Title: Method and system for consumer transactions using voice or human based gesture actions

Description:
RELATED APPLICATIONS 
     This application claims the priority benefit of commonly assigned U.S. Provisional Application No. 61/415,529, “Financial Card Method, Device and System Utilizing Bar Codes to Identify Transaction Details,” by Garry Lyons et al., filed Nov. 19, 2010; U.S. Provisional Application No. 61/479,134, “Financial Card Method, Device and System Utilizing Bar Codes to Identify Transaction Details,” by Garry Lyons et al., filed Apr. 26, 2011; and U.S. Provisional Application No. 61/534,832, “Method and System for Purchasing Products Advertised on Multi-Media Using Voice and/or Gesture-Based Commands,” by Alan Cooke et al., filed Sep. 14, 2011. The subject matter of all of the foregoing is herein incorporated by reference in its entirety. 
    
    
     FIELD 
     The present disclosure relates to electronic financial transactions, specifically through the use of voice or human based gesture actions. 
     BACKGROUND 
     There is market pressure for finding more convenient ways to reach out to consumers and to initiate a financial transaction with the consumer. There is also market pressure for finding more convenient ways to conduct financial transactions between individuals and businesses once a transaction has been initiated. 
     Consumers may be in situation where they are viewing internet- or television-based advertisements for a product they wish to purchase, but are not immediately able to do so. By the time the consumer is able to purchase the product, they may have forgotten the product they wished to buy or the merchant that was advertising. The consumer can also be at risk of making an incorrect purchase, such as choosing an incorrect model or brand of the product, or of paying too much or missing a special promotion by purchasing through a different merchant. Thus, there exists a need for a consumer to be able to quickly and easily initiate a financial transaction for the visually or multimedia advertised product. 
     SUMMARY 
     The present disclosure provides for a method and system of initiating a financial transaction through human voice and gesture based actions. 
     An exemplary method for initiating a consumer transaction includes transmitting video data from a processing device to a display device, monitoring the video for event data corresponding to a plurality of consumer products or services, receiving the event data in the processing device, and notifying a consumer on the display device of an eligible consumer transaction. The method further includes reading voice or human based gesture actions with a human interaction device, analyzing the voice or human based gesture actions, and initiating a consumer transaction for the plurality of consumer products or services if the voice or human based gesture actions conform to a predetermined set of requirements. 
     Another exemplary method includes transmitting video data from a processing device to a display device, monitoring for event data corresponding to a plurality of consumer products or services, receiving the event data in the processing device, and notifying a consumer on the display device of an eligible consumer transaction. Voice or human gesture based actions are read with a human interaction device and analyzed. If the voice or human gesture based actions conform to a predetermined set of interaction requirements, a machine-readable pay code in which transaction details for a specific transaction for the plurality of consumer products or services are encoded is transmitted to a payer device. The method further includes requesting the transaction details for the specific transaction from a pay code provider, receiving the transaction details on the payer device, and receiving indications of payer selected transaction options from a user of the payer device. The indications are transmitted to the pay code provider for conveyance to a payee, and an indication that completion of the transaction has been initiated by initiating payment from the payer to the payee is received. The payer device is a communications device enabled to read machine-readable code and specifically programmed to carry out the above transmitting, requesting, and receiving actions. 
     An exemplary system for initiating a consumer transaction includes a display device, a human interaction device configured to read and transmit voice or human based gesture actions, and a processing device. The processing device is configured to at least receive video data; transmit the video data to the display device, receive and analyze the voice or human based gesture actions, compare the voice or human based gesture actions with a predetermined set of requirements, and initiate a consumer transaction if the voice or human based gesture actions meet the predetermined first set of interaction requirements. The display device is also configured to receive the video data from the processing device and display the received video data. 
     Another exemplary system includes a payee, a pay code provider, a display device, a payer device, a human interaction device, and a processing device. The human interaction device is configured to read and transmit voice or human based gesture actions. The processing device is configured to at least receive video data; transmit the video data to the display device, receive and analyze the voice or human based gesture actions, compare the voice or human based gesture actions with a predetermined set of requirements, and transmit a machine-readable pay code in which transaction details for a specific transaction are encoded to the payer device if the voice or human based gesture actions meet the predetermined set of requirements. The display device is configured to receive the video data from the processing device and display the received video data. The payer device is configured to receive and read the machine-readable pay code, request the transaction details for the specific transaction from the pay code provider, and display the transaction details.

     Further areas of applicability of the present disclosure will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description of exemplary embodiments are intended for illustration purposes only and are, therefore, not intended to necessarily limit the scope of the disclosure. 
     DETAILED DESCRIPTION 
     Definitions of Terms 
     Pay Code Arrangement—A method and computer-implemented system specifically programmed to carry out the electronic financial transaction methods disclosed herein, in which a machine-readable representation of data may be generated with transaction details (e.g., a transaction identification) that can be read by a payer device as part of a financial transaction. 
     Financial Transaction Account—Credit card accounts, debit card accounts, hybrid card accounts, accounts with utilities or other credit providers, demand deposits, other revolving lines of credit, home equity loans, and/or nearly any other source of funds. 
     Payer—An individual, business, or other entity that wishes to transfer funds to a payee for reasons including, but not limited to, paying a debt, purchasing goods, services, and/or charitable contributions, among others. 
     Payee—An individual, business, or other entity that receives funds transferred from a payer for reasons including, but not limited to, paying a debt, purchasing goods, services, and/or other charitable contributions, among others. 
     Pay Code—A machine-readable code used to identify a transaction and which may identify other transaction details, including, but not limited to, identification of one or more of: (1) the quality associated with the transaction, (2) the quantity associated with the transaction, (3) the size associated with the transaction, (4) the color associated with the transaction, (5) shipping information associated with the transaction, (6) the identity of the payer associated with the transaction, (7) the payee or a third party associated with the transaction, and (8) the financial account identification or a pointer that can be used to identify an account (e.g., a financial account), or nearly any other information that might be relevant to the parties or the transaction. A portion of the transaction details may be provided as part of the machine-readable code (e.g., attached to a transaction product or associated with the transaction product or transaction service) and other transaction details may be added by the payer or other entities during processing of the transaction. 
     Transaction skeleton—basic details of the transaction without a transaction identifier (ID) that may be represented in a barcode or on the pay code server. When the transaction ID is assigned, the transaction details then include the details for completion of a transaction. 
     Payer Device—computing devices including but not limited to hand-held computing devices such as smart phones, table computers, PDAs, personal computers and network terminals, that have the ability to read machine-readable data and communicate with other computers and/or humans through an interface. 
     Exemplary Payer Device Implementations 
     Payer devices (e.g., payer device  10 B of  FIGS. 1A-1E ) can be nearly any type of device that has the ability to communicate with other computers and is capable of reading machine-readable representations of data, such as a bar code (e.g., QR code), RFID, acoustic signals or video signals, etc. Exemplary payer devices can include bar code scanners, personal digital assistants (PDAs) equipped with a camera, microphone or other sensing device, MP3 players equipped with a camera, microphone or other sensing device, cameras capable of communications with other computers, tablet computers and laptop computers with cameras, microphones, mobile telephones with a camera microphone, smart phones, etc. 
     Other types of readers can be used, such as smart phones that have been adapted to read RFID tags, and RFID readers with communication capabilities, for instance. In most instances, nearly any unique tag could be used, whether optical, radio frequency (RF), magnetic, video and/or even sound-based, particularly because each of these parameters (e.g., all of these physical parameters) can be measured on a current smart phone, such as the iPhone®. In some embodiments, an exemplary payer device may include a near field communication (NFC) chip, suitable for receiving data through near field communication. 
     Pay Code Implementations 
     In the present exemplary embodiments, the pay code may be a matrix barcode (or two-dimensional code) such as a QR code or other codes such as an EZcode, a high capacity color barcode, a ShotCode, a MaxiCode, a GTIN12 code and/or GTIN-13 code, etc. The matrix bar code may be readable by bar code scanners, mobile phones with a camera, and/or smart phones, for example. Exemplary QR codes may consist of black modules arranged in a square pattern on white background. The information encoded on the pay code can be text, a URL or other data. 
     Pay codes, in their most basic form, can include a transaction identifier (e.g., only a transaction identifier), although it is envisioned that many more details of the transaction may be encoded in the pay code. As such, a simple, one dimensional bar code may be used, but also any optical machine-readable representation of data could be used in conjunction with an optical imager (e.g., a camera) on a payer device. As yet another alternative, RF identification, or nearly any other machine-readable representation of data, could be used that might be presented to a payer device or an adaptor of the payer device. For example, optical machine-readable representations of data, which are currently available on most modern mobile phones equipped with a camera, may be used to capture and process the machine-readable representation of the data. 
     In some exemplary embodiments, a pay code may be used simultaneously with a near field communication (NFC) chip. A pay code that only includes a transaction identifier may be paired with a near field communication chip configured to transmit additional transaction information that a pay code may be unable to include (e.g., due to size limitations). As such, if a payer device is also equipped with a near field communication chip, when the payer device scans the pay code, it can also receive the additional transaction information from the paired NFC chip. The ability to obtain additional transaction information not included with the pay code can be beneficial at times when a pay code provider may be unavailable (e.g., when the payer device lacks a network connection). 
     Financial Transaction System Overview 
       FIG. 1A  is a block diagram illustrating a top level view of a financial transaction system according to various exemplary embodiments. 
     Referring to  FIG. 1A , most credit card transactions involve four basic participants, although many other participants can be involved. The four basic participants are a customer (e.g., payer or user)  10  who may pay with a financial transaction card, an issuer  20  that may issue the financial transaction card, a merchant  40  that may sell products or services (hereinafter “product” or “products”), and an acquirer  30  that may collect payment for the merchant  40 . In the present system, however, this terminology does not always apply. For instance, the merchant  40  may be another person to whom the purchaser is indebted. The purchaser may be someone who owes a debt, regardless of whether products or services are being purchased. The acquirer  30  may or may not be involved in certain transaction types. The present pay code arrangement may not involve the current financial transaction system, but is explained in the context of the current financial transaction system that has been modified to handle pay codes for ease of understanding. 
