDE), Institute of Electrical and Electronics Engineers (IEEE) 1394, fiber channel, Small Computer Systems Interface (SCSI), Universal Serial Bus (USB), and/or the like. 
     Network interfaces  6110  may accept, communicate, and/or connect to a communications network  6113 . Through a communications network  6113 , the UEP controller is accessible through remote clients  6133   b  (e.g., computers with web browsers) by users  6133   a . Network interfaces may employ connection protocols such as, but not limited to: direct connect, Ethernet (thick, thin, twisted pair 10/100/1000 Base T, and/or the like), Token Ring, wireless connection such as IEEE 802.11a-x, and/or the like. Should processing requirements dictate a greater amount speed and/or capacity, distributed network controllers (e.g., Distributed UEP), architectures may similarly be employed to pool, load balance, and/or otherwise increase the communicative bandwidth required by the UEP controller. A communications network may be any one and/or the combination of the following: a direct interconnection; the Internet; a Local Area Network (LAN); a Metropolitan Area Network (MAN); an Operating Missions as Nodes on the Internet (OMNI); a secured custom connection; a Wide Area Network (WAN); a wireless network (e.g., employing protocols such as, but not limited to a Wireless Application Protocol (WAP), I-mode, and/or the like); and/or the like. A network interface may be regarded as a specialized form of an input output interface. Further, multiple network interfaces  6110  may be used to engage with various communications network types  6113 . For example, multiple network interfaces may be employed to allow for the communication over broadcast, multicast, and/or unicast networks. 
     Input Output interfaces (I/O)  6108  may accept, communicate, and/or connect to user input devices  6111 , peripheral devices  6112 , cryptographic processor devices  6128 , and/or the like. I/O may employ connection protocols such as, but not limited to: audio: analog, digital, monaural, RCA, stereo, and/or the like; data: Apple Desktop Bus (ADB), IEEE 1394a-b, serial, universal serial bus (USB); infrared; joystick; keyboard; midi; optical; PC AT; PS/2; parallel; radio; video interface: Apple Desktop Connector (ADC), BNC, coaxial, component, composite, digital, Digital Visual Interface (DVI), high-definition multimedia interface (HDMI), RCA, RF antennae, S-Video, VGA, and/or the like; wireless transceivers: 802.11a/b/g/n/x; Bluetooth; cellular (e.g., code division multiple access (CDMA), high speed packet access (HSPA(+)), high-speed downlink packet access (HSDPA), global system for mobile communications (GSM), long term evolution (LTE), WiMax, etc.); and/or the like. One typical output device may include a video display, which typically comprises a Cathode Ray Tube (CRT) or Liquid Crystal Display (LCD) based monitor with an interface (e.g., DVI circuitry and cable) that accepts signals from a video interface, may be used. The video interface composites information generated by a computer systemization and generates video signals based on the composited information in a video memory frame. Another output device is a television set, which accepts signals from a video interface. Typically, the video interface provides the composited video information through a video connection interface that accepts a video display interface (e.g., an RCA composite video connector accepting an RCA composite video cable; a DVI connector accepting a DVI display cable, etc.). 
     User input devices  6111  often are a type of peripheral device  6112  (see below) and may include: card readers, dongles, finger print readers, gloves, graphics tablets, joysticks, keyboards, microphones, mouse (mice), remote controls, retina readers, touch screens (e.g., capacitive, resistive, etc.), trackballs, trackpads, sensors (e.g., accelerometers, ambient light, GPS, gyroscopes, proximity, etc.), styluses, and/or the like. 
     Peripheral devices  6112  may be connected and/or communicate to I/O and/or other facilities of the like such as network interfaces, storage interfaces, directly to the interface bus, system bus, the CPU, and/or the like. Peripheral devices may be external, internal and/or part of the UEP controller. Peripheral devices may include: antenna, audio devices (e.g., line-in, line-out, microphone input, speakers, etc.), cameras (e.g., still, video, webcam, etc.), dongles (e.g., for copy protection, ensuring secure transactions with a digital signature, and/or the like), external processors (for added capabilities; e.g., crypto devices  6128 ), force-feedback devices (e.g., vibrating motors), network interfaces, printers, scanners, storage devices, transceivers (e.g., cellular, GPS, etc.), video devices (e.g., goggles, monitors, etc.), video sources, visors, and/or the like. Peripheral devices often include types of input devices (e.g., cameras). 
     It should be noted that although user input devices and peripheral devices may be employed, the UEP controller may be embodied as an embedded, dedicated, and/or monitor-less (i.e., headless) device, wherein access would be provided over a network interface connection. 
     Cryptographic units such as, but not limited to, microcontrollers, processors  6126 , interfaces  6127 , and/or devices  6128  may be attached, and/or communicate with the UEP controller. A MC68HC16 microcontroller, manufactured by Motorola Inc., may be used for and/or within cryptographic units. The MC68HC16 microcontroller utilizes a 16-bit multiply-and-accumulate instruction in the 16 MHz configuration and requires less than one second to perform a 512-bit RSA private key operation. Cryptographic units support the authentication of communications from interacting agents, as well as allowing for anonymous transactions. Cryptographic units may also be configured as part of the CPU. Equivalent microcontrollers and/or processors may also be used. Other commercially available specialized cryptographic processors include: the Broadcom&#39;s CryptoNetX and other Security Processors; nCipher&#39;s nShield, SafeNet&#39;s Luna PCI (e.g., 7100) series; Semaphore Communications&#39; 40 MHz Roadrunner 184; Sun&#39;s Cryptographic Accelerators (e.g., Accelerator 6000 PCIe Board, Accelerator 500 Daughtercard); Via Nano Processor (e.g., L2100, L2200, U2400) line, which is capable of performing 500+MB/s of cryptographic instructions; VLSI Technology&#39;s 33 MHz  6868 ; and/or the like. 
     Memory 
