CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application is a non-provisional of and claims the benefit of the filing date of U.S. Provisional Patent Application No. 61/521,233, filed on Aug. 8, 2011, which is herein incorporated by reference in its entirety for all purposes. 
     
    
     BACKGROUND 
       [0002]    For businesses and merchants to improve their goods and services provided to consumers, merchants may gather additional data, such as sensitive or personal data (e.g. geographical location, profile information of the user, transaction history, or any other data from the user etc.) relating to the consumer as well as feedback data about the consumer&#39;s experience at a merchant, and analyze the data for future use. Consumers may be asked to fill out surveys or answer questions at a later time, and may be provided incentives for filling out a survey to provide additional feedback. However, such methods risk the additional data falling in to the wrong hands and being used for fraudulent or otherwise undesirable purposes. In addition, the filling out of surveys is often too time consuming and troublesome for consumers. 
         [0003]    Furthermore, when a consumer provides additional data of their experience at the merchant at a later time, the consumer may have forgotten relevant details of the experience. Also, the merchant may not be able to identify a transaction associated with the experience of the consumer, making it difficult for the merchant to target areas of improvement. 
         [0004]    Also, since the additional data is collected by the merchant or the merchant&#39;s employee in some cases, the merchant or its employee has access to the additional data. There may be some potential for the merchant or its employee to distribute the additional data and/or to tamper with and falsify the additional data. 
         [0005]    Embodiments of the invention address these and other problems, individually and collectively.

     DETAILED DESCRIPTION 
       [0025]    Many merchants or businesses providing products or services may like to collate customer information and receive customer feedback to improve products or services to increase business and revenue. Currently there are means for users to review and rate businesses and merchants, for example, through websites to share their experiences with other users. These review forums allow users to research merchants and businesses to help them determine which merchants to patronize based on other users&#39; reviews and ratings. However, these forums may not be as beneficial for merchants, because it is difficult for the merchant to associate a specific review with a specific transaction and/or user. Thus, the merchant may not be able to find an effective strategy to improve their business because they cannot target areas of improvement if they cannot associate a specific negative review or rating with a specific transaction. Additionally, since anyone can sign up for a review account on existing review websites, a merchant may create false reviews to alter their rating, affecting users&#39; trust in using rating services and motivation to rate merchants. Embodiments of the invention address this and other problems. 
         [0026]    Embodiments of the invention provide a system and method where additional data (e.g., information relating to a user, user feedback, ratings of the merchant by the user, etc.) may be associated with a specific transaction may be received at the time of the transaction, encrypted, transmitted by a portable consumer device such as a mobile phone or a payment card, to an access device, such as a point-of-sale terminal (POS terminal). The encrypted additional data can be transmitted to a server computer operated by a payment processing network (e.g., VisaNet) or entity other than the merchant. The server computer in the payment processing network may decrypt the encrypted additional data, and store the additional data in a database. At some point in time, the server computer can re-transmit the decrypted additional data to the merchant. 
         [0027]    Since the additional data is encrypted before being transmitted to the access device (e.g., POS terminal) and is only decrypted at the payment processing network (or entity other than the merchant), illegal distribution, merchant tampering and/or falsifying of the additional data can be prevented. For example, using embodiments of the invention, the merchant cannot falsify ratings data (e.g., change an unfavorable review into a favorable one) in an attempt to generate additional business. Additionally, since the additional data is collected at the same time a specific transaction is being conducted, the additional data (e.g., feedback, profile information of the user, etc.) can be directly associated with the specific transaction. This can tie a specific transaction to the additional data, thereby providing the merchant or other party with better analytics. For example, a specific review may be tied to a specific purchase, and a specific payment account number. If, for example, negative reviews are all provided by consumers within a specific time window associated with those purchases, this may indicate that poor customer service may have been provided during this time. 
         [0028]    In embodiments of the invention, payment transactions may be conducted using a portable consumer device that is used by a user. The portable consumer device may be a mobile communication device (e.g., handset, mobile phone, PDA) that has a specific application, or may be a payment card with an integrated chip (e.g., smartcard). 
         [0029]    Also in embodiments of the invention, the portable consumer device may interact with an access device. The access device may be a mobile POS terminal that the merchant may present to the user at the time of the transaction. As will be described below, the user may enter the additional data into the access device and the access device may generate and transmit an authorization request message comprising the encrypted additional data to a payment processing network. 
         [0030]    Embodiments of the invention using a mobile payment application on a portable consumer device, such as a mobile communication device or a card, may include an integrated chip used for cryptographic operations for payment security purposes. This integrated chip may be used in payment applications to conduct transactions to secure payment, as well as to collect, encrypt, store, and retransmit to a payment processing network (or entity other than the merchant) additional data associated with the transaction. 
         [0031]    Embodiments of the invention further allow the payment processing network or other entity to bundle the decrypted additional data associated with specific transactions for the merchant. The merchant may subscribe to services from the payment processing network or other entity to receive decrypted additional data associated with the transactions and/or corresponding users. By requiring the merchants to subscribe in order to access the additional data, the security of the system is increased. The transaction-specific additional data may be used by the merchant for marketing or business research purposes. The additional data may be user profile information or feedback, such as a rating, which is associated with a specific transaction. Since the feedback is associated with a specific transaction, the merchant can easily determine what users do and do not like and target specific areas of improvement in their business to increase revenue. 
         [0032]    Embodiments of the invention provide the payment processing network with additional data related to a transaction conducted by a portable consumer device. As noted above, the additional data may be desirable for merchants to acquire. The payment processing network may sell this additional data to the merchants associated to the transactions. Additional data associated with the transaction may include data such as feedback, ratings, geographical location, profile information of the user, transaction history, or any other data from the user at the time of the transaction that the merchant may not otherwise be able to obtain. Other examples of additional data may include surveys. For example, in embodiments of the invention, the consumer may be prompted to answer a survey to provide preferences on what type of food, shopping, cars, music, etc., the consumer likes. Thus, in some embodiments, the additional data need not relate to the specific merchant at which the current transaction is conducted. The additional data may also have value to entities (e.g., marketers) other than the merchant. 
         [0033]    Prior to discussing various embodiments in greater detail, several terms will be described to provide a better understanding of this disclosure. 
         [0034]    As used herein, a “portable consumer device” may include any suitable device that may be used to conduct a financial transaction. A portable consumer device may be in any suitable form. For example, suitable portable consumer devices can be hand-held and compact so that they can fit into a consumer&#39;s wallet and/or pocket (e.g., pocket-sized). They may include smart cards, keychain devices (such as the Speedpass™ commercially available from Exxon-Mobil Corp.), etc. Other examples of portable consumer devices include mobile communication devices, payment cards, security cards, access cards, smart media, transponders, etc. If the portable consumer device is in the form of a debit, credit, or smartcard, the portable consumer device may also optionally have features such as magnetic stripes. Such portable consumer devices can operate in either a contact or contactless mode. 
         [0035]    A “mobile communication device” (or “mobile device”) as used herein may include any suitable electronic device that is capable of electronic communication. An exemplary electronic device is capable of being transported to a merchant location and/or capable of being moved to different positions within the merchant location. As discussed below, a mobile communication device may include a computing device, and further may be used to capture images of products at one or more merchant locations. Examples of mobile devices include smart phones, tablet computer, laptop computers, personal digital assistants, etc. 
         [0036]    A “payment card” as used herein may include a card with an integrated chip. It may be capable of communicating with an access device. The payment card may comprise payment data, such as an account identifier, security code, card verification value, dynamic card verification value, and expiration date. Additional information that may be stored on the payment card may include personal data identifying an authorized user of the payment card, such as a photo, or other identifying information. The payment card can also be a debit device (e.g., a debit card), credit device (e.g., a credit card), or stored value device (e.g., a stored value card). They may include smart cards, credit or debit cards (with a magnetic stripe), etc. 
