     To assemble the information for the data packet(s), the data manager  92  may be communicatively coupled to one or more databases. For example, the data manager  92  may be coupled to a manufacturer database  94 . The manufacturer database  94  may hold manufacturer related information for a wide variety of products. For example, the manufacturer database  94  may hold information such as brand name, model number, serial number, UPC code, product types or classifications, product descriptions, suggested retail prices, stores where the product may be available, a media file regarding the product, a web page address for obtaining more information about the product or purchasing the product, among other things. To obtain the appropriate manufacturer related data for the product  78 , the data manager  92  may cross reference the product identifier with data in the manufacturer database  94 . To be included in the manufacturer database, a manufacturer may pay a fee to the manufacturer of the device  10 , for example, to upload the relevant product information related to the manufacturer database  94 . 
     The data manager  92  may also be coupled to a retailer database  96  which may hold retailer specific product information. As with the manufacturer database, the retailer database  96  may hold information that pertains to the product itself. Moreover, the retailer database  96  may hold retailer specific product information such as the name of the retailer, store locations, the actual retail price of a product, a retailer webpage address, a retailer telephone number(s), etc. Additionally, some database entries may be flagged to indicate some feature of the entry, such as whether the data applies to in-store or Internet purchases and whether a special promotion exists in relation to the product, etc. The data manager  92  may obtain appropriate retailer-related data for the product  78  by cross-referencing the product identifier with data in the retailer database  94 . In some embodiments, a retailer may pay a fee to the manufacturer of the device  10 , for example, to be included in the retailer database  94 . 
     In some embodiments, both the manufacturer database  94  and the retailer database  96  may contain advertisements that may be sent to the electronic device  10  in response to the information request packet. Such advertisements may include product related data, and/or media files such as picture, video, and audio files. 
     The data manager  92  may also be communicatively coupled to a consumer database  98  which may hold information related to the user of the electronic device  10 . For example, the consumer database  98  may include a preference profile of the user of the electronic device  10 . The preference profile may include such information as specific retailers that the user prefers and/or specific brands of products that the user prefers. The consumer database  98  may be populated based on information exchanges between the data manger  92  and the electronic device  10  which may indicate the shopping habits of the user. Additionally, the consumer database  98  may also be populated by personal preferences identified by the user, an embodiment of which is described in relation to  FIG. 5 . In other embodiments, the information contained in the consumer database  98  may also included in the memory of the electronic device  10  itself. 
     In some embodiments, the data manager  92  and the databases  94 ,  96 , and  98  may be a part of a system owned and operated by a single entity, such as a manufacturer of the handheld electronic device  10 . In this embodiment, the operator may populate the manufacturer database  94  and the retailer database  96  with information provided to the operator by various product manufacturers and retailers in exchange for a fee. 
     The content of the data packets compiled by data manager  92  may depend on the information provided by the electronic device  10  in the information request packet. For example, if the user is requesting information regarding a product per se, such as specifications, suggested retail price, warrantee information, etc., the information request packet may include a single product identifier and request ID that indicates a request for manufacturer-specific product information. In response, the data packet may include information from the manufacturer database  94  for the one product identified. 
     For another example, if the user requests retail pricing information for a particular product, the electronic device  10  may send a product identifier, a geographical location of the electronic device  10 , retailer preferences, and/or a request ID indicating a request for pricing information for various retailers. In response, the data packet may include retail prices for one or more preferred retailers within a specified travel distance from the electronic device  10 . 
     Examples of data exchanges between the electronic device  10  and the data manager  92  will be further described in relation to the shopping features of the electronic device  10 , as illustrated in  FIGS. 5-20 . It will be appreciated that the information exchanged between the electronic device  10  and the data manager  92  will depend on the way that processing tasks are divided between the electronic device  10  and the data manager  92 . For example, if the retailer preferences are stored in the consumer database  98 , the electronic device  10  may send a user ID that allows the data manager to retrieve the proper retailer preferences. However, if the retailer preferences are stored on the electronic device  10 , the electronic device  10  may send all of the retailer preference data to the data manager  92  instead of or in addition to the user ID. It is intended that embodiments are not limited to a particular division of processing tasks between the electronic device  10  and the data manager  92 . 
     Furthermore, in some embodiments, the data retrieved by the data manager  92  may be used to derive secondary information that may be useful to a user. For example, product pricing data may be used to calculate a total price for several products. For another example, retailer locations may be used to calculate distances between the user and the retailer. For yet another example, the product pricing data may be used to generate priority or relevance information, which may effect how the data is presented to a user. It is important to note that the secondary information, which will be described further below, may be derived by the data manager  92  and included in the data packet or may be derived by electronic device  10 . Therefore, it will be appreciated that although certain information may be described below as being calculated by either the electronic device  10  or the data manager  92 , the present embodiments are not intended to be limited by whether a particular calculation is performed by the electronic device  10  or the data manager  92 . 
       FIGS. 5-20  further detail the capabilities of the electronic device  10  and the data transfer system  76  by illustrating various screens that the user of the electronic device  10  may encounter while using the various shopping related features of the electronic device  10 . The functionality described may be achieved with a wide variety graphical elements and visual schemes. Therefore, the present embodiments are not intended to be limited to the precise user interface conventions adopted herein. Rather, embodiments may include a wide variety of user interface styles. Indeed, the presently disclosed user interface conventions are based on Apple&#39;s iPhone for the convenience of the reader, although other user interface conventions could readily be used to carry out the present techniques. 
       FIG. 5  illustrates a method of using the electronic device  10  to specify one or more preferred retailers. In some embodiments, selection of the shopping icon  34  ( FIG. 1 ) may advance the user to a shopping screen  100 , which may serve as a gateway to the shopping features of the electronic device  10 . The shopping screen  100  may include several graphical elements such as buttons  102 ,  104  and  106  and  107 , all of which allow the user to access the shopping feature indicated. As will be explained further below, embodiments allow the user to compare product prices between various retailers. To narrow the search, the user may be prompted to specify a particular retailer or group of retailers that the user prefers. To provide the user a quick way to specify one or more retailers when prompted, the electronic device  10  may allow the user to create and save one or more lists of preferred retailers ahead of time. To access this feature the user may select the retailer preferences button  106  from the shopping screen  100 . 