     As shown in  FIGS. 1A-1E , a pay code server (or barcode server)  50  may be added to a traditional financial transaction card system. The pay code server  50  may be a stand-alone application (or system) or embedded in the processing (operations) by the issuer  20 , the acquirer  30  or the merchant  40 . The payer  10  may have a payer device  10 A or  10 B, such as a smart phone or mobile computer, among others as more fully explained herein. 
       FIGS. 1B-1E  illustrate a graphical user interface (GUI) of a payer device  10 A or  10 B for performing a financial transaction in accordance with the system of  FIG. 1A . 
     A payer  10  may visit a restaurant or other eating establishment (e.g., the merchant  20 ) and may use their payer device  10 A or  10 B to place their order.  FIG. 1B  illustrates a GUI on the payer device  10 A, including a menu screen  110  that offers a plurality of menu item selections  102 A- 102 G. The payer  10  may select any number of the menu items  102 A- 102 G.  FIG. 1C  illustrates a checkout screen  120 , that prompts the payer to place an order after selecting menu items  102 A and  102 C. The menu items  102 A and  102 C may provide additional details (e.g., quantity, type, etc.) for each item. The checkout screen  120  may also identify the payee  103  (e.g., the merchant  120 ). The payer  10  may select the payment method  104 , for which the payer  10  wishes to pay for the transaction. The payment amount  105  may also be shown on the checkout screen  120 . The payer  10  may initiate payment of the transaction by selecting the “pay now” button  106 . 
     Upon initiating payment, the payer  10  may be presented with the details screen  130  on the payer device  10 A, as illustrated in  FIG. 1D . The details screen  130  may include, for example, information relating to the payer  103 , the payment method  104 , and the payment amount  105 . The details screen  130  may also provide the payer  10  with a list of all of the purchase menu items (e.g., menu items  102 A and  102 C). A machine-readable barcode  107  may also be provided as part of the details screen  130 . The machine-readable barcode  107  may be encoded with transaction information (e.g., a transaction ID, menu items, quantities of items, etc.). The merchant  120  may use a device, such as a payer device  10 B, to read the machine-readable barcode  107  and obtain the transaction information. In one embodiment, the merchant  120  may read the machine-readable barcode  107  and decode the transaction information, which may be transmitted to or optically read at the merchant&#39;s point of sale (POS) system for automatic entry of the order and/or payment information. 
     In one embodiment, the payer  10  may select from one of the menu items (e.g., menu item  102 C) from the details screen  130 . Upon selection of the menu item, the payer  10  may be presented with a sharing prompt  108 , as illustrated in  FIG. 1E . The sharing prompt  108  may provide the payer  10  with options for sharing information about their purchase with others (e.g., on a social network, reimbursement/accounting software or services, day planner/journal/diary/and/or dietary/purchase tracking software or service, etc.). 
     Basic Pay Code Transactions 
       FIGS. 2A and 2B  are a flow diagram illustrating an exemplary basic pay code flow. 
     As shown in  FIGS. 2A and 2B , three entities may be involved in basic pay code transactions including the merchant  40 , the pay code server  50  and the payer device  10 A controlled by the payer  10 . At block  202 , the basic transaction details may be built (e.g., generated by the merchant  40 ). At block  204 , the merchant  40  may send (e.g., communicate) the transaction details to the pay code server  50 . At block  206 , the transaction details may be received in (by) the pay code server  50  and, at block  208 , the pay code server  50  may create an electronic record of the transaction. At block  210 , the pay code server  50  may send (e.g., return) the pay code to the merchant  40 . The pay code (e.g., a QR code) may include data such as a transaction ID, and/or other details (e.g., optional transaction details). The data (e.g., the only data) that may be required for the pay code is a transaction ID. Additional transaction details, information about the parties (or the transaction), financial accounts, and/or restrictions (e.g., policies on the use of the pay code or pricing, sales terms of the good or service associated with pay code, etc.), among others could be included together with the transaction ID for a particular pay code. For example, the transaction details may include: (1) one or more transaction descriptions (e.g., identity, quantity, payment terms, payment amount, merchant ID, merchant category, merchant code, etc.); (2) an expiration (e.g., a time in which the transaction should transpire to be valid); (3) a recipient or a sender; and/or (4) other clarifying information as is appropriate to a given circumstance, among others. 
     At block  212 , the merchant  40  may receive the pay code data and may electronically generate and then may display the pay code data (e.g., present or otherwise makes the pay code available, such as on a bill) to the payer device  10 A. In certain exemplary embodiments, when using an optical pay code reader, the pay code may be displayed on a screen or printed on paper, for example. 
     At block  214 , the payer device  10 A may scan, detect, image or read the pay code and may extract the pay code data. At block  216 , the pay code data may be stored in the payer device  10 A. At block  218 , the pay code data (including the transaction ID) that is extracted may be used to query the pay code server  50  to retrieve transaction details (corresponding to (e.g., associated with) the transaction ID and/or other transaction data of the pay code) from the pay code server  50 . At block  220 , the transaction details may be supplied by the pay code server  50  to the payer device  10 A in response to a request (query) from the payer device  10 A. For example, the transaction ID or other transaction data extracted from the pay code by the payer device  10 A may be matched to information stored in the pay code server  50 . If a match results, the corresponding transaction details may be sent to the payer device  10 A. 
     At block  222 , the payer device  10 A may display or present the transaction details. At block  224 , the user (e.g., of the payer device) may enter or may select transaction custom options that may include transaction options such as quality, quantity, color, size and/or other product-specific or service-specific selections or options. The transaction custom options may also include shipping details such as shipping rates, shipping speed, and/or address information, among others. At block  226 , the payer device  10 A may send the preselected transaction custom options and/or the user-selected transaction custom options to the pay code server  50  that may verify the transaction custom options. 
     At block  228 , the pay code server  50  may forward the received transaction custom option or options to the merchant  40 , which may verify them and may calculate, for example, shipping fees and taxes, as appropriate. At the same time as the verification operation or by user option, the payer device  10 A, based on the information from a transaction skeleton may provide the payer  10  with the option to fill-in shipping information for physical goods, quality or option items such as sizes, colors and locations, as explained above. 
     At block  230 , the payer device  10 A can be used to select a funding card or a funding source. For example, if the payer  10  has more than one funding source (e.g., credit cards, debit cards, hybrid cards or other sources of funding such as utility accounts, revolving credit lines, home equity loans, or nearly any other form or source of funds that are available to the payer), the payer  10  can select one funding card or source to be used for a given transaction through the payer device  10 A. At block  232 , the funding details may be forwarded to the pay code server  50 . 
     In certain exemplary embodiments, the pay code server  50  may be dedicated to a particular funding source. In other exemplary embodiments, it will be apparent to one having ordinary skill in the relevant art that the pay code server may be integrated with other systems of the issuer  20  or acquirer  30  depending on the system implementation and may or may not include a dedicated pay code server  50 . 
     At block  232 , the pay code server  50  may identify funding details associated with funding the transaction, for example the issuer  20 , the acquirer  30  and/or the account balance associated with the funding card, among others. At block  234 , the identified funding details may be used to approve or disapprove the transaction and to notify the merchant  40  and the payer  10  via, for example, the payer device  10 A such that the merchant  40  can complete the associated order. At optional block  238 , the approval may be presented (e.g., displayed) on the payer device  10 A. 
     In certain exemplary embodiments, the completion of the order may include removing, by the merchant  40 , the product from inventory or scheduling, by the merchant  40 , the service based on a validation code from the pay code server  50 . 
     With respect to further details regarding the approval of the transaction and notification to the user  10  and/or the merchant  40 , attention is directed to  FIGS. 12, 13 and 14 . 
     Although the basic pay code transaction flow has been disclosed, it is contemplated that various modifications and specific implementations of transactions using pay codes may be possible.  FIGS. 3-5, 6A-6B, 7A-7C, 8A-8B, 9A-9B, 10, 11A-11B, and 22A-22B  disclose exemplary transaction flows using such pay codes. It should be noted that these are merely exemplary transactions to which the present disclosure is not limited. 
     Person-to-Person Pay Code Transactions 
       FIG. 3  is a flow diagram illustrating an exemplary person-to-person (P2P) pay code flow. 
     The P2P pay code flow may include (e.g., involve) first and second payee devices  10 A and  10 B. As an exemplary scenario, two people might desire to settle a debt. The first person or payee, who is owed the debt by the second person or payer, may open a pay code application on a smart phone  10 A and may enter the amount of debt (e.g., transaction details). This may be implemented as a transaction detail entry screen or “get paid” screen. The second person or payer also may open a pay code application on a second smart phone  10 B to a “pay” screen. The payee&#39;s smart phone  10 A may generate a screen with a pay code, for instance, a matrix barcode or QR code that may be readable by barcode scanners, mobile phones with a camera, or other smart phones, and may include transaction details. The payer may point the camera of the second smart phone  10 B at the screen (e.g., display) of the first smart phone  10 A and may image the displayed barcode. Once the displayed barcode is read, which may be almost instantaneous, the payer may choose which financial transaction card to pay with and may finalize the transaction. The payee may be alerted that the payment is complete via the pay code server  50 . 
     As illustrated in  FIG. 3 , the P2P pay code flow may be as follows. At block  302 , the payee device  10 B may enter transaction details and, at block  304 , may send the transaction details to the pay code server  50 . At block  306 , the transaction details may be received by the pay code server  50 . The pay code server  50  may create an electronic record of the transaction, and, at block  308 , may return pay code data (e.g., at least the transaction ID, as well as other optional information) to the payee device  10 B. At block  310 , the payee device  10 B may receive the pay code data and, at block  312 , may generate, and may display the pay code data and/or the pay code. At block  314 , the payer device  10 A can be used to scan the pay code to extract the pay code data. At block  316 , the pay code data may be stored. At block  318 , the pay code data may be used to retrieve transaction details from the pay code server  50 . 
     At block  320 , the transaction details may be provided by the pay code server  50  upon request (or in response to a request, e.g., a query) by the payer device  10 A. At block  322 , the payer device  10 A may display or present the transaction details and, at block  330 , may permit the payer an option to select or pick a funding card or funding source such that the payment details may be sent to the pay code server  50 . 