         [0037]    As used herein, an “access device” may be any suitable device for communicating with a merchant computer or payment processing network, and for interacting with a payment device, a user computer apparatus, and/or a user mobile device. An access device may generally be located in any suitable location, such as at the location of a merchant. An access device may be in any suitable form. Some examples of access devices include POS devices, cellular phones, PDAs, personal computers (PCs), tablet PCs, hand-held specialized readers, set-top boxes, electronic cash registers (ECRs), automated teller machines (ATMs), virtual cash registers (VCRs), kiosks, security systems, access systems, Websites, and the like. An access device may use any suitable contact or contactless mode of operation to send or receive data from, or associated with, a payment device and/or a user mobile device. In some embodiments, where an access device may comprise a POS terminal, any suitable POS terminal may be used and may include a reader, a processor, and a computer-readable medium. A reader may include any suitable contact or contactless mode of operation. For example, exemplary card readers can include radio frequency (RF) antennas, optical scanners, bar code readers, or magnetic stripe readers to interact with a payment device and/or mobile device. 
         [0038]    As used herein, “transaction data” may include data relating to a transaction. In some embodiments, transaction data may include data as contained in an authorization request message, contained in an authorization response message, and/or generated by the processing of an authorization message. For example, transaction data can include a unique transaction identifier, transaction date and time, account number, transaction class code (e.g., credit, debit, ATM, prepaid, etc.), merchant code (e.g., MVV, DBA, etc.), ATM code, acquirer code, acquirer processor code, issuer code (e.g., BIN, etc.), issuer processor code, authorization category code (e.g., approved, declined, rejected, etc.), one or more error codes, transaction amount (e.g., settlement amount), cardholder or account holder information (e.g., name, date of birth, address, phone number, etc.), card verification value (CVV), expiration date, loyalty account information, and other information relating to the transaction. 
         [0039]    “Additional data” can include data that is not typically included in conducting a transaction, and is not typically transmitted with the transaction data in an authorization request message. Examples of additional data may include, feedback, ratings, geographical location, personal information of the user (e.g., image), shopping profile of the user, authentication message of the user (e.g., cardholder), device ID, or other data associated with the transaction and/or user. Additional data may be collected from the user at a time of a transaction, and may be encrypted. Also, in some embodiments, additional data is specifically created and entered by the user at the time of the transaction. 
         [0040]    To prevent tampering or falsifying of the additional data, the additional data may be encrypted. Encryption allows merchants, issuers, acquirers, and other entities to verify the identity of the source of the information (e.g., the additional data is from a valid user), without allowing other parties, such as the merchant, to tamper with the data. 
         [0041]    An “authorization request message” may include an electronic message that is sent to a payment processing network and/or an issuer of a payment card to request authorization for a transaction. An authorization request message according to some embodiments may comply with ISO 8583, which is a standard for systems that exchange electronic transaction information associated with a payment made by a consumer using a payment device or payment account. The authorization request message may include an issuer account identifier that may be associated with a payment device or payment account. An authorization request message may also comprise additional data elements corresponding to “identification information” including, by way of example only: a service code, a CVV (card verification value), a dCVV (dynamic card verification value), an expiration date, etc. 
         [0042]    An “authorization response message” may be an electronic message reply to an authorization request message. The authorization response message may be generated by an issuing financial institution or a payment processing network. The authorization response message may include, by way of example only, one or more of the following status indicators: Approval—transaction was approved; Decline—transaction was not approved; or Call Center—response pending more information, merchant must call the toll-free authorization phone number. The authorization response message may also include an authorization code, which may be a code that a credit card issuing bank returns in response to an authorization request message in an electronic message (either directly or through the payment processing network) to the merchant&#39;s access device (e.g. POS equipment) that indicates approval of the transaction. The code may serve as proof of authorization. As noted above, in some embodiments, a payment processing network may generate or forward the authorization response message to the merchant. 
         [0043]    As used herein, a “payment processing network” may include data processing subsystems, networks, and operations used to support and deliver authorization services, exception file services, and clearing and settlement services. An exemplary payment processing network may include VisaNet™. Payment processing networks such as VisaNet™ are able to process credit card transactions, debit card transaction, and other types of commercial transactions. VisaNet™, in particular, includes a VIP system (Visa Integrated Payments system) which processes authorization requests and a Base II system which performs clearing and settlement services. 
         [0044]    As used herein, an “acquirer computer” may be an entity that processes electronic payment transactions on behalf of an acquirer, or that cooperates with an acquirer to process electronic payment transactions. 
         [0045]    As used herein, an “issuer computer” may be an entity that that processes electronic payment transactions on behalf of an issuer, or that cooperates with an issuer to process electronic payment transactions. An issuer processor may include data processing subsystems, networks, and operations used to support and deliver various services such as network gateway, risk management, program management, authorization, exception file, and clearing and settlement services. 
         [0046]    As used herein, a “server computer” may include a powerful computer or cluster of computers. For example, the server computer can be a large mainframe, a minicomputer cluster, or a group of servers functioning as a unit. In one example, the server computer may be a database server coupled to a Web server. The server computer may be coupled to one or more databases and may include any hardware, software, other logic, or combination of the preceding for servicing the requests from one or more client computers. The server computer may comprise one or more computational apparatuses and may use any of a variety of computing structures, arrangements, and compilations for servicing the requests from one or more client computers. 
         [0047]      FIG. 1  shows a block diagram illustrating a system for conducting a transaction according to an embodiment of the invention. System  10  comprises a user  30  with a portable consumer device, such as a mobile device  36 , an access device  34 , a merchant computer  22 , an acquirer computer  24 , a payment processing network (e.g., VisaNet)  26 , and an issuer computer  28 . One or more of these components can be operatively coupled together. The system  10  may also comprise a ratings server  29  including a ratings database  31 . The ratings server  29  and ratings database  31  may be operated by another entity external to the payment processing network  26 , or may be operated internally by the payment processing network  26 . Further details about each of these components are provide below. 
         [0048]    In an embodiment of the invention, the user  30  may wish to conduct a transaction. At some point during the transaction, the access device  34  may provide a prompt to the user  30  for additional data associated with the transaction. The prompt for the rating  36 ( a ) may be displayed on the access device  34 . The user  30  may then enter a rating into the mobile device  36  or the access device  34 . For example, the user  30  may choose a rating for the transaction between 1 and 5 stars, and the user  30  may select a 4 star rating for the transaction. The information regarding the 4 star rating may be entered into the access device  34  or the mobile device  36 . If the additional data was not entered into the mobile device  36 , the access device  34  may transmit the ratings information to the mobile device  36 . 
         [0049]    Once received, the mobile device  36  may encrypt the rating and transmit the encrypted rating  36 ( b ) to the access device  34 . The mobile device  36  may communicate with the access device  34  in either a wired or wireless (e.g., contactless) mode. 
         [0050]    In other embodiments of the invention, the prompt for rating  36 ( a ) may be any suitable prompt for additional data that is typically not included in a conventional payment transaction. Other examples of additional data include user feedback, geographical location, authentication messages, etc. 
         [0051]    After it receives the encrypted data, the access device  34  generates an authorization request message  34 ( a ) including the encrypted rating  36 ( b ). The authorization request message  34 ( a ) with the encrypted rating  36 ( b ) is then transmitted from the access device  34  to a merchant computer  22 , which transmits it to an acquirer computer  24 , and to a server computer in the payment processing network  26 . 
         [0052]    The server computer in the payment processing network (e.g., VisaNet)  26  may remove the encrypted rating  36 ( b ) from the authorization request message  34 ( a ), and decrypt the encrypted rating. The payment processing network  26  may then generate a second authorization request message  26 ( a ) without the encrypted rating  36 ( b ). The second authorization request message  26 ( a ) comprises typical transaction data for authorization, and is then transmitted to the issuer computer  28 . The issuer computer  28  then determines whether or not to approve or decline the transaction. 
         [0053]    In response, the issuer computer  28  generates an authorization response message  28 ( a ), approving or declining the transaction, and transmits the authorization response message  28 ( a ) to the payment processing network  26 . 
         [0054]    The payment processing network  26 , after removing the encrypted additional data  36 ( a ) from the authorization request message  34 ( a ) and decrypting it, may determine whether or not the merchant has requested the ratings information. The merchant may have subscribed to a subscription service to receive the decrypted additional data (e.g., ratings) associated with the transactions. 
