Title: Offline access of a network based application

Description:
INCORPORATION BY REFERENCE TO ANY PRIORITY APPLICATIONS 
     Any and all applications for which a foreign or domestic priority claim is made are identified in the Application Data Sheet as filed with the present application and are incorporated by reference under 37 CFR 1.57 and made a part of this specification. 
     BACKGROUND 
     Generally described, computing devices, such as mobile devices, can provide users with various functionality or functions through the execution of applications. In one aspect, a computing device, often referred to as a client computing device, can execute software code, referred to as a software application, that has been configured specifically for the operating system or operating environment associated with the client device. Based on their dependence to the operating system, such custom applications can be referred to as native application. In another aspect, network-based applications, also referred to as web apps or web applications, are hosted by browser software applications are used ubiquitously by users on communication networks, such as the Internet. Common web applications include electronic mail, online retail sales, online auctions, wikis and many other functions that are available for use over a network. 
     Unlike native applications, web applications allows for the development of an application that can be independent of a type of computer or operating system that is hosting the browser software application. Web applications commonly use a combination of server-side script (such as active server pages (ASP), PHP, etc.) and client-side script (such as hypertext markup language (HTML), JavaScript, etc.) to implement the web application. The client-side script can determine the presentation of information on the browser while the server-side script can be configured to store and retrieve information from a server. 
     Because web applications are hosted by a browser on a client computing device independent of operating environment, a user can use any computing device and or operating system that has a browser capable of executing on the client device. Web applications are popular due to the ubiquity of browsers, and the convenience of using a browser as a client. The ability to update and maintain web application without distributing and installing software on potentially thousands of client computers is an important reason for their popularity, as is the inherent support for cross-platform compatibility. 
     In a typical web application, a user is required to be in active communication with a network in order to access the content and functionality associated with the web application. This can lead to difficulties if a user needs to use the web application in an area has little or no network connectivity.

     DETAILED DESCRIPTION 
     Generally described, the present disclosure relates to an interactive computing system configured to provide a network-based application that can provide offline functionality. A user computing device can access the network-based application through the interactive computing system. The network-based application can be used by the user device to provide transaction information to a point-of-sale terminal in order to conduct a transaction when the network-based application is not in communication with the interactive computing system. For example, the network-based application can facilitate point-of-sale transactions even in scenarios when the user computing device does not have network connectivity or limited connectivity. 
     Illustratively, the network-based application can use an account-based system for accessing the content and functionality associated with the network-based application. The network-based application can define an online feature set and an offline feature set. The online feature set includes features available to a user when the user device is in communication with the interactive computing system and the offline feature set includes features available to the user when the user device is not in communication with the interactive computing system. The offline feature set can be accessed and utilized by the network-based application based on user account information, also referred to as user information, and application information stored in an application cache without requiring communication with the interactive computing system. 
     When in an offline mode, the network-based application can be configured to perform functions based on user account information. For example, the network-based application can provide a point-of-sale terminal with information sufficient to authorize a transaction. The information can include a computer readable code that is provided to the point-of-sale terminal. The computer readable code can include the user information embedded within the code. The point-of-sale terminal can communicate with the interactive computing system to authorize the transaction. Even though the network-based application is not in communication with interactive computing system, the network-based application can provide a user with the ability to provide sufficient information at the point-of-sale terminal to execute the transaction. 
     Illustratively, in some embodiment, the network-based application can be associated with a retail establishment, such as a food services provider. The network-based application can provide a user with functionality for managing one or more user accounts associated with the food service establishment, often provided as an account card having a bar code that can be read by a point-of-sale terminal. The user account cards can be associated with a specific user account. The cards can be loyalty cards, such as cards that accumulate points based on purchases made by the user, account cards, such as gift cards or charge cards that have a monetary account value for purchasing goods or services from the food service establishment, or other types of cards associated with the user account. In accordance with some embodiments, the network-based application can manage information associated with each card, such as updating card information, determining account balances, increasing account balances, associating additional cards with the user account, and providing other functionality for managing cards associated with the user account. The network-based application can be configured to provide a computer readable code embedded with user account information of an account card, such as a card identifier, an account identifier, an account balance, a non-monetary balance, and/or other user account information. Each account card can be associated with a different computer readable code. The computer readable code can be used to authorize payment of a transaction at the food service establishment. 