     Upon selection of the retailer preferences button  106 , the user may be advanced to a retailer preferences screen  108 . The retailer preferences screen  108  may include a retailer category list  110  that includes several retailer categories  112  pertaining to any type of retail product, such as groceries, sporting goods, clothing, electronics, home appliances, furniture, office supplies, automobiles, etc. As shown in the edit category screen  120 , the retailer categories  112  may include a list of retailers that carry items within that particular category. In some embodiments, one or more of the retailer categories  112  may be preloaded by a manufacturer of the electronic device  10 , and one or more categories may be custom created by the user. Categories may be deleted by selecting an individual category within the retailer category list  110  and touching the delete category button  114 . New categories may be created by selecting the new category button  118 . Categories may be edited and customized by selecting the retailer category  112  in the retailer category list  110  and pressing the “edit category” button  116 . 
     The “edit category” screen  120  includes a retailer list  122  which includes several retailer listings  124 . In addition to the name of the retailer, each retailer listing  124  also includes one or more icons. For example, a retailer listing  124  may include a building icon  126  that indicates that the retailer listing pertains to a physical store location. The retailer listing  124  may also include an on-line icon  128  that indicates that the retailer listing  124  pertains to on-line shopping. The presence of a building icon  126  or an on-line icon  128  may indicate the preference of the user regarding whether they wish to purchase items from that particular retailer on-line or at the store. The retailer listings  124  included within a retailer category  110  may be preloaded by the manufacturer of the electronic device  10 , possibly in exchange for a fee from the retailers, and may also be edited by the user to include only those retailers that the user frequents. 
     The user may remove a retailer by selecting a retailer listing  128  in the retailer list  122  and selecting the remove retailer button  130 . To add a retailer the user may by select the “add retailer” button  132 , which may advance the user to the add retailer screen  134  and may also cause the electronic device  10  to send an information request to the data manger  92 , requesting a list of retailers from the retailer database  96 . 
     The add retailer screen  134  may include a retailer list  122 , which may include all the retailers contained within the retailer database  96  or may be narrowed to provide a more focused set of relevant retailers. For example, the retailer list  122  may narrowed to include only those stores within a specified radius, geographic region, zip code, etc. For example, the radius may be relative to the geographical location of the electronic device  10  or a geographical location specified by the user. Accordingly, the add retailer screen  134  may include a search radius indicator  136  by which the user may specify the search radius used to acquire the retailer list  122 . The add retailer screen  134  may also include buttons  138  for increasing or decreasing the search radius. 
     As in the edit category screen  120 , the add retailer screen  134  may also include the building icon  126  and the on-line icon  128 . However, in the add retailer screen  134 , the building icon  126  and the on-line icon  128  indicate whether the retailer exists as a physical store and/or whether it has an on-line shopping presence. To add one of the retailers from the retailer list  122  to the retailer category  112 , the user may select the retailer in the list and press the add button  140 , which advances the user to the add screen  142 , which includes a message to the user requesting confirmation that the user would like to add the selected retailer to the retailer list. The add screen  142  may also include check boxes  144  which are adjacent to and correspond with the building icon  126  and the on-line icon  128 . The user may select or de-select the check boxes  144  to indicate whether the user wishes to add the retailer as a “brick-n-mortar” retailer and/or an on-line retailer. 
     Selection of one of the confirmation buttons  146  may add the retailer selected to the retailer category  112  and return the user back to the edit category screen  120  or the add retailer screen  134 . The significance of the retailer preferences will be better understood with reference to the price comparison features of the electronic device  10  described further below in relation to FIGS.  11  and  18 - 20 . 
     Turning first to  FIGS. 6-10  various techniques for using the electronic device  10  to identify a product are illustrated.

The recent scan entries  208  may be loaded into the storage memory  58  of the electronic device  10  each time that the user scans an item. In this way, the user will have a running history of all scanned items and may return to them at any time. The user may remove items from the list by selecting the “remove from list” button  210 . By selecting a recent scan entry  208 , the user may then advance to the scanned item screen  174 . 
     As mentioned above, once a product identifier has been obtained, the electronic device  10  may be used to obtain product information that may help a user to make the best possible purchase. Turning to  FIG. 11 , and the scanned item screen  174 , a method of using the electronic device  10  to compare product prices for several retailers is depicted in accordance with an embodiment. From the scanned item screen  174 , the user may select the “compare prices” button  182  to advance to the consumer prices screen  212 . The consumer prices screen  212  may include a user instruction message  164  requesting the user to select one or more retailer categories  112 . As discussed above in relation to  FIG. 5 , each of the retailer categories  112  corresponds with a list of retailers that have been pre-selected by the user or pre-set at the factory. In selecting one or more retailer categories, the user selects the retailers that will be included in the price comparison. 
     After the user has selected one or more of the retailer categories  112 , the user may advance to the prices screen  218  by selecting the “prices” button  216 , at which time, the electronic device  10  may send an information request packet to the data manager  92 , as discussed above. The information request packet may include the product identifier, a user identifier, the geographical location of the user, and/or the list of retailers corresponding with the selected retailer categories  112 . The data manager  92  may then compile one or more data packets to send back to the electronic device  10  by cross-referencing the product identifier with the information in the retailer database  96 . In some embodiments, the data manager may also cross-reference the user identification with the consumer database  98  to obtain preferences of the user. 
     The data packets compiled by the data manager  92  may include a list of retailers that sell the scanned item, along with one or more retailer information packets associated with each retailer. The retailer information packets may include such information as the store location, the price of the item at that retailer, the address of the retailer, a picture or icon or a segment of video pertaining to the retailer, an audio file pertaining to the retailer, a phone number of the retailer, an indication of whether the data applies to in-store purchases or on-line purchases, an indication of whether a special promotion may exist with regard to the item or similar items, and any other information that may be useful to the user. 