     Generally, any mechanization and/or embodiment allowing a processor to affect the storage and/or retrieval of information is regarded as memory  6129 . However, memory is a fungible technology and resource, thus, any number of memory embodiments may be employed in lieu of or in concert with one another. It is to be understood that the UEP controller and/or a computer systemization may employ various forms of memory  6129 . For example, a computer systemization may be configured wherein the operation of on-chip CPU memory (e.g., registers), RAM, ROM, and any other storage devices are provided by a paper punch tape or paper punch card mechanism; however, such an embodiment would result in an extremely slow rate of operation. In a typical configuration, memory  6129  will include ROM  6106 , RAM  6105 , and a storage device  6114 . A storage device  6114  may be any conventional computer system storage. Storage devices may include a drum; a (fixed and/or removable) magnetic disk drive; a magneto-optical drive; an optical drive (i.e., Blueray, CD ROM/RAM/Recordable (R)/ReWritable (RW), DVD R/RW, HD DVD R/RW etc.); an array of devices (e.g., Redundant Array of Independent Disks (RAID)); solid state memory devices (USB memory, solid state drives (SSD), etc.); other processor-readable storage mediums; and/or other devices of the like. Thus, a computer systemization generally requires and makes use of memory. 
     Component Collection 
     The memory  6129  may contain a collection of program and/or database components and/or data such as, but not limited to: operating system component(s)  6115  (operating system); information server component(s)  6116  (information server); user interface component(s)  6117  (user interface); Web browser component(s)  6118  (Web browser); database(s)  6119 ; mail server component(s)  6121 ; mail client component(s)  6122 ; cryptographic server component(s)  6120  (cryptographic server); the UEP component(s)  6135 ; and/or the like (i.e., collectively a component collection). These components may be stored and accessed from the storage devices and/or from storage devices accessible through an interface bus. Although non-conventional program components such as those in the component collection, typically, are stored in a local storage device  6114 , they may also be loaded and/or stored in memory such as: peripheral devices, RAM, remote storage facilities through a communications network, ROM, various forms of memory, and/or the like. 
     Operating System 
     The operating system component  6115  is an executable program component facilitating the operation of the UEP controller. Typically, the operating system facilitates access of I/O, network interfaces, peripheral devices, storage devices, and/or the like. The operating system may be a highly fault tolerant, scalable, and secure system such as: Apple Macintosh OS X (Server); AT&amp;T Plan 9; Be OS; Unix and Unix-like system distributions (such as AT&amp;T&#39;s UNIX; Berkley Software Distribution (BSD) variations such as FreeBSD, NetBSD, OpenBSD, and/or the like; Linux distributions such as Red Hat, Ubuntu, and/or the like); and/or the like operating systems. However, more limited and/or less secure operating systems also may be employed such as Apple Macintosh OS, IBM OS/2, Microsoft DOS, Microsoft Windows 2000/2003/3.1/95/98/CE/Millenium/NT/Vista/XP (Server), Palm OS, and/or the like. An operating system may communicate to and/or with other components in a component collection, including itself, and/or the like. Most frequently, the operating system communicates with other program components, user interfaces, and/or the like. For example, the operating system may contain, communicate, generate, obtain, and/or provide program component, system, user, and/or data communications, requests, and/or responses. The operating system, once executed by the CPU, may enable the interaction with communications networks, data, I/O, peripheral devices, program components, memory, user input devices, and/or the like. The operating system may provide communications protocols that allow the UEP controller to communicate with other entities through a communications network  6113 . Various communication protocols may be used by the UEP controller as a subcarrier transport mechanism for interaction, such as, but not limited to: multicast, TCP/IP, UDP, unicast, and/or the like. 
     Information Server 
     An information server component  6116  is a stored program component that is executed by a CPU. The information server may be a conventional Internet information server such as, but not limited to Apache Software Foundation&#39;s Apache, Microsoft&#39;s Internet Information Server, and/or the like. The information server may allow for the execution of program components through facilities such as Active Server Page (ASP), ActiveX, (ANSI) (Objective-) C (++), C# and/or .NET, Common Gateway Interface (CGI) scripts, dynamic (D) hypertext markup language (HTML), FLASH, Java, JavaScript, Practical Extraction Report Language (PERL), Hypertext Pre-Processor (PHP), pipes, Python, wireless application protocol (WAP), WebObjects, and/or the like. The information server may support secure communications protocols such as, but not limited to, File Transfer Protocol (FTP); HyperText Transfer Protocol (HTTP); Secure Hypertext Transfer Protocol (HTTPS), Secure Socket Layer (SSL), messaging protocols (e.g., America Online (AOL) Instant Messenger (AIM), Application Exchange (APEX), ICQ, Internet Relay Chat (IRC), Microsoft Network (MSN) Messenger Service, Presence and Instant Messaging Protocol (PRIM), Internet Engineering Task Force&#39;s (IETF&#39;s) Session Initiation Protocol (SIP), SIP for Instant Messaging and Presence Leveraging Extensions (SIMPLE), open XML-based Extensible Messaging and Presence Protocol (XMPP) (i.e., Jabber or Open Mobile Alliance&#39;s (OMA&#39;s) Instant Messaging and Presence Service (IMPS)), Yahoo! Instant Messenger Service, and/or the like. The information server provides results in the form of Web pages to Web browsers, and allows for the manipulated generation of the Web pages through interaction with other program components. After a Domain Name System (DNS) resolution portion of an HTTP request is resolved to a particular information server, the information server resolves requests for information at specified locations on the UEP controller based on the remainder of the HTTP request. For example, a request such as http://123.124.125.126/myInformation.html might have the IP portion of the request “123.124.125.126” resolved by a DNS server to an information server at that IP address; that information server might in turn further parse the http request for the “/myInformation.html” portion of the request and resolve it to a location in memory containing the information “myInformation.html.” Additionally, other information serving protocols may be employed across various ports, e.g., FTP communications across port  21 , and/or the like. An information server may communicate to and/or with other components in a component collection, including itself, and/or facilities of the like. Most frequently, the information server communicates with the UEP database  6119 , operating systems, other program components, user interfaces, Web browsers, and/or the like. 