         [0055]    In some embodiments, the payment processing network  26  may generate and transmit a subscription query  26 ( c ) to a ratings server computer  29  or other entity, coupled to a ratings database  31 . If the ratings server computer  29  determines that the merchant is a subscriber, and is therefore eligible to receive the decrypted additional data, the decrypted rating and an associated transaction ID  29 ( a ) are stored in the ratings database  31 . In other embodiments, it is desirable to store the data even if the merchant is not subscribed, because other parties may desire access to the data. Other transaction data may be stored and associated with the decrypted rating, including an account identifier, merchant ID, transaction details (e.g., products purchased or services received), and transaction amount. The ratings server computer  29  may generate and transmit a subscription response  29 ( b ) to the payment processing network  26  to confirm whether or not the merchant is a subscriber. 
         [0056]    Although the ratings server  29  and the ratings database  31  are shown as being outside of the payment processing network  26 , the ratings server  29  and the ratings database  31  may be present in the payment processing network  26  in other embodiments of the invention. 
         [0057]    When the server computer in the payment processing network  26  receives the subscription response  29 ( b ) with confirmation that the merchant is subscribed and is therefore eligible to receive the decrypted additional data (e.g., decrypted ratings), the payment processing network  26  incorporates the decrypted rating  36 ( c ) with the authorization response message  28 ( a ) from the issuer computer  28  to generate a modified authorization response message  26 ( b ). The authorization response message  26 ( b ) comprises the decrypted rating  36 ( c ) and is transmitted through the acquirer computer  24 , and to the merchant computer  22 . The merchant computer  22  can remove the decrypted rating  36 ( c ) from the authorization response message  26 ( b ), store it in a local database (not shown) along with the transaction data for future analysis. It can also forward the authorization response message  26 ( b ) to the access device  34 . 
         [0058]    In some embodiments of the invention, the decrypted rating may be transmitted directly to the merchant computer  22  from the payment processing network  26 , and may be transmitted separately from the authorization response message. 
         [0059]      FIG. 2  shows a flowchart illustrating a method of conducting a transaction according to the embodiment of the invention described above. A user  30  may possess a mobile device  36  to conduct the transaction with a merchant  22  at an access device  34 . 
         [0060]    In step A 1 , the user  30  initiates a payment transaction with the merchant at the access device  34 . For example, the user  30  may bring items at a retail store to a checkout counter to initiate a transaction to purchase the items. 
         [0061]    In step A 2 , the user  30  may be requested by an access device  34  to present the mobile device  36  for payment. For example, after all the items have been scanned and the transaction details, including total amount, are displayed on the access device  34 , the access device  34  may request a form of payment to complete the transaction to purchase the items. 
         [0062]    In step A 3 , the user  30  presents the mobile device  36  for payment. The mobile device  36  may communicate with the access device  34  by tapping or touching the mobile device on the access device  34 , or holding the mobile device  36  in proximity of the access device  34  so that they can communicate with each other wirelessly or through other contactless means. 
         [0063]    In step A 4 , the user  30  may be prompted for additional data, such as a rating or other feedback. The prompt could happen before or after the start of the transaction. The additional data may also include additional payment, personal user, or other additional data associated with the transaction. In some embodiments, the user  30  may receive a prompt on the access device  34  to interact the mobile device  36  with the access device  34 . The user&#39;s mobile device  36 , when in contact with the access device  34 , may communicate with the access device  34  to display the prompt onto the mobile device  36 . The mobile device  36  may communicate with the access device  34  by contactless means (e.g., wireless communication). 
         [0064]    In step A 5 , the additional data (e.g., rating) from the user  30  is encrypted by the mobile device  36  and the encrypted data is transmitted to the access device  34 . 
         [0065]    In step A 6 , the access device  34  receives the encrypted additional data from the portable consumer device (e.g., mobile device  36 ) of the user, and generates an authorization request message to transmit to the payment processing network  26 . The authorization request message may include transaction data typically contained in an authorization request message. Transaction data may include payment information (e.g., payment card identifier, card verification value, etc.) In embodiments of the invention, the encrypted additional data (e.g., rating) is bundled and included with the transaction data in the authorization request message transmission. In this way, the additional data may be collected in a secure manner without increasing the number of messages that are required to be transmitted or received. As such, only minimal additional demand is placed on computing resources in the system. In addition, it allows existing systems to perform methods in accordance with the invention, while requiring no, or minimal, modification. 
         [0066]    In step A 7 , the payment processing network (e.g., VisaNet)  26  receives the authorization request message with the encrypted additional data (e.g., rating). The payment processing network  26  initiates authorization of the transaction using transaction data from the authorization request message. Additionally, the encrypted additional data (e.g., rating) is optionally removed from the authorization request message and decrypted, associated with the specific transaction using a transaction ID, and stored in a database with the associated transaction. The payment processing network  26  also determines if the merchant is subscribed to receive decrypted additional data (e.g., rating) from the payment processing network  26 . In other variations of the invention, the payment processing network  26  may communicate with another entity comprising a server computer (e.g., ratings server  29  of  FIG. 1 ) and a database (e.g., ratings database  31  of  FIG. 1 ) to determine whether the merchant is subscribed and therefore eligible to receive decrypted additional data associated with the transaction. 
         [0067]    In step A 8 , after receiving the authorization request message including the encrypted additional data, the payment processing network  26  (e.g., VisaNet) removes the encrypted additional data, and generates an authorization request message without the encrypted additional data. The authorization request message without the encrypted additional data is transmitted to an issuer computer  28 . The issuer computer  28  determined whether to authorize the transaction, and generates an authorization response message indicating whether the transaction is approved or declined. 
         [0068]    In step A 9 , the issuer computer  28  transmits the authorization response message to the payment processing network  26 , in which the authorization response message contains an indication of whether the transaction is approved or declined. 
         [0069]    In step A 10 , the payment processing network  26  generates an authorization response message to be transmitted to the merchant computer  22 . If in step A 7  it has been determined that the merchant is a subscriber, the payment processing network  203  will bundle the decrypted additional data with the authorization response message. The payment processing network  26  will then transmit the authorization response message with the decrypted additional data (e.g., rating) to the merchant computer  22 . If the merchant is not a subscriber, then the payment processing network  26  will generate and transmit the authorization response message to the merchant computer  22  without the decrypted data. 
         [0070]    The decrypted additional data is removed from the authorization response message and stored at the merchant computer for the merchant to analyze and use. An authorization response message without the decrypted additional data is then forwarded to the access device  34  to be displayed to the user  30  that the transaction is complete. 
         [0071]      FIG. 3  shows a block diagram illustrating a system for conducting a transaction according to an embodiment of the invention. System  30  comprises a user  30  with a payment card  32 . An access device  34 , a merchant computer  22 , an acquirer computer  24 , a payment processing network (e.g., VisaNet)  26 , and an issuer computer  28  may all be operatively coupled together. The system  10  may also comprise an additional data server  40  and an additional data database  42 . Further details about each of these components are provided below. 
         [0072]    In an embodiment of the invention, the user  30  may wish to conduct a transaction. At some point during the transaction, the access device  34  may provide a prompt to the user  30  for additional data associated with the transaction. The prompt for the additional information  46 ( a ) may be displayed on the access device  34 . The user  30  may then enter the additional information into the access device  34 . For example, the user  30  may provide additional information such as authentication data (e.g., a password) to the access device  34 . It might be useful to encrypt additional information such as a password, so that the merchant is unable to obtain the password. This increases the level of security in case the merchant or the merchant&#39;s employee is deemed untrustworthy. 
         [0073]    In other embodiments, the prompt could come from the payment card  32  to be displayed on the access device  34 . The access device  34  then sends the collected additional data to the payment card  32  so that it can be encrypted. 
         [0074]    Once received, the payment card  32  may encrypt the additional information and can transmit the encrypted additional data  46 ( b ) to the access device  34 . The payment card  34  may communicate with the access device  34  in either a wired or wireless (e.g., contactless) mode. 
         [0075]    In other embodiments of the invention, the prompt for the additional information  46 ( a ) may be any suitable prompt for additional data that is typically not included in a conventional payment transaction. Other examples of additional data include user feedback, geographical location, authentication messages, etc. 