     At block  332 , the funding details may be generated by and may be stored in the pay code server  50 . At block  334 , based on the funding details, the pay code server  50  may approve or deny the transaction. At blocks  338  and  340 , the pay code server  50  may notify the payer via the payer device  10 A and the payee via the payee device  10 B of the results of the approval process. For example, the payee device  10 B may receive an approval display which indicates whether the transaction has been approved or denied and may optionally include transaction details and the payer device  10 A may also receive an approval display which indicates whether the transaction has been approved or denied and may also optionally include transaction details. 
     It is contemplated that the payee may receive an approval message such that some or all transaction details may not be shared with the payee. For example, the payer may pre-establish the transaction details to be provided to the payer to maintain security of the transaction details. That is, the transaction approval process does not require the use of the payee&#39;s systems for transaction approval that may improve security of the payer&#39;s transaction and personal information (e.g., credit account information, payee name, payee signature, etc). 
     Although the pay code server  50  is described as providing transaction approval, it is contemplated that the pay code server may be in communication with the transaction approver for such approvals. It is also contemplated that the pay code server may be a service provider for one or a plurality of issuers and may incorporate approval policies specific to each issuer for such transaction approvals. 
     E-Commerce Pay Code Transactions 
       FIG. 4  is a flow diagram illustrating an exemplary e-commerce pay code flow. As an example, a consumer may use a payer device  10 A (or other computing platform) to shop via the Internet (online) with a retailer that may be a pay code enabled merchant  40 . When checking out, the consumer may scan a convenient pay code (e.g., a barcode) that is generated on the screen of the payer device  10 A by the merchant using a pay code application. Further details of how the mobile device may effectively and indirectly take control of a web application session is described below under the subheading “Remote Control of Web Applications”. The e-commerce retailer can view that the transaction had been completed without requiring the potentially burdensome process of obtaining financial transaction card details. 
     Referring now to  FIG. 4 , in the exemplary e-commerce pay code flow, at block  402 , a user shopping at an e-commerce website  40 A, can build a checkout cart and may choose to check out using a pay code as a presented option on the e-commerce website  40 A. At block  404 , the e-commerce website  40 A may send transaction details to the pay code server  50 . At block  406 , the transaction details may be received and stored by the pay code server  50  and, at block  408 , they may be used to create an electronic record of the transaction. At block  410 , the pay code server  50  may return the pay code data (e.g., at least transaction ID and perhaps other optional data) to the e-commerce website  40 A. At block  412 , the received pay code data may be used to generate and to display the pay code and may be sent to the payer device  10 A. At block  414 , the payer device  10 A may scan the pay code and may extract the pay code data. At block  416 , the extracted pay code data may be stored and, at block  418 , may be used to retrieve transaction details from the pay code server  50 . 
     At block  420 , the transaction details may be retrieved by the pay code server  50  and returned (e.g., sent) to the payer device  10 A. At block  422 , the payer device  10 A may optionally display (e.g., present) the transaction details. Based on information in the transaction skeleton, the payer  10  may also reference from other electronic sources or data and may fill in manually or automatically the referenced data, such as shipping information for physical goods, or other transaction details to facilitate the transaction. At block  430 , the payer device  10 A may also be used by the consumer to select the funding card or the funding source and to send the payment details to the pay code server  50 . At block  432 , the received funding details may be used to approve or deny the transaction and the result of this approval process may be sent to the payer device  10 A, as well as to the merchant  40 A. At block  438 , the payer device  10 A may display the denial or the approval along with some optional transaction details. At block  442 , the merchant  40 A in the same timeframe (e.g., simultaneously) may complete the order, if approved, and, at block  440 , may display the approval or denial on the e-commerce website  40 A. 
     In certain exemplary embodiments, the approval may be displayed instantly (e.g., in real-time or near real-time) on the e-commerce website  40 A, and in the same window (or display) as the user was using for online shopping. 
     Quick Payment Pay Code Transactions 
       FIG. 5  is a flow diagram illustrating an exemplary quick payment pay code flow. 
     In accordance with an exemplary embodiment, in a full service restaurant a customer of the restaurant can eat his meal and then pay the bill or, in other more informal restaurants, the bill may be paid when the food is ordered or served. The server may display a receipt that may be printed on paper for review. Optionally, the bill may be displayed on a display device that may be coupled to or a part of a transaction terminal, a portable device and/or a payer device used for ordering food. The display device may be part of a food management system (e.g. order taking and billing system) which may be used to carry out the general business of the restaurant. Instead of carrying out the transaction using a conventional credit or debit card, which might involve waiting for the server to return with a payment slip or the like, the customer as the payer may use, for example, a smart phone to complete the transaction. 
     For example, the payer may scan a barcode associated with the transaction (for example, from the display or a printed bill), may add a tip for the waiter and may choose (e.g., select) via user selections a funding card, which is to be used. The payer may confirm the transaction, as well. The restaurant&#39;s food management system can check to confirm that the proper payment was made and clear the transaction. 
     Many restaurants are now using portable, wireless devices to take orders, which may simultaneously inform the kitchen staff of the order selected by the customer and may establish the transaction in the restaurant&#39;s food management computer system. In this implementation, the server could display the same electronic device when the screen shows the pay code. In this way, the customer can review the bill, can confirm the bill details and then can scan the pay code assuming there is no dispute. 
     It is contemplated that these types of electronic devices can be distributed to the customers (patrons). For instance, the patrons can review the menu, make their selections without necessarily involving the server, and once the meal has been provided, the patrons may make a payment for the meal using the pay code and, for example, the patron&#39;s smart phone (or wireless device), thus minimizing the impact of time and complexity of the payment process on the server. The patron may at the same time (e.g., simultaneously) build the electronic record of the transaction without substantial human intervention other than the patron&#39;s use of the smart phone or a wireless device. 
     Referring now to  FIG. 5 , at block  502 , a customer may eat at a restaurant and may request to checkout. At block  504 , the restaurant point of sale system (POS)  40 B may send transaction details to the pay code server  50 . At block  506 , the transaction details may be received and stored by the pay code server  50  and, at block  508 , the transaction details may be used to create an electronic record of the transaction. At block  510 , the pay code server  50  may return (e.g., send) the pay code data (e.g., at least transaction ID and perhaps other optional data) to the POS  40 B. At block  512 A, the received pay code data may be used to generate and to display and/or print the pay code. The pay code may be scanned by the payer device  10 A or may be electronically sent (e.g., communicated) to the payer device  10 A. At block  514 , the payer device  10 A may scan the pay code and may extract the pay code data. At block  516 , the extracted pay code data may then be stored and, at block  518 , may be used to retrieve transaction details from the pay code server  50 . 
     At block  520 , the transaction details may be retrieved by the pay code server  50  and returned (e.g., sent) to the payer device  10 A. At block  522 , the payer device  10 A may optionally display (e.g., present) the transaction details. Based on information in the transaction skeleton, the payer  10  may also reference from other electronic sources data and may fill in manually or automatically the referenced data (such as the amount of the tip for the waiter) to facilitate the completion of the transaction. At block  524 , the payer device  10 A can also be used by the customer to select a funding card and may send the payment details to the pay code server  50 . At block  532 , the received funding details may be used to approve or deny the transaction, at block  534 , and the result of the approval process may be sent to the payer device  10 A and/or the POS  40 B. At block  538 , the payer device  10 A may display the approval along with some optional transaction details. At block  542 , the POS  40 B may simultaneously complete the order and may update its records. 
     Open Tab Pay Code Transactions 
       FIGS. 6A and 6B  are a flow diagram illustrating an exemplary open tab pay code flow. 
     As shown in  FIGS. 6A and 6B , at block  602 , a bartender or other service provider may choose to open a new tab (or transaction) for a customer at an establishment (e.g., a bar, a gaming establishment, hotel, etc.). At block  604 , a point-of-sale system (POS)  40 A of the establishment may send an open transaction request to the pay code server  50 . 
     At block  606 , the pay code server  50  may receive the transaction request and, at block  608 , may create and store an electronic record of the transaction. At block  610 , the pay code server  50  may return the pay code data to the POS  40 A. At block  612 B, the pay code data (e.g., a bar code, such as a QR code) may be used by the printing of an open tab receipt with the pay code data printed thereon. At block  614 , the patron  10  of the establishment (e.g., bar) may use the payer device  10 A to scan the pay code printed on the open receipt to extract the pay code data. At block  616 , the pay code data may be stored on the payer device  10 A. 
     At block  618 , the patron  10  of the establishment may select a funding source using the payer device  10 A. At block  632 , the pay code server  50  may receive the funding details and, at block  644 , the pay code server may approve (e.g., pre-approve) the electronic transaction and may notify the patron  10 , the merchant  40 , and/or the POS  40 A. At block  638 , the payer device  10 A may display the approval (or denial). Substantially at the same time as the display of the approval, at block  646 , the POS  40 A may initiate tracking of the bill (tab). At block  648 , the POS  40 A can send a request to close a tab, and send the updated details to the pay code server  50 . At block  650 , the transaction details may be updated in the pay code server  50  and may, based on a request from the payer device  10 A, send the updated transaction details to the payer device  10 A. 
     At block  652 , the patron  10  or user using the payer device  10 A may receive and update the transaction details locally, which may involve rescanning of the printed pay code from the receipt or transmission of the transaction details to the payer device  10 A. The update may be implemented through user input via interface keys on the payer device  10 A. For example, the update may be initiated by pressing a button requesting the update or otherwise inputting such a request. At block  654 , the user of the payer device  10 A can approve the transaction amount. The pay code server  50  may approve or disapprove the transaction in accordance with exemplary operations shown in  FIGS. 12-14 , for instance. The pay code server  50  may notify the patron  10  and/or the merchant POS  40 A of the approval or disapproval action. At block  656 , the merchant POS  40 A can complete the order and may close out the bill or tab. At block  638 , the payer device  10 A can present, display or show the approval to let the patron  10  know (confirm) that the bill has been paid and that the patron  10  may now be free to leave. 
     Multiple Payer Pay Code Transactions 
       FIGS. 7A, 7B, and 7C  are a flow diagram illustrating an exemplary multiple payer pay code flow. 