     In some embodiments, the network-based application can be configured to perform other functions associated with a food service establishment, such as viewing a menu or identifying a food service establishment closest to the user, generating orders that can be provided to the establishment. In some embodiments, the network-based application can be configured create a custom order that can be used to generate computer readable code associated with that order. A user can then provide the order to the food service establishment by presenting the machine readable code to a point-of-sale terminal. In some embodiments, the machine readable code for the order can be combined with the machine readable code for the payment information. 
     Although aspects of the present disclosure will be described with regard to an illustrative network-based application with offline functionality, one skilled in the relevant art will appreciate that the disclosed embodiments are illustrative in nature and should not be construed as limiting. Still further, although a number of illustrative examples will be discussed with regard to the present disclosure, such examples should not necessarily be construed as limiting. 
       FIG. 1  illustrates a network environment  100  for an interactive computing system that is configured to provide a network-based application with offline functionality. The networking environment  100  includes one or more user devices  104 , an interactive computing system  110  and one or more point-of-sale terminals  120  in communication with a network  102 . The user device  104  includes a browser  106  with an application cache  108 . The interactive computing system  110  includes an application module  112 , a user account module  114 , an application data store  116  and a user data store  118 . 
     The user device  104  can be representative of a plurality of user devices  104  that can communicate with an interactive computing system  110  through a network  102 . The user computing devices  104  can correspond to a wide variety of devices or components that are capable of initiating, receiving or facilitating communications over the communication network  102  including, but not limited to, personal computing devices, electronic book readers (e.g., e-book readers), hand held computing devices, integrated components for inclusion in computing devices, home electronics, appliances, vehicles, machinery, landline telephones, network-based telephones (e.g., voice over IP (“VoIP”), cordless telephones, cellular telephones, smart phones, modems, personal digital assistants, laptop computers, gaming devices, media devices, and the like. In an illustrative embodiment, the user computing devices  104  include a wide variety of software and hardware components for establishing communications over one or more communication networks, including wireless communication network, a wired communication network, or an IP-based telecommunication network. Illustrative components of a user computing device  104  will be described in greater detail with regard to  FIG. 2 . 
     The communication network  102  may be any wired network, wireless network or combination thereof. In addition, the communication network  102  may be a personal area network, local area network, wide area network, cable network, satellite network, cellular telephone network or combination thereof. Protocols and components for communicating via the Internet or any of the other aforementioned types of communication networks are well known to those skilled in the art of computer communications and thus, need not be described in more detail herein. 
     The point of sale terminal  120  can be in communication with the interactive computing system  110  over the network  102 . Additionally, the point of sale terminal  120  can communicate directly with the user devices  104 , such as via short range radio, direct wired connection, optical connections, and the like. The point-of-sale terminal  120  can be a terminal at a retail establishment, food service establishment, stand-alone kiosk, mobile device or other type of point-of-sale terminal. The point-of-sale terminal  120  can configured to have a scanning device or other mechanism capable of reading computer readable codes, such as bar codes, QR codes, or other visible computer readable codes. 
     Illustratively, the point-of-sale terminal  120  can have software and hardware configured to wirelessly communicate using radio frequency (RF), Bluetooth®, or other type of wireless communication protocol. The point-of-sale terminal  120  can be configured to receive a computer readable code from the user device  104  as part of a transaction and communicate information contained in the computer readable code to the interactive computing system  110  over the network. The interactive computing system  110  can authorize the information received from the point-of-sale terminal  120  in order to authorize the transaction. The point-of-sale terminal  120  can be configured to transmit information to the user device that can be used to update the network-based application based on the information received from the interactive computing system. In some embodiments, the point-of-sale terminal  120  can be associated with the same entity as the interactive computing system  110 . For example, the interactive computing system  110  and point-of-sale terminal  120  can be associated with a specific food service establishment. 
