     In some embodiments, in the first method as described above, the first method may further include the step of presenting the portable consumer device to the first merchant to pay for the first transaction. 
     In some embodiments, in the first method as described above, the first method may further include the step of presenting the mobile device to the first merchant to pay for the first transaction. 
     In some embodiments, a first method may be provided that comprises the steps of: electronically sending by a mobile device a first request for first information to a server computer, where the first request is generated based on an interaction between the mobile device and a portable consumer device; electronically receiving at the mobile device the first information from the server computer; and electronically sending by the mobile device the first information to a merchant associated with a first transaction based on an interaction between the mobile device and an access device located at the merchant. 
     As discussed herein, systems, methods and apparatuses for conducting a financial transaction may be provided. In some embodiments, a consumer may receive a device verification value (e.g. a dCVV2 value) from a verification entity and may use the device verification value as evidence of the authenticity of a financial transaction. For example, during a first transaction, a consumer may use a mobile device (such as a mobile phone) to interact with a portable consumer device (e.g. by swiping a payment card or through use of a contactless interface) to retrieve information stored on the portable device (e.g. an account number, card verification values, expiration date, etc). This information (along with information related to the mobile device) may then be sent to a verification entity (such as, for example, a payment processing network or component thereof) as part of a request for a device verification value. The validation entity may perform one or more validation tests on the received request based on some or all of the information received from the mobile device, and may then return to the mobile device the device verification value (assuming the request is validated). The device verification value may thereby serve as an indication that the portable consumer device, the mobile device, and/or the consumer has been validated. However, embodiments are not so limited, and the mobile device may receive the device verification value in any suitable manner and based on any request (i.e. a request for a device verification value may, but need not, be based on interaction with a portable consumer device). 
     In some embodiments, the consumer may present the device verification value to a merchant as part of a financial transaction. For instance, in some embodiments, the device verification value may be stored on the consumer&#39;s mobile device, and may be transferred to the merchant through a physical interface or, preferably, through the use of short-range wireless communications (e.g. the mobile device may interact with an access device, such as a POS terminal, through a contactless interface) as part of the first financial transaction. The merchant may then generate an authorization request message for the first transaction that includes, inter alia, the device verification value received from the consumer (via the mobile device) along with other transaction related information (such as, for example, the transaction amount, a merchant identifier, information associated with the portable consumer device, etc.). The authorization request message may be sent to a payment processing network. The device verification value included in the authorization request may be compared by the payment processing network (or any other suitable entity) to a stored version of the device verification value associated with the portable consumer device. If these values match, then it is less likely that the transaction is fraudulent. 
     In some embodiments, the mobile device may further include a secured element such as a verification token that may perform some or all of the functions described herein and thereby reduce the likelihood of tampering with the hardware and/or software. Such a secured element (even if an independent component incorporated within the mobile device, or a separate competent coupled to the mobile device) may be considered a part of the mobile device as used herein. 
     Thus, in some embodiments, a financial transaction may take place in a card-present type of (e.g. “brick and mortar”) environment—i.e. the consumer may be at a merchant location, such as in the merchant&#39;s store—rather than a virtual environment, but still provide for increased security for conducting a financial transaction.

     DETAILED DESCRIPTION 
     The following disclosure may provide exemplary systems, devices, and methods for conducting a financial transaction and related activities, and in particular, methods of generating and/or obtaining a device verification value using a mobile device, and presenting that device verification value to a merchant for use in authorizing the financial transaction. 
     This application comprises subject matter that is related to U.S. App. Ser. No. 61/365,119, filed on Jul. 16, 2010, U.S. App. Ser. No. 61/178,636, filed on May 15, 2009, and U.S. application Ser. No. 12/712,148, filed on Feb. 24, 2010, each of which are herein incorporated by reference in their entirety for all purposes. 
     Before discussing specific embodiments of the invention, some descriptions of some specific terms are provided below. 
     As used herein, a “mobile device” may comprise any electronic device that may be transported and operated by a user that may also provide remote communication capabilities to a network. Examples of remote communication capabilities include using a mobile phone (wireless) network, wireless data network (e.g. 3G, 4G or similar networks), Wi-Fi, Wi-Max, or any other communication medium that may provide access to a network such as the Internet or a private network (such as those used by a payment processing network). Examples of mobile devices include mobile phones (e.g. cellular phones), PDAs, tablet computers, net books, laptop computers, personal music players, hand-held specialized readers, etc. A mobile device may comprise any suitable hardware and software for performing such functions, and may also include multiple devices or components (e.g. when a device has remote access to a network by tethering to another device—i.e. using the other device as a modem—both devices taken together may be considered a single mobile device). A mobile device may also comprise a verification token in the form of, for instance, a secured hardware or software component within the mobile device and/or one or more external components that may be coupled to the mobile device. 
     As used herein, a “portable consumer device” may be any suitable device that allows a transaction to be conducted with a merchant. 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, magnetic stripe cards, keychain devices (such as the Speedpass™ commercially available from Exxon-Mobil Corp.), etc. Other examples of portable consumer devices include cellular phones, personal digital assistants (PDAs), pagers, payment cards, security cards, access cards, smart media, transponders, 2-D barcodes, and the like. 
     As used herein, an “access device” may be any suitable device for communicating with a merchant computer and for interacting with a portable consumer device and/or mobile device. An access device may in general be located in any suitable location, such as at the same location as 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 portable consumer device and/or 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, magnetic stripe readers, etc. to interact with a portable consumer device and/or mobile device. 
     As used herein, a “verification token” may refer to a secured device or component of a device (such as a software or hardware module) that may be used to authenticate or validate a user or portable consumer device. That is, for example, the verification token may refer to a secured component (or components) of a mobile device used to determine that a user is not misrepresenting his identity and/or that he has in his possession a portable consumer device. An example of a verification token is provided in U.S. application Ser. No. 12/712,148 to Hammad, which is again hereby incorporated by reference in its entirety. In general, a verification token may take any suitable form, including an embedded software/hardware module in a mobile device or an attachment to a mobile device (such as a USB stick or other periphery component). As used herein, a verification token that is coupled to, or embedded within, a mobile device may be considered a component of the mobile device (even if the verification token could be physically separated from the mobile device). In some embodiments (e.g. where the verification token is an external component), a verification token that may be coupled to or embedded within a mobile device may utilize short-range communication (such as near-field communication including RFID or Bluetooth®) or a physical interface (such as through the use of a magnetic strip reader) to obtain information stored on a portable consumer device. As contemplated herein, this comprises the mobile device “interacting” with the portable consumer (albeit through a component that may be separately identified as the verification token). 
     As used herein, “identification information” may include any suitable information associated with an account (e.g. a payment account and/or portable consumer device associated with the account). Such information may be directly related to the account or may be derived from information related to the account. Examples of account information may include a PAN (primary account number or “account number”), user name, expiration date, CVV (card verification value), dCVV (dynamic card verification value), CVV2 (card verification value 2), CVC3 card verification values, etc. CVV2 is generally understood to be a static verification value associated with a portable payment device. CVV2 values are generally visible to a user (e.g., a consumer), whereas CVV and dCVV values are typically embedded in memory or authorization request messages and are not readily known to the user (although they are known to the issuer and payment processors). 
     As used herein, a “device verification value” may include any information related to the validation of a verification token, a user, a portable consumer device, and/or a mobile device used or associated with a financial transaction. For instance, a device verification value may be information that indicates whether a request sent from a mobile device (and/or a verification token associated with the mobile device) has been validated using any number of validity tests. Exemplary validity tests are described in detail in U.S. patent application Ser. No. 12/712,148 to Hammad entitled “Verification of Portable Consumer Devices,” which is hereby incorporated by reference in its entirety. In this manner, in some embodiments a “request for a device verification” value sent by a mobile device (and/or verification token within, or coupled to, the mobile device) may comprise a message that includes information such as “identification information” for a portable consumer device or user, as well as information associated with the mobile device (and/or verification token) such as a serial number, IP address, account number associated with the mobile device, SIM card information, etc. This information may be used by a validation entity to validate the request and return a device verification value. The device verification value may thereby comprise any information or data that is generated after a request for a verification value is validated (in some instances after a mobile device interacts with the portable device). For instance, the verification information could comprise any dynamic value (such as a dCVV2, dPAN, or other shared secret value) that is generated by a validation entity and sent to a mobile device (and/or verification token) that has interacted with an associated portable consumer device. 