     Referring now to  FIGS. 7A, 7B and 7C , an exemplary sequence may include (involve) the merchant  40 , the pay code server  50  and the payer devices  10 A and  10 B. At block  702 , the merchant  40  can build basic transaction details and, at block  704 , the merchant  40  can send those transaction details to the pay code server  50 . At block  706 , the transaction details may be stored at the pay code server  50 . At block  708 , the transaction details at the pay codes server  50  may be used to create an electronic record of the transaction and the pay code server  50  may return the pay code data (e.g., transaction ID, etc.) to the merchant  40 . At block  710 , the pay code data may be stored at the merchant  40  and, at block  712 , the pay code data may be used to generate and to display the pay code (e.g., bar code). 
     At block  714 , a first payer device  10 A may scan one or more pay codes and may extract the pay code data, which may be stored in the first payer device  10 A, at block  716 . At block  718 , the pay code data may be used to retrieve details from the pay code server  50 , which may be stored, at block  720 , in the pay code server  50 , as transaction details. At block  722 , the first payer device  10 A may generate a display of the transaction detail. At block  730 , the first payer device  10 A may provide the user with the option to select the funding card or the funding source and may send the payment details to the pay code server  50 . At block  732 , the funding details may be generated and at block  734 , they may be used in an approval process to approve or deny the corresponding transaction. The user of the first payer device  10 A may be notified accordingly. At block  738 , the first payer device  10 A, having received the result of the approved process, may display the approval result. 
     At block  758 , the second payer device  10 B may scan the pay code and may extract the pay code data and, at block  760 , the pay code data may be stored in the second payer device  10 B. At block  762 , the pay code data may be used to retrieve transaction details and a current balance from the pay code server  50 . At block  764 , the transaction details may be sent to and stored in a database at the pay code server  50 . At block  766 , the second payer device  10 B may display the received transaction details and, optionally, may permit the user  10  to select the funding card or the funding source. At block  730 , the second payer device  10 B also may send the payment details to the pay code server  50  and, at block  732 , the funding details may be stored in the pay code server  50 . At block  739 , the pay code server  50  may approve or deny the transaction and may notify the user of the second payer device  10 B and the merchant  40  of the approval result. At block  738 , the approval or denial may be displayed to the user through the second payer device  10 B. At block  736 , at or about the same time as the display to the user of the second payer device  10 B, the merchant  40  may complete the order. 
     As is understood from the multiple payer process, the first and second users can “split the tab” by having one user paying for a part of the transaction from its funding source and the second user then paying for the balance of the transaction on the second user&#39;s funding source. This may be advantageous for splitting tabs or any other circumstance where more than one person is motivated to pay part of a total bill. 
     Although two payers  10  are disclosed, it is contemplated that any number of payers may split the total bill (e.g., tab). 
     Poster-Based Pay Code Transactions 
       FIGS. 8A and 8B  are a flow diagram illustrating an exemplary poster-based pay code flow. 
     As shown in  FIGS. 8A and 8B , at block  802 , a poster creator  40 C can send a request for a new transaction skeleton from the pay code server  50 . At block  870 , the pay code server  50  may create a new transaction skeleton (e.g., pricing and/or description, among others). At block  872 , the pay code server  50  may create an electronic record of the transaction, may return the pay code data (transaction ID, etc.) to the poster creator  40 C, and may create and display the pay code data. At block  874 , the pay code data may be visually shown, or transmitted to the poster creator  40 C, which may create a poster with the pay code (e.g., bar code) visible to the user. 
     In this exemplary scenario, rather than the pay code representing a unique transaction, it may encode a transaction skeleton or may identify a transaction skeleton stored in the pay code server  50 . The merchant  40  may convey through the poster details of the transaction what the merchant  40  desires included in the transaction should a customer  10  choose to buy the good or service being advertised. It is contemplated that the poster creator  40  may be a merchant who prints posters or directs a commercial printer to print the posters on the merchant&#39;s behalf. It is also contemplated that a near field communication chip may operate simultaneously with the pay code, to convey additional data to the customer  10  if payer device  10 A includes a near field communication chip. 
     At block  814 , the payer device  10 A may scan the skeleton pay code and may extract the pay code data and, at block  816 , the pay code data may be stored. At block  818 , the pay code data may be used to retrieve transaction details from the pay code server  50 . At block  820 , the transaction details may be stored in a database of the pay code server  50 , but can also be encoded in the pay code, or in a near field communication device. At block  822 , the payer device  10 A may display the transaction details and, at block  824 , the user  10  may enter and/or may select custom transaction options (e.g., quality, color, size, etc.) and shipping details, for instance. At block  826 , the pay code server  50  may receive from the payer device  10 A the custom transaction options and may also verify the custom transaction options. At block  828 , the poster creator  40 C may receive from the pay code server  50  the custom transaction options, may verify the custom transaction options, and may calculate costs for shipping and taxes, as required. 
     At block  830 , the user  10  can select the funding card or funding source and can send payment details to the pay code server  50  and, at block  832 , the funding details may be stored in the pay code server  50 . At block  839 , the system may generate a unique transaction ID that may tie the purchase to a specific user. Up to that point, there is no requirement to generate a transaction ID because there is no confirmed intent to buy the good or service. The transaction skeleton may be uniquely identified in the system. As such, the transaction skeleton is not a unique transaction yet, but rather the unique item, cart or container having particular details to copy into a new transaction at the payer&#39;s request. The pay code server  50  may also approve or deny the transaction in accordance with, for instance, the process flows of  FIGS. 12-14 . At block  838 , the payer device  10 A can display the result of the approval process and, at block  836 , if approved; the poster creator  40 C can complete the order. 
     Although the pay code skeleton is disclosed for use with posters, it is contemplated that pay code skeletons may be used with any printed advertisement of a good or a service to for example, identify the model or general service being offered and the details thereof prior to a completed transaction. In one exemplary embodiment, the pay code skeleton may be used with an advertisement on a website. 
     In certain exemplary embodiments, the pay code skeleton may be used to identify a product or service for sale and may enable, for example, the review of detailed offers (advertisements) at: (1) the payer device; (2) an electronic display in visual range of the payer device; and/or (3) an acoustic device in acoustic range of the payer device. In one embodiment, it may be used in conjunction with an acoustic stimuli-based distribution, as described below. The payer device may also direct the presentation of the detailed offer (video or acoustic) to the various devices based on location information from a global positioning system (GPS) or by using device-to-device wireless communications. 
     Television-Based Pay Code Transactions 
       FIGS. 9A and 9B  are a flow diagram illustrating an exemplary television-based pay code flow. 
     As shown in  FIGS. 9A and 9B , at block  902 , a shopping channel and/or an infomercial/advertisement provider  40 D can request a new transaction skeleton. At block  970 , the pay code server  50  may create a transaction skeleton (including, for example, pricing, description, etc.). At block  972 , the pay code server  50  may create an electronic record of the transaction and may return the pay code data (such as the transaction ID and/or other transaction details, among others) and, at block  912 , may generate and may display the pay code data and/or may transmit it to the shopping channel, infomercial or advertisement provider  40 D. 
     At block  974 , the shopping channel or infomercial/advertisement provider  40 D may display the pay code (e.g., bar code) with a video overlay so that the pay code may be displayed by the payer device  10 A. In one embodiment, the pay code may be encoded as event data in a video (e.g., in a vertical blanking interval) as described below. At block  914 , the payer device  10 A may scan the pay code and may extract the pay code data and, at block  916 , the pay code data may be stored in the payer device  10 A. In one embodiment, the pay code data may be extracted through voice or human based gesture actions, as described below. At block  918 , the payer device  10 A may be used to retrieve transaction details from the pay code server  50 . The transaction details may be previously stored in a database at the pay code server  50 , at block  920 . At block  922 , the payer device  10 A can display the received transaction details and, at block  924 , the payer device  10 A can permit the user to enter or select transaction custom options (such as quality, color, size, shipping details, etc.). 
     At block  926 , the pay code server  50  may verify transaction custom options. At block  928 , the shopping channel/infomercial or advertisement provider  40 D may also verify the transaction custom options and may calculate shipping and taxes, as appropriate (or required). At block  930 , the user  10  of the payer device  10 A may pick (e.g., select) a funding card or funding source and may send the details to the pay code server. At block  932 , the funding details may be stored and, at block  939 , the funding details may be used to generate a new transaction ID and/or approve or deny the transaction. At block  936 , the shopping channel or infomercial/advertisement provider  40 D can, if approved, complete the order and, at block  938 , the result of the approval process (e.g., approval or disapproval of the transaction) may be displayed on the payer device  10 A. 
     Although the pay codes are disclosed as being displayed in a video overlay, it is contemplated that any technique enabling the presentation or transfer of an image of the pay code from a video signal to a payee device may be used. For example, a set-top box may enable the transfer of image data (e.g., the pay code skeleton) inserted into a blanking interval of the video signal to the payer device via wired or wireless communications for display on the payer device. In one exemplary embodiment, the transfer of the pay code skeleton to the payer device is triggered by human voice or gesture based commands, which may be read, for example, by a human interaction device. 
     Multiple Recipient Pay Code Transactions 
       FIG. 10  is a flow diagram illustrating an exemplary multiple recipient or payee pay code flow. 
     As shown in  FIG. 10 , first and second users of a service can be recipients  60 A and  60 B. For instance, at block  1002 , the first recipient  60 B may request a new multi-recipient transaction from the pay code server  50 . At block  1078 , the pay code server  50  may create an electronic record of the transaction and may assign a transaction ID. At block  1080 , the first recipient  60 B can add transaction details, such as an amount, a line item, etc. At block  1020 , the transaction details may be received from the pay code server  50  and may be stored in a database associated with the pay code server  50 . Additionally, at block  1082 , the second recipient  60 A can add transaction details for herself, such as an amount, a line item, etc. At block  1012 , the pay code server  50  may generate and may display the pay code. 
     At block  1014 , the payer device  10 A can scan the pay code and may extract pay code data. At block  1016 , the pay code data can be stored. At block  1018 , the payer device  10 A may retrieve transaction details from the pay code server  50 . At block  1022 , the payer device  10 A may display (e.g., present) the transaction details. At block  1030 , the payer device  10 A may offer the ability to pick (e.g., select) the funding card or source and may send the payment details to the pay code server  50 . At block  1032 , the funding details may be used to approve or deny the transaction in the manner shown in  FIGS. 12-14 . At block  1034 , the pay code server  50  may notify both the user  10  and the recipients of the result of the approval process. At block  1038 , the result of the approval process (approval or denial) may be displayed or presented by the payer device  10 A and the first recipient  60 B such that, at block  1036 , if approved, the first recipient  60 B can complete the order. In some embodiments, the result may also be displayed or presented to the second recipient  60 A such that, if approved, the second recipient  60 A can complete the order. 