     The interactive computing system  110  includes an application module  112 , a user account module  114 , an application data store  116  and a user data store  118 . The interactive computing system  110  may be implemented in hardware and/or software and may, for instance, include one or more servers having physical computer hardware configured to implement computer executable instructions for performing various features that will be described herein. The one or more servers may be geographically disbursed or geographically co-located, for instance, in one or more data centers. 
     The interactive computing system  110  can include servers, which can communicate with the user devices  104  over the network  102  and which can provide access to various services of the interactive computing system  110 . The services of the interactive computing system  110  can be implemented by the content module  112  in conjunction with the authentication module  114 . These services can be implemented in physical computer hardware on the servers or in separate computing devices. Moreover, the processing of the various components or services of the interactive computing system  110  can be distributed across multiple machines, networks, or other computing resources. The various components or services of the interactive computing system  110  can also be implemented in one or more virtual machines or hosted computing environment (e.g., “cloud”) resources, rather than in dedicated servers. Likewise, the data repositories shown can represent local and/or remote, physical and/or logical data storage, including, for example, storage area networks or other distributed storage systems. Executable code modules that implement various functionalities of the interactive computing system  110  can be stored in the content data store  116  and user data store  118  on memories of the servers and/or on other types of non-transitory computer-readable storage media. The interactive computing system  110  can be configured so that each of the components shown can communicate with any other components. 
     The application module  112  can be configured to implement a network-based application on the user device. The application module  112  defines the features, content and functionality of the network-based application. The application module  112  can include executable code modules, for implementing the various functionalities of the network-based application, including server-side code modules configured to be implemented by the interactive computing system  110  and client-side code modules configured to be implemented by the user device  104 . The application module  112  can define the user interface and display parameters of the network-based application. 
     The network-based application can utilize an account-based system for controlling access to the features and functionality associated with the network-based application, such as an email account. The network-based application can store user information and general application information in an application cache on the user device. The application module  112  can be configured to define an online feature set and an offline feature set. The online feature set includes the content and functionality that are available to a user when the user device is in communication with the interactive computing system. The offline feature set includes the content and functionality of the network-based application that are available to the user when the user device is not in communication with the interactive computing system. The offline feature set can be a subset of the online feature set. 
     The offline feature set can be accessed and utilized by the network-based application based on the user information and application information stored in the application cache without requiring a connection to the interactive computing system. The application cache can be configured to store functionality and content associated with the network-based application. In addition to the functionality and content associated with the web application the application cache can also store user account information associated with the application. In some embodiments, the application cache can store user account information for a plurality of user accounts. The interactive computing system can flag information that requires an update. The updated information can be received by the user device and stored in the user device application cache. 
     In an illustrative example of offline functionality, a network-based application associated with a food service establishment can enable a user to prepare a custom order and provide payment to the food service establishment based on the user account information and application information stored in the application cache. 
     The application module  112  is in communication with the application data store  116 . The application data store  116  can include any content or data associated with the operation and functionality of the network-based application. The application data store  116  can represent local and/or remote, physical and/or logical data storage, including, for example, storage area networks or other distributed storage systems. 
     The user account module  114  can be configured to perform actions associated with information contained within user accounts. For example the user account module can be configured to authenticate authentication credentials provided by the application and interact with the point-of-sale terminal  120  in order to authorize transactions associated with information stored within a user account. The user account module can also be configured to update the user account when information is received that modifies the information stored in the user data store  118 . 
     The user data store  118  can store the user information associated with each user account of the interactive computing system. The user account information can include user preferences, personal information, financial information, and other account specific information. The financial information can include information such as credit card information, store card balances, or other financial information associated with the user account, such as recurring subscriptions. 