     As used herein, “transaction information” may include any suitable information related to a financial transaction, such as those conducted with a merchant. This may include a transaction amount, a merchant identifier for the merchant associated with the transaction, and the volume of the transaction or accumulation of previous transactions (for instance, if there are many similar purchases, or many purchases within a short amount of time). It may also include the type of goods, the merchant location, and any other information that is related to the current transaction. 
     An “authorization request message” may be a message that includes an issuer account identifier. The issuer account identifier may be a payment card account identifier associated with a payment card. The authorization request message may request that an issuer of the payment card authorize a transaction. An authorization request message according to some embodiments may comply with ISO 8583, which is a standard for systems that exchange electronic transactions made by cardholders using payment cards. An authorization request message may comprise data elements including, in addition to the account identifier, a service code, a CVV (card verification value), and an expiration date. An authorization request message may also comprise some or all of the information associated with a transaction, such as the “account information” and/or the “transaction information,” as well as any other information that may be utilized in determining whether to authorize a transaction (e.g. a device verification value). An authorization request message may also comprise a device verification value (e.g. a dCVV2). 
     An “authorization response message” may be an issuing financial institution&#39;s electronic message reply to an authorization request, which may include 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. It may also include an authorization code, which may be a code that a credit card issuing bank returns in an electronic message to the merchant&#39;s POS equipment that indicates approval of the transaction. The code serves as proof of authorization. In some embodiments, a payment processor network may generate or forward the authorization response message to the merchant. 
     A “communications channel” may include any suitable path for communication between two or more entities. Suitable communications channels may be present directly between two entities such as a client computer and a gateway server, or may include a number of different entities. Any suitable communications protocols may be used for communications channels according to embodiments of the invention. 
     As used herein, a “server computer” is typically 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. 
     Embodiments disclosed herein may provide for systems, methods, and/or apparatuses that may utilize, for example, a form fill and mobile device payment processing for a financial transaction. The system, apparatus, and methods may be implemented using one or more computer apparatuses, mobile devices, and/or databases. Although some of the description provided below may make reference to a mobile phone, embodiments are not so limited and may utilize the features and aspects described herein in any suitable system or mobile device. Similarly, although embodiments described below may reference a server computer, embodiments are not so limited and may utilize the aspects and features described herein in any suitable system or device. 
     As noted above, methods, systems, and apparatuses that provide for increased security for financial transactions, particularly in transactions where a payment device may not be presented to a merchant (e.g. purchases over the Internet, telephone, etc.), have been developed that may reduce the occurrence of fraud and may give additional assurances that valid transactions are in fact genuine (reducing the likelihood that a valid transaction may be rejected as suspicious). Although such transactions involving remote consumers and merchants are generally more susceptible to fraudulent activity due, in part, to the inherent uncertainties that may exist in such transactions (e.g. based on the anonymity that may exist), in-person transactions may also be susceptible to such fraudulent activity as well. However, most systems and methods that have been developed for such environments may rely on the security features contained within the payment device itself, which may be presented to the merchant in conducting the transaction. Thus, these methods and systems may not provide adequate protection in situations such as, for instance, when the payment device itself is stolen or copied by a nefarious party without the knowledge of consumer. 
     Thus, while the likelihood that fraudulent transactions may occur during in-person financial transactions may not be as high as in the remote entity circumstances, it is still a possible event and does in-fact occur on a routine basis. One factor that may further increase the chance of successfully conducting such fraudulent in-person transactions is that merchants do not typically inspect such portable consumer devices offered by a consumer as payment during these in-person purchases, which may be due to the fact that Merchants do not want to negatively impact the consumer&#39;s overall shopping experience by such inquiries (or the Merchants simply do not appreciate the risk of, and/or are not liable for, a fraudulent transaction). Therefore, it may be preferred that, in some embodiments, an exemplary approach to improve security may not overly burden either the Merchant or the consumer in conducting such transactions. 
     Although not limited to use only in completing in-person transactions, some embodiments provided herein may address some of the concerns noted above regarding such fraudulent activity related to in-person transactions. 
     With reference to  FIG. 5 , an exemplary method that may be performed by several exemplary components of a system  500  that may provide for increased security in conducting a financial transaction is shown for illustration purposes. As shown in  FIG. 5 , at step S 501 , a consumer may present a portable consumer device (e.g. a payment device such as a credit card, debit card, etc.)  32  to a mobile device  36 . That is, for example, the consumer may swipe a portable consumer device  32  having a magnetic stripe using a periphery of the mobile device  36  (e.g. a physical interaction) or may use any suitable form of short range communications (e.g. near field communication, RFID, Bluetooth®, etc.). In this manner, identification information that may be stored on the portable consumer device  32  may be obtained (e.g. received) by the mobile device  36 . This information may be retained (e.g. stored) in the mobile device  36  in a secured location, for instance by using either software or hardware components (e.g. a verification token). 
     At step S 502 , the mobile device  36  may establish communications with a payment processing network  26  so as to send a request for a device verification value (e.g. a dCVV2 value). The request may comprise some or all of the identification information that the mobile device  36  received from the portable consumer device  32 . 
     In some instances, the mobile device  36  may also send information related to the mobile device  36  or components thereof (e.g. part serial numbers, mobile account information, etc) and/or information about the consumer (e.g. a username or password). The payment processing network  26  may utilize some or all of the information that was included in the request for the device verification value to validate the mobile device  36 , the consumer, and/or the portable consumer device  32 . In this manner, embodiments may provide a method for increasing the certainty that a consumer is in possession of a valid and authentic portable consumer device  32 . 
     If the request sent by the mobile device  36  is validated (which may involve passing one or more validation tests), then at step S 503  the payment processing network  26  may send back to the mobile device  36  a device verification value (e.g. dCVV2 value). The payment processing network  26  may also store the device verification value for later comparison and validation during an authorization process, or may send this value to another entity that may perform such validation (e.g. a merchant, an issuer, etc.). 
     At step S 504 , the mobile device  36  may interact with an access device at a merchant (which may interface with the merchant computer  22 ) and thereby send (e.g. pass) the device verification value received in step S 503  to the merchant computer  22 . This interaction may be performed, for example, by short range wireless communications or through a physical interaction between the mobile device  36  and an access device coupled to the merchant computer  22  (e.g. via a POS terminal). This interaction may be performed, for instance, during a first transaction between the merchant and the consumer, where the consumer may choose to use the portable consumer device  32  to pay for the transaction. That is, for instance, the consumer could provide the portable consumer device  32  to the merchant and/or interact with an access device coupled to the merchant computer  22  using the portable consumer device  32  (e.g. a physical interaction or through short range communications). The consumer may then be prompted to provide a device verification value, at which point the mobile device  36  may interact with the an access device (which may be the same access device or a different access device) coupled to the merchant computer  22  to pass the device verification value received by the mobile device  36  in step S 503 . The merchant computer  22  may then generate an authorization request message that includes transaction related data, and may form fill the request using the device verification value received form the mobile device  36 . 
     At step S 505 , the merchant computer  22  may initiate a typical authorization and clearance procedure with the payment processing network  26  using the information associated with the portable consumer device  32  and the device verification value received from the mobile device  36 . Moreover, the device verification value that the merchant computer  22  included in the authorization request message may be compared to the device verification value stored by the payment processing network  26  in step S 503 . If the two values match, then the payment processing network  26  may have further assurance that the transaction is authentic. 