     If a large number of relevant retailers are found by the data manager  92 , the data manager  92  may select a limited number of retailers to include in the data packets, depending on the likelihood of user interest in a particular retailer. The user may, therefore, specify a maximum number of hits that the user wishes to receive. The likelihood of user interest may be determined by the data manager  92  by using various criteria, such as retailer prices, location of the retailer, and/or user preferences. For example, the data manager  92  may select a number of retailers with the lowest prices available for the selected item. For another example, the data manager  92  may select a number of retailers which are closest to the geographical location of the user. For yet another example, the data manager  92  may select retailers for which the consumer has previously requested information, according to records stored in the consumer database  98 . In one embodiment, the user may select or pre-select the manner in which retailers are displayed to the user. 
     Additionally, depending on the request ID sent by the electronic device  10 , the data packets may include only a select portion of the retailer information available in the retailer database  96 . For example, the data packets may include only the information that will be displayed in the prices screen  218 , such as retailer name, retailer price and store location. 
     After the device  10  receives the data packet(s) from the data manager  92 , the device  10  may advance the user to the prices screen  218 . As in the scanned item screen  174 , the prices screen  218  may include a product picture  176  and product information elements  178 . The prices screen  218  may also include a retailer prices list  220  with one or more retailer price entries  222 . Each of the retailer price entries  222  may include the name of the retailer as well as one or more retailer information elements  224 . For example, retailer information elements  224  may include an indication of the distance between the current location of the user to the location of the retailer, and/or the distance from the retailer to a home location specified by the user. The retailer information element  224  may also include the retail price offered by the retailer for the scanned item  78 . The prices screen  218  may also include one or more “sort” buttons  226  which may allow the user to alter the appearance of the retailer prices list  220 . For example, the user may use the sort buttons  226  to sort the retailer prices list according to the retailer&#39;s distance or according to price. 
     By selecting a retailer price entry  222 , the user may advance to the retail information screen  228 . As discussed above, in some embodiments, the electronic device  10  may send another information request to the data manager  92  to obtain more detailed information pertaining to the selected retailer. In other embodiments, the more detailed information may have already been obtained during the previous information request. The retailer information screen  228  may include a building icon  126  and/or an on-line icon  128  indicating, as stated above, whether the particular retailer selected is a brick-and-mortar retailer and/or whether the retailer provides on-line shopping capabilities. The retailer information screen  228  may also include a retailer picture  230 , which may be downloaded from the retailer database system  96 . The retailer database screen  228  may also include a segment of video pertaining to the particular retailer. The retailer information screen  228  may also include a retail information window  232 , which may hold a variety of information of interest to the user, such as the distance between the retailer and the user and/or the price offered by the retailer for the scanned item  78 . 
     The retailer information screen  228  may also provide additional shopping-related features, as illustrated in  FIG. 12 . For example, by selecting a “map” button  234 , the user may advance to a map screen  240 . The map screen  240  may be created by a mapping application included in the electronic device  10  or may be an on-line mapping website running in the web browser of the electronic device  10 .

Moreover, the map screen  240  may also include a map element  246 , showing a retailer location with a destination icon  248  and showing the current location of the user with a current location icon  250 . In some embodiments, the map element  246  may also include a trace depicting a route between the user&#39;s current location and the selected retailer. Additional features of a mapping application may also be included, such as route guidance. 
     As another example of a feature available at the retailer information screen  228 , the user may also select a “promotions” button  236  to advance to the promotions screen  252 . The promotions screen  252  may serve as a medium by which the selected retailer may inform the consumer about special deals that the retailer is featuring. The promotions screen  252  may be a part of the shopping application of the electronic device  10 , in which case, the promotional information may be stored in the retailer database  96  and sent to the device  10  by the data manager  92 . Alternatively, selection of the “promotions” button  236  may direct the user to an on-line webpage of the retailer through a web application of the electronic device  10 , in which case, the web address may be stored in the retailer database. The promotions screen  252  may include an advertisement window  254  which may display any type of media, including still pictures or video. The promotions screen  252  may also include a promotions list  256  with listings of special deals available from the retailer. Entries within the promotions list  256  may be product entries within the retailer database  96  that have been flagged as special promotions. In some embodiments, an audio and/or video file uploaded from the retailer database  96  may be played in conjunction with the promotions screen  252  or in conjunction with a selection of the user within the promotion screen  252 . 
     The promotions screen  252  may also provide the option of retrieving an “electronic coupon” to be used at a particular retailer location or online. For example, the promotions list  256  may include a listing for a coupon, which the user may select to download the coupon to the electronic device  10 . Upon purchasing the featured item, the user may upload the coupon from the electronic device  10  to the retailer to realize the savings advertised. If the user uses the coupon in the store, the retailer may have a corresponding electronic device at the cash register for communicating with the electronic device  10 , such as through NFC communications, for example, so that the coupon may be transferred from the electronic device  10  to the retailer. 
     As another example of a feature that may be available from the retailer information screen  228 , the user may also select the “buy now” button  238  to advance to the on-line shopping screen  260 . The on-line shopping screen  260  may be created by the shopping application of the electronic device  10 . Alternatively, user selection of the “buy now” button  238  may direct the user to an on-line shopping webpage of the retailer through a web application of the electronic device  10 . In addition to the product picture  176  and production information elements  178 , the on-line shopping screen  260  may also offer the user another on-line shopping feature. For example, the user may add the scanned item to a shopping cart by selecting the “add to cart” button  262 . For another example, the user may advance to a purchasing window by selecting the “check out” button  264 . For yet another example, the user may view other available products by selecting the “more shopping” button  266 . Selection of the “more shopping” button  266  may advance the user to a home page of the retailer&#39;s on-line shopping website. Alternatively, selection of the “more shopping” button  266  may advance the user to another screen within the shopping application that features additional items available from that retailer, in which case, the electronic device  10  may send another information request to the data manager  92 , requesting a list of other products available from the selected retailer. 
     Turning now to  FIGS. 13A ,  13 B, and  14  methods of using an electronic device  10  to acquire and generate consumer information for a selected product are shown. Turning specifically to  FIG. 13A  and returning to the scanned item screen  174 , a user may select the “consumer information” button to advance to the consumer information screen  268 . The consumer information screen  268  may serve as a gateway to the consumer information features of the electronic device  10 . For example, the consumer information screen  268  may allow a user to receive extensive information about product features by selecting the “features” button  270  and to obtain product ratings by selecting the “ratings” button  272  or the “consumer guide” button  274 . 