       FIG. 2  illustrates components of an embodiment of a user computing device  104 , such as a mobile telephone. The user computing device  104  may include one or more processing units  202 , such as one or more CPUs. The user computing device  104  may also include system memory  204 , which may correspond to any combination of volatile and/or non-volatile computer-readable storage media. The system memory  204  may store information which provides an operating system module  206 , various program modules  208 , program data  210 , and other modules. The user device  104  can have browser software installed in system memory  204 , program modules  208  and/or program data  210 . 
     The browser software can be configured to have an application cache. The application cache can be configured to store the information received from the interactive computing system for the network-based application. When the browser interacts with the web application the browser can receive information associated with the application and store the information in the application cache. The information stored in the application cache can include application information and user account information. 
     In either an online mode or an offline mode, the network-based application can be retrieved from application cache before communicating with the interactive computing system. By loading the application from the application cache first, the network-based application can decrease load times, reduce bandwidth requirements usage of the application and increase performance. 
     The user computing device  104  performs functions by using the processing unit(s)  202  to execute modules stored in the system memory  204 . The user computing device  104  may also include one or more input devices  212  (keyboard, mouse device, specialized selection keys, etc.) and one or more output devices  214  (displays, printers, audio output mechanisms, etc.). One skilled in the relevant art will appreciate that additional or alternative software modules and/or hardware components may also be included in the user computing device  104  to carry out other intended functions such as mobile telephone functions. 
     With continued reference to  FIG. 2 , the user computing device  104  may also include a battery  222 , one or more types of removable storage  216  and one or more types of non-removable storage  218 . In some embodiments the device can be connected to an external power source, such as an AC power outlet. Still further, the user computing device  104  can include communication components  220 , such as a cellular transceiver and a wireless transceiver, for facilitating communication via wired and wireless communication networks. These transceivers facilitate such communication using various communication protocols including, but not limited to, Bluetooth, the family of IEEE 802.11 technical standards (“WiFi”), the IEEE 802.16 standards (“WiMax), short message service (“SMS”), voice over IP (“VoIP”) as well as various generation cellular air interface protocols (including, but not limited to, air interface protocols based on code division multiplex access (CDMA), time division multiple access (TDMA), global system for mobile communications (GSM), wireband code division multiplex access (WCDMA), code division multiplex access 3 rd  generation (CDMA1040), time division synchronous code division multiple access (TD-SCDMA), wavelength and time division multiple access (WTDMA), long term evolution (LTE), orthogonal frequency division multiple access (OFDMA), and similar technologies). 
     The above-enumerated list of components is representative and is not exhaustive of the types of functions performed, or components implemented, by the user computing device  104 . One skilled in the relevant art will appreciate that additional or alternative components may also be included in the user computing device  104  to carry out other intended functions. 
       FIGS. 3A and 3B  illustrate state diagrams showing interactions between a point of sale terminal  120 , a browser  106 , an application cache  108  and an interactive computing system  110 .  FIG. 3A  illustrates when the network-based application is operating in an online mode and is in communication with the interactive computing system.  FIG. 3B  illustrates when the network-based application is operating in an offline mode and is not in communication with the interactive computing system  110 . 
     At (1), the network-based application requests information from the interactive computing system. The request can be made when the user device accesses the network-based application through a browser. The request may include requests for all of the information associated with the network-based application, a portion of the information associated with the network-based application and/or updates to the information stored in the application cache. The network-based application can request information that is designated as not being stored in the application cache. 
     At (2), the interactive computing system processes the request from the network-based application. The request can identify application information and user account information. The request may be an authentication request. For an authentication request, the request may include authentication credentials for a user account that can be authenticated by the user account module. The authentication credentials can include an account identifier and password associated with a user account stored on the interactive computing system. If the authentication is successful, the interactive computing system can provide access to the application. 
     At (3), the interactive computing system provides application information and/or user account information to the device. At (4) the browser stores the application information and/or the user information in the application cache. The application information can include information that applies to all users that utilize the network-based application. For example, a network-based application has information that every user of application receives, such as user interface, formatting, and other application information. The user information can be information associated with a specific user account and can be stored in a user data store on the interactive computing system. The actions associated with (1) through (4) can be completed as necessary until the application can be implemented within the browser. 