         [0076]    After it receives the encrypted additional data, the access device  34  generates an authorization request message  34 ( a ) including the encrypted additional data  46 ( b ). The authorization request message  44 ( a ) with the encrypted additional information  46 ( b ) is then transmitted from the access device  34  to a merchant computer  22 , which transmits it to an acquirer computer  24 , and to a server computer in the payment processing network  26 . 
         [0077]    The server computer in the payment processing network (e.g., VisaNet)  26  may remove the encrypted additional information  46 ( b ) from the authorization request message  44 ( a ), and may decrypt the encrypted additional data. The payment processing network  26  may then generate a second authorization request message  48 ( a ) without the encrypted additional data  46 ( b ). The second authorization request message  48 ( a ) comprises typical transaction data for authorization, which is then transmitted to the issuer computer  28 . The issuer computer  28  then determines whether or not to approve or decline the transaction. 
         [0078]    In response, the issuer computer  28  generates an authorization response message  48 ( b ), approving or declining the transaction, and transmits the authorization response message  48 ( b ) to the payment processing network  26 . 
         [0079]    The payment processing network  26 , after removing the encrypted additional data  34 ( a ) from the authorization request message  44 ( a ) and decrypting it, may determine whether or not the merchant has requested the additional information. The merchant may have subscribed to a subscription service to receive the additional data associated with the transactions. 
         [0080]    In some embodiments, the payment processing network  26  may generate and transmit a subscription query  40 ( c ) to an additional data server computer  40  or other entity, coupled to an additional data database  42 . If the additional data server computer  40  determines that the merchant is subscribed, and is therefore eligible to receive the decrypted additional data, the decrypted additional data and an associated transaction ID  40 ( b ) are stored in the additional data database  42 . Other transaction data may be stored and associated with the decrypted additional data including an account identifier, merchant ID, transaction details (e.g., products purchased or services received), and transaction amount. The additional data server computer  40  may generate and transmit a subscription response  40 ( c ) to the payment processing network  26  to confirm whether the merchant is subscribed or not. 
         [0081]    Although the additional data server computer  40  and the additional data database  42  are shown as being outside of the payment processing network  26 , they may be present in the payment processing network  26  in other embodiments of the invention. 
         [0082]    When the server computer in the payment processing network  26  receives the subscription response  40 ( c ) with confirmation that the merchant is subscribed and is therefore eligible to receive the decrypted additional data (e.g., decrypted ratings), the payment processing network  26  incorporates the decrypted additional data  46 ( c ) with the authorization response message  48 ( b ) from the issuer computer  28  to generate a modified authorization response message  48 ( c ). In other embodiments, other entities including a payment processing network may generate an authorization response message on behalf of an issuer. The authorization response message  48 ( b ) comprises the decrypted additional data  46 ( c ) and is transmitted through the acquirer computer  24 , and to the merchant computer  22 . The merchant computer  22  can remove the decrypted additional data  36 ( c ) from the authorization response message  48 ( c ), and store it in a local database (not shown) for future analysis. It can also forward the authorization response message  48 ( c ) to the access device  34 . 
         [0083]    In some embodiments of the invention, the decrypted rating may be transmitted directly to the merchant computer  22  from the payment processing network  26 , and may be transmitted separately from the authorization response message. 
         [0084]      FIG. 4  shows a flowchart illustrating a method of conducting a transaction according to the embodiment of the invention described above corresponding to  FIG. 3 . A user  30  may possess a payment card  32  to conduct the transaction with a merchant at an access device  34 . 
         [0085]    In step B 1 , the user  30  initiates a payment transaction with the merchant at the access device  34 . For example, the user  30  may have just finished a meal at a restaurant and is ready to pay for the meal, thus asking a waiter for a bill. 
         [0086]    In step B 2 , the user  30  may be presented with the bill, and an access device  34 , such as a mobile merchant POS terminal, in which a payment card  32  is requested. 
         [0087]    In step B 3 , the user  30  presents the payment card  32  for payment. In some embodiments the payment card  32  may communicate with the access device  34  by tapping or touching payment card  32  on the access device  34 , or inserting the payment card  32  into the access device. Where the payment card  32  is a contactless payment card with an integrated chip, B 3  may include holding the payment card  32  with integrated chip in proximity of the access device so that they can communicate with each other wirelessly or through other contactless means. 
         [0088]    In step B 4 , the user  30  may be prompted for additional data, such as geographical location, preferences, user image, shopping profile, or other additional data associated with the transaction. The additional data may also include additional payment information, personal user information, etc., or other additional data associated with the transaction. In some embodiments, the additional data may be obtained directly from the payment card  32  without a prompt to the user (e.g., geo-location data may be transmitted by a payment card or mobile device, encrypted and sent to the access device). In some embodiments, the user  30  may receive a prompt on the access device  34  to enter the additional data and then interact the payment device  32  with the access device  34 , such that the user&#39;s payment card  32 , when in contact with the access device  34 , may communicate with the access device  34  to receive the additional data from the access device  34 . The payment card  32  may communicate with the access device  34  by contactless means (e.g., wireless communication). 
         [0089]    In step B 5 , the additional data entered by user  30  on the access device  34  and received by the payment card  32  is encrypted by the payment card  32  and the encrypted additional data is transmitted to the access device  34 . The user&#39;s payment card  32  encrypts and transmits the encrypted additional data to the access device  34 . No data from the user  30  or the user&#39;s payment card  32  is stored at the access device  34 . 
         [0090]    In step B 4 , the access device  34  transmits the additional data to the payment card  32 . In step B 5 , the access device  34  receives the encrypted data from the payment card  32 . These steps can coincide with a standard request for a cryptogram from the payment card  32 , and the subsequent transmission of the cryptogram from the card  32  to the access device  34 . In the cryptogram request, terminal data (e.g., a terminal unpredictable number and a transaction amount) may be transmitted from the access device  34  to the payment card  32 . A processor in the payment card  32  may then generate a cryptogram using an application transaction counter on the payment card and the terminal data. This cryptogram is then transmitted from the payment card to the access device  32 . By incorporating the transmission of the additional data to the card with the cryptogram request, and by incorporating the transmission of the encrypted additional data with the transmission of the cryptogram, the additional data encryption process can be efficiently incorporated into an pre-existing communication process without requiring the creation of additional communication processes. 
         [0091]    Further details regarding known interaction protocols between a payment card and an access device (e.g., a payment terminal) can be found in U.S. patent application Ser. No. 11/536,307, filed on Sep. 28, 2006, which is herein incorporated by reference in its entirety. 
         [0092]    In step B 6 , the access device  34  receives the encrypted additional data from the payment card  32  of the user, and generates an authorization request message to transmit to the payment processing network  26 . The authorization request message may include transaction data typically contained in an authorization request message. Transaction data may include user information (e.g., name, billing address, mobile device identifier, etc.), and payment information (e.g., payment card identifier, card verification value, etc.) In embodiments of the invention, the encrypted additional data is bundled and included with the transaction data in the authorization request message transmission. 
         [0093]    In step B 7 , the payment processing network (e.g., VisaNet)  26  receives the authorization request message with the encrypted additional data. The payment processing network  26  initiates authorization of the transaction using transaction data from the authorization request message. Additionally, the encrypted additional data is removed from the authorization request message and decrypted, associated with the specific transaction using a transaction ID, and stored in a database with the associated transaction. The payment processing network  26  also determines if the merchant is subscribed to receive decrypted additional data from the payment processing network  26 . In other variations of the invention, the payment processing network  26  may communicate with another entity comprising a server computer (e.g., additional data server  40  of  FIG. 3 ) and a database (e.g., additional data database  42  of  FIG. 3 ) to determine whether the merchant is subscribed and therefore eligible to receive decrypted additional data associated with the transaction. 
         [0094]    In step B 8 , after receiving the authorization request message including the encrypted additional data, the payment processing network  26  (e.g., VisaNet) removes the encrypted additional data, and generates an authorization request message without the encrypted additional data. The authorization request message is transmitted to an issuer computer  28 . The issuer computer  28  determined whether to authorize the transaction, and generates an authorization response message indicating whether the transaction is approved or declined. 
         [0095]    In step B 9 , the issuer computer  28  transmits the authorization response message to the payment processing network  26 , in which the authorization response message contains an indication of whether the transaction is approved or declined. In other embodiments, the payment processing network  26  may generate and transmit the authorization response message on behalf of the issuer. 