     In this manner, some embodiments may provide for increased security for financial transactions (particularly those conducted in a brick and mortar environment—e.g. in-person). Moreover, by utilizing processes such as passing values between components of the system using, e.g., short range communications, some embodiments provided herein may reduce the inconvenience of the process for both the merchant and the consumer, without necessarily compromising the security provided. 
     Although steps S 502  and S 503  were described above with reference to the payment processing network  26  as the validation entity, embodiments are not so limited. For instance, in some embodiments, a separate validation entity that may be located at the payment processing network  26 , or at an entirely separate entity (that may be in communication with the payment processing network  26 ) may validate the request sent by the mobile device  36  and generate the device verification value. In addition, the communications between the mobile device  36  and the validation entity (shown as the payment processing network  26  in  FIG. 5 ) may be performed through a secured communications channel (such as an encrypted SSL session). This may provide for increased security in the system, and may increase the difficulty for the device verification value to be intercepted and/or utilized by a nefarious party. 
     Although the exemplary method described above, and with particular reference to steps S 501 -S 503 , was described as including an interaction between a mobile device and a portable consumer device to generate a request for a device verification value that may include information from the portable consumer device that may then be used by a validation entity to validate the request, embodiments are not so limited. That is, for instance, the mobile device may receive the device verification value (which, as described above, may comprise a dCCV2 value) in any suitable manner and thereby need not based on the validation process as described above. That is, by way of example only, the consumer may register in advance with an issuer or payment processing network, and may send a request for a device verification value to either of these entities (e.g. by utilizing a username and password system, challenge—response system, etc). For instance, The consumer could enter his credentials and receive from the issuer or payment processing network the device verification value if the credentials are correct and/or validated. In some embodiments, the mobile device could be registered in advance, and thereby if the mobile device sends a request for a device verification value, the receiving entity (such as the issuer or the payment processing network) may return a device verification value for a portable consumer device associated with the mobile device. In some embodiments, an application (or other software or hardware module) may be installed on the mobile device and may be configured to function only with regard to the registered device, which may add security to the process. The above are just a few examples provided for illustration purposes; however, any suitable method of receiving a device verification value on a mobile device may be utilized.

     Described below are further exemplary embodiments of methods, systems, and apparatuses that may comprise form fill and mobile device payment processing. The embodiments described herein are for illustration purposes only and are not thereby intended to be limiting. After reading this disclosure, it may be apparent to a person of ordinary skill that various components and features as described below may be combined or omitted in certain embodiments, while still practicing the principles described herein. 
     In some embodiments, a first server computer may be provided. The first server computer may comprise a processor and a computer readable medium coupled to the processor. The computer readable medium may include code executable by the processor for implementing a method. The method may include the step of electronically receiving an authorization request message that includes a first device verification value from a merchant for a first transaction, where the first device verification value may have been received by the merchant from a mobile device based on an interaction between the mobile device and an access device. As was described above, the interaction between the mobile device and the access device may have comprised a short-range wireless communication or a physical interaction (such as a magnetic swipe, USB interface, etc.). The mobile device may have received the first device verification value based on a first request. The method may further include the step of determining by a data processor if the first device verification value corresponds to a stored device verification value. 
     As was noted above, the first request may be sent by the mobile device to any suitable entity, and may include any relevant information. For example, the first request may include information about a consumer (such as a username and password), information about the mobile device (such as SIM card information, application specific information, serial number, etc.), and/or information corresponding to a portable consumer device (e.g. account number, expiration date, etc.). In some embodiments, the first request may be initiated based on a request by a user (e.g. a user may initiate the first request) and/or may the request may be based on a interaction between a mobile device and a portable consumer device (e.g. the mobile device may automatically generate a request after such an interaction). However, in some embodiments, so long as the device verification value may be received by the mobile device, the form of the request, the information that it may contain, and/or the entity that the request is sent to may not affect the functioning of the method and system (or components therein). 
     In general, the term “based on interaction,” as used herein may include any suitable method of facilitating the transfer of information stored on one device to another (e.g. from the portable consumer device—such as a credit card—to the mobile device (or a component thereof) and/or from the mobile device to an access device—such as an access device). 
     For example, in some embodiments, the merchant may receive the stored device verification value from the mobile device based on an interaction between the mobile device and an access device. That is, for instance, in some embodiments after the first device verification value is received by the mobile device, the mobile device (which may, for instance, comprise a contactless interface or other short-range communication capability) may establish communications with the merchant through an access device (where an access device is described below). In this manner, embodiments may provide a secure way to send the device verification value to the merchant from the mobile device for use in an authentication request message. Moreover, in some embodiments where the mobile device comprises a secure component (e.g. hardware or software corresponding to a verification token), the interaction with the merchant&#39;s access device may be the most efficient manner of retrieving the device verification value from the mobile device, which also may prevent fraudulent activity such as, for instance, if a unscrupulous party were to acquire the device verification value (which may be the case if it is unsecured and/or presented to a user) and attempt to authenticate a transaction. However, embodiments are not so limited, and in some instances, the device verification value may be presented to a consumer (e.g. graphically), and the consumer may then pass that information to the merchant for inclusion in the authentication request. 
     The use of the term “stored” with regards to the “stored device verification value” does not necessarily mean that it is different than the “first” device verification value, but is simply used to differentiate the device verification value that is generated, received, and/or stored by the sever computer (or other validation entity) in an initial validation process (examples of which are described below), with the device verification value that is received by the server computer in the authorization request message. For example, when a transaction is valid, the stored device verification value may correspond to the first device verification value that was first received by the mobile device based on an interaction with the portable consumer device, and which was then sent from the mobile device to the merchant. That is, for instance, the server computer may retrieve the stored verification value and compare this to the received first verification value. If there is a correspondence (e.g. if the values match), the server computer has an additional indication that the transaction may be valid. If the values do not match, then this may indicate that there is an increased risk that the transaction is fraudulent. 
     In some embodiments, and as was discussed above, the interaction between the mobile device and the access device may comprise short-range communication. As used herein, “short range communication” or “short range wireless communication” may comprise any method of providing short-range communications capability, such as RFID, Bluetooth™, infra-red, or other data transfer capability that can be used to exchange data between a portable consumer device, an access device, and/or an emulation device. In some embodiments, short range communications may be in conformance with a standardized protocol or data transfer mechanism (e.g., ISO 14443/NFC). Short range communication typically comprises communications at a range of less than 5 meters. In some embodiments, it may be preferable to limit the range of short range communications (such as to a range of less than 1 meter, less than 10 centimeters, or less than 2.54 centimeters) for security, technical, and/or practical considerations. For instance, it may not be desirable for a POS terminal to communicate with every portable consumer device that is within a 10 meter radius because those two devices may not be involved in a transaction, or it may interfere with a current transaction involving different financial transaction devices. 
     In general, the use of short range communications may be preferred in some embodiments because it permits devices that otherwise may have no immediate manner to communicate (e.g. the devices may not have corresponding physical interfaces) to do so—and beneficially do not require physical contact, which may avoid damage. Moreover, this may provide for quick communication, with minimal effort on the part of the entities involved in the transaction. The use of short range communications may be used when the merchant and the consumer are in close geographic proximity, such as when the consumer is at the merchant&#39;s place of business. In some embodiments, the access device may include a point-of-sale terminal (POS). 
     The term “associated with a first transaction” may generally refer to when the portable consumer device is presented or selected by a consumer as a payment method for a transaction. For instance, the consumer may present the portable consumer device to the merchant, who may then utilize the card to complete the transaction (e.g. as a typical credit card transaction). In some embodiments, the information associated with the portable consumer device may be received and stored on the mobile device (e.g. based on the interaction that may initiate the request for the device verification value), such that only the mobile device may need to be presented to the merchant (e.g. a POS terminal) to complete the transaction. Such embodiments may be preferred in some instances, because, for example, the portable consumer device need only be interacted with once, and the relevant information corresponding to both the portable consumer device and the device verification value may be sent to the merchant via a single interaction. 