     At (5), the user can interact with the network-based application and utilize the content and functionality provided in the network-based application in the online feature set. For example, the user can update user account information stored on the interactive computing system. Updates to the user account information on the network-based application can be communicated back to the interactive computing system. As the information is communicated between the interactive computing system and the browser, the information in the application cache can be continually updated so that the user device is up-to-date with the most recent information. The updated information can be used when the network-based application is operated in the offline mode. 
       FIG. 3B  illustrates an offline mode of operation for the network-based application. At (1), the browser  106  requests and loads the network-based application from the application cache  108 . In some embodiments, the user may need to provide authentication credentials to access the network-based application. At (2), the application cache  108  provides the network-based application to the browser  106 . If authentication is needed, the network-based application can use the information in the application cache to authenticate the user and access the correct user account. 
     At (3), the user device can interact with the network-based application. The network-based application may have an offline feature set that provides at least a portion of the functionality of the online feature set. In the offline mode, the network-based application is not be able to update information in the application with information from the interactive computing system. In offline mode the network-based application can provide access to user account information. In some embodiments, the network-based application may default to the last user account accessed in online mode or it may provide an authentication interface that the user logs into in order to access the user account. Authentication of the user account may be implemented in accordance with information stored in the application cache. In some embodiments, the network-based application may use a web object, such as a cookie, for storing information that the network-based application can use to authenticate and connect the user to a user account. When the user is connected to the user account, the user can access functions and information that utilize user account information. The offline feature set can contain limited functionality for updating user account information such as financial information, adding funds to an account, or other functionality that requires a network connection. 
     The offline mode feature set can include functionality that allows a user to interact with user account information, such as financial information. For example, the network-based application can use the user account information stored in the application cached to authorize the payment of a transaction at a point-of-sale terminal. In some embodiments, the network-based application can generate a computer readable code that can communicate user information to the point-of-sale terminal, which can be used by the point-of-sale terminal to authorize a transaction. 
     In some embodiments, an account can have one or more virtual and/or physical cards associated with the user account. The cards can be loyalty cards, such as cards that accumulate points based on purchases made by the user, account cards, such as gift cards or charge cards that have a monetary account value for purchasing goods or services, or other types of cards associated with the user account. Each card can include a card identifier associated with the card, such as a card number or account number. In some embodiments, the card can include an account balance. 
     The user information can be used by the network-based application to provide the point-of-sale terminal with transaction information to authorize a transaction. The point-of-sale terminal can use the card identifier to authorize the transaction based on information stored in the user data store on the interactive computing system. The network-based application can provide transaction information to the point-of-sale terminal. In some embodiments, the transaction information includes computer readable code. The computer readable code can be generated by the network-based application. In some embodiments, the computer readable code can be generated by the interactive computing system and stored in application cache. The computer readable code can include the user information embedded within the code. The computer readable code can be a bar code, QR code, radio frequency (RF) identification code, or other type of computer generated code. The computer generated code can be a visible code or a code that is transmitted to the point-of-sale using near field communication technologies such as RF, Bluetooth® or other technologies for communicating wirelessly over a relatively short distance. In some embodiments, the computer readable code can include a card identifier and a custom order. For example, the network-based application could generate a custom order for the user and combine the custom order information with and the card information. 
     At (4), transaction information, such as a computer generated code, can be provided to the point-of-sale terminal for a transaction. The transaction information can include instructions, a computer readable code, or other type of information that the user can present to the point-of-sale terminal. The transaction information includes at least a portion of the user account information stored in the application cache. For example the network-based application can generate a computer generated code that has user account information embedded in the computer generated code. In some embodiments, the user account information includes a card identifier, an account balance associated with identified card, a user account identifier, a non-monetary account balance, and/or other information that can be used to by the point-of-sale terminal for processing the transaction. The transaction information can be provided in order to authorize payment of the transaction. 