     Access to the UEP database may be achieved through a number of database bridge mechanisms such as through scripting languages as enumerated below (e.g., CGI) and through inter-application communication channels as enumerated below (e.g., CORBA, WebObjects, etc.). Any data requests through a Web browser are parsed through the bridge mechanism into appropriate grammars as required by the UEP. In one embodiment, the information server would provide a Web form accessible by a Web browser. Entries made into supplied fields in the Web form are tagged as having been entered into the particular fields, and parsed as such. The entered terms are then passed along with the field tags, which act to instruct the parser to generate queries directed to appropriate tables and/or fields. In one embodiment, the parser may generate queries in standard SQL by instantiating a search string with the proper join/select commands based on the tagged text entries, wherein the resulting command is provided over the bridge mechanism to the UEP as a query. Upon generating query results from the query, the results are passed over the bridge mechanism, and may be parsed for formatting and generation of a new results Web page by the bridge mechanism. Such a new results Web page is then provided to the information server, which may supply it to the requesting Web browser. 
     Also, an information server may contain, communicate, generate, obtain, and/or provide program component, system, user, and/or data communications, requests, and/or responses. 
     User Interface 
     Computer interfaces in some respects are similar to automobile operation interfaces. Automobile operation interface elements such as steering wheels, gearshifts, and speedometers facilitate the access, operation, and display of automobile resources, and status. Computer interaction interface elements such as check boxes, cursors, menus, scrollers, and windows (collectively and commonly referred to as widgets) similarly facilitate the access, capabilities, operation, and display of data and computer hardware and operating system resources, and status. Operation interfaces are commonly called user interfaces. Graphical user interfaces (GUIs) such as the Apple Macintosh Operating System&#39;s Aqua, IBM&#39;s OS/2, Microsoft&#39;s Windows 2000/2003/3.1/95/98/CE/Millenium/NT/XP/Vista/7 (i.e., Aero), Unix&#39;s X-Windows (e.g., which may include additional Unix graphic interface libraries and layers such as K Desktop Environment (KDE), mythTV and GNU Network Object Model Environment (GNOME)), web interface libraries (e.g., ActiveX, AJAX, (D)HTML, FLASH, Java, JavaScript, etc. interface libraries such as, but not limited to, Dojo, jQuery(UI), MooTools, Prototype, script.aculo.us, SWFObject, Yahoo! User Interface, any of which may be used and) provide a baseline and means of accessing and displaying information graphically to users. 
     A user interface component  6117  is a stored program component that is executed by a CPU. The user interface may be a conventional graphic user interface as provided by, with, and/or atop operating systems and/or operating environments such as already discussed. The user interface may allow for the display, execution, interaction, manipulation, and/or operation of program components and/or system facilities through textual and/or graphical facilities. The user interface provides a facility through which users may affect, interact, and/or operate a computer system. A user interface may communicate to and/or with other components in a component collection, including itself, and/or facilities of the like. Most frequently, the user interface communicates with operating systems, other program components, and/or the like. The user interface may contain, communicate, generate, obtain, and/or provide program component, system, user, and/or data communications, requests, and/or responses. 
     Web Browser 
     A Web browser component  6118  is a stored program component that is executed by a CPU. The Web browser may be a conventional hypertext viewing application such as Microsoft Internet Explorer or Netscape Navigator. Secure Web browsing may be supplied with 128 bit (or greater) encryption by way of HTTPS, SSL, and/or the like. Web browsers allowing for the execution of program components through facilities such as ActiveX, AJAX, (D)HTML, FLASH, Java, JavaScript, web browser plug-in APIs (e.g., FireFox, Safari Plug-in, and/or the like APIs), and/or the like. Web browsers and like information access tools may be integrated into PDAs, cellular telephones, and/or other mobile devices. A Web browser may communicate to and/or with other components in a component collection, including itself, and/or facilities of the like. Most frequently, the Web browser communicates with information servers, operating systems, integrated program components (e.g., plug-ins), and/or the like; e.g., it may contain, communicate, generate, obtain, and/or provide program component, system, user, and/or data communications, requests, and/or responses. Also, in place of a Web browser and information server, a combined application may be developed to perform similar operations of both. The combined application would similarly affect the obtaining and the provision of information to users, user agents, and/or the like from the UEP enabled nodes. The combined application may be nugatory on systems employing standard Web browsers. 
     Mail Server 
     A mail server component  6121  is a stored program component that is executed by a CPU  6103 . The mail server may be a conventional Internet mail server such as, but not limited to sendmail, Microsoft Exchange, and/or the like. The mail server may allow for the execution of program components through facilities such as ASP, ActiveX, (ANSI) (Objective-) C (++), C# and/or .NET, CGI scripts, Java, JavaScript, PERL, PHP, pipes, Python, WebObjects, and/or the like. The mail server may support communications protocols such as, but not limited to: Internet message access protocol (IMAP), Messaging Application Programming Interface (MAPI)/Microsoft Exchange, post office protocol (POP3), simple mail transfer protocol (SMTP), and/or the like. The mail server can route, forward, and process incoming and outgoing mail messages that have been sent, relayed and/or otherwise traversing through and/or to the UEP. 
     Access to the UEP mail may be achieved through a number of APIs offered by the individual Web server components and/or the operating system. 
     Also, a mail server may contain, communicate, generate, obtain, and/or provide program component, system, user, and/or data communications, requests, information, and/or responses. 
     Mail Client 