     Three examples of this form of transaction may include: 
     A user may shop on an e-Commerce site such as etsy.com where multiple merchants post their goods (e.g., wares). The user may build a cart of items that the server may keep track of for the individual merchants that require payment. The user may be presented with a single transaction confirmation screen and may be notified that the transaction may appear as several charges on their bill. The pay code server  50  may notify each merchant of the purchase and may initiate the multiple transactions (individual purchases) on the user&#39;s behalf. 
     In a physical mall setting, a shopper may not want to carry around bags and boxes of purchases. Rather, the shopper may initiate an electronic cart and may walk around the mall or series of stores. In this exemplary scenario, the shopper may build the electronic cart by collecting pay code skeletons from goods and/or service offerings and may complete the transaction at their leisure with shipping instructions (such as shipping location) for the goods or services, for example. 
     Real-estate, automobile purchases, and other relatively complex transactions that involve multiple players are another type of multi-recipient transaction, e.g., a transaction in which a payer may confirm payments to several payees (e.g., title companies, closing agents, insurance agents, government authorities, former owners, etc.) 
     Retailer Pay Code Transactions 
       FIGS. 11A and 11B  are a flow diagram illustrating an exemplary retailer pay code flow. 
     Referring to  FIGS. 11A and 11B , a retail store may have a display  40 D, for example, viewable by customers (e.g., in a window or in the retail store). At block  1102 , the retail store may request a new transaction skeleton of the pay code server  50 . At block  1170 , the pay code server  50  may create a new transaction skeleton and at block  1172 , the pay code server  50  may create an electronic record of the transaction. The pay code server  50  may also return the pay code data (e.g., the transaction ID, etc.) and at block  1112 , may optionally generate and display the pay code (e.g., bar code). At block  1074 , the retail store  40 D may print or may generate and print the pay code on a retail display (e.g., an item pricing display, an in-store marketing display or any other display for displaying product or service information). 
     At block  1114 , the payer device  10 A can scan the pay code and may extract the pay code data. At block  1116 , the pay code data may be stored and used, at block  1118 , to retrieve transaction details from the pay code server  50 . At block  1120 , the transaction details may be stored in the pay code server  50  and may be returned to the payer device  10 A such that, at block  1122 , the transaction details may be displayed on (e.g., presented by) the payer device  10 A. At block  1124 , the payer  10  may enter and/or select transaction custom options (e.g., the quality, color, size, shipping details, etc.). At block  1126 , the transaction custom options may be verified in the pay code server  50  and, at block  1128 , the transaction custom options may be verified in the retail store. The retail store may also calculate shipping and taxes, if appropriate. 
     At block  1130 , the payer device  10 A may permit the user to select or pick a funding card or source and can send the payment details (or funding details) to the pay code server  50 . At block  1132 , the funding details may be used to generate a new transaction ID and, at block  1134 , may carry out the approval process for the transaction. At block  1136 , the information may be conveyed to the retail store or store display  40 D, which, if approved, may complete the order. At block  1138 , the user  10  via the payer device  10 A, may display the result of the approval process. 
     Delayed Payment Pay Code Transactions 
       FIGS. 22A and 22B  are a flow diagram illustrating an exemplary delayed payment pay code flow. 
     Referring now to  FIGS. 22A and 22B , an exemplary sequence may include (involve) the merchant  40 , the pay code server  50  and the payer device  10 A. At block  2302 , the merchant  40  can build basic transaction details and, at block  2304 , the merchant  40  can send the transaction details to the pay code server  50 . At block  2306 , the transaction details may be stored at the pay code server  50 . At block  2308 , the transaction details at the pay codes server  50  may be used to create an electronic record of the transaction and the pay code server  50  may return the pay code data (e.g., transaction ID, etc.) to the merchant  40 . In an exemplary embodiment, the pay code data may include basic transaction data (e.g., product information, purchase price, etc.) In another exemplary embodiment, information for a transaction ID can be stored (e.g., on the device, such as in an application database, or in a chip accessed using near field communication). At block  2310 , the pay code data may be stored at the merchant  40  and, at block  2312 , the pay code data may be used to generate and to display the pay code (e.g., bar code). 
     At block  2314 , the payer device  10 A may scan one or more pay codes and may extract the pay code data, which may be stored at block  2316 . At block  2318 , the payer device  10 A may generate a display of the pay code data, including any included basic transaction data. At block  2320 , the payer device  10 A connects to a network (e.g., a mobile network), and thereby retrieves additional details from the pay code server  50 , at block  2322 , which may be stored, at block  2324 , in the pay code server  50 , as additional transaction details. At block  2326 , the payer device  10 A may generate a display of the additional transaction details. At block  2328 , the payer device  10 A may provide the user with the option to select the funding card or the funding source and may send the payment details to the pay code server  50 . At block  2330 , the funding details may be generated and at block  2332 , they may be used in an approval process to approve or deny the corresponding transaction. The user  10  and merchant  40  may be notified accordingly. At block  2334 , the merchant  40 , having received the result of the approved process, may display the approval result, which may also be displayed to the user  10 , at block  2336 . 
     As is understood from the delayed payment process, a payer who views an advertisement or otherwise wishes to make a purchase for a product when lacking a network connection, can initiate a transaction by reading (e.g., scanning) a pay code and then proceeding with the transaction after a network connection has been established. 
     A user may view a poster advertising tickets for a concert event in an underground transit system. The user can scan a pay code on the poster using the payment application on their mobile device without network connectivity. The user can see information about the concert on their mobile device that was encoded in the pay code via optical, aurial or in a nearby near field communication (NFC) chip as described elsewhere. As the user establishes connectivity to their mobile network, the tickets become available to purchase on the mobile device display, or can be referenced from the user&#39;s activity history. The product information is updated from the pay code server so that the latest information, pricing, availability, etc., is presented to the user before payment is confirmed. 
     For example, a driver may be at a remote gas station and scan a pay code at the gas pump to initiate payment for gas. The driver can enter an amount to pay as displayed on the pump, and the payment application on their mobile device can schedule to make the payment when network connectivity is re-established. The merchant gas station can capture time and other details (e.g., license plate) that can be submitted to the pay codes server when network connectivity is re-established, in order to reconcile the payment. When the driver enters an area and establishes connectivity to their mobile network, the scheduled payment is processed and the driver is notified. 
     As another example, a consumer is flying in an airplane from one destination to another may be prohibited from connecting to a mobile network. The consumer may browse a product catalog available on the airplane that advertises goods or services, and, using the payment application on their mobile device, scan pay codes for any of the goods or services that the consumer wishes to purchase. When the consumer&#39;s airplane lands and network connectivity is established with the mobile device, product information for each of the scanned goods or services can be presented to the consumer, who may then confirm transaction details and payment, or an option offered for this done automatically by the mobile device. 
     Payment Processing 
       FIG. 12  is a flow diagram illustrating an exemplary payment processing flow diagram for larger merchants.  FIG. 13  is a flow diagram illustrating an exemplary payment processing flow diagram for smaller merchants or for on-behalf processing.  FIG. 14  is a block diagram illustrating an exemplary computer architecture and exemplary data in accordance with various embodiments for remote control of website content by a user device using machine-readable pay codes. 
     Referring to  FIGS. 12-14 , exemplary payment processes will be explained with reference to payer device  10 A, the pay code server  50  and the merchant or merchant POS  40  with the optional inclusion of a gateway or acquirer  30 . These details, which are shown in  FIGS. 12 and 13 , correspond to the approval transaction process flow, for example, of the basic pay code flow of  FIGS. 2A and 2B , at block  234 . 
     Large Payment Processing 
     As shown in  FIG. 12 , at block  1280 , the funding details and the transaction details may be presented in an electronic communication, as a payment ready for processing by the pay code server  50 . At block  1282 , the pay code server may extract the funding details from the electronic communication. At block  1284 , the funding data may be routed to the merchant  40  for processing. At block  1286 A, the merchant  40  may process the transaction through the normal gateway/acquirer  30  that may be external or internal to the merchant  40 . At block  1288 A, the approval or denial details may be generated and may be sent back (returned) to the pay code server  50  and may be sent within the merchant  40  to complete the order, if approved, as shown in  FIGS. 2A and 2B , at block  236  and to display the approval or denial on the payer device  10 A ( FIGS. 2A and 2B , at block  238 ). At block  1290 , the pay code server  50  may receive a process approval indication or denial indication, and may continue the pay code flow (e.g., allowing the merchant  40  to complete the order, if approved, and to display the approval/denial, as shown in  FIGS. 2A and 2B ). 
     Small Merchant or “On Behalf” Payment Processing 
       FIG. 13  shows a variation of a process flow of  FIG. 12  and this process flow may be more suitable for the current method of payment processing for small merchants or “on behalf” processing (as conventionally referred to in the art). The modifications that occur to the legacy of payment processing may include, at block  1380 , that the pay code server  50  may receive payment transaction data ready for processing, at block  1382 , the funding details may be extracted and, at block  1384 , the pay code server  50  may place an authorization request using the merchant&#39;s credentials. 
     In certain exemplary embodiments, the merchants may issue credentials (e.g. username and/or password) with which they authenticate with their gateway or acquirer  30 . The pay code server  50  may support the credentials as appropriate. At block  1386 B, the gateway or acquirer  30  may process the transaction and, at block  1388 B, the gateway or acquirer  30  may generate the approval/denial details. At block  1390 , the pay code server  50  may receive and process approval/denial indication and, at block  1394 , may route the approval details to the merchant  40 . At block  1396 , the merchant  40  may receive the approval/denial details and, at block  1392 , the pay code server  50  may continue on with the pay code flow as indicated, for example in  FIGS. 2A and 2B  at block  234 , for sending information to allow the merchant  40  to complete, if approved, the order in  FIGS. 2A and 2B  at block  236 . At block  1380 , the approval/denial result at block  238 , if appropriate may be displayed. 