         [0096]    In step B 10 , the payment processing network  26  generates an authorization response message to be transmitted to the merchant computer  22 . If in step B 7  it has been determined that the merchant is a subscriber, the payment processing network  26  will bundle the decrypted additional data with the authorization response message. The payment processing network  26  will then transmit the authorization response message with the decrypted additional data to the merchant computer  22 . If the merchant is not a subscriber, then the payment processing network  26  will generate and transmit the authorization response message to the merchant computer  22  without the decrypted additional data. 
         [0097]    The decrypted additional data is removed from the authorization response message and stored at the merchant computer for the merchant to analyze and use. An authorization response message without the decrypted additional data is then forwarded to the access device  34  to be displayed to the user  30  that the transaction is complete in step B 11 . In some embodiments, the authorization response message may pass from the access device  34 , back to the payment card. 
         [0098]      FIG. 5  shows a block diagram illustrating a system according to an embodiment of the invention. System  50  comprises a user  30  with a portable consumer device such as a mobile device  36 . An access device  34 , a merchant computer  22 , an acquirer computer  24 , a payment processing network (e.g., VisaNet)  26 , and an issuer computer  28  are operatively coupled together. The mobile device  36  may be enabled to communicate over a mobile gateway  27  to the payment processing network  26 . The system  50  may also comprise a ratings server computer  29  including a ratings database  31 . The ratings server computer  29  and ratings database  31  may be operated by another entity external to the payment processing network  26 , or may be operated internally by the payment processing network  26 . 
         [0099]    In an embodiment of the invention, the user  30  may wish to conduct a transaction. The user  30  may use a mobile communication device  36  to interact with the access device  34 . The access device  34  and the mobile communication device  36  can communicate via a short range (e.g., less than 5 feet, and preferably less than 0.5 feet) contactless communication protocol (e.g., short range RF, Bluetooth™, IR, etc.), or may operate in a contact mode. The access device  34  generates an authorization request message  34 ( a ). The authorization request message  34 ( a ) is then sent from the access device  34  to a merchant computer  22 , transmitted to an acquirer computer  24 , and to a payment processing network  26 . 
         [0100]    The payment processing network  26  may then provide a prompt for additional data associated with the transaction to the mobile device  36  of the user  30 , communicating via a mobile gateway  27 . For example, the mobile device  36  may display a prompt for additional data, such as a rating of the transaction. A prompt for a rating  36 ( a ) may be displayed on the mobile device  36 , and the user  30  may enter a rating into the mobile device  36 . For example, the user  30  may choose a rating for the transaction between 1 and 5 stars, and the user  30  may select a 4 star rating for the transaction. The mobile device  36  may encrypt the rating and transmit the encrypted rating  36 ( b ) to the payment processing network  26  via the mobile gateway  27 . The mobile device  36  may communicate with a server computer in the payment processing network  26  using a long range communication protocol. For instance, the mobile device  36  may comprise an antenna which will allow it to communicate with the server computer in the payment processing network  26  via a cellular telecommunications network. 
         [0101]    In other embodiments of the invention, the prompt for rating  36 ( a ) may be any prompt for additional data typically not included in transactional data, such as user feedback, geographical location, authentication messages, or other user data. 
         [0102]    The payment processing network (e.g., VisaNet)  26  may decrypt the encrypted rating. The payment processing network  26  may then forward an authorization request message  26 ( a ) comprising typical transaction data for authorization, and transmit it to an issuer computer  28 , wherein the issuer computer determines whether to approve or decline the transaction. In response, the issuer computer  28  generates an authorization response message  28 ( a ), approving or declining the transaction, and transmits the authorization response message  28 ( a ) to the payment processing network  26 . In other embodiments, the payment processing network  26  may generate and send an authorization response message on behalf of the issuer. 
         [0103]    The payment processing network  26 , after receiving the encrypted additional data  36 ( b ) from the mobile device  36  and decrypting it, may determine whether the merchant is subscribed to receive decrypted additional data, such as ratings, associated with the transactions. The payment processing network  26  may generate and transmit a subscription query  26 ( c ) to a ratings server  29  or other entity, coupled to a ratings database  31 . If the ratings server  29  determines that the merchant is subscribed, and therefore is eligible to receive decrypted additional data, the decrypted rating and an associated transaction ID  29 ( a ) are stored in the ratings database  31 . In some embodiments, the additional data is stored and/or processed whether or not there are active subscribers so such additional data. Other transaction data may be stored and associated with the decrypted rating, including an account identifier, merchant ID, transaction details (e.g., products purchased or services received), and transaction amount. The ratings server  29  may generate and transmit a subscription response  29 ( b ) to the payment processing network  26  to confirm whether the merchant is subscribed or not. 
         [0104]    In other embodiments of the invention, the ratings server  29  and ratings database  31  may be operated by the payment processing network, thus determining whether the merchant is a subscriber may be done internally within the payment processing network. 
         [0105]    When the payment processing network  26  receives the subscription response  29 ( b ) with confirmation that the merchant is subscribed and is therefore eligible to receive decrypted additional data, such as ratings, the payment processing network  26  directly transmits the decrypted additional data (e.g., ratings) to the merchant computer  22 . The decrypted additional data may be transmitted separately from the authorization response message  26 ( b ). The payment processing network  26  forwards the authorization response message  26 ( b ) to the access device  34  via the acquirer computer  24  and merchant computer  22 . The decrypted rating  36 ( c ) may be stored and used by the merchant computer  22  for analysis. 
         [0106]      FIG. 6  shows a flowchart illustrating a method of conducting a transaction according to the embodiment of the invention described above corresponding to  FIG. 5 . A user  30  may possess a mobile device  36  to conduct the transaction with a merchant  22  at an access device  34 . 
         [0107]    In step C 1 , the user  30  initiates a payment transaction with the merchant at the access device  34 . For example, the user  30  may bring items at a retail store to a checkout counter to initiate a transaction to purchase the items. After all the items have been scanned and the transaction details, including total amount, are displayed on the access device  34 , the access device  34  may initiate processing the transaction. 
         [0108]    In step C 2 , the access device generates an authorization request message to transmit to the payment processing network  26 . The authorization request message may include transaction data typically contained in an authorization request message. Transaction data may include payment information (e.g., payment card identifier, card verification value, etc.) The payment processing network (e.g., VisaNet)  26  receives the authorization request message. 
         [0109]    In step C 3 , after the payment processing network receives an authorization request message from the access device  34 , the payment processing network  26  transmits a prompt to the mobile device  36  of the user  30  to request additional data. For example, the mobile device  36  may operate an application which is activated when a transaction is initiated with an access device  34 , such that after the payment processing network  26  receives an authorization request message, the mobile device  26  receives a prompt from the payment processing network  26  to display to the user  30  requesting additional data, such as a rating of the transaction. 
         [0110]    In step C 4 , the user  30  enters additional data into the mobile device  36 . The additional data may also include additional payment, personal user, or other additional data associated with the transaction. The additional data (e.g., rating) from the user  30  is encrypted by the mobile device  36  and the encrypted additional data is transmitted to the payment processing network  26 , bypassing the merchant computer  22  and the access device  34 . The encrypted additional data may pass through a mobile gateway  27 . 
         [0111]    In step C 5 , the payment processing network  26  initiates authorization of the transaction using transaction data from the authorization request message. Additionally, the encrypted additional data (e.g., rating) received from the mobile device  36  is decrypted, associated with the specific transaction using a transaction ID, and stored in a database with the associated transaction. The payment processing network  26  also determines if the merchant is subscribed to receive decrypted additional data (e.g., rating) from the payment processing network  26 . In other variations of the invention, the payment processing network  26  may communicate with another entity comprising a server computer (e.g., ratings server  29  of  FIG. 5 ) and a database (e.g., ratings database  31  of  FIG. 5 ) to determine whether the merchant is subscribed and therefore eligible to received decrypted additional data associated with the transaction. 
         [0112]    In step C 6 , after receiving the authorization request message, the payment processing network  26  (e.g., VisaNet) prepares an authorization request message to forward to an issuer computer  28 . The issuer computer  28  determined whether to authorize the transaction, and generates an authorization response message indicating whether the transaction is approved or declined. In other embodiments, the payment processing network  26  may act on behalf of the issuer. 