     A mail client component  6122  is a stored program component that is executed by a CPU  6103 . The mail client may be a conventional mail viewing application such as Apple Mail, Microsoft Entourage, Microsoft Outlook, Microsoft Outlook Express, Mozilla, Thunderbird, and/or the like. Mail clients may support a number of transfer protocols, such as: IMAP, Microsoft Exchange, POP3, SMTP, and/or the like. A mail client may communicate to and/or with other components in a component collection, including itself, and/or facilities of the like. Most frequently, the mail client communicates with mail servers, operating systems, other mail clients, and/or the like; e.g., it may contain, communicate, generate, obtain, and/or provide program component, system, user, and/or data communications, requests, information, and/or responses. Generally, the mail client provides a facility to compose and transmit electronic mail messages. 
     Cryptographic Server 
     A cryptographic server component  6120  is a stored program component that is executed by a CPU  6103 , cryptographic processor  6126 , cryptographic processor interface  6127 , cryptographic processor device  6128 , and/or the like. Cryptographic processor interfaces will allow for expedition of encryption and/or decryption requests by the cryptographic component; however, the cryptographic component, alternatively, may run on a conventional CPU. The cryptographic component allows for the encryption and/or decryption of provided data. The cryptographic component allows for both symmetric and asymmetric (e.g., Pretty Good Protection (PGP)) encryption and/or decryption. The cryptographic component may employ cryptographic techniques such as, but not limited to: digital certificates (e.g., X.509 authentication framework), digital signatures, dual signatures, enveloping, password access protection, public key management, and/or the like. The cryptographic component will facilitate numerous (encryption and/or decryption) security protocols such as, but not limited to: checksum, Data Encryption Standard (DES), Elliptical Curve Encryption (ECC), International Data Encryption Algorithm (IDEA), Message Digest 5 (MD5, which is a one way hash operation), passwords, Rivest Cipher (RCS), Rijndael, RSA (which is an Internet encryption and authentication system that uses an algorithm developed in 1977 by Ron Rivest, Adi Shamir, and Leonard Adleman), Secure Hash Algorithm (SHA), Secure Socket Layer (SSL), Secure Hypertext Transfer Protocol (HTTPS), and/or the like. Employing such encryption security protocols, the UEP may encrypt all incoming and/or outgoing communications and may serve as node within a virtual private network (VPN) with a wider communications network. The cryptographic component facilitates the process of “security authorization” whereby access to a resource is inhibited by a security protocol wherein the cryptographic component effects authorized access to the secured resource. In addition, the cryptographic component may provide unique identifiers of content, e.g., employing and MD5 hash to obtain a unique signature for an digital audio file. A cryptographic component may communicate to and/or with other components in a component collection, including itself, and/or facilities of the like. The cryptographic component supports encryption schemes allowing for the secure transmission of information across a communications network to enable the UEP component to engage in secure transactions if so desired. The cryptographic component facilitates the secure accessing of resources on the UEP and facilitates the access of secured resources on remote systems; i.e., it may act as a client and/or server of secured resources. Most frequently, the cryptographic component communicates with information servers, operating systems, other program components, and/or the like. The cryptographic component may contain, communicate, generate, obtain, and/or provide program component, system, user, and/or data communications, requests, and/or responses. 
     The UEP Database 
     The UEP database component  6119  may be embodied in a database and its stored data. The database is a stored program component, which is executed by the CPU; the stored program component portion configuring the CPU to process the stored data. The database may be a conventional, fault tolerant, relational, scalable, secure database such as Oracle or Sybase. Relational databases are an extension of a flat file. Relational databases consist of a series of related tables. The tables are interconnected via a key field. Use of the key field allows the combination of the tables by indexing against the key field; i.e., the key fields act as dimensional pivot points for combining information from various tables. Relationships generally identify links maintained between tables by matching primary keys. Primary keys represent fields that uniquely identify the rows of a table in a relational database. More precisely, they uniquely identify rows of a table on the “one” side of a one-to-many relationship. 
     Alternatively, the UEP database may be implemented using various standard data-structures, such as an array, hash, (linked) list, struct, structured text file (e.g., XML), table, and/or the like. Such data-structures may be stored in memory and/or in (structured) files. In another alternative, an object-oriented database may be used, such as Frontier, ObjectStore, Poet, Zope, and/or the like. Object databases can include a number of object collections that are grouped and/or linked together by common attributes; they may be related to other object collections by some common attributes. Object-oriented databases perform similarly to relational databases with the exception that objects are not just pieces of data but may have other types of capabilities encapsulated within a given object. If the UEP database is implemented as a data-structure, the use of the UEP database  6119  may be integrated into another component such as the UEP component  6135 . Also, the database may be implemented as a mix of data structures, objects, and relational structures. Databases may be consolidated and/or distributed in countless variations through standard data processing techniques. Portions of databases, e.g., tables, may be exported and/or imported and thus decentralized and/or integrated. 
     In one embodiment, the database component  6119  includes several tables  6119   a - o . A Users table  6119   a  may include fields such as, but not limited to: user_id, ssn, dob, first_name, last_name, age, state, address_firstline, address_secondline, zipcode, devices_list, contact_info, contact_type, alt_contact_info, alt_contact_type, and/or the like. The Users table may support and/or track multiple entity accounts on a UEP. A Devices table  6119   b  may include fields such as, but not limited to: device_ID, device_name, device_IP, device_MAC, device_type, device_model, device_version, device_OS, device_apps_list, device_securekey, wallet_app_installed_flag, and/or the like. An Apps table  6119   c  may include fields such as, but not limited to: app_ID, app_name, app_type, app_dependencies, and/or the like.