     In some embodiments, in the first server computer as described above, the method may further include the step of electronically receiving the first request for the first device verification value from the mobile device, where the first request comprises identification information for the portable consumer device. The method may further include the steps of performing by a data processor at least one validation test pertaining to the first request and electronically sending the first device verification value to the mobile device if the at least one validation test is passed. 
     For instance, in some embodiments, the user may present (e.g. move into close proximity or physically contact) the portable consumer device (e.g. a payment card) to a mobile device (e.g. a mobile phone). The mobile device may comprise a short-range communication interface (e.g. a contactless interface, Bluetooth®, etc.) or other suitable interface (such as a magnetic stripe reader), for which the portable consumer device may comprise a compatible interface. In this manner, the information stored on the payment device (which may include information hidden from a user so as to prevent its misappropriation) may be received and utilized by the mobile device in generating a request that may be sent to the server computer, such that the server may validate the consumer and/or a transaction associated with the portable consumer device. In this regard, and as detailed below, the mobile phone may have one or more secured components (which may, for example, comprise a verification token), such that the information obtained from the portable consumer device (e.g. payment card) not only remains secure, but that any entity that receives such information from the mobile device may have further assurance that the payment card was actually presented to the mobile device. For embodiments comprising a verification token, the verification token may also have stored thereon instructions for operations to perform the validation process, including, for example, the location of the server computer, the format of the request to generate, etc. In some embodiments, this may be stored in a non-secure application (or hardware) on the mobile device, or within the portable consumer device. 
     As noted above, the server computer (an example of which is described in detail with reference to  FIG. 2 ) may receive a “request” from the mobile phone for a device verification value. The request may be in any suitable form, including an electronic message that comprises one or more packets of data. The request may be received by the server computer and may comprise any suitable information related to, for instance, the portable consumer device, the mobile device, the user, or even transaction information (to the extent that any may exist at the time). As described below, this information may be used to validate the request, and thereby provide additional assurances that the consumer (or the portable consumer device) is valid. Moreover, the request may be sent via a secured channel and/or over any suitable network, including the Internet or over a private network. 
     Thus, as was noted above, a device verification value (such as was described above), may provide information that may be subsequently used to authenticate the consumer, mobile device, and/or a financial transaction. That is, for instance, a consumer that possesses a valid device verification value (or for which a valid device verification value may be presented during the completion of a financial transaction that indicates that the consumer and/or mobile device has been validated) may provide additional assurances that the consumer is the rightful holder of the portable consumer device and the financial transaction is not fraudulent. Thus, prior to providing such information, the server computer may conduct one or more validation tests. Exemplary validation tests for use with a “verification token” are described, for example, in U.S. application Ser. No. 12,780,657 filed on May 14, 2010 to Hammad, the entire disclosure of which is hereby incorporated by reference. Many of the principles and validation tests described therein may be equally applicable to validation of the request sent from a mobile device as described herein (particularly if the device comprises a secured component corresponding to a verification token). For example, the request may include identification information that identifies the payment account associated with a portable consumer device as well as information that corresponds to the mobile device (e.g. serial number, wireless account information, SIM card information, etc.). In some embodiments, the server computer may comprise (or be in communication with) a database that associates the payment account information with a particular mobile device, and thus if such information is included by the mobile device in the request, the server computer may be more assured that this is a valid request because the consumer not only is in possession of the portable consumer device, but also a mobile device associated with the payment device. 
     Some embodiments of systems and methods that may utilize a server computer to validate a request received from a mobile device (e.g. based on an interaction with a portable consumer device) may be utilized, for instance, in a “brick and mortar” environment, rather than (or in addition to) in a remote transaction environment (e.g. e-commerce). For example, the mobile device may be used by the consumer in different locations (such as at different merchant locations), and may provide relatively quick validation and response to a request sent by the mobile device, with minimal effort on the part of both the merchant and the consumer. The device verification value received from the server may then be provided as part of a subsequent transaction (e.g. in an authentication request message), and may be used by an authorization entity to determine whether to approve a transaction, as described in detail herein. 
     In some embodiments, in the first server computer as described above, the method may further include the step of electronically storing the first device verification value by the server computer. That is, for instance, if the first request for a first device verification value is validated such that a device verification value is sent to the requesting mobile device, the server computer (e.g. the validation entity) may also store the first device verification value (or send the first device verification value to an entity or a database that may store the device verification value). The stored first device verification value may be later used in a comparison to determine if, in a subsequent transaction, the portable consumer device and/or the consumer is authentic. That is, for instance, the device verification value may function similar to a shared secret, and the server computer (or other validation or authentication entity) may use this shared secret value to authenticate a transaction involving the portable consumer device, as described above. 
     In some embodiments, in the first server computer as described above, the method may further include the steps of: generating an authorization response message based at least in part on the determination by the data processor as to whether the first device verification value is the same as the stored device verification value, and electronically sending the authorization response message to the merchant. That is, as noted above, the server computer (or other authorization entity) may compare the received device verification value with the stored device verification value (generated during the validation of the first request from the mobile device) as further criteria in determining whether to authorize a transaction comprising the portable consumer device. In some embodiments, if the first device verification value and the stored device verification value do not correspond (i.e. match), the transaction may be declined. In some embodiments, if the first device verification value and the stored device verification value do no correspond, then this may be considered as part of several other factors (such as the merchant identifier, volume of transactions, transaction histories, etc.) to determine a risk score associated with a transaction. An example of risk score determinations is provided in U.S. application Ser. No. 13/184,080 filed Jul. 15, 2011 to Hammad entitled “Token Validation for Advanced Authorization,” which is hereby incorporated by reference in its entirety. 
     In some embodiments, in the first server computer as described above the first request may further include information associated with the mobile device. In some embodiments, the step of validating the received first request may be based at least in part on the information associated with the mobile device. As was described above, the “information associated with the mobile device” may comprise any information that may be used to identify the mobile device (and/or an associated verification token), including, by way of example only, SIM card information, IP address information, hardware specific information, token serial number, phone number, wireless account number, etc.. 
     In some embodiments, the mobile device may include a verification token. As was described above, a “verification token” may comprise a separate component coupled to the mobile device, or it may comprise a hardware or software module disposed within the mobile device. However, in general, a verification token may simply refer to a secured component of the mobile device that may, or may not, comprise instructions for initiating and/or completing a request a device verification value. In some embodiments, the mobile device may be anyone of: a mobile phone, a PDA, a tablet computer, a net book, a laptop computer, a personal music player, or a hand-held specialized reader. 
     In some embodiments, the first device verification value may include anyone of a: dynamic card verification value 2 (dCVV2), a dynamic primary account number (dPAN), and/or a shared secret value. As was described above, the device verification value may comprise any data that may be used by the mobile device and/or the server computer (or other authorization entity) to determine if a portable consumer device (or a mobile device or consumer associated with the portable consumer device) involved in a transaction was previously validated. In this regard, it may be preferred that the device verification value (regardless of characterization) remain a secret known only to the authentication entity and the mobile device, such that when the device verification value is subsequently received by the server computer, this may be an indication that the transaction is authentic. 
     In some embodiments, in the first server computer as described above, the method may further include the step of establishing a communications session with the mobile device. In some embodiments, the secured communication channel may be secured by one or more encryption keys. In some embodiments, the request for the device verification value may be received through the communications session. In some embodiments, the device verification value may be provided through the communications channel. That is, it may be preferred that the mobile device and the server computer communicate over a secure communications session (e.g. a secure channel) so that when the server computer sends the device verification value, another party may not be capable of intercepting that value and then using the device verification value to complete a transaction. The secured communication session may be established in any suitable manner. For instance, the sever computer could register the mobile device (and its IP address or related information) for a session. A session key may then be established upon mutual authentication to support the communications for that session between the mobile device and the host. The data exchanged between the token and the server computer (e.g. the backend host) may be encrypted and tunneled through an SSL session. The session could stay alive or be terminated or restarted at any time. 