     Remote Control of Web Applications 
     As explained above with respect to the on-line payment scenario of the e-commerce pay code transactions shown in  FIG. 4 , the mobile device effectively and indirectly may take control of a web application session that may or may not be linked to the transaction. For example, a user may go to a website through a URL (e.g., remotecontrolme.com) via a PC, Mac, TV or a screen from a store window, for instance. The website (e.g., remotecontrolme.com) may present a unique pay code. The unique pay code does not have to be part of any payment or purchase process, and hence, for this section, the pay code is described as a unique code, and the payer device is described as a user device, but otherwise they may be the same. An app (e.g., application software) on the user device  10 A (e.g., remotecontrolme app) may scan or may read the unique code effectively allowing the user device  10 A to setup an alternate session to control navigation and features run on the PC, TV and/or screen from the store window to control its content. As one example, the content on the PC, TV, or screen from the store window may not be controlled through the user interface of these devices, but rather through the remote actions of a user device  10 A via the remotecontrolme app. In essence, a user device  10 A can act as a wireless mouse controlling a display belonging to a merchant, or advertiser or another, in shop windows, or electronic billboards, etc. This may be particularly advantageous in areas where the audience/users are “captive” such as public transportation, planes, taxis, waiting rooms, etc. 
     The method of indirect control of a website from the website provider&#39;s perspective may involve displaying a unique machine-readable code unique to a specific display device displaying contents from the website through a server. The unique machine-readable code may be readable by a user (e.g., communication) device  10 A. The user device  10 A may be able to communicate with the server through a communication path (e.g., over WiFi or a mobile telephone network connected to the server, with or without intermediary communication paths such as the Internet). The communication may not involve (e.g., may be exclusive of) an input device associated with the display. 
     For example, the server may receive commands to control content displayed from the user device. The process may include a unique code server, or the unique codes may be provided by the same server as the website server. The commands may include the identity of the display device via the displayed unique machine-readable code read by the user device  10 A or via direct wireless communications with the display device. The website server may change the content displayed on the display device based on the unique machine-readable code. By creating a website that can generate a unique session identity code similar to a pay code, the server that provides the website may poll the unique code server  50  (or a different server) for instructions from the user device  10 A. The unique code app may scan the unique code and may provide payment information, but this mechanism is not limited to financial transactions. The merchant server that may be polling can recognize a payment has been fulfilled and can present receipt-type data. 
     Although the remote control of a website by a user device is described with reference to financial transactions, it is not limited to financial transactions and it is contemplated that many other types of transactions are possible. For example, by displaying a unique code on the website that is readable by a code-enabled device, rather than the conventional user interfaces such as keyboards or mice and/or touch screens associated with the display that displays the unique code, the user device  10 A can effectively take over control of the website or monitor through the internet such that the website may send display signals to the PC, TV or screen in a store window via the remote control of the user device. 
     This process has many applications far beyond financial transactions. For instance, specific product information (including advertisements) can be generated at the direction of the user device  10 A. Of course, the information is not limited to products but any content that is appropriate under the circumstances can be remotely controlled via unique codes scanned by the user device  10 A. Alternatively or additionally, additional security features can be established through the remote control of the website via this arrangement involving the user device  10 A reading the unique code displayed on the merchant display device. For example, product or service offering (e.g., information) may be displayed without the user providing information directly to the store. 
     Referring to  FIG. 14 , a display  1510 , which may be a screen in a merchant&#39;s shop, a television in a consumer&#39;s home, a PC and/or nearly any other type of display device, may display a unique code  1512 . The unique code  1512  may be generated through conventional interactions with a display device (e.g., the keyboard and mouse of a PC) or by generation of a unique code depending on the content displayed on the display device, which might change over time. The consumer&#39;s device  1520  which might be a smart phone, camera-enabled telephone or nearly any other device capable of wireless communications, and may be enabled to read the unique code  1512  (e.g., optically or through any other means for which the consumer device  1520  may be capable of reading the unique code  1512 ). The consumer device  1520  may transmit the unique code information that has been read through a network  1540 . 
     The network  1540  may be broadly understood to include one or more wireless links but is not limited thereto. For instance, the network  1540  may include a cellular network or a wireless link such as via Wi-Fi or Bluetooth® that might be a dedicated network or connected to the internet, for instance. The network  1540  may be conventional. The wireless network may communicate with the third party server  1530  that may be attached to a database  1530 A in any conventional manner. The third party server  1530  may be a merchant server that provides either the website content, the screen in the store or the content displayed on a TV. The TV may be a cable-based TV, a fiber optic-based TV or a satellite-based television, for instance. The display content may be a shopping network or nearly any other mechanism for advertising including product placement within television shows or movies. 
     Once the user device  1520  has read the unique code  1512  and transmitted it through the network (e.g., wireless network)  1540  to the server  1530 , the user device  1520  can then be used to control the content of the display  1510 . For instance, the user device  1520  may be used as a mouse to scroll around the display. The user device  1520  may also be used as an air mouse, where movement of the actual user device  1520  results in relative movement of a mouse in the display  1510 , e.g., through included accelerometers, gyroscopes, etc. The user device  1520  may also be used as an input device such as a keyboard as long as the display  1510  can be uniquely identified. For instance, the user device  1520  may send out command signals through the network  1540  to the server  1530  that may in turn change the content of the display  1510  on the user&#39;s PC via the internet, or the display on a cable TV through the cable TV&#39;s service provider or to the display in a shop window which may be through a closed network or through the internet or any other communication mechanism. That is, the user device  1520  can control a display  1510  via a server or other network mechanism  1530  that otherwise is unassociated and unlinked through a communication protocol identified and established using the unique code  1512 . 
     In this system, the unique code may identify a particular transaction on a webpage or website display by a first party. The user device  1520  of a second party equipped with a reader capable of reading the unique code may communicate data taken from the unique code and may convey it back to the first party together with additional information identifying the transaction and, optionally, other information about the second party (e.g., identity, time, location, account information, communication protocols, security measures, etc.). The user device  1520  can also be used by the second party to control the contents of the display provided by the first user. 
     As an example, a consumer (the second party) could be viewing a display screen in a shop window of a store of a merchant (the first party). When the consumer views something she likes, she may scan a pay code (e.g., a QR code) displayed with the product information from the consumer&#39;s smart phone. The smart phone can be programmed to provide menu options and may have an input key board such that the consumer can select additional information about the product, such as price and product details. This information may be conveyed through a mobile network to the store&#39;s servers, which then, having information from the QR code, can identify the particular screen in the shop window, and may send the requested information for display. The user can also use the smart phone to securely purchase the item, complete with the user&#39;s selection of a funding source and shipping details. In this way, the user does not have to interact with the input devices in the store. For example, such purchase may occur from a store display inside the store while the user  10  is outside the store. 
     This may be helpful when online shopping using someone else&#39;s computer, such as in a coffee shop, where access to the computer may not be limited to a particular person, and the auto-fill of information is not present or represents a security risk. The use of the user&#39;s smart phone bypasses this risk while still providing the convenience of having all the information the user might want or need to provide. The transaction also may minimize input by the user and may enable secure one-click shopping using a strange computer through this process. 
     Graphical User Interface for Pay Codes 
       FIGS. 15A-15C  illustrate a graphical user interface (GUI) including a pay code used in a checkout operation for purchasing a consumer good using a payer device  10 A. 
       FIGS. 16A-16F  illustrate a graphical user interface (GUI) of the payer device  10 A used for the purchase in  FIGS. 15A-15C . 
     Referring to  FIGS. 15A-15C and 16A-16F , after a product (e.g., a consumer good or service) is selected for purchase, the GUI of a computer display  1640  may display a first web page  1630  that may include first and second selectors  1610  and  1620 . The first selector  1610  may enable payment via a first mode using conventional checkout methods including payment by a credit card, a debt card, PayPal, etc. The second selector  1620  may enable payment using a pay code and a communication device (e.g., the payer device  10 A). The web page  1630  may include the first selector  1610 , the second selector  1620 , a price indicator  1625 , a currency type indicator  1635  and/or product details  1645 . For example, responsive to selection of the second selector  1620 , a second web page  1670  may be display presenting a pay code  1650  for purchase of the product. 
     After the purchase of the product is completed, a third web page  1680  may be displayed on the computer display  1640 . The third web page may include a confirmation of the purchase including transaction details such as (1) the product details  1685  (e.g., a product description, the product cost, the currency type associated with the transaction, etc.); (2) the card details  1686  (e.g., a credit card account, the expiration date associated with the card, security number, etc.) and/or (3) shipping details  1687  (the shipping address, any special handling details, etc.). 
     The user  10  may use the payer device  10 A with a pay code mobile application (mobile app) loaded or some other purchasing application. The payer device  10 A may include a GUI display and an imaging device, such as a camera. The mobile app may provide in the GUI display first through fourth selectable display windows  1710 ,  1720 ,  1730  and  1740 . The first selectable display window  1710  may enable scanning of the pay code  1650  directly from the second web page  1670  or via a printout of the second web page  1670 . The second selectable display window  1720  may enable the user  10  to position or reposition the payer device  10 A (e.g., imaging device) to properly set the pay code  1650  in the image for proper scanning. The third selectable display window  1730  may enable viewing of the product details. The fourth selectable display window  1740  may enable confirmation of transaction details and/or confirmation of payment approval. 
     The first selectable display window may include a pay icon  1712 , a receive icon  1714 , and a cart icon  1716 . The selection of the pay icon  1712  may enable viewing of the fourth selectable display window  1740 . The selection of the receive icon  1714  may enable scanning of the pay code  1650 . The selection of the cart icon  1716  may enable viewing of the third selectable display window  1730  showing product details of items in the cart (e.g., based on the pay code  1650  of products or services that have been scanned). The second selectable window  1720  may include a cancel icon  1722  enabling the cancelation of the scanning process and/or a scanning icon (not shown) that may enable scanning of the pay code  1650  or rescanning of the pay code  1650 , when the pay code image is outside of the view finder  1725 . 
     Responsive to imaging of the pay code  1650 , the second selectable display window  1720  may be displayed that enables the user  10  to position or reposition the payer device  10 A (e.g., imaging device) to properly set the pay code  1650  in the image for proper scanning. 