An Acquirers table  6119   g  may include fields such as, but not limited to: account_firstname, account_lastname, account_type, account_num, account_balance_list, billingaddress_line1, billingaddress_line2, billing_zipcode, billing_state, shipping_preferences, shippingaddress_line1, shippingaddress_line2, shipping_zipcode, shipping_state, and/or the like. A Pay Gateways table  6119   h  may include fields such as, but not limited to: gateway_ID, gateway_IP, gateway_MAC, gateway_secure_key, gateway_access_list, gateway_API_call_list, gateway_services_list, and/or the like. A Transactions table  6119   i  may include fields such as, but not limited to: order_id, user_id, timestamp, transaction_cost, purchase_details_list, num_products, products_list, product_type, product_params_list, product_title, product_summary, quantity, user_id, client_id, client_ip, client_type, client_model, operating_system, os_version, app_installed_flag, user_id, account_firstname, account_lastname, account_type, account_num, account_priority_account_ratio, billingaddress_line1, billingaddress_line2, billing_zipcode, billing_state, shipping_preferences, shippingaddress_line1, shippingaddress_line2, shipping_zipcode, shipping_state, merchant_id, merchant_name, merchant auth_key, and/or the like. A Batches table  6119   j  may include fields such as, but not limited to: batch_id, transaction_id_list, timestamp_list, cleared_flag_list, clearance trigger settings, and/or the like.