     Regarding the “features” button  270 , the user may select this button to advance to the product features screen  276 . The product features screen  276  may include a product features list  278  that includes product feature entries  280 . Selection of the “features” button  270  may initiate an information request by the electronic device  10 . In accordance with the information request, the data manager  92  may assemble a data packet containing information obtained from the manufacturer database  94 , such as product type, product dimensions, product weight, product pricing and other product specifications. The information included in the data packet may be product-type specific, such as screen size in the case of a television. 
     Turning to  FIG. 13B  and returning to the consumer information screen  268 , a user may select the “consumer guides” button  274  to advance to a consumer guides selection screen  308 . The consumer guides selection screen  308  may allow the user to acquire information from professional consumer guide organizations. Accordingly, the consumer guides selection screen  308  provides a consumer guide list  310  that includes one or more consumer guide entries  312 . Selection of a particular consumer guide entry  312  will provide the user with the quality or rating information available from that particular organization for the scanned item. The consumer guide entries  312  may be preloaded into the device  10  at the factory and the user may also customize the consumer guide list  310  by using either the “add guide” button  314  or the “remove guide” button  316 . 
     Selection of a consumer guide entry  312  may advance the user to a consumer guide screen  318 , which details the consumer guide information available for the scanned item. The consumer guide screen  318  may include a data window  320  that provides any information that the consumer guide may provide for the scanned item. For example, the data window  320  may include such things as an overall rating of the product, an average retail price, and/or an indication of whether the consumer guide considers the product to be a worthwhile purchase. The consumer guide screen  318  may include a rating information list  322  with rating information entries  324 . The rating information entries  324  may provide detailed information related to features of the product that have been tested or for which repair information or consumer opinions have been compiled. The consumer guide screen may also include a “read review” button  326  which may allow a user to read a professional review of the product. 
     Turning now to  FIG. 14  and returning to the consumer information screen  268 , the user may select the “ratings” button  272  to advance to the consumer ratings screen  282 . The consumer ratings screen  282  may be used to access consumer ratings that have been compiled by other users of other electronic devices. Therefore, the consumer ratings screen  282  may include a consumer ratings list  284  which includes consumer ratings entries  286 . The consumer rating entries  286  may identify a rater by displaying a unique user name and may show a segment of the rater&#39;s comments as well as an overall rating given by the rater. 
     In some embodiments, the electronic device  10  may also include a tool for users to submit a product rating. As shown in  FIG. 14 , selection of the “rate this item” button  288  will send the user to a rate item screen  290 . The rate item screen  290  may include a rating selection element  294 , such as a slider bar, and a rating indicator  292  for indicating the selected rating. To enter a comment, the rate item screen  290  may also include a comment window  296  and a keyboard  298 . After submission of the rating and comment, the submission may be saved to a database that is accessible by other users, such as the consumer database  98 , or some other database communicatively coupled to the data manger  92 . In some embodiments, a user of the electronic device  10  may incur a small fee for obtaining a product rating, and/or may obtain a credit by submitting a product rating. 
     Furthermore, in some embodiments, the product information features described above may also include a side-by-side comparison of similar products. For example, in the consumer guide screen  318 , consumer guide ratings for the scanned product may be displayed along with consumer guide ratings for products comparable to the scanned product. For another example, in the product features screen  276 , product features for the scanned product may be displayed along with product features of similar products. By providing information on more than one product, the user may make a quick side-by-side comparison of similar products. 
     In addition to obtaining information for a single product, the electronic device  10  may also include methods of adding a product to a shopping list. Methods of generating and using a shopping list within the electronic device  10  are shown in  FIGS. 15-20 . As will be described further below, shopping lists may be entered into the electronic device  10  manually or by scanning a product as described above. Additionally, items in the shopping list may be associated with a product identifier or may simply be a generic or shorthand product name created by the user. The shopping lists may be used, in some embodiments, to remind the user to acquire certain items while at a store. Moreover, if a shopping list includes at least one shopping list entry that is associated with a product identifier, the shopping list may also be used to determine which retailer provides the best deal on certain items or the best overall deal on all of the items in the shopping list. In some embodiments, the shopping list may be used to schedule a regular delivery of products, such as groceries, through a delivery service. In some embodiments, a shopping list may be shared between several users and edited collaboratively. 
     Turning to  FIGS. 15 ,  16 A, and  16 B, methods of organizing, creating, and editing a shopping list are depicted in accordance with embodiments. Turning specifically to  FIG. 15  and returning to shopping screen  100 , a user may select a “shopping list” button  104  to advance to the shopping lists screen  330 . Included in the shopping lists screen  330  may be a list  332  of shopping lists that the user has created. Selecting a shopping list entry  334  may advance the user to the shopping list screen  338 . The shopping list screen  338  may include a shopping list  340  which includes product entries  342 . The product entries  342  may include an indication of the product name or product type as well as other useful information. For example, a product entry  342  may include an attainment indicator  344  that indicates whether the user has purchased the item or placed the item within a shopping cart, for example. The user may toggle the attainment indicator  344  by selecting it. In addition, the attainment indicator  344  may toggle automatically upon buying the item through purchasing features of the electronic device  10 . 
     The shopping list may be populated with various types of product entries, such as product-specific entries, type-specific entries, and generic entries, for example. A generic entry may be added to the shopping list by manually typing a generic name for a particular product and may serve as a reminder to purchase the item. However, because a product identifier is not specified, product information services may not be available for that product entry. 
     A product-specific entry may be added to the shopping list by scanning the product or manually entering a product identifier such as UPC code. By identifying a specific product, the user may use the product information services, such as the price comparison features, which will be described below. To differentiate between product-specific entries and generic entries, an entry type indicator  346  may be included in the product entries  342 . The entry type indicator  346  may, therefore, remind the user about whether product information services are available for that item. 