     In some embodiments, a first method may be provided. The first method may be performed, in whole or in part, by one or more computers (e.g. server computers) and/or one or more software/hardware components within a computer. The first method may include the steps of electronically receiving an authorization request message comprising a first device verification value from a merchant for a first transaction and determining by a data processor if the first device verification value corresponds to a stored device verification value. In some embodiments, the first device verification value may have been received by the merchant from a mobile device based on an interaction between the mobile device and an access device, where the interaction between the mobile device and the access device may comprise, by way of example, short-range wireless communication or a physical interaction. The mobile device may have received the first verification value based on a first request. In some embodiments, the first request was based on an interaction between the mobile device and a portable consumer device. In some embodiments, the first request was based on information provided by a consumer (where the information may have been entered in advance of the generation of the first request—e.g. it may have been stored on the mobile device—or the information may have been entered concurrently with the generation of the first request—e.g. entering in a username and password, challenge response, etc.). 
     As was described above, the device verification value may be stored (e.g. by an authentication entity) and used as an indication as to whether a mobile device and/or portable consumer device used as part of a transaction with a merchant is authentic. Moreover, the authorization request may be initiated by, for instance, an interaction between a consumer&#39;s mobile device (which may have stored thereon the first device verification value) and a merchant&#39;s access device. This may be an efficient manner of sending a previously received device verification value from the mobile device to the merchant to authorize a transaction (i.e. to include the device verification value in an authorization request). 
     In some embodiments, the first method as described may further include the steps of electronically receiving the first request for the first device verification value from the mobile device, where the first request may comprise identification information for the portable consumer device. The first method may further include the steps of performing by a data processor at least one validation test pertaining to the first request, electronically sending the first device verification value to the mobile device if the at least one validation test is passed, and electronically storing the first device verification value. As noted above, a mobile device may establish communications with a validation entity (such as a server computer or IP gateway), and may then request a device verification value from such an entity. The validation entity may use any information received from the mobile device along with, for instance, previous data stored about the portable consumer device and/or mobile device such as: black lists (devices associated with fraudulent activity), white lists (devices not associated with fraudulent activity), associations between portable devices and mobile devices (e.g. registration of information), etc. so as to validate the request. Although not limited thereto, the use of a mobile device may provide for embodiments that may make “brick and mortar” transactions (e.g. where the consumer may be located at the merchant location) more secure, while not substantially increasing the burden on either party. 
     In some embodiments, the first method as described above may further include the steps of generating an authorization response message based at least in part on the determination by the data processor as to whether the first device verification value corresponds to the stored device verification value and electronically sending the authorization response message to the merchant. In some embodiments, in the first method as described above, the first request may include information associated with the mobile device; and the at least one validation test pertaining to the first request may be based at least in part on the information associated with the mobile device. 
     In some embodiments, a mobile device may be provided. The mobile device may comprise a processor, and a computer readable medium coupled to the processor that may include code executable by the processor for implementing a method. The method may include the steps of electronically sending a first request for a first device verification value to a server computer, electronically receiving from the server computer the first device verification value The use of a mobile device in some embodiments may provide for increased mobility and flexibility, and may also provide for validation of a portable consumer device “on the fly” while, for instance, a consumer is located at a merchant. In some embodiments, the method may further include the steps of receiving identification information stored on a portable consumer device based on an interaction between the portable consumer device and the mobile device. In some embodiments, the first request may include at least some of the identification information stored on the portable consumer device. In some embodiments, the device verification value is received from the server computer only if the first request is validated. In some embodiment, the validation of the first request may be based at least in part on the identification information. 
     Moreover, utilizing a mobile device may permit increased security during traditional transactions that otherwise may rely almost entirely on the security features corresponding to the portable consumer device itself. For example, a mobile device may be linked to a wireless phone account or mobile phone serial number (e.g. in a database). The mobile device may send this information along with the request for the first device verification value to a validation entity (e.g. server computer and/or a gateway computer). The server computer (e.g. validation entity) may receive this information and determine if the received information matches any records stored therein. If it does not, then the mobile device may not receive the device verification value from the server computer. Thus, if for example a nefarious party steals a consumer&#39;s credit card, and then attempts to receive a dynamic verification value for the credit card to be used in a transaction, even though the nefarious party is in physical possession of the credit card (which previously may have been sufficient to complete the fraudulent transaction), he may not receive the device verification value and thereby such a transaction may be later denied. This example is provided for illustration purposes only, and as was noted above, there may be any number of suitable ways that may be used to validate the first request. 
     In some embodiments, in the mobile device as described above, the method may further include the step of: electronically sending the first device verification value to a merchant associated with a first transaction based on an interaction between the mobile device and an access device. In some embodiments, the interaction between the mobile device and the access device may include short-range communication. In some embodiments, the access device may be located at the merchant associated with the first transaction. As was noted above, embodiments may be utilized by consumers when located at a merchant, and thereby once the device verification value is received, the inventors have found that a relatively efficient and secure way of passing this information between the mobile device and the merchant may be to use a short-range communication interface (particularly in embodiments where the device verification value is stored in a secure hardware or software component of the mobile device). For example, mobile devices (such as mobile phones) may be constructed with short-range communications capability, and thereby provide increase functionality and security without an increased burden on the consumer. 
     In some embodiments, in the mobile device as described above that includes a processor and a computer readable medium comprising code that may be executable by the processor for performing of the above methods, the first device verification value sent to the merchant by the mobile phone may be included by the merchant in an authorization request message that may be sent to a payment processing network. By including the device verification value in the authentication request, in some embodiments, the authorization entity (which may be located at a payment processing network) may receive the device verification value and may compare this value to a stored value that corresponds to the device verification value previously sent to the mobile device thereby increasing the security of such transactions. 
     In some embodiments, in the mobile device as described may include a verification token. As noted above, the verification token of a mobile device may refer to a secure hardware of software component of the mobile device. In some embodiments, the verification token may be an external component that may be coupled/decoupled to the mobile device. The verification token, in some embodiments, may include its own short-range communications interface. It may be preferred in some embodiments to utilize a verification token that is a separate component from the mobile device that may be coupled and decoupled to a mobile device such that a consumer could use the verification token with multiple mobile devices or fixed devices (i.e. it would not require the consumer to purchase multiple verification tokens). Moreover, this may facilitate, in some embodiments, the linking of a portable consumer device with a particular hardware component, and thereby provide more security. For example, if the portable consumer device is used with a verification token or mobile device that is not the verification token that it is usually associated with, it may be likely that the transaction is fraudulent). 
     In some embodiments, in the mobile device as described above that includes a processor and a computer readable medium comprising code that may be executable by the processor for performing the methods described above, the method may further include the step of: sending to the server computer at least one of: a token serial number, a phone number, an IP address, a mobile phone serial number, a wireless account number, a SIM card information. This information that may be associated with the mobile device (and/or a verification token comprised within the mobile device) may be utilized in some embodiments by a validation entity so as to validate the request for the device verification value. For instance, the information associated with the mobile device may be stored at the server computer and associated with a portable consumer device prior to the receipt of a request from a mobile device. In some embodiments, the information (which may be unique to a mobile device) may be included on a white list or a black list (e.g. of known fraudulent entities). However, as described above, this information may be used in any suitable manner to validate the request and confirm the authenticity of the portable consumer device, the consumer, and the mobile device. 
     In some embodiments, in the mobile device as described above that includes a processor and a computer readable medium comprising code that may be executable by the processor for performing the methods described above, the method may further include the steps of storing the first device verification value, and electronically sending the first device verification value to a merchant associated with a second transaction based on an interaction between the mobile device and an access device. That is, for instance, in some embodiments, a single device verification value may be used to authenticate multiple transactions. This may reduce the number of operations that the payment processing system (or other validation entity) needs to perform. For example, there could be a fixed number of transactions for which a device verification value may be used for prior to a new verification needing to be generated, or the device verification value may be valid for a fixed period of time. Embodiments may thereby provide for increased security associated with the use of a device verification value, but reduce inconvenience to the consumer and/or data traffic on a network. 