An Offers table  6119   m  may include fields such as, but not limited to: offer_ID, offer_title, offer_attributes_list, offer_price, offer_expiry, related_products_list, discounts_list, rewards_list, merchants_list, merchant_availability_list, and/or the like. A Behavior Data table  6119   n  may include fields such as, but not limited to: user_id, timestamp, activity_type, activity_location, activity_attribute_list, activity_attribute_values_list, and/or the like. An Analytics table  61190  may include fields such as, but not limited to: report_id, user_id, report_type, report_algorithm_id, report_destination_address, and/or the like. A Market Data table  6119   p  may include fields such as, but not limited to: market_data_feed_ID, asset_ID, asset_symbol, asset_name, spot_price, bid_price, ask_price, and/or the like; in one embodiment, the market data table is populated through a market data feed (e.g., Bloomberg&#39;s PhatPipe, Dun &amp; Bradstreet, Reuter&#39;s Tib, Triarch, etc.), for example, through Microsoft&#39;s Active Template Library and Dealing Object Technology&#39;s real-time toolkit Rtt.Multi. 
     In one embodiment, the UEP database may interact with other database systems. For example, employing a distributed database system, queries and data access by search UEP component may treat the combination of the UEP database, an integrated data security layer database as a single database entity. 
     In one embodiment, user programs may contain various user interface primitives, which may serve to update the UEP. Also, various accounts may require custom database tables depending upon the environments and the types of clients the UEP may need to serve. It should be noted that any unique fields may be designated as a key field throughout. In an alternative embodiment, these tables have been decentralized into their own databases and their respective database controllers (i.e., individual database controllers for each of the above tables). Employing standard data processing techniques, one may further distribute the databases over several computer systemizations and/or storage devices. Similarly, configurations of the decentralized database controllers may be varied by consolidating and/or distributing the various database components  6119   a - o . The UEP may be configured to keep track of various settings, inputs, and parameters via database controllers. 
     The UEP database may communicate to and/or with other components in a component collection, including itself, and/or facilities of the like. Most frequently, the UEP database communicates with the UEP component, other program components, and/or the like. The database may contain, retain, and provide information regarding other nodes and data. 
     The UEPs 
     The UEP component  6135  is a stored program component that is executed by a CPU. In one embodiment, the UEP component incorporates any and/or all combinations of the aspects of the UEP discussed in the previous figures. As such, the UEP affects accessing, obtaining and the provision of information, services, transactions, and/or the like across various communications networks. 
     The UEP component may transform touchscreen inputs into a virtual wallet mobile application interface via UEP components into purchase transaction triggers and receipt notices, and/or the like and use of the UEP. In one embodiment, the UEP component  6135  takes inputs (e.g., checkout request  5511 ; product data  5515 ; wallet access input  5711 ; transaction authorization input  5714 ; payment gateway address  5718 ; payment network address  5722 ; issuer server address(es)  5725 ; funds authorization request(s)  5726 ; user(s) account(s) data  5728 ; batch data  5912 ; payment network address  5916 ; issuer server address(es)  5924 ; individual payment request  5925 ; payment ledger, merchant account data  5931 ; and/or the like) etc., and transforms the inputs via various components (e.g., UPC  6141 ; PTA  6142 ; PTC  6143 ; STG  6144 ; EPGU  6145 ; EAA  6146 ; CEC  6147 ; ETC  6148 ; DFR  6149 ; ADRN  6150 ; VASE  6151 ; SDA  6152 ; TDA  6153 ; CTDA  6154 ; SRA  6155 ; UBA  6156 ; UBOR  6157 ; SPE  6158 ; SPT  6159 ; WSS  6160 ; SMCB  6161 ; VWSC  6162 ; ORE  6163 ; QRCP  6164 ; SMPE  6165 ; PCS  6166 ; UST  6167 ; STRS  6168 ; USTG  6169 ; and/or the like), into outputs (e.g., checkout request message  5513 ; checkout data  5517 ; card authorization request  5716 ,  5723 ; funds authorization response(s)  5730 ; transaction authorization response  5732 ; batch append data  5734 ; purchase receipt  5735 ; batch clearance request  5914 ; batch payment request  5918 ; transaction data  5920 ; individual payment confirmation  5928 ,  5929 ; updated payment ledger, merchant account data  5933 ; and/or the like). 
     The UEP component enabling access of information between nodes may be developed by employing standard development tools and languages such as, but not limited to: Apache components, Assembly, ActiveX, binary executables, (ANSI) (Objective-) C (++), C# and/or .NET, database adapters, CGI scripts, Java, JavaScript, mapping tools, procedural and object oriented development tools, PERL, PHP, Python, shell scripts, SQL commands, web application server extensions, web development environments and libraries (e.g., Microsoft&#39;s ActiveX; Adobe AIR, FLEX &amp; FLASH; AJAX; (D)HTML; Dojo, Java; JavaScript; jQuery(UI); MooTools; Prototype; script.aculo.us; Simple Object Access Protocol (SOAP); SWFObject; Yahoo! User Interface; and/or the like), WebObjects, and/or the like. In one embodiment, the UEP server employs a cryptographic server to encrypt and decrypt communications. The UEP component may communicate to and/or with other components in a component collection, including itself, and/or facilities of the like. Most frequently, the UEP component communicates with the UEP database, operating systems, other program components, and/or the like. The UEP may contain, communicate, generate, obtain, and/or provide program component, system, user, and/or data communications, requests, and/or responses. 
     Distributed UEPs 
     The structure and/or operation of any of the UEP node controller components may be combined, consolidated, and/or distributed in any number of ways to facilitate development and/or deployment. Similarly, the component collection may be combined in any number of ways to facilitate deployment and/or development. To accomplish this, one may integrate the components into a common code base or in a facility that can dynamically load the components on demand in an integrated fashion. 
     The component collection may be consolidated and/or distributed in countless variations through standard data processing and/or development techniques. Multiple instances of any one of the program components in the program component collection may be instantiated on a single node, and/or across numerous nodes to improve performance through load-balancing and/or data-processing techniques. Furthermore, single instances may also be distributed across multiple controllers and/or storage devices; e.g., databases. All program component instances and controllers working in concert may do so through standard data processing communication techniques. 
     The configuration of the UEP controller will depend on the context of system deployment. Factors such as, but not limited to, the budget, capacity, location, and/or use of the underlying hardware resources may affect deployment requirements and configuration. Regardless of if the configuration results in more consolidated and/or integrated program components, results in a more distributed series of program components, and/or results in some combination between a consolidated and distributed configuration, data may be communicated, obtained, and/or provided. Instances of components consolidated into a common code base from the program component collection may communicate, obtain, and/or provide data. This may be accomplished through intra-application data processing communication techniques such as, but not limited to: data referencing (e.g., pointers), internal messaging, object instance variable communication, shared memory space, variable passing, and/or the like. 
     If component collection components are discrete, separate, and/or external to one another, then communicating, obtaining, and/or providing data with and/or to other components may be accomplished through inter-application data processing communication techniques such as, but not limited to: Application Program Interfaces (API) information passage; (distributed) Component Object Model ((D)COM), (Distributed) Object Linking and Embedding ((D)OLE), and/or the like), Common Object Request Broker Architecture (CORBA), Jini local and remote application program interfaces, JavaScript Object Notation (JSON), Remote Method Invocation (RMI), SOAP, process pipes, shared files, and/or the like. Messages sent between discrete component components for inter-application communication or within memory spaces of a singular component for intra-application communication may be facilitated through the creation and parsing of a grammar. A grammar may be developed by using development tools such as lex, yacc, XML, and/or the like, which allow for grammar generation and parsing capabilities, which in turn may form the basis of communication messages within and between components. 
     For example, a grammar may be arranged to recognize the tokens of an HTTP post command, e.g.:
         w3c-post http:// . . . Value1       