     A type-specific entry is a product entry that is associated with a product identifier, when, in fact, the user is not committed to buying the specific product identified, but rather only a product of the same type. For example, a user may scan a bottle of salad dressing to conveniently add it to the shopping list  340  when, in fact, the user may willing to buy a different brand if it is cheaper. The brand flexibility of the user may have a significant effect in the outcome of the price comparison features of the electronic device  10 , which will be explained further below. Therefore, the user may indicate this brand flexibility by identifying the scanned product as type-specific. Therefore, in some embodiments, the entry type indicator  346  may also serve to indicate whether the user desires to buy the specific product identified, or only products of the same type. In such embodiments, the user may toggle the entry type indicator  346  by selecting it after the scanned product has been entered into the shopping list. 
     Various features of the electronic device  10  may be available to the user from the shopping list screen  338 . For example, by selecting the “shop” button, the user may access the product information services of the electronic device  10 , which will be explained below. Additionally, the user may delete a shopping list  340  by selecting the “delete list” button  350  or edit a list by selecting the “edit list” button  352 . As shown in  FIG. 15 , the user may advance to the edit list screen in two ways. First, the user may select the “edit list” button  352  from the shopping list screen  339 , in which case, the user is advanced to the edit list screen  354 . Secondly, the user may select the “new list” button  336  from the shopping lists screen  330 , in which case, the user is advanced to the new list screen  355 , where the user is prompted to enter a name for the new shopping list by the user instruction message  164 . The new list screen  355  may also include the text entry box  198  and the keyboard interface  200  for entering the name of the new list. Selection of the “ok” button  356  then advances the user to the edit list screen  354 . 
     Turning to  FIG. 16A , a method for editing a new or existing shopping list by scanning items is shown. As described above, the user may advance to the edit list screen  354  by selecting the “edit list” button  352  while in the shopping list screen  338 . Within the edit list screen  354 , the user may add items to or delete items from the shopping list. The edit list screen  354  may include the shopping list  340  with product entries  342  shown substantially as they appear in the shopping list screen  338 . The user may delete product entries  342  from the shopping list  340  by selecting the “delete” button  358  positioned adjacent to the product entry  342 . 
     The edit list screen  354  may also include an add items window  360  which provides a variety of methods for adding product entries  342  to the shopping list  340 . For example, a user may wish to add a product entry  342  to the shopping list  340  by scanning the product in accordance with the methods described in  FIGS. 5-10  above. Accordingly, the user may advance to the scan item screen  150  by selecting the “scan” button  362 . The user may then utilize all the methods included in electronic device  10  for identifying a product. In the example shown in  FIG. 16 , the user selects the “touch scan” button  152 , advances to the touch scan screen  162  and scans the desired product. When the user is satisfied with the results of the scan, the user may select the “add” button  368 , which adds the scanned item to the shopping list  340  and returns the user back to the edit list screen  354 . 
     Turning to  FIG. 16B , methods of adding items to a shopping list by browsing through a list of recent scans or entering an item manually are shown. The user may browse recent scans by selecting the recent scans button  160  from the scan screen  150 . Additionally, to allow the user to access this feature with fewer button presses, the edit list screen  354  may also include a recent scans button  364 . The user may then select the “recent scans” button  364  and advance to the recent scans screen  204 , described above in relation to  FIG. 10 . When accessing the recent scans screen  204  from the edit list screen  354 , the recent scans entries  208  may include “add” buttons  370 , which allow the user to add the selected item to the shopping list. In some embodiments, selection of the “add” button  370  may also return the user back to the edit list screen  354 . 
     To add a product name to the shopping list  340  manually, the user may select the “manual entry” button  366  to advance to the manual entry screen  372 . The manual entry screen  372  may include user a instruction message  164 , a text entry box  198 , and keyboard interface  200  for typing the product type name. Selection of the “ok” button  374  adds the product name to the list and returns the user to the edit list screen  354 . As discussed above, when a product name is added manually, the product entry  342  may include an indicator, such as the entry type indicator  346  that indicates that the product information services of the device  10  may not be available for that product entry  342 . 
     Shopping lists may be saved in the storage memory  58  of the electronic device  10 . Additionally, some or all shopping lists accessible to the electronic device  10  may be stored remotely, such as on the Internet  91 . Furthermore, shopping lists stored on the Internet  91  may be shared between several users. A shared shopping list may be accessible on-line to a small group of users such as family members, room-mates, or co-workers allowing all of the users to edit the list. Because the shared list is stored on-line the shopping list may be edited through any web accessible device, such as the electronic device  10  or a personal computer. 
     Turning now to  FIGS. 17 through 20 , various product information services of the device  10  are shown in accordance with embodiments. Specifically, methods of bargain hunting for items in the shopping list are shown. The electronic device  10  may facilitate bargain hunting by allowing the user to search one or more retailers to obtain pricing information for each item in the shopping list. This information may then be presented to the user so that the user may make an informed decision regarding which retailer or retailers to visit to acquire the items on the list. Furthermore, embodiments may include any form of data presentation that helps a user to make an informed shopping decision. For example, the electronic device  10  may present the prices for individual products at a specific retailer, the total price for all of the products on the shopping list at a specific retailer, the travel distance to a retailer, the number of items that a retailer carries, special offers available through a retailer, the address or telephone number of a retailer, store hours, etc. 
     Turning specifically to  FIG. 17 , a method of initiating a retailer search is shown. Before a retailer search is conducted, the device may use information regarding the search parameters or the type of data presentation that the user desires. Therefore, selecting the “shop” button  348  in the shopping list screen  338  may advance the user to a shop list screen  378  that prompts the user to enter the information. For example, the user may be prompted to select one or more retailers from the retailer categories list  110 . As described above, in relation to  FIG. 5 , selection of one or more retailer categories  112  will identify the retailers that the user wishes to search. For another example, the shop list screen  378  may also include an indicator  380  by which the user may indicate the number of stops that the user is willing to make to obtain the items on the shopping list. The user may specify the desired number of stops by selecting the data entry elements  382 . To initiate the search of retailers, the user may select the “shop now” button  384 , which will advance the user to a screen that may vary according to the number of stops that the user indicated. 
     Turning now to  FIGS. 18 and 19 , methods of bargain hunting a shopping list wherein the user specifies one stop are shown. As shown in the shop list screen  378  of  FIG. 18 , the user has indicated a desire to make one stop, i.e. to visit one retailer, to obtain the items on the user&#39;s list. After selecting the “shop now” button  384 , the electronic device  10  may initiate an information request to the data manager  92 . 