     In some embodiments, a first method may be provided. The first method may be performed, in whole or in part, by one or more computers (e.g. server computers and/or mobile devices) and/or one or more software/hardware components within a computer. The first method may include the steps of: electronically sending, by a mobile device, a first request for a first device verification value to a server computer and electronically receiving, at the mobile device, the first device verification value from the server computer. 
     In some embodiments, the first method as described above includes the step of receiving, at the mobile device, identification information stored on a portable consumer device based on an interaction between the portable consumer device and the mobile device. In some embodiments, the first request as described above may include at least some of the identification information stored on the portable consumer device. In some embodiments, the device verification value is revived if the first request is validated based at least in part on the identification information. 
     In some embodiments, the first method as described may further include the steps of initiating a first transaction with a first merchant, interacting with an access device for the merchant associated with the first transaction using the mobile device, and electronically sending, via the mobile device, the first device verification value to the merchant associated with the first transaction based on the interaction between the mobile device and an access device. In some embodiments, the method may further include the steps of initiating a first transaction with the first merchant, and interacting with the access device for the merchant associated with the first transaction using the mobile device. In some embodiments, the interaction with the access device may comprise short-range wireless communications and/or a physical interaction. In some embodiments, the first merchant may include the first device verification value in an authorization request message associated with the first transaction. 
     In some embodiments, in the first method as described above, the first method may further include the step of presenting the portable consumer device to the first merchant to pay for the first transaction. In some embodiments, the first method may include presenting the mobile device to the first merchant to pay for the first transaction. 
     In some embodiments, another method may be provided that comprises the steps of electronically sending by a mobile device a first request for first information to a server computer, wherein the first request is generated based on an interaction between the mobile device and a portable consumer device; electronically receiving at the mobile device the first information from the server computer; and electronically sending by the mobile device the first information to a merchant associated with a first transaction based on an interaction between the mobile device and an access device located at the merchant. 
     As used in this connect, the “first information” may refer to any information that may be used by the consumer, merchant, and/or the mobile device to for use in completing or authenticating the transaction. Some examples of first information could include a verification value, a dynamic verification value, an account number, an account balance, an authorization message, an IP address, a session key, an account identifier, an expiration date, previous transaction information, or any other relevant category of data. The information may be used by the merchant and/or payment processing network in any suitable manner. For example, when the first information comprises a verification value, the merchant computer may include this information in an authorization request message to complete the first transaction (e.g. for the payment processing network to verify that the transaction is authenticated). When the first information comprises an account balance, the merchant computer may use this information to determine whether the consumer has sufficient funds to complete the transaction or if an alternative payment method may be required. When the first information comprises an account number, the merchant computer may use the account number to identify an approiate payment method to be used to complete the transaction (which may also be used by the payment processing network when authorizing the transaction). When the information comprises an IP address, the merchant computer may contact a server computer or router at the IP address and send or receive relevant information based on this connection (such as when the IP address corresponds to an IP Gateway computer that may authorize or validate transactions). It should be appreciated that these are just a few examples of the types of information that may be provided to the mobile device (and potential uses of that information). 
     An example of a process that includes the method as described above is provided below for illustration purposes. A consumer may use his mobile device (e.g. a mobile phone) to interact with a portable consumer device (e.g. a payment card such as a credit card, debit card, etc.) via a contactless interface (e.g. near filed communication) or a physical interface (e.g. swipe). The mobile device may then generate a request for information based on this interaction, which is then sent to a server computer (e.g. at a payment processing network). The request may, but need not, include information received from the portable consumer device such as an account number, a security code, expiration data, consumer name, account number, etc. Some or all of this information could also be stored on the mobile device (such as in a mobile application) rather than being received from the portable consumer device. The request from the mobile device may be sent by any suitable communication channel to the server computer, such as via a wireless network, data network, or wireless LAN network. The server computer may receive the request from the mobile device and provide the first information to the mobile device via the same channel or a different communication channel. 
     After receiving the first information from the server computer, the mobile device may then interact with an access device located at a merchant. This interaction could comprise a physical interaction, but preferably comprises a short range wireless communication (such as near filed communication, IR, Bluetooth®, etc). The first information may then be sent by (i.e. passed from) the mobile phone to the access device based on this interaction (and preferably though the same communication channel as the interaction). In this manner, the first information that was sent to the mobile device from the server computer based on an interaction between the mobile device and the portable consumer device may then be sent (i.e. passed) to the merchant. The merchant may then include the first information in an authentication request message, or may otherwise use the information to complete the transaction (such as by using the first information to approve the first transaction, identify a location or entity to send an authorization request to, or to authenticate the consumer or the first transaction). 
     In some instances, to complete the first transaction, the consumer may, but need not, present the portable consumer device to the merchant (either before or after the first information is sent to the merchant by the mobile device). That is, for example, the consumer may still present the portable consumer device to the merchant to pay for the first transaction, and the first information may then be used as further verification of the authenticity of the transaction (or for any other suitable purpose). However, in some embodiments, the consumer need only present the mobile device to the merchant to complete the transaction (i.e. to provide sufficient information to pay for the transaction). The first information (which is sent from the mobile device to merchant) could thereby be sufficient to complete the first transaction, or could be used to supplement payment information stored on the mobile device. 
     In some embodiments, the server computer could perform one or more validation tests on the first request that is sent by the mobile device, but this is not required. For instance, the mobile device may have a secured application or hardware component that insures that the request is authenticated and therefore the server computer need not perform additional validations tests on the request. The server computer may also store the first information that is sent to the mobile device for later authentication of the first transaction (e.g. to approve an authentication request received by the merchant regarding a first transaction involving the portable consumer device). 
     I. Exemplary Systems 
     A system according to an embodiment of the invention is shown in  FIG. 1 . The system  20  may include a plurality of merchants, access devices, portable devices, acquirers, and issuers. For example, the system  20  may include a merchant computer  22  associated with a merchant, an acquirer computer  24  associated with an acquirer, and an issuer computer  28  associated with an issuer. A payment processing network  26  may be disposed between the acquirer computer  24  and the issuer computer  28 . Further, the merchant computer  22 , the acquirer computer  24 , the payment processing network  26 , and the issuer computer  28  may all be in operative communication with each other. The merchant computer  22  may be coupled to an access device (such that information may be received by the access device and communicated to the merchant computer) or, in some embodiments, the access device may comprise a component of the merchant computer  22 . 
     A mobile device  36  may communicate with the merchant computer  22  via short-range communications  72  (such as, for instance, a contactless interface) with an access device. A verification token  34  may be associated with the mobile device  36  that is used by a user  30 . The verification token  34  may enable the mobile device  36  to form a first secure communications channel  38  (an example of a first channel) to an Internet Protocol Gateway (IPG)  27 , which may be in operative communication with the payment processing network  26 . Although the IPG  27  is shown as being a separate entity in  FIG. 1 , the IPG  27  could be incorporated into the payment processing network  26 , or could be omitted. In the latter situation, the first secure communications channel  38  could directly connect the payment processing network  26  and the mobile device  36 . In addition, the verification token  34  is shown as connected with to the portable consumer device  32  and mobile device  36  by dotted lines in  FIG. 1  so as to indicate that some embodiments may not include a verification token  34  and/or the verification token  34  may be included within the mobile device  36 . 