         [0113]    In step C 7 , the issuer computer  28  transmits the authorization response message to the payment processing network  26 , in which the authorization response message contains an indication of whether the transaction is approved or declined. 
         [0114]    In step C 8 , the payment processing network  26  generates an authorization response message to be transmitted to the merchant computer  22 . If in step A 5  it has been determined that the merchant is a subscriber, the payment processing network  26  may bundle the decrypted additional data with the authorization response message. In other embodiments, the decrypted additional data may be sent to the merchant computer  22  without being present in an authorization response message. The payment processing network  26  will then transmit the authorization response message with the decrypted additional data (e.g., rating) to the merchant computer  22 . If the merchant is not a subscriber, then the payment processing network  26  will generate and transmit the authorization response message to the merchant computer  22  without the decrypted additional data. 
         [0115]    The decrypted additional data is removed from the authorization response message and stored at the merchant computer for the merchant to analyze and use. An authorization response message without the decrypted additional data is then forwarded to the access device  34  to be displayed to the user  30  that the transaction is complete, in step C 9 . In some embodiments, the authorization response message may pass back to the mobile device  36  (e.g., via a mobile gateway  27  or through the access device  34 ). 
         [0116]    Although the embodiments of the invention described with reference to  FIGS. 5-6  include encrypting additional data in mobile device and then transmitting that encrypted data to a central server computer, such encryption is not required in this embodiments. For example, if the additional data is a rating, this additional data may be transmitted to a central server operating a review Website (e.g., Yelp™) The additional data may be linked to actual transaction data so that the review Website can verify that the reviews that are posted are tied to actual transactions and are not posted by people who did not conduct actual transactions. 
         [0117]    Provided below are descriptions of some devices (and components of those devices) that may be used in the systems and methods described above. These devices may be used, for instance, to receive, transmit, process, and/or store data related to any of the functionality described above. As would be appreciated by one of ordinary skill in the art, the devices described below may have only some of the components described below, or may have additional components. 
         [0118]    With reference to  FIG. 7 , an exemplary access device  34  is shown. The exemplary access device  34  is illustrated as comprising a plurality of hardware elements and software modules ( 301 - 310 ). However, it should be appreciated that this is provided for illustration purposes only, and each of the modules and associated functionality may be provided and/or performed by the same or different components. 
         [0119]    The access device  34  comprises a processor  301 , system memory  302  (which may comprise any combination of volatile and/or non-volatile memory such as, for example, buffer memory, RAM, DRAM, ROM, flash, or any other suitable memory device), and an external communication interface  303 . It may also include a display  304 , a contactless element  305 , input elements  306 , and a printer  307 , all operatively coupled to a processor  301 . In other embodiments, the access device  34  may also have a contact element (not shown) for contact based transactions, where the access device  34  contacts a portable consumer device. 
         [0120]    The access device  34  may comprise software modules, such as a calculation module  308 , using the transaction data to calculate transaction amounts, such as a subtotal, tax, discount, and total amount for the transaction. This transactional data may also be used to generate a receipt, performed by the receipt generation module  309 . Further, a printer  307  may print the receipt or other relevant transactional data, such as a coupon. 
         [0121]    The access device  34  may also comprise a contactless element  305  to communicate with suitable portable consumer devices. The access device  34  may receive information via input elements  306 , such as a keypad, from a user. Any received information may be transmitted to an appropriate module within the computer  300  (e.g. via a data bus line  350 ). 
         [0122]    The access device  34  may also receive additional data from a payment card, portable consumer device, or mobile device, communicating through the contactless element  305 . The received information, transaction information, and additional data may be used to generate an authorization request message in an appropriate data format in conformance with a transmission protocol so that the message may be sent to an issuer or payment processing network. The authorization request message may be generated by the authorization request generation software module  310 , and may then be passed to the external communication interface  303  for transmission. Thus, the access device  34  is capable of generating an authorization request message, and in some embodiments, the authorization request message comprises encrypted additional data. The access device  34  may then transmit the authorization request message to a server computer operated by a payment processing network, acquirer, and/or issuer. The external communication interface  303  may receive authorization response messages, or transmit an authorization request message to an issuer, acquirer, or payment processing network. Thus, the access device may also receive an authorization response message from the server computer operated by the payment processing network, issuer, and/or acquirer. 
         [0123]    With reference to  FIG. 8 , an exemplary server computer  200  in payment processing network  26  is shown. The exemplary server computer  200  is illustrated as comprising a plurality of hardware and software modules ( 201 - 211 ). 
         [0124]    The exemplary server computer  200  comprises a processor  201 , system memory  202  (which may comprise any combination of volatile and/or non-volatile memory such as, for example, buffer memory, RAM, DRAM, ROM, flash, or any other suitable memory device), and an external communication interface  203 . Moreover, one or more of the modules  204 - 211  may be disposed within one or more of the components of the system memory  202 , or may be disposed externally. 
         [0125]    The communication module  204  may be configured or programmed to receive and generate electronic messages. When an electronic message is received by the server computer  200  via external communication interface  203 , it may be passed to the communications module  204 . The communications module  204  may identify and parse the relevant data based on a particular messaging protocol used in the system  10 . The received information may comprise, for instance, identification information, transaction information, and/or any other information that the payment processing network  26  may utilize in authorizing a financial transaction or performing a settlement and clearing procedure. The communication module  204  may then transmit any received information to an appropriate module within the server computer  200  (e.g. via a data bus line  250 ). The communication module  204  may also receive information from one or more of the modules in server computer  200  and generate an electronic message in an appropriate data format in conformance with a transmission protocol used in the system  10  so that the message may be sent to one or more components within the system  10 . to an issuer computer  28  or merchant computer  22 ). The electronic message may then be passed to the external communication interface  203  for transmission. The electronic message may, for example, comprise an authorization response message (e.g. to be transmitted to a merchant conducting a transaction) or may be an authorization request message to be transmitted or forwarded to an issuer. 
         [0126]    The database look-up module  205  may be programmed or configured to perform some or all of the functionality associated with retrieving information from one or more databases. In this regard, the database look-up module  205  may receive requests from one or more of the modules of server  200  (such as communication module  204 , authorization module  208 , or settlement module  209 ) for information that may be stored in one or more of the databases. The database look-up module  205  may then determine and a query an appropriate database. 
         [0127]    The report generation module  207  may be programmed or configured to perform some or all of the functionality associated with generating a report regarding a user, an account, a transaction or transactions, or any other entity or category of information with regard to system  10 . This may include, for instance, identifying patterns (such as patterns that indicate a fraudulent transaction or transactions) and generating one or more alerts that may be sent (e.g. via communication module  204  and external communication interface  203 ) to one or more entities in the system  10 , including the user, merchant, or issuer. The report generation module may also, for example, request information from one or more of the databases via database look-up module  205 . 
         [0128]    The authorization module  208  may be configured or programmed to perform some or all the functionality associated with authorizing a financial transaction associated with an authorization request message. 
         [0129]    The payment processing network  26  may further comprise a decryption module  210 , which can receive encrypted additional data, and decrypt the additional data. In some embodiments of the invention, the additional data can be a rating of the transaction. The payment processing network  26  may also include a ratings module  211 , to parse, process, and interpret the decrypted ratings. For example, some ratings may be on a scale of 1 to 10, or 1 star to 5 stars. Additionally, the ratings module is not limited to only ratings, but the payment processing network  26  may include other modules for processing other types of additional data that may be encrypted/decrypted. 
         [0130]      FIG. 9  illustrates an exemplary ratings database  31 , or additional data database  42 . The ratings database  31  may comprise a look-up table of different fields  2202 - 2218 . Each field may include data relating to the transaction and/or the user, such as transaction ID  2202 , account identifier (e.g., PAN)  2204 , a rating of the transaction (or other additional data)  2206 , merchant ID  2210 , payment data (e.g., payment card information)  2212 , transaction amount  2214 , and/or transaction data (e.g., items purchased, services provided)  2208 . 
         [0131]    As shown in  FIG. 9 , additional data such as ratings, authentication data, surveys, etc. may be stored in a database with actual transaction data. By doing this, the additional data is more meaningful and authentic. 