     As part of the information request, the electronic device  10  may send a broad range of information to the data manager  92 , including product identifiers for all items in the shopping list, the current location of the user, a home location specified by the user, retailer preferences as selected in the retailer category list  110 , and a request ID that corresponds with the one-stop shopping feature of the electronic device  10 . Using some or all of this information, the data manager  92  may then compile an array of retailer information by searching the retailer database  96  for retailers that fit within the search criteria specified. The retailer information may include pricing information for each retailer and each item in the shopping list. 
     The pricing information obtained by the data manager  92  may vary depending on how the product was entered into the shopping list  340 . As stated above, the shopping list  340  may include a mix of product-specific entries, type-specific entries, and generic entries. For a product-specific entry, the data manager  92  obtains a product price that matches the identified product. However, for a type-specific entry, the data manager  92  may obtain the lowest price available for comparable items of the same type as the identified product. Additionally, if a price for a product entry  342  is unavailable, then a manufacturer recommended price may be substituted for an actual retail price in calculating the total price. In this way, the user will be able to make a meaningful price comparison between retailers that carry different items. For a generic entry, i.e. a shopping list entry that is not associated with a product identifier, pricing information may not be obtained. 
     In addition to obtaining pricing information, the data manager  92  may also derive secondary information, such as the total price for all of the items in the list at each retailer and/or the travel distance to the retailer, for example. The data manager may then send some or all of this information to the electronic device  10 . In some embodiments, the data manager  92  may send only information pertaining to a limited number of retailers. For example, the data manager  92  may select retailers based on proximity to the user, lowest total price, availability of the greatest number of items on the user&#39;s shopping list, or other useful criteria, such as user preferences. Furthermore, user preferences may be provided by the user, or the data manager  92  or device  10  may include software designed to “learn” user preferences based on past product queries or online purchases, for example. Based on of these criteria or combinations thereof, the data manager  92  may then send only the most relevant retailer information back to the electronic device  10 . 
     After the retailer information is received by the electronic device  10 , the user may be advanced to the one-stop shopping screen  386 . The one-stop shopping screen  386  may include a retailer list  388  with one or more retailer entries  390 . Each of the retailer entries  390  may include one or more information elements for presenting useful information about the retailer. For example, a retailer entry  390  may include a retailer indicator  392  listing the particular retailer to which the information applies. The retailer entry  390  may also include a distance indicator  394 , which may indicate a distance from the user&#39;s current geographical location to the geographical location of the retailer or a distance between the retailer and a home location specified by the user. The retailer entry  390  may also include an availability indicator  398 , which may serve to indicate the number of items in the shopping list that are available through the retailer. Moreover, the retailer entry  390  may include a total price indicator  396  that may indicate the total price of all the products included in the shopping list. 
     The user may also acquire additional details about the list by selecting a particular retailer entry  390  and selecting the “show list” button  402 , which will advance the user to the shopping list screen  404 . The shopping list screen  404  may include a modified shopping list  406  with list entries  408 . The modified shopping list  406  may provide different information compared to the original, user-specified shopping list  340  shown in the shopping list screen  338 . For example, the list entries  408  may provide product information that pertains to the particular retailer selected, such as the retailer&#39;s listed price for the item. For another example, some of the items in the original shopping list  340  may be substituted with different products of the same product type. This product substitution may occur when, as stated above, the user creates a type-specific entry by toggling the entry type indicator  346  to indicate a lack of brand preference. 
     In some embodiments, the shopping list screen  404  may serve as a gateway to other shopping related features of the electronic device  10 , which have been described hereinabove. For example, the shopping list screen  404  may include a “map” button  234 , which allows the user to access the mapping features of the electronic device  10 , as described in relation to  FIG. 12 . For another example, the shopping list screen  404  may also include a “view promotions” button  236  which allows the user to view special promotions from the retailer or download coupons, as also described in relation to  FIG. 12 . In addition, selection of a list entry  404  may advance the user to the scanned item screen  174 , which allows the user to acquire product information for the selected item, as described above in relation to  FIG. 11 . 
     In some embodiments, the shopping list screen  404  may allow a user to purchase all of the items in the shopping list remotely. For example, the shopping list screen  404  may provide an option for directing the user to an on-line shopping webpage of the retailer through a web application of the electronic device  10 , as shown in  FIG. 12 . Alternatively, the electronic device  10  may allow a user to send the shopping list to a delivery service, such as a grocery delivery service, for example. Additionally, the shopping list may pertain to consumable items that are to be replenished on a regular basis, such as food, household supplies, or office supplies, and the user may schedule regular deliveries of the items in the shopping list. The shopping list may be communicated to the delivery service and may include information regarding requested delivery dates. In some embodiments, the shopping list may be automatically communicated to the delivery service at a time interval specified by the user. 
     In some cases, after viewing the information available at the one-stop shopping screen  386 , the user may wish to visit more than one of the retailers in the retailer list  388 . Therefore, in some embodiments, the electronic device  10  may provide a tool for splitting the shopping list between two or more retailers and creating a multiple-stop shopping trip. In one embodiment, as shown in  FIG. 19 , the user may create a multiple-stop shopping trip by selecting two or more retailers from the retailer list  388  and then selecting the “create trip” button  400 . After the user selects the “create trip” button  400 , two or more partial shopping lists may be created by dividing the shopping list between the two or more retailers selected, according to which retailer offers the lowest price for each product in the shopping list, for example. The division of the shopping list may be carried out by the data manager  92 , or by the electronic device  10 . 
     After the division of the shopping list is accomplished, the user may be advanced to the shopping trip screen  410 . The shopping trip screen  410  may include a destination list  412  with destination entries  414  that correspond with the retailers selected by the user at the one-stop-shopping screen  386 . The order in which the retailers appear in the destination list  412  may be based on obtaining a short round trip distance between the retailers. The destination entries  414  may include a number of information elements, such as a distance indicator  394  that displays a distance between the retailer and the user of the electronic device  10  or between two retailers in the destination list  412 . The destination entries  414  may also include a total price indicator  396  that shows the total price of the items in the partial shopping list for that retailer. The destination entries  414  may also include an availability indicator  398  that shows the number of items included in the partial shopping list for that retailer. 