     The mobile device  36  may be in any suitable form, such as those described above. In some embodiments, the mobile device  36  may comprise a processor, and a computer readable medium coupled to the processor. The computer readable medium may comprise code, executable by the processor, for implementing a method comprising: receiving identification information from a portable consumer device  32  that interacts with the mobile device  36  (and/or verification token  34 ), wherein the portable consumer device  32  may comprise, for example, a chip storing the account information; establishing a secure communications channel with a remote server computer (e.g. IPG  27  and/or payment processing network  26 ); and sending the account information associated with the portable consumer device  32  (along with information associated with the mobile device  36 ) to the server computer as part of a request for a device verification value, where the server computer thereafter may validate the request for a device verification value (and/or may validate the mobile device  36 , verification token  34 , and/or portable consumer device  32 ). In some embodiments, some or all of the steps described above may also be performed by the verification token  34 , which as noted above may be incorporated into, or coupled to, the mobile device  36  (and thereby as used herein, may be considered as a part of the mobile device  36 ). The mobile device  36  may also be programmed or configured to interact with an access device coupled to a merchant computer  22 , and thereby send the received device verification value to the merchant computer  22  via the access device. 
     The payment processing network  26  may reside between the acquirer computer  24  and an issuer computer  28 . The path that includes the merchant computer  22 , the acquirer computer  24 , and the payment processing network  26 , may form at least part of a second communications channel. 
     As used herein, an “issuer” is typically a business entity (e.g., a bank) that maintains financial accounts for the user  30  and often issues a portable consumer device  32  such as a credit or debit card to the user  30 . A “merchant” is typically an entity that engages in transactions and can sell goods or services. An “acquirer” is typically a business entity (e.g., a commercial bank) that has a business relationship with a particular merchant or other entity. Some entities can perform both issuer and acquirer functions. Some embodiments may encompass such single entity issuer-acquirers. 
     The portable consumer device  32  may be in any suitable form. In some embodiments, portable consumer devices are transportable by nature. As was noted above, suitable portable 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 devices include cellular phones, personal digital assistants (PDAs), pagers, payment cards, security cards, access cards, smart media, transponders, and the like. The portable devices can also be debit devices (e.g., a debit card), credit devices (e.g., a credit card), or stored value devices (e.g., a stored value card). 
     The payment processing network  26  may include data processing subsystems, networks, and operations used to support and deliver authorization services, exception file services, and clearing and settlement services. For example, the payment processing network  26  may comprise a server computer, coupled to a network interface, and a database of information. An exemplary payment processing network may include VisaNet™. Payment processing networks such as VisaNet™ are able to process credit card transactions, debit card transactions, 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. The payment processing network  26  may use any suitable wired or wireless network, including the Internet. 
     Although many of the data processing functions and features of some embodiments may be present in the payment processing network  26  (and a server computer therein), it should be understood that such functions and features could be present in other components such as the issuer computer  28 , and need not be present in the payment processing network  26 , or server computer therein. 
     With reference to  FIG. 2 , an exemplary server computer  230  in payment processing network  26  is shown. It should be noted that for illustration purposes, many components related to various functionality were included in the exemplary server computer  230  in payment processing network  26 . However, in some embodiments, one or more of these functions may be located at a different entity within the system  20 , and/or one or more components may be disposed within one or more computers and/or database. 
       FIG. 2  provides a more detailed illustration of an exemplary embodiment of a system for implementing some of the functionality for validating a request for a device verification value and/or authorizing a transaction associated with the request for the device verification value. Specifically, an exemplary server computer  230  that may perform functions in accordance with aspects described above is provided. This exemplary server computer  230  may, for example through the use of software instructions and/or hardware configurations, perform some of the relevant functions and steps described at least with reference to  FIGS. 3 and 5 . It should be noted that although  FIG. 2  illustrates all of the modules located on a single device, the disclosure is not meant to be so limited. A system for implementing functionality related to, for example, validating a request for a device verification value received from a mobile device (and/or authorizing a financial transaction associated with the device verification value) may have additional components or less then all of these components. 
     Additionally, some modules could be located on other devices such as a remote server or other local devices that are functionally connected to the server computer component(s). 
     The communication module  201  may be configured or programmed to receive and transmit information through the network to any of the entities shown in  FIG. 1 . The received information may comprise, for instance, identification information, mobile device information (and/or verification token information, etc.) and/or any other information that the payment processing network  26  may utilize in determining whether a request for a device verification value is valid. In some embodiments, the received information may also comprise whether an authorization entity (e.g. an issuer or merchant) approved or declined a transaction involving a mobile device  36  and/or portable consumer device  32 . The communication module  201  may transmit any received information to an appropriate module, including the identification information module  202 , mobile device/token information module  203 , validation module  204 , device verification value generation module  205 , update module  206 , authorization module  207 , and/or risk score generation module  208 . 
     The communication module  201  may also be configured or programmed to receive from the authorization module  207  and/or the risk score generation module  208  an authorization response message or a risk score associated with a transaction, respectively, and to transmit the authorization response message or the risk score to an appropriate entity. In some embodiments, the received and transmitted information may be in the form of an authorization request message or authorization response message. In some embodiments, the communication module  201  may also request information that may be stored at the payment processing network  26  and/or an issuer computer  28 . Such information may comprise, for instance, information associated with an account, a portable consumer device  32 , or a mobile device  36  (and/or verification token  34 ) used in the transaction (such as PANs, CVVs, past transaction information, etc). This information may then be utilized by the authorization module  207  and or risk score generation module  208  in determining whether to authorize a transaction and/or generate the risk score associated with the transaction. 
     The identification information module  202  may be programmed or configured to perform some or all of the functions associated with utilizing the identification information received in a request for a device verification value. For instance, the identification information module  202  may be programmed or configured to identify the identification information in the request and to send this information to the validation module  204 . The identification information module  202  may also send data related to the identification information to the update module  206 , which may then update the validation database  210  with this information. In some embodiments, the identification information module  202  may also receive from the validation database  210  additional information associated with the received identification information, including, for instance, whether such information has been associated with fraudulent transactions in the past. The identification information module  202  may then send this information to the validation module  204  for use in validating the request. 
     The mobile device/token information module  203  may be programmed or configured to perform some or all of the functions associated with utilizing the mobile device (and/or verification token) information received in a request for a device verification value. For instance, the mobile device/token information module  203  may be programmed or configured to identify the mobile device (and/or token) information in the request (which may include, for instance, serial numbers, mobile account information, etc.) and to send this information to the validation module  204 . The mobile device/token information module  203  may also send data related to the mobile device (and/or verification token) to the update module  206 , which may then update the validation database  210  with this information. In some embodiments, the mobile device/token information module  203  may also receive from the validation database  210  additional information associated with the received mobile device information, including, for instance, whether such information has been associated with fraudulent transactions in the past. The mobile device/token information module  203  may then send this information to the validation module  204  for use in validating the request. 
     The validation module  204  may be configured or programmed to perform some or all the functions associated with utilizing the received identification information and/or mobile device information to validate the request for a dynamic verification value. This may include receiving appropriate information from the communication module  201 , identification information module  202 , and mobile device/token information module  203  and performing one or more validation tests using this information. Exemplary validation tests and methods for validating a request for a device verification value, as noted above, are described in detail in U.S. patent application Ser. No. 12/780,657 to Hammad entitled “Verification of Portable Consumer Devices,” which is hereby incorporated by reference in its entirety. In this regard, the validation module  204  may also communicate with one or more databases (including validation database  210 ) to retrieve information stored therein to perform any of the validation tests, as required. For example, information about previous fraudulent activity that may be associated with a mobile device  36  or a portable consumer device  32  may be used in determining whether to validate the received request for a device verification value. In some embodiments, this information may be received from the identification information  202  and/or mobile device/token information  203  modules. 
     In addition, the validation module  204  may also utilize the received identification information and mobile device information in a comparison with similar information stored in validation database  210 . That is, for instance, in some embodiments, a consumer may register a portable consumer device  32  with a mobile device  36  in advance (e.g. the mobile device  36  may be associated with a portable consumer device  32  or a payment account), such that when the two devices are used together, the validation entity (in this exemplary embodiment, the payment processing network  26 ) may have further assurance that the request is valid. However, embodiments are not so limited, and any suitable validation test may be used. 