         [0132]      FIG. 10  shows a block diagram showing components of an exemplary mobile device  36 . The exemplary mobile device  36  shown in  FIG. 10  may comprise a computer readable medium  36 ( b ) that be present within the body (or outer casing)  36 ( h ), or the computer readable medium  36 ( b ) could be detachable from the device The computer readable medium  36 ( b ) may be in the form of a memory that stores data. The memory may store information such as financial information, transit information (e.g., as in a subway or train pass), access information (e.g., access badges), serial numbers, mobile account information, and any other suitable information. In general, any of this information may be transmitted by the mobile device  36  (such as to an access device  34 ), via any suitable method, including the use of antenna  36 ( a ) or contactless element  36 ( g ). The body  36 ( h ) may be in the form a plastic substrate, housing, or other structure. 
         [0133]    In some embodiments, the mobile device  36  may further include a contactless element  36 ( g ), which is typically implemented in the form of a semiconductor chip (or other data storage element) with an associated wireless transfer (e.g., data transmission) element, such as an antenna (for long range communication). Contactless element  36 ( g ) may be coupled to (e.g., embedded within) the mobile device  36  and data or control instructions that are transmitted via a cellular network may be applied to the contactless element  36 ( g ) by means of a contactless element interface (not shown). The contactless element interface functions to permit the exchange of data and/or control instructions between the mobile device circuitry and an optional contactless element  36 ( g ), or between another device having a contactless element (e.g., a POS terminal or a payment device). Contactless element  36 ( g ) may be capable of transferring and receiving data using a short range wireless communication capability. As noted above, mobile device  36  may comprise components to both be the interrogator device (e.g. receiving data) and the interrogated device (e.g. sending data). Thus, the mobile device  36  may be capable of communicating and transferring data or control instructions via both cellular network (or any other suitable wireless network—e.g. the Internet or other data network) and short range communications. 
         [0134]    The mobile device  36  may also include a processor  36 ( c ) (e.g., a microprocessor) for processing the functions of the phone  36  and a display  36 ( d ) to allow a consumer to see phone numbers and other information and messages. The mobile device  36  may further include input elements  36 ( e ) to allow a user to input information into the device, a speaker  36 ( f ) to allow the user to hear voice communication, music, etc., and a microphone  36 ( i ) to allow the user to transmit her voice through the mobile device  36 . The mobile device  36  may also include an antenna  36 ( a ) for wireless data transfer (e.g., data transmission). 
         [0135]      FIG. 11  shows an exemplary non-transitory computer readable medium  36 ( b ) of the mobile device  36 . The computer readable medium  36 ( b ) may comprise several software modules. The mobile device  36  may be executing an operating system  3600  in operative association with a communication module  3602 . The operating system  3600  may enable the communication module  3602  to activate mobile communication capability on the mobile device, for example, enabling Wi-Fi or telecommunications connectivity. Further, the operating system  3600  may also be linked to a mobile application  3604 , to enable the mobile device to run the application to perform tasks. The mobile application  3604  according to embodiments of the invention may also include several software modules, including, but not limited to, a transaction module  601 , a payment card module  602 , a ratings module  603 , and an encryption module  604 . The transaction module  601  may process transaction details when the mobile device is being used to conduct a transaction. The payment card module  602  may store and manage payment cards (e.g., credit card, debit cards, bank accounts) for payment of the transaction conducted. The ratings module  603  may display and receive the rating, or alternatively in other embodiments, additional data associated with the transaction. Then the ratings module  603  may send the rating collected to the encryption module  604  to be encrypted before it is transmitted either to a payment processing network  26  or an access device  34 . The encryption module  604  (and any other encryption module described herein) may be use any suitable encryption process including DES, AES, etc. to encrypt the above-described additional data. 
         [0136]      FIG. 12(   a ) shows an example of a payment device  32 ″ in the form of a card. As shown, the payment device  32 ″ comprises a plastic substrate  32 ( m ). In some embodiments, an integrated chip  32 ( o ) (e.g., contactless chip) for interfacing with an access device  34  may be present on, or embedded within, the plastic substrate  32 ( m ). Consumer information  32 ( p ) such as an account number, expiration date, and/or a user name may be printed or embossed on the card. A magnetic stripe  32 ( n ) may also be on the plastic substrate  32 ( m ). In some embodiments, the payment device  32 ″ may comprise a microprocessor and/or memory chips with user data stored in them. 
         [0137]    As noted above and shown in  FIG. 12(   a ), the payment device  32 ″ may include both a magnetic stripe  32 ( n ) and an integrated chip  32 ( o ). In some embodiments, both the magnetic stripe  32 ( n ) and the integrated chip  32 ( o ) may be in the payment device  32 ″. In some embodiments, either the magnetic stripe  32 ( n ) or the integrated chip  32 ( o ) may be present in the payment device  32 ″. 
         [0138]    As shown in  FIG. 12(   b ), the integrated chip  32 ( o ), according to embodiments of the invention may also include several software modules, including, but not limited to, a payment data module  1306 , a ratings module  1308 , a contactless module  1304 , and an encryption module  1302 . The encryption module may have similar functionality as the encryption module  604  in  FIG. 11 . The contactless module  1304  may enable the payment card  32  to communicate with the access device  34 , in a wireless manner, such that holding the payment card in near proximity of the access device enables communication to conduct a transaction. The payment data module  1306  may store and manage payment data (e.g., credit card, debit cards, bank accounts) for payment of the transaction conducted. The additional data module  1308  may receive additional data associated with the transaction. Then the additional data module  1308  may send the additional data collected to the encryption module  1302  to be encrypted before it is transmitted to an access device  34 . 
         [0139]      FIG. 13  shows an exemplary computer apparatus according to embodiments of the invention, in which various embodiments may be implemented. The system  400  may be used to implement any of the computer systems described above (e.g., client computer, a server computer at the payment processing network, a computer apparatus at the merchant, etc.). The computer system  400  is shown comprising hardware elements that may be electrically coupled via a bus  424 . The hardware elements may include one or more central processing units (CPUs)  402 , one or more input devices  404  (e.g., a mouse, a keyboard, etc.), and one or more output devices  406  (e.g., a display device, a printer, etc.). The computer system  400  may also include one or more storage devices  408 . By way of example, the storage device(s)  408  can include devices such as disk drives, optical storage devices, solid-state storage device such as a random access memory (“RAM”) and/or a read-only memory (“ROM”), which can be programmable, flash-updateable and/or the like. 
         [0140]    The computer system  400  may additionally include a computer-readable storage media reader  412 , a communications system  414  (e.g., a modem, a network card (wireless or wired), an infra-red communication device, etc.), and working memory  418 , which may include RAM and ROM devices as described above. In some embodiments, the computer system  400  may also include a processing acceleration unit  416 , which can include a digital signal processor DSP, a special-purpose processor, and/or the like. 
         [0141]    The computer-readable storage media reader  412  can further be connected to a computer-readable storage medium  410 , together (and, optionally, in combination with storage device(s)  408 ) comprehensively representing remote, local, fixed, and/or removable storage devices plus storage media for temporarily and/or more permanently containing, storing, transmitting, and retrieving computer-readable information. The communications system  414  may permit data to be exchanged with the network and/or any other computer described above with respect to the system  400 . 
         [0142]    The computer system  400  may also comprise software elements, shown as being currently located within a working memory  418 , including an operating system  420  and/or other code  422 , such as an application program (which may be a client application, Web browser, mid-tier application, RDBMS, etc.). It should be appreciated that alternate embodiments of a computer system  400  may have numerous variations from that described above. For example, customized hardware might also be used and/or particular elements might be implemented in hardware, software (including portable software, such as applets), or both. Further, connection to other computing devices such as network input/output devices may be employed. 
         [0143]    Embodiments of the invention have many advantages. In embodiments of the invention, user feedback or additional data regarding a transaction and/or a merchant is protected from tampering by the merchant by encrypting the feedback at the time of the transaction before being transmitted to the merchant. This is accomplished by having the user enter additional data (e.g., rating) on a mobile device (or the information may originate in some other way from the mobile device) where it is encrypted. The encrypted additional data is then sent to a payment processing network (e.g., VisaNet) through an authorization request message from the merchant or by some other means (e.g., directly from the mobile device), as a proprietary additional data of the transaction. 