     The third selectable display window  1730  (or details screen) on the payer device  10 A may enable the user  10  to view the product details  1732 , may provide a user input area  1734  for a user to enter the quantity of the product to be purchased. In some embodiments, the quantity may default to one. After the user  10  inputs the quantity, the user  10  may choose to buy the product by selecting a “Buy Now” icon or via other selection means. 
     Responsive to selection of the “Buy Now” button, a fourth selectable display  1740  (or the confirmation screen) of the GUI may be displayed, which may provide (e.g., present): (1) a portion of the transaction details in a order summary area  1742 ; (2) a second portion of the transaction details in a details area  1746 ; (3) one or more payment options available to purchase the product in a payment option area  1744 ; and/or (4) one or more possible shipping locations options in the payment option area  1744 . The payment and shipping options may be preset by the user  10  prior to purchase of the product or may be established or overwritten for completion of the purchase of the product using the payment option area  1744 . In one exemplary embodiment, the user  10  has selected to ship the product to his home address and to use his MasterCard® account to pay for the purchase of the product. Responsive to selection of the payment by the user  10  via the “Pay Now” icon  1748 , the payment may be made via the payer device  10 A and pay code server  50  and confirmation of the payment may appear on the payer device  10 A as one or more overlays  1750  on the fourth selectable display window  1740 . 
     In some exemplary embodiments, it is contemplated that the pay code may alternatively be transferred via wireless communication such a WiFi or Bluetooth. In some exemplary embodiments, discounts may be available if goods or services are purchased using pay codes, or goods and services may be offered exclusively to customers using pay codes. 
     Although operation of the payer device GUI is described using a pay code scanned from a web page, it is contemplated that the pay code may be provided for scanning from any number of different mechanisms. For example, pay codes may be placed on advertisements, product containers, invoices, bills, movie or entertainment posters, etc. It is further contemplated that the payer device GUI may work with any pay code as long as it identifies the transaction details (e.g., the transaction skeleton and/or transaction ID). In some exemplary embodiments, the GPS or WiFi location services offered by smart phones and the like can be used, as well as additional information about the user, e.g., when ordering a taxi or other delivery type service to the current location of the user, through another party&#39;s web site, for instance. 
     As described herein, for example, the systems described above may be embodied in software (e.g., a plug-in or standalone software), in a machine (e.g., a computer system, a microprocessor-based appliance, etc.) that includes software in memory, or in a non-transitory computer-readable storage medium configured to carry out the transaction schemes (e.g., in a self contained silicon device, a solid state memory, an optical disc, a magnetic disc, etc.). 
     Distribution of Data to Mobile Device Prompted by Acoustic Stimuli 
       FIG. 17  illustrates a block diagram of an advertising system  1800  for distributing context based advertising on a mobile device prompted by acoustic based stimuli, according to an exemplary embodiment of the present disclosure. Herein, “acoustic” is intended to include its broadest meaning with respect to sound, both audible by humans and beyond human hearing, both at frequencies above and below normal human prescription. The advertising system  1800  includes an acoustic emitting device  1810 , acoustic signal  1820 , and acoustic receiving device  1830 . 
     The acoustic emitting device  1810  is configured to emit a high frequency acoustic stream. A high frequency acoustic steam is a stream of sound that is outside the audible spectrum of a human, or greater than 21,000 Hz. The acoustic emitting device  1810  may be any device capable of transmitting a suitable high frequency acoustic stream, such as a radio, television, computer, or a mobile device, for instance. The acoustic signal  1820  is emitted from the acoustic emitting device  1810 . In an exemplary embodiment, the acoustic signal  1820  may be embedded into a visual or acoustic based advertisement, such as a poster or window display. In accordance with an exemplary embodiment, the acoustic signal may include encoded data, such as a unique reference to a product or a stream of binary data. In one exemplary embodiment, the encoded data is a pay code representation of a transaction skeleton as described above. Any method of data encoding that is suitable for the transfer of data as an acoustic signal can be used, such as amplitude-shift keying or frequency-shift keying, for example. 
     The acoustic receiving device  1830  is configured to recognize the acoustic signal  1820  through the included acoustic receiver  1840 . The acoustic receiving device  1830  can be any device capable of performing the functions as discussed herein, such as a mobile device or laptop computer, for example. In an exemplary embodiment, the acoustic receiving device is a cellular phone and/or smart phone, which in some embodiments, may also be capable of reading machine-readable representations of data, such as a bar code. The included acoustic receiver  1840  is any device capable of recognizing the acoustic signal  1820 , such as a microphone. The acoustic receiving device  1830  also includes an analog-to-digital converter  1850 , a processing device  1860 , and a database  1870 . 
     The analog-to-digital converter  1850  converts the recognized acoustic signal from an analog signal into a digital signal. The processing device  1860  then analyzes the converted acoustic signal and decodes the encoded data in the acoustic signal. The processing device  1860  can include any device capable of performing the functions discussed herein, such as a central processing unit (CPU) or a plurality of CPUs. In one exemplary embodiment, the decoded data itself is displayed on the acoustic receiving device  1830 . The decoded data can include product information, news items, coupons, special offers, or any other information that could benefit a consumer. In one exemplary embodiment, the decoded data is a machine-readable code representation of data, such as a bar code (e.g., a QR code) containing a transaction skeleton for a financial transaction. The acoustic receiving device  1830  may also be used in order to carry out the corresponding financial transaction as described above. 
     In one exemplary embodiment, the decoded data is a unique reference to a product stored in the database  1870 . The database  1870  can be included in the acoustic receiving device  1830 , but may also be external to the device and accessed via a communication network such as a local area network (LAN) or the Internet. The database  1870  may contain product information, such as a product summary, product specifications, retail price, sizing information, etc. In an exemplary embodiment, the database  1870  contains merchant and purchasing information corresponding to the product. The information included in the database  1870  corresponding to the product may be displayed to the consumer on the acoustic receiving device  1830 . 
     Exemplary Method of Acoustic-Based Distribution 
       FIG. 18  is a flowchart that illustrates a method  1900  for distributing context based advertisements on a mobile device via the system of  FIG. 17 , according to an exemplary embodiment of the present disclosure. 
     In step  1902 , the acoustic receiving device  1830  recognizes an analog acoustic signal. The analog acoustic signal contains a high frequency acoustic stream of at least 21,000 Hz, outside the audible spectrum of a human. In step  1904 , the analog-to-digital converter  1850  converts the analog acoustic signal to a digital acoustic signal. In step  1906 , the processing device  1860  analyzes the digital acoustic signal to obtain encoded data, and decodes the data in step  1908 . Encoding schemes such as amplitude-shift keying or frequency shift keying can be used. In accordance with an exemplary embodiment, the data decoded in step  1908  can be a unique reference to a product. In one exemplary embodiment, the data decoded is a machine-readable code representation (e.g., a QR code) of a transaction skeleton. 
     In step  1910 , the decoded data is used to locate product information in a database  1870  and retrieve the information. The information may include, for example, a product description, a product summary, merchant information, retail price for the product, etc. In an exemplary embodiment, the information allows the consumer to immediately purchase the product from a predetermined merchant or to choose from a list of merchants who sell the product. In another exemplary embodiment, a financial transaction is initiated based on a transaction skeleton represented in the decoded data. Product information retrieved may also include coupons, special offers, news items, or other information that may be beneficial to a consumer. In step  1912 , the information is displayed (e.g., presented) to the consumer on the acoustic receiving device  1830 . 
     In one exemplary embodiment, in step  1912  a financial transaction can be initiated based on the information retrieved from the database  1870 . For example, the consumer&#39;s mobile device may initiate a transaction from a specific merchant for a specific product as specified in the database  1870 , e.g., by connecting to a transaction website on which the product can be purchased. In one exemplary embodiment, if the database  1870  contains only product information, the consumer&#39;s mobile device may display a list of multiple merchants with which to initiate a financial transaction for the product, or may initiate a transaction with a predetermined merchant. In some exemplary embodiments, the decoded data may be a pay code, and the acoustic receiving device  1830  may be payer device  10 A. 
     The exemplary system and method for distributing data prompted by acoustic based stimuli has a wide variety of applications, not limited to advertising or consumer products. For instance, the system and method has additional educational applications, such as for use in museums. An acoustic emitting device can be placed near exhibits or points of interest in a museum, and the guest&#39;s mobile device used as an acoustic receiving device. The acoustic emitting device may emit a high frequency acoustic stream to an area near the exhibit, and when the mobile device recognizes the stream can display to the guest information related to the exhibit they are viewing. 
     The use of high frequency acoustic streams can also be used to assist with the visually impaired. Placement of acoustic emitting devices and the use of sound or vibration functions when a cellular phone or other mobile device recognizes an acoustic stream may notify a visually impaired person of an obstacle or assist with navigation of an unfamiliar area. 
     Voice and Human Based Gesture Actions 
       FIG. 19  shows a system  2000  for purchasing products or services through the use of voice and human based gesture actions that includes a human interaction device  2010 , display device  2020 , and processor device  2030 . 
     Human interaction device  2010  of the system  2000  is a device that is configured to read voice and/or human based gesture actions, e.g., a microphone, camera, or a hybrid device (such as Microsoft® Kinect™ or PlayStation® Eye™). The human interaction device  2010  may transmit voice and/or human based gesture action data to the processor device  2030 . Transmission can be through a physical connection, such as a coaxial cable, or through a communication network, such as a local area network (LAN) or the Internet, for instance. 
     The display device  2020  is a device configured to display visual data to a consumer, such as a television or computer monitor. In some embodiments, the human interaction device  2010  is integrated with the display device  2020 , such as in a computer monitor with built-in webcam. The processor device  2030  is configured to receive voice and/or human based gesture action data from the human interaction device  2010  and to transmit display data to the display device  2020 . The processor device can be, for example, a set-top box, a gaming device, or a DVD or Blu-Ray player, for example. In some embodiments, the display device  2020  and the processor device  2030  are integrated as a single apparatus, such as in a smart television or a computer. In some embodiments, the system  2000  is contained in a single apparatus, such as a laptop computer with a built-in webcam. 
     Data that is transmitted from the processor device  2030  to the display device  2020  may contain event data. Event data may be included in video data, acoustic data, or in a combination of both acoustic and video data. Event data may be visible or audible to a consumer (e.g., in a visual advertisement) or may be invisible to a consumer, such as by including event data in a vertical blanking interval of a video transmission. Transmission of event data may include any type or manner of transmission suitable for the systems and methods and discussed herein. Information included in the event data may include product information, transaction identification, machine-readable code, merchant information, etc. 