     where Value1 is discerned as being a parameter because “http://” is part of the grammar syntax, and what follows is considered part of the post value. Similarly, with such a grammar, a variable “Value1” may be inserted into an “http://” post command and then sent. The grammar syntax itself may be presented as structured data that is interpreted and/or otherwise used to generate the parsing mechanism (e.g., a syntax description text file as processed by lex, yacc, etc.). Also, once the parsing mechanism is generated and/or instantiated, it itself may process and/or parse structured data such as, but not limited to: character (e.g., tab) delineated text, HTML, structured text streams, XML, and/or the like structured data. In another embodiment, inter-application data processing protocols themselves may have integrated and/or readily available parsers (e.g., JSON, SOAP, and/or like parsers) that may be employed to parse (e.g., communications) data. Further, the parsing grammar may be used beyond message parsing, but may also be used to parse: databases, data collections, data stores, structured data, and/or the like. Again, the desired configuration will depend upon the context, environment, and requirements of system deployment. 
     For example, in some implementations, the UEP controller may be executing a PHP script implementing a Secure Sockets Layer (“SSL”) socket server via the information server, which listens to incoming communications on a server port to which a client may send data, e.g., data encoded in JSON format. Upon identifying an incoming communication, the PHP script may read the incoming message from the client device, parse the received JSON-encoded text data to extract information from the JSON-encoded text data into PHP script variables, and store the data (e.g., client identifying information, etc.) and/or extracted information in a relational database accessible using the Structured Query Language (“SQL”). An exemplary listing, written substantially in the form of PHP/SQL commands, to accept JSON-encoded input data from a client device via a SSL connection, parse the data to extract variables, and store the data to a database, is provided below:

                 $address = ‘192.168.0.100’; 
               
               
                 $port = 255; 
               
               
                 // create a server-side SSL socket, listen for/accept incoming communication 
               
               
                 $sock = socket_create(AF_INET, SOCK_STREAM, 0); 
               
               
                 socket_bind($sock, $address, $port) or die(‘Could not bind to address&#39;); 
               
               
                 socket_listen($sock); 
               
               
                 $client = socket_accept($sock); 
               
               
                 // read input data from client device in 1024 byte blocks until end of message

                 $input = ““; 
               
               
                   
                 $input = socket_read($client, 1024);

     In order to address various issues and advance the art, the entirety of this application for UNIVERSAL ELECTRONIC PAYMENT APPARATUSES, METHODS AND SYSTEMS (including the Cover Page, Title, Headings, Field, Background, Summary, Brief Description of the Drawings, Detailed Description, Claims, Abstract, Figures, Appendices and/or otherwise) shows by way of illustration various embodiments in which the claimed innovations may be practiced. The advantages and features of the application are of a representative sample of embodiments only, and are not exhaustive and/or exclusive. They are presented only to assist in understanding and teach the claimed principles. It should be understood that they are not representative of all claimed innovations. As such, certain aspects of the disclosure have not been discussed herein. That alternate embodiments may not have been presented for a specific portion of the innovations or that further undescribed alternate embodiments may be available for a portion is not to be considered a disclaimer of those alternate embodiments. It will be appreciated that many of those undescribed embodiments incorporate the same principles of the innovations and others are equivalent. Thus, it is to be understood that other embodiments may be utilized and functional, logical, operational, organizational, structural and/or topological modifications may be made without departing from the scope and/or spirit of the disclosure. As such, all examples and/or embodiments are deemed to be non-limiting throughout this disclosure. Also, no inference should be drawn regarding those embodiments discussed herein relative to those not discussed herein other than it is as such for purposes of reducing space and repetition. For instance, it is to be understood that the logical and/or topological structure of any combination of any program components (a component collection), other components and/or any present feature sets as described in the figures and/or throughout are not limited to a fixed operating order and/or arrangement, but rather, any disclosed order is exemplary and all equivalents, regardless of order, are contemplated by the disclosure. Furthermore, it is to be understood that such features are not limited to serial execution, but rather, any number of threads, processes, services, servers, and/or the like that may execute asynchronously, concurrently, in parallel, simultaneously, synchronously, and/or the like are contemplated by the disclosure. As such, some of these features may be mutually contradictory, in that they cannot be simultaneously present in a single embodiment. Similarly, some features are applicable to one aspect of the innovations, and inapplicable to others. In addition, the disclosure includes other innovations not presently claimed. Applicant reserves all rights in those presently unclaimed innovations, including the right to claim such innovations, file additional applications, continuations, continuations in part, divisions, and/or the like thereof. As such, it should be understood that advantages, embodiments, examples, functional, features, logical, operational, organizational, structural, topological, and/or other aspects of the disclosure are not to be considered limitations on the disclosure as defined by the claims or limitations on equivalents to the claims. It is to be understood that, depending on the particular needs and/or characteristics of a UEP individual and/or enterprise user, database configuration and/or relational model, data type, data transmission and/or network framework, syntax structure, and/or the like, various embodiments of the UEP may be implemented that enable a great deal of flexibility and customization. For example, aspects of the UEP may be adapted for financial trading; operations security; resource management; and/or the like. While various embodiments and discussions of the UEP have been directed to electronic commerce, however, it is to be understood that the embodiments described herein may be readily configured and/or customized for a wide variety of other applications and/or implementations.