         [0144]    One example of such additional data is a rating of the merchant showing purchase experience (e.g., 0-5 stars). At the time of payment, a mobile payment application may display a menu on the mobile device display, where the user can enter or select 0 to 5 stars. In other embodiments, the user may use a payment device, such as a smartcard, that when communicating with a merchant POS terminal, can initiate the menu or other prompt for data to display on the merchant POS terminal. 
         [0145]    One advantage is that this additional data (e.g., rating) could be of value to the merchant accepting the payment transaction, but to prevent the merchant from tampering with the additional data, the additional data is encrypted, and the payment processing network controls access to the decrypted additional data. Only by subscribing to receive the decrypted additional data, the merchant may be allowed to access the data. 
         [0146]    The user benefits from providing additional data, such as rating his or her experience and sharing the rating with other users for future reference of where and with whom to conduct transactions with. There are existing means that allow users to rate and share their ratings with other users (e.g., Yelp, TripAdvisor, Google Latitude, and other similar services). However, user ratings are not fully protected from or for the merchant in currently existing services. Encrypting the additional data (e.g., rating) from the merchant ensures the security and protects the authenticity of user ratings, thus encouraging users to provide feedback and trust that their (and other users&#39;) feedback will be accurate and untampered with. 
         [0147]    In embodiments of the invention, the merchant can benefit from a rating associated with a single transaction and can be encrypted to ensure that it is not modified in transit, thus assuring the merchant that the rating is provided by a real consumer, rather than one who has signed into a review service and provides fraudulent ratings because that person was never a recent customer or was never a customer at all. 
         [0148]    Other advantages of embodiments of the invention relate to the merchant. Additional data, such as feedback or ratings from the user, may be of value to the merchant. In existing user feedback services (e.g., Yelp), user ratings are minimally useful to merchants because depending on the detail provided by the user in a review, the merchant may or may not be able to determine the specific transaction that the rating or review refers to. In embodiments of the invention, the data (e.g., rating) provides the merchant with more detail, since the user rating is directly associated to a specific transaction, unlike the ratings or reviews merchants may see on Yelp, or other rating services. Hence, this data is very valuable to the merchant because it may be used for more targeted marketing and/or improvements to the merchant&#39;s business to increase revenue. 
         [0149]    Other advantages of embodiments of the invention relate to the payment processing network. The payment processing network may operate a subscription service where the merchants are provided with various levels of access to the collected decrypted additional data (e.g., ratings), with the highest level of subscription providing a raw rating received at the time of the transaction, and with lower levels of subscription providing batched data that might relate merchant terminal IDs with ratings but not to individual purchases. Thus, merchant are encouraged to subscribe to the services provided by the payment processing network, increasing revenue for the payment processing network. 
         [0150]    Embodiments of the invention also establish and build the relationships between the user, the merchant, and the payment processing network, by providing protection, benefits, and advantages to all parties during a transaction. Furthermore, strengthening the relationship with the user establishes user loyalty with the merchant and the payment processing network, thus increasing repeated business with the merchant and other merchants who are subscribers and revenue for both merchants and the payment processing network. 
         [0151]    Embodiments of the invention may use existing technology and systems for payment processing, with no or minimal changes. In existing payment processing systems and methods, an authorization request message may contain a supplemental data field (e.g., Field  55 ), in which an encrypted additional data element (e.g., rating) may be stored. Thus, the merchant POS terminal may transmit the authorization request message to the payment processing network with the encrypted additional data contained in Field  55 . The payment processing network may be enabled to (1) understand Field  55  or other supplemental data field, (2) decrypt the encrypted additional data, and (3) store the decrypted additional data and/or send the decrypted additional data back in a generated authorization response message, depending on a subscription status of the merchant. The subscription status of the merchant may be determined by looking up a merchant identifier in a table or database at the payment processing network. 
         [0152]    In other embodiments of the invention, additional data may be collected from the user during a transaction. Examples of additional data are described below. 
         [0153]    The user or mobile device may provide where a transaction was last conducted. This may enable marketers, merchants, and/or other interested parties to gather data and trace patterns of where the user conducts transactions and how they may relate to types of transactions that are conducted. 
         [0154]    The mobile device may provide a picture of its registered user or account holder of a payment device used in the transaction, allowing the merchant to verify instantly with the person conducting the transaction to ensure that the mobile device has not been stolen. The picture may be digitally signed by an integrated chip in the mobile device or smartcard, so that the picture&#39;s integrity is protected and cannot be replaced with a new picture if stolen. The picture may be validated at the POS terminal with suitable software using the signature on the picture and displayed on the POS terminal. 
         [0155]    In embodiments of the invention, the payment processing network may comprise a system and process to manage, encrypt/decrypt, and sell the data received. This may be performed by a server computer comprising a processor and a computer-readable medium comprising code executable by the processor. 
         [0156]    In other embodiments of the invention, the payment processing network may be associated with a publisher of ratings, such as Yelp, Trip Advisor, Google (Latitude), Yahoo, Microsoft, Facebook or other entity. This may be beneficial so that users can go anywhere and see how merchants rate via multiple venues based on the user&#39;s preference. Further, the ratings data can be used by such sites to verify that comments are actually associated with real purchase transactions. This can make the reviews more authentic and reliable. 
         [0157]    In other embodiments, an electronic wallet may be used with a mobile communication device or other device, in conjunction with embodiments of the invention. The wallet may be used to conduct a transaction. An electronic wallet may be used in a variety of transactions, including but not limited to eCommerce, social networks, money transfer/personal payments, mobile commerce, proximity payments, gaming, and/or the like. For example, users may engage in eCommerce via the electronic wallet for retail purchases, digital goods purchases, and utility payments. Users, for example, may also use the electronic wallet to purchase games or gaming credits from gaming websites, and transfer funds to friends via social networks. Further, for example, users may also use the electronic wallet on a smart phone for retail purchases, buying digital goods, NFC/RF payments at point of sale (POS) terminals. 
         [0158]    In an exemplary transaction involving an electronic wallet, a consumer may submit an indication to purchase or transfer funds. For example, the consumer may visit a merchant website (e.g., Facebook.com, Amazon.com, etc.), and request to purchase an item from the website, transfer funds to a friend, and/or the like. The merchant website may determine whether the electronic wallet is authorized on its website, and may provide a list of payment options. If the merchant is registered with an electronic wallet server, the electronic wallet server may authorize the merchant to collect consumer credentials for login to the electronic wallet, and the merchant website may prompt the consumer to login to the electronic wallet. Otherwise, the merchant website may request the consumer to provide payment details for alternative payment options (e.g., credit card, debit card, PayPal account). 
         [0159]    The consumer may authorize submission of their wallet consumer credentials, such as, but not limited to a Wallet/User ID, a password, and/or the like. For example, the consumer may enter the Wallet/User ID and password into a pop-up window provided from the merchant website and/or electronic wallet server. In another example, the consumer may authorize the merchant website to provide the consumer credentials (e.g., previously stored in HTML5, cookies, etc.), to the electronic wallet server. In yet another example, the consumer may authorize the electronic wallet server, via a remote component running on the merchant website (e.g., a Java applet, etc.) to provide consumer credentials to the electronic wallet server for verification. 
         [0160]    When the consumer submits consumer credentials to log into the electronic wallet, the merchant website may forward the consumer credentials and transaction details to the electronic wallet server, which may determine the validity of the consumer credentials. If the consumer&#39;s credentials are not valid, the electronic wallet server may deny the payment request and send a notification of denial to the merchant website. In other embodiments, if the consumer provided credentials are valid, the electronic wallet server may process payment from the electronic wallet. For example, the electronic wallet server communicates with the consumer&#39;s bank account associated with the electronic wallet and requests a fund transfer of an indicated amount. The electronic wallet server may then store a transaction record. 
         [0161]    In some embodiments, after processing the payment, the electronic wallet server sends a payment confirmation notice to the merchant website, which in turn completes the order and stores the transaction record in the database. The merchant website may provide a confirmation page comprising transaction confirmation to the consumer.