       FIG. 20  is a block diagram illustrating the processor device  2030  according to an embodiment of the disclosed system. The processor device  2030  includes a communication interface device  2110 , processor  2120 , read-only memory  3130 , random access memory  2140 , and hard disk drive  2150 . 
     The communication interface device  2110  provides one or more communication paths from the processor device  2030  to and from other systems. The communication interface device  2110  is configured to at least receive voice and/or human based gesture data from the human interaction device  2010  and send visual data to the display device  2020 . 
     The processor  2120  is a device suitable for performing the functions discussed herein, such as a central processing unit (CPU) or a plurality of CPUs. The processor may operate via implementations of hardware, of software, or of a combination of both hardware and software. For example, the processor may utilize software stored in read-only memory  2130  or hard disk drive (computer-readable medium)  2150 . The processor is configured to analyze data, such as video and human based gesture data that can be stored, for example, in random access memory  2140  or computer-readable medium  2150 . Computer-readable medium  2150  may be any type of non-transitory computer-readable medium suitable for performing the functions discussed herein, e.g., hard disk drive, solid state drive, compact disc, digital versatile disc, etc. 
     Exemplary Method of Voice or Gesture-Based Transacting 
       FIG. 21  is a flowchart illustrating a method  2200  for purchasing products or services through the use of voice and/or human based gesture actions. 
     In step  2202 , the processor device  2030  monitors for event data that corresponds to a possible consumer purchase (e.g., product information, product description, merchant information, etc.). In one embodiment, event data may be transmitted to the processor device  2030  at the same time as an advertisement to be displayed. In another embodiment, event data may be stored in a database that can be external to, or included as part of, the processor device  2030 . 
     In step  2204 , the processor device  2030  determines if event data has been received. If there has been no receipt of event data, it returns to step  2202  where it continues to monitor for event data. If the event data has been received, the processor device  2030  determines if the corresponding event is occurring. The corresponding event may be, for example, a commercial, a movie, or a sporting event. If the event is not occurring, it returns to step  2202  and continues to monitor for data. If the event is occurring, it means that there is currently at least one product eligible for a transaction. In one embodiment, this is signified by an icon on the display device  2020  to notify the consumer that product(s) are available for purchase through voice or gesture based actions. 
     If the event is occurring ( 2206 ), the processor device  2030  monitors for voice and gesture data in step  2208 . Voice and gesture data can include, for example, the consumer speaking a specific, preset phrase, or by waving the consumer&#39;s left hand in the air. If voice or gesture data is not detected in step  2208 , then the processor device returns to step  2206  to determine if the event is still occurring. If voice or gesture data is received, then it proceeds to step  2212  and initiates the transaction. 
     In an exemplary embodiment, once the transaction has been initiated, a pay code may be transmitted (e.g., sent) to the consumer&#39;s mobile device (e.g., payer device  10 A) or displayed on the display device  2020 . The consumer can then read (e.g., scan) the pay code and carry out the financial transaction as described above. 
     The system may also be configured to utilize a consumer&#39;s electronic wallet. An electronic wallet if a safe and convenient method for consumers to engage in electronic purchases, such as by securely saving payment information for one or more methods of payment (e.g. a credit card, an electronic check, an ACH transfer from a bank account, or additional payment methods such as PayPal, etc.). It can also store other useful information such as billing or shipping addresses. A consumer&#39;s electronic wallet can be associated with them in the system and readily used when they initiate a transaction. 
     In some instances, multiple consumers may utilize a single system for making purchases using voice or human based gesture actions. In these instances, biometric data can be utilized to distinguish one consumer from another. For example, the consumer&#39;s vocal patterns can be used as an identifier when the human interaction device  2010  is a microphone. If the human interaction device  2010  is a camera, facial or retinal recognition can be used as an identifier. In some instances, multiple identifiers may be used for security reasons, such as requiring both vocal and retinal identification. Additionally, the system can be configured to require a consumer personal identification number (PIN) to complete a transaction. 
     When a consumer initiates a transaction, the system may display (e.g., on the display device  2020  or on the consumer&#39;s mobile device) purchasing information for the consumer that corresponds to the specific product and merchant in the advertisement. In one exemplary embodiment, the system may display a machine-readable pay code on the display device  2020 . In instances where multiple products are advertised, or when a product is advertised not tied to a specific merchant, a list of products or merchants may be displayed to the consumer. Additional voice or human based gesture actions may be used in order to select among the products or merchants. For example, a cursor can be displayed on the display device  2020  that may be moved through arm gestures or by vocal commands, or the choices may be displayed in a list with the consumer speaking or gesturing their choice in the list (e.g., holding up nine fingers for the item listed ninth). Such a selection method may also be used for the consumer to select between multiple methods of payment or between multiple shipping addresses. 
     Location- and History-Based Distribution of Offers to a Mobile Device 
       FIG. 23  illustrates a block diagram of a system for distributing offers to a mobile device. The system may include an offer server  2410 , a mobile device  2420 , a merchant  2430 , and a cellular network tower  2440 . 
     The offer server  2410  may be configured to identify the geographic location of the mobile device  2420 . The identification of the geographic location of the mobile device  2420  may be obtained by using, for example, the Global Positioning System (GPS), cellular network tower triangulation (commonly known as Assisted GPS), or Wi-Fi or wireless networks, or any combination thereof. 
     By way of example, the geographic location of the mobile device  2420  may be obtained by using GPS, such as through GPS application  2422  included on the mobile device  2420 . The mobile device  2420  may be in communication with at least one cellular network tower  2440  in order to determine its location. In an exemplary embodiment, the mobile device  2420  is in communication with at least three cellular network towers  2440  for the purposes of triangulation of the mobile device  2420 . In one embodiment, the merchant  2430  may include a wireless network  2432 . In such an embodiment, the geographic location of the mobile device  2420  may be identified when the mobile device  2420  connects or is otherwise in communication with the wireless network  2432 . Other suitable methods of identification of the geographic location of the mobile device  2420  will be apparent to persons having skill in the relevant art. 
     The offer server  2410  may also be configured to identify the geographic location of the merchant  2430 , or may store location information of the merchant  2430  in a database (not shown) either included in the offer server  2410 , external to the offer server  2410 , or in combination thereof. 
     The offer server  2410  may also include a user accounts database  2412  and an offer database  2414 . These databases may be included as part of the offer server  2410 , may be stored externally to the offer server  2410 , or in combination thereof. The user accounts database  2412  may include information associated to a user of the mobile device  2420 . The information stored in the database  2412  may include a history of financial transactions between the user of the mobile device  2420  and the merchant  2430  if elected by the user. The financial transaction history may be minimal (e.g., only the existence of past transactions) or may include the number of transactions, the amount of each transaction, the time and date of each transaction, or the goods or services purchased in each transaction, for example. 
     The offer database  2414  may include at least one offer, which the offer server  2410  may be configured to distribute to the mobile device  2420 . The offer may only be distributed to the mobile device  2420  if the offer server  2410  identified at least one previous financial transaction between the user of the mobile device  2420  and the merchant  2430  stored in the user accounts database  2412 . The offer may be for goods or services, and may be associated with the merchant  2430 . The offer may also be an advertisement or a machine-readable code (e.g., a bar code) that when read by the mobile device  2420  initiates a financial transaction with the merchant  2430  for goods or services. 
     The merchant  2430  may be proximate to the geographic location of the mobile device  2420  identified by the offer server  2410 . The proximity of the merchant  2430  may vary from merchant to merchant, offer to offer, or user to user. The proximity may also be based on the number of additional merchants nearby. For example, if the merchant  2430  is the only merchant in a shopping center, offers associated with the merchant may be distributed if the mobile device  2420  is identified as being within one mile of the merchant, but if the merchant is located within a shopping mall that includes a plurality of other merchants, the mobile device  2420  may be required to be within five hundred feet of the merchant  2430  before an offer that is associated with the merchant  2430  may be distributed to the mobile device  2420 . 
     Exemplary Method for Distribution of Location- and History-Based Offers 
       FIG. 24  is a flow diagram illustrating an exemplary method for distributing offers to a mobile device in accordance with exemplary embodiments. 
     In step  2502 , the offer server (e.g., offer server  2410 ) may identify a geographic location of a mobile device (e.g., mobile device  2420 ) associated with a user. In one embodiment, the offer server uses GPS, Assisted GPS, wireless network discovery, or a combination thereof. In step  2504 , the offer server may identify at least one merchant (e.g., merchant  2430 ) proximate to the geographic location. 
     In step  2506 , the offer server may identify, in a user account associated with the user (e.g., stored in user accounts database  2412 ), at least one previous transaction between the user and the at least one merchant. In one embodiment, the server must identify at least three previous transactions between the user and the at least one merchant. In step  2508 , an offer is distributed to the mobile device. In one exemplary embodiment, the offer is an offer for goods or services and the offer is associated with the at least one merchant. In one embodiment, the mobile device is a mobile communication device configured to read machine-readable code, and the offer is a machine-readable code that initiates a financial transaction with the at least one merchant when read by the mobile device. 
     Where methods described above indicate certain events occurring in certain orders, the ordering of certain events may be modified. Moreover, while a process depicted as a flowchart, block diagram, etc. may describe the operations of the system in a sequential manner, it should be understood that many of the system&#39;s operations can occur concurrently. For example, although the multiple payer pay code flow ( FIGS. 7A-7C ) is disclosed and illustrated as being configured to have payer device  10 A receive the transaction details and pay prior to payer device  10 B, payer device  10 B can receive and pay prior to payer device  10 A as well. 
     Techniques consistent with the present disclosure provide, among other features, systems and methods for distributing content to devices, initiating financial transactions, processing electronic financial transactions using a payer device and pay codes, and indirectly controlling websites. While various exemplary embodiments of the disclosed system and method have been described above it should be understood that they have been presented for purposes of example only, not limitations. It is not exhaustive and does not limit the disclosure to the precise form disclosed. Modifications and variations are possible in light of the above teachings or may be acquired from practicing of the disclosure, without departing from the breadth or scope.