     Upon selecting a destination entry  414 , the user may advance to the destination screen  416 , which includes the partial shopping list  418 . As with the shopping list screen  338 , the partial shopping list  418  may include product entries  342  and the attainment indicator  344 . When visiting the retailer, the user may use the partial shopping list  418  as a reminder to purchase the items, and may select the attainment indicator  344  to mark certain items as having been obtained. If the user returns to the shopping list screen  338 , the attainment indicator information specified by the user at the destination screen  416  may carry back to the shopping list screen  338 . 
     At both the shopping trip screen  410  and the destination screen  416 , the user may select the “map” button  234  to engage the map features of the electronic device  10 , as described in  FIG. 12 . The information displayed on the map screen  240  may depend on which screen was active when the user selected the “map” button  234 . For example, if the user selects the “map” button  234  from the shopping trip screen  410 , the map element  246  may display each of the retailers included in the destination list  412 , including a trace following the preferred route between the retailers to minimize travel time and/or distance. Alternatively, If the user selects the “map” button  234  from the destination screen  416 , the map element  246  may show only the retailer displayed in the destination screen  416 . 
     In some cases, the user may want to create a multiple-stop shopping trip without specifying which retailers should be included in the shopping trip, thereby allowing the electronic device  10  or data manager  92  greater flexibility to obtain the lowest total price. Turning to  FIG. 20 , another method of creating a multiple-stop shopping trip is shown, in accordance with embodiments. As shown in  FIG. 20 , the user may, from the shop list screen  378 , input a number of stops greater than one before selecting the “shop now” button  384 . 
     In some embodiments, selection of the “shop now” button  384  with a number of stops greater than one causes the electronic device  10  to send an information request packet to the data manager  92  that includes the complete shopping list, the selected retailers, and the maximum number of stops. The data manager  92  may then create one or more suggested shopping trips by dividing the list among two or more of the selected retailers, with the number of retailers per shopping trip not to exceed the number of stops that the user specified. In some embodiments, the data manager  92  may create a shopping trip for every possible combination of retailers selected by the user at the shop list screen  378 . The data manager  92  may also calculate the total price for the items in the shopping list and the total distance that the user would travel in completing each suggested shopping trip. If the data manager creates a large number of shopping trips, the data manager may rank the shopping trips, according to total price, for example, and send only a certain number of higher ranked shopping trips back to the electronic device  10 . 
     After the data manager  92  sends the shopping trip information to the electronic device  10 , the electronic device  10  may then advance the user to the multi-stop shopping screen  420 . The multi-stop shopping screen  420  may include a suggested trips list  422  with trip entries  424  for some or all of the shopping trips created by the data manager  92 . The trip entries  424  may include various information elements that may be useful to the user. For example, the trip entries  424  may include a distance indicator  394  and/or a total price indicator  396 . Furthermore, the trip entries  424  may be organized according to a criteria specified by the user, such as lowest total price. Upon selecting a particular trip entry  424 , the user may advance to the shopping trip screen  410 , which was described above in relation to  FIG. 19 . The user may then select a destination entry  414  to advance to the destination screen  416 , which displays the partial shopping list  418 . 
     While many of the shopping features described herein are controlled by the user, other features of the electronic device  10  may allow a manufacturer, retailer, or other advertiser to send shopping related information to the electronic device  10  without a specific request by the user for the information. In some embodiments, the electronic device  10  may briefly interject an advertisement window, such as the promotion screen  252 , in response to a related selection of the user. For example, upon selection of the “buy now” button  238 , as shown in the retailer information screen  228 , the electronic device  10  may advance to promotions screen  252  or some other advertisement window before advancing to the online shopping screen  260 . For another example, an advertisement window may also appear upon the identification of a particular product at the scan item screen  150 . In various embodiments, the advertising window may appear at any time that a user makes a selection that identifies a particular product or retailer and may provide the advertiser an opportunity to attract the consumer&#39;s attention to its own related products or promotions. The advertisement window may include a message from the advertiser, which may be presented in the form of text, a picture, video, or audio. 
     Accordingly, the data manager  92  may store advertisement information within the manufacturer database  94  and/or the retailer database  96 . The information stored in these databases may include the full advertisement as shown in the advertisement window or the database may include a web address to an on-line webpage, in which case the data manager  92  may send the web address to the electronic device  10  and link the user to the web address through the web application of the electronic device  10 . 
     Embodiments are also directed to systems and methods wherein an individual store may create an enhanced in-store shopping experience for users of the electronic device  10 .  FIGS. 21-25  illustrate a system and methods for using an electronic device  10  to facilitate in-store shopping. In embodiments, the user may create a shopping list of store merchandise while browsing the store and may place an order and check out using the electronic device  10 , as described further below. 
     Turning specifically to  FIG. 21 , a store-wide data transfer system  426  is shown in accordance with embodiments. The store-wide data transfer system  426  may allow a user of the electronic device  10  to access the shopping features offered by the store. To gain access to the store-wide data transfer system  426  the electronic device  10  may first communicate with the NFC device  428 , which may be passive or active and may be controlled by a greeter, as shown in  FIG. 21 , or may be included in a customer information kiosk. In some embodiments, the NFC device  428  may be a model of an iPhone® available from Apple Inc. of Cupertino, Calif. 
     Using information acquired from the NFC device  428 , the electronic device  10  may connect to a server  430  through the LAN  89 . The server  430  may be coupled to one or more databases, including a store database  432 . The store database may hold product information regarding merchandise available in the store, such as brand name, model number, serial number, SKU number, UPC code, product descriptions, store prices, locations in the store where products are located, the number of items in stock, media files related to specific products, etc. The store database may also include other store specific information such as a map of the store. 
     The server  430  may also be coupled to a consumer data base  434  that holds consumer related information such as billing information, contact information, shipping addresses, purchase orders and records regarding previous purchases, etc. Furthermore, the server may also be coupled to a display  436  that allows a purchase order of a customer to be displayed so that a store employee may process the order. 