     At (5), the point-of-sale terminal processes the transaction information provided by the network-based application and transmits an authorization request to the interactive computing system based, at least in part, on the transaction information. The point-of-sale terminal can transmit the transaction information to the interactive computing system for authentication. In some embodiments, the network-based application may provide sufficient information such that the point-of-sale terminal can authorize the transaction without requesting authorization from the interactive computing system. For example, the transaction information may include a card identifier and an account balance. 
     At (6), the interactive computing system processes the authorization request based on the transaction information provided by the point-of-sale terminal. In an exemplary embodiment, the user account module of the interactive computing system can determine whether to authorize or deny the transaction request. The transaction information is used to identify a user account stored in the user data store. The user account module can approve or deny the authorization request based on the user account information. For example, the user account module can determine whether there are sufficient or insufficient funds for the proposed transaction. 
     At (7), the interactive computing system sends the response back to the point-of-sale terminal, approving or denying the transaction. The interactive computing system can also update the user account information based on the result of the transaction. The next time the browser accesses the network-based application on the interactive computing system can provide updated user information to the browser for storage in the application cache. 
       FIG. 4A  illustrates a user interface  410  of a network-based application having a plurality of user inputs for a user to provide authentication credentials for accessing the network-based application. The login user interface  410  includes a plurality of authorization inputs, including a username input  412  and a password input  414 . When the user selects the login user input  416 , the authentication credentials provided by the user to inputs  412  and  414  can be provided to the interactive computing system  110  for authentication. After the user device completes the authentication, the user device can be logged into the network-based application under the user account associated with the authentication credentials. In some embodiments, the login user interface can be accessed in the offline mode and the online mode of the network-based application. 
       FIG. 4B  illustrates a user interface  420  for displaying content provided by the network-based application. The user interface  420  displays content user controls, including an order control  422 , a drinks control  424 , a food control  426 , a payment control  428 , and a user preferences control  430 . Each of these controls can be assigned specific functions in accordance with the functionality assigned by the application module  112 . When in an online mode the user can have access to the features of the network-based application defined by the online feature set. When in the offline mode the user can access a subset of features provided by the network-based application as defined by the offline feature set. Only features associated with the offline feature set can accessed when the user is in the offline mode. In some embodiments, visual characteristics of controls that are not associated with the offline feature set can be modified, for example, a control can be dimmed or greyed out to illustrate that the control or object is not functioning. In some embodiments, objects that would require a network connection to function can fall back on the most recent information received from the interactive computing system. In such a case, the information may not be the most current information that would be available from the interactive computing system. 
       FIGS. 5A and 5B  illustrate an embodiment of a network-based application that can implement general functions that use application information stored in the application cache. In this embodiment, the user can generate, reproduce or recall a computer readable code that represents a custom food order.  FIG. 5A  illustrates a user interface  340  showing an order  512  created by the user. The order interface  510  illustrates content that is available to user in the offline feature set. The order  512  includes a plurality of items selected by the user, a cost associated with the items and an order total. In this illustrative example, the user can access a menu, create one or more orders, add or remove items from the proposed order, and generate a custom order code. After the user creates the order, the user can generate the custom order by selecting the control  514 . 
       FIG. 5B  illustrates an interface  520  showing an embodiment of the generated custom order. The generated order can be represented by a machine readable code  522 . The machine readable code containing the order items of the custom order could be presented at a point-of-sale terminal for transmission of the order to a food service establishment for preparation. In some embodiments the use can choose to save the order to their user account with the control  524 .  FIGS. 5A and 5B  merely illustrate one exemplary embodiment of functionality that could be associated with a network-based application that could be performed while the network-based application is operating in an offline mode. The network-based application can have different permutations or functionality dependent upon the design of the web application. Additionally, in some embodiments, at least some portion of the machine readable codes may be pre-generated and stored by the user devices. In such embodiments, the user device may recall at least portions of the machine readable code in response to the generation of order. 
       FIGS. 6A through 6C  illustrate network-based application functionality that utilizes user information that is associated with a specific user account, whereas  FIGS. 5A and 5B  illustrate general functionality associated with application information.  FIGS. 6A through 6C  shows functionality associated with providing a virtual card, also referred to as an account card, for usage at an establishment associated with the virtual card.  FIG. 6A  illustrates a user interface  610  has various options including the card balance  612 , order information  614 ; payment information  616  and a card reload function  618 . The card balance  612  shows the balance of the card selected as the current method of payment. The card reload function  618  would not be available in the offline mode because it would require network connectivity in order to add funds to a card. 
       FIG. 6B  illustrates a payment information user interface  620 . In this embodiment the user interface  620  shows a virtual card  622 . The virtual card  622  can include identification information such as user name associated with the card  624 , a card nickname  626 , and a card identifier or account number  628 . The interface  620  can also continue to display the card balance  612  of the currently selected virtual card. In some embodiments where the user account has a plurality of virtual cards associated with the account, the network-based application may provide the user with an interface for selecting the virtual to use as the payment card. In such a case the card balance can be updated to show the balance of the card selected for payment. 
       FIG. 6C  illustrates an embodiment of additional information associated with the virtual card selected for payment. In the illustrated embodiment, the backside  632  of the card is illustrated. In one embodiment the user could select the virtual card  622  to transition to the backside  632 . In some embodiments, the user can use a touch based-control, such as tapping the card  622  in order to cause the card to flip over to reveal the backside  632  and show the computer readable code  634 . The computer readable code  634  includes transaction information that a point-of-sale terminal can use approve or deny a transaction. 
     In some embodiments the computer readable code  634  can provide transaction information that the point-of-sale terminal can use to communicate with the interactive computing system in order to approve a transaction. For example, the computer readable code  634  can provide a card identifier, a user account identifier, an account balance, and/or other information. In some embodiments, the computer readable code  634  can provide information to the point-of-sale terminal that can be used by the point-of-sale terminal to approve the transaction, such as a card account number and an account balance. Based on this information the point of sale terminal could authorize the transaction. When the point of sale terminal authorizes the transaction, the network based application may not automatically update, but the point of sale terminal can transfer the information to the interactive computing system. The interactive computing system can use that information to update the user account information associated with the virtual card. When the network-based application goes back to online mode, the network-based application receives an update to the user account information based on that transaction with the point of sale terminal. 
       FIG. 7  illustrates a flowchart of an embodiment of a routine  700  for offline usage of user account data. The routine  700  can be implemented by a browser  106  executing a network-based application. At block  702  a network-based application is loaded into a browser on a user device from an application cache of the browser. The network-based application is loaded based on information previously provided by an interactive computing system. The information stored in the application cached includes application information and user information. 
     At block  704  the network-based application authorizes access to a user account. Access to the user account can be granted based on authentication credentials provided by a user of the network-based application. In some embodiments, access to the user account can be granted based on a content object, such as a cookie, that can provide the appropriate authentication credentials to access the user account. 
     At block  706 , the network-based application can receive input to access functions associated with an offline feature set. The network-based application can be configured to implement functions associated with application information and user information based on the input received from a user. The network-based application has access to the application information and user information stored in the application cache. The offline feature set can be a subset of the functions and content associated with the online feature set. The network-based application can access user information in order to perform functions that are associated with a specific user account. The user information stored in the application cache can provide the network-based application with sufficient information to implement specific functions related to the financial accounts associated with the user account. 
     At block  708 , the network-based application can provide a computer readable code associated with the user account that is configured to interact with a point-of-sale terminal. In some embodiments, the network-based application is configured to generate the computer readable code based on the information stored in the application cache. In some embodiments, the computer readable code is generated by the interactive computing system and provided to the network-based application, which is stored in the application cache. The computer readable code can provide a point-of-sale terminal with sufficient information to approve or deny a transaction associated with the computer readable code. The point-of-sale terminal can communicate with the interactive computing system to approve or deny the transaction based on the information provided by the network-based application. At block  710  the process ends.