     Turning to  FIG. 22 , a system for allowing a user to create a shopping list with the electronic device  10  is shown. To facilitate the addition of items to a shopping list, each product  78  throughout the store may be associated with an NFC device  80 , such as an RFID tag. The NFC device  80  may be coupled directly to the product  78  or may be coupled to a product display element, such as a sign located in front of the product as shown in  FIG. 22 . The NFC communications between the electronic device  10  and the NFC device  80  may allow a user to acquire a product identifier related to the product  78 , as previously described in relation to  FIG. 4 . 
     Turning to  FIG. 23 , a method of providing in-store shopping through the store-wide data transfer system  426  is shown in accordance with embodiments. As shown in  FIG. 23 , the user may access on the in-store shopping features of the electronic device  10  by selecting the “in-store” shopping button  107  from the shopping screen  100 . Selection of the “in-store” shopping button  107  may turn on the NFC interface  50  of the electronic device  10  and advance the user to the message screen  438 . 
     The message screen  438  may include a series of progress indicators  440 . The first progress indicator  440  may instruct the user to touch the electronic device  10  to the store&#39;s NFC device  428 . As shown in  FIG. 21 , the NFC interface  50  may then send an output signal  82  to the NFC device  428 , requesting a connection to the store&#39;s LAN  89 . In response, the NFC device  428  may transmit a return signal  84 , which may carry networking information used to connect to the electronic device  10  to the store&#39;s LAN  89 , such as a service set identifier (SSID), channel, and encryption key. 
     After acquiring the networking information, the first progress indicator  440  may provide feedback, informing the user of the success of the NFC communication, and the electronic device  10  may connect to the server  430 . Once connected to the server  430 , the electronic device  10  may provide information used to identify the electronic device  10  and distinguish it from other electronic devices of other customers in the store. Furthermore, the server  430  may load specialized software that includes the shopping tools offered by the store, as described below. Because the electronic device  10  communicates with the server  430  wirelessly, the user may move about the store while the software is downloaded. Meanwhile, the message screen  438  may display a progress indicator  440  informing the user that software is being downloaded. 
     After downloading the software from the server  430 , the message screen  438  may provide appropriate feedback through the progress indicators  440  before advancing the user to the in-store shopping screen  442 . In some embodiments, the in-store shopping screen  442  may include a retailer picture  230  and a shopping list  340  with product entries  342 . After advancing to the in-store shopping screen  442 , the user is then ready to start adding items to the shopping list  340 . 
     When the user finds an item that he wishes to purchase, the user may select the “add item” button  444 . Selection of the “add item” button  444  may turn on the NFC interface  50  and advance the user to the touch scan screen  162 , which was described above in relation to  FIG. 6 . The user may then acquire a product identifier by touching the NFC interface  50  to the NFC device  80 . 
     After the successful scan of the selected item, the item may be added to the shopping list  340  and the user returned to the in-store shopping screen  442 . Scanning the item may also cause the electronic device  10  to initiate a request for product related information from the server. Such product related information may include a product description, product price, product picture, the number of products in stock, or any other information that may be obtained from the store database  432  for the product. 
     Turning now to  FIG. 24 , and returning to the in-store shopping screen  442 , methods of purchasing the items in the shopping list  340  are shown in accordance with embodiments. From the in-store shopping screen  442  the user may select the “checkout” button  446 , which may advance the user to the checkout screen  450 . The checkout screen may provide various options by which the user may purchase the items in the shopping list  340 . In some cases, the user may which to purchase items in the shopping list electronically. In that case, the user may select the “buy now” button  452 , which causes the items to be purchased electronically. 
     After selecting the “buy now” button  452  the user may be prompted to enter payment information such as credit card information, debit card information, prepaid card information, or electronic check information, for example. In other embodiments, the consumer database  434  may already contain the required billing information. In yet other embodiments, the payment information may be stored on the electronic device and accessible to the shopping application, enabling a one-click checkout functionality. As such, the shopping application may display a list of payment options corresponding with payment information previously entered by the user into the electronic device  10 . The payment information may be managed by a shared application that enables one-click checkout functionality regardless of the particular retailer. Methods of conducting an electronic purchasing transaction are described in the commonly assigned patent application titled, “Portable Point of Purchase Devices and Methods,” by Gloria Lin et al., filed on Sep. 30, 2008, application Ser. No. 12/286,445 which is hereby incorporated by reference for all purposes. 
     In some cases, the user may wish to proceed to a cashier to checkout in person, which may be useful if the user wishes to pay in cash, for example. In that case, the user may select the “cashier checkout” button  454 , in which case the user may be prompted to proceed to a checkout station. 
     Upon selection of the “cashier checkout” button  454  or the “buy now button”  452 , the electronic device  10  may send a purchase request to the server  430 . The purchase request may include product identifiers for each of the products in the shopping list  340 . The server  430  may then create a purchase order and may send a list of the purchased items to the display  436 . A store employee may then retrieve the products from stock and deliver the products to a pickup area. 
     Meanwhile, if the user selected the “buy now” button  452 , the user may be advanced to the buy now screen  456 , which may inform the user that the user&#39;s order is being processed and that the user will be notified when the order is ready for pickup. If the user selected the “cashier checkout” button, however, the user may be advanced to the “in-store checkout” screen  458 , which instructs the user to proceed to a checkout station while the order is being processed. 
     When the order is ready for pickup, the server  430  may send a message to the electronic device  10 . In response to the incoming message the user may be advanced to an in-coming message screen  460 . In some embodiments, the in-coming message screen  460  may be a part of the text messaging application of the electronic device  10 , in which case the message may be delivered through SMS text messaging. In other embodiments, the in-coming message screen  460  may be generated by the in-store shopping software. The in-coming message screen  460  may include a message informing the user that the user&#39;s order is ready for pickup. 
     Turning now to  FIG. 25  and returning to the in-store shopping screen  438 , another feature of the in-store shopping application is shown in accordance with an embodiment. As shown in  FIG. 25 , various store related information may be accessible to the user from the in-store shopping screen  438 . For example, in one embodiment, the in-store shopping screen may include a “store map” button, selection of which advances the user to a store map screen  462  that includes a store map  464 . The store map may show the location of various items within the store. Additionally, the store map may be searchable. As such, the user may enter a product name into the text box  466  and the store map may identify the store location for the product with the location icon  468 .