     The device verification value generation module  205  may be configured or programmed to perform some or all the functions associated with generating a device verification value, provided that the received request is validated by the validation module  204 . For example, the device verification value generation module  205  may be programmed or configured to receive an indication from the validation module  204  that the request has been validated, and may then use any suitable process for generating a variable datum or other data that may be used as a device verification value (e.g. a dCVV2 value). The device verification value generation module  205  may also send the device verification value to the communications module  201  to be included in a response message to the mobile device  36 . Moreover, the device verification value generation module  205  may also provide the device verification value to a database (e.g. located at payment processing network  26  or at another entity) to be stored for later comparison with a received authorization request message and/or may send the generated device verification value to the communications module  201 , which may then send this value to another authorization entity (e.g. a merchant or an issuer). 
     The update module  206  may be programmed of configured to maintain and update the authorization databases  215 . In this regard, the update module  206  may receive information about a past transaction or request for a device verification value from some or all of the other modules discussed herein. Moreover, the update module  206  may receive information from other sources, such as directly from the payment processing network  26  and/or the IP Gateway  27  (such as, for example, a generated device verification value for a mobile device  36  (and/or a verification token  34 ) and/or a portable consumer device  32 ). By maintaining information about past transactions and verification requests, it may be possible in some embodiments to more accurately validate future requests for verification, authorization, and/or to generate risk scores for future transactions. 
     The authorization module  207  may be configured or programmed to perform some or all the functions associated with authorizing a financial transaction associated with an authorization request message. The authorization request message may be generated by a merchant and may be associated with a transaction involving the portable consumer device  32 . The authorization request message may include a device verification value that may have been form filled or otherwise inserted into the authorization request message by the merchant in response to an interaction with the mobile device  36  (e.g. via an access device at the merchant). The authorization module  207  may be programmed or configured to compare the received device verification value with a stored device verification value that was generated and stored by the device verification value generation module  205 . In some embodiments, if the two values match, the authorization module  207  may have further assurance that the transaction is valid and may generate an authorization response message authorizing the transaction (or may be more likely to authorize the transaction). The authorization module  207  may also be programmed or configured to execute any further operations associated with a typical authorization and clearing process. This may include retrieving information from one or more databases, including account/transaction information database  220 . 
     In some embodiments, some of the functions described above with regard to the authorization module  207  may be located at one or more of the other entities in the system  20 . For instance, in some embodiments, the merchant may request from the payment processing network  26  (or the validation entity) the value of the stored device verification value. The merchant computer  22  may then compare the device verification value received from the mobile device  36  (e.g. via an interaction with an access device) with the device verification value received from the validation entity. Based at least in part on this comparison, the merchant computer (or other entity such as an issuer) may approve or decline the transaction. 
     The risk score generation module  208  may be configured or programmed to perform some or all the functions associated with generating a risk score associated with a financial transaction that may be used by the payment processing network  26  (e.g. by the authorization module  207 ) or any other authorization entity in the system  20  to authorize a transaction. Some exemplary processes that may utilize a device verification value (e.g. a dCVV2 value) or other information in generating a risk score are described in detail in U.S. patent application Ser. No. 13/184,080 to Hammad entitled “Token Validation for Advanced Authorization,” which is hereby incorporated by reference in its entirety. 
     The validation database  210  may comprise information received and stored about a mobile device  36  (e.g. verification token information, serial numbers, mobile account information, etc), portable consumer device  32  (or payment account), associations between mobile devices  36  and portable consumer devices  32  (e.g. advanced registration or past transactions), validation of a request for a device verification value (or failure), and any other suitable information that may be used to validate a request. Such information may include, for instance, mobile device  36  (and/or verification token) serial numbers that have been identified as fraudulent or have been used successfully in previous transactions (that is, transactions that were approved by an appropriate authority and/or were not later found to be fraudulent), IP addresses or mobile account information associated with a mobile device  36  known to be fraudulent (or not fraudulent), etc. The validation database  210  may also comprise generated dynamic verification values from previously validated requests for verification values. This information may be used by the validation module  204  to validate the mobile device  36  and/or portable consumer device  32 . 
     The account/transaction information database  220  may be programmed or configured to comprise information associated with payment accounts and past transactions. The information may be used to authorize a transaction and/or generate a risk score for a current transaction. Such information may include previous transaction information (such as volume, amount, merchant identifiers, etc.) as well as information as to whether the account has been used in fraudulent transactions in the past (e.g. a listing of account numbers used in prior fraudulent transactions, IP addresses used, etc.). 
     Reference will now be made to  FIGS. 6 and 8 ( a ) for a description of some of the components of an exemplary mobile device  36  and/or an exemplary verification token  34  (as a module and as a separate component). In some embodiments where the verification token  34  may comprise a separate component to the mobile device  36 , the user  30  may connect the verification token  34  to an input of his mobile device  36 . The mobile device  36  can power the verification token  34  in some embodiments. Once the verification token  34  is connected to the mobile device  36 , the mobile device  36  may recognize the presence of the verification token  34  as a valid device, and the verification token  34  may self-install. The verification token  34  may check the mobile device  36  to determine connectivity to a network (e.g. via the Internet or mobile network, etc.). 
     In some embodiments, a verification token  34  may be part of the mobile device  36  (e.g. it may be a software module or an internal hardware and/or software module). This is illustrated in the exemplary embodiment shown in  FIG. 8 , where verification token  34  is illustrated as a module within the mobile device  36 . Indeed, this may be preferred in some embodiments because the verification token  34  (or the functionality associated with the verification token  34 ) could be remotely downloaded to the mobile device  36  or preinstalled in the device. The component of the mobile device  36  that comprises the verification token  34  may utilize some of the other features shown with respect to the mobile device  36  in  FIG. 8  (e.g. contactless element  36 ( g ), microprocessor  36 ( c ), antenna  36 ( a ), etc.) as needed, or may comprise its own separate components. As described above, a verification token  32  (whether an internal, integrated component or external, separable component) may be considered a part of the mobile device  36 . In some embodiments, the mobile device may not comprise a secured element such as verification token  34 , but may provide similar functionality in performing the methods described below and with reference to  FIGS. 3 and 4 . Note that the remaining components that may comprise an exemplary mobile device  36  will be described in more detail below with further reference to  FIG. 8 . 
     If network connectivity is available (e.g. the Internet, a mobile network, etc.), in some embodiments the verification token  34  may automatically attempt to establish a background SSL session to the IPG  27  (or payment processing network  26 ) so that it can be used as a part of a validation process. In some embodiments, the session may not be established until a user  30  requests a connection to be established. 
       FIG. 6  shows some components that may be present in a verification token  34  within, or coupled to, a mobile device  36  in some embodiments. For example, the verification token  34  may include an application, such as the self-installing driver  650 , so that the verification token  34  may install itself automatically after the verification token  34  is inserted into and recognized by the mobile device  36  (e.g. when the verification token  34  may comprise an external component). The verification token application may be able to connect to a backend host, perhaps at a predefined IP address, using a background secure SSL browser session. A terminal application  670  and heartbeat application  680  may be used to establish and maintain this browser session. If the session connection is successfully established, the verification token  34  may identify itself (and/or the mobile device  36 ) to the IPG  27  by providing its unique token serial number, IP address, mobile device account number, mobile device serial number, etc. to the IPG  27 . Other information may also be passed (e.g., password, encryption keys, etc.) to the IPG  27  at this point. 
     The exemplary embodiment of the verification token  34  illustrated in  FIG. 6  may comprise a separate component that may connect to the mobile device  36  using connectivity module  630 . The verification token  34  (whether internal to the mobile device or coupled thereto) may also comprise a secure element  620  (e.g., a chip such as a smart card chip, which has sufficient data and security protocols and hardware), a wireless/contactless reader  610  capable of reading identification information from a portable consumer device (or a module for using a contactless interface of the mobile device  36 ), built in memory  640 , a self-installing driver  650 , a form fill application  660 , a terminal application  670 , and a heartbeat application  680 . The verification token  34  may also have other features such as a keyboard buffer capability and a unique serial number associated with the verification token  34 . However, embodiments are not so limited. 
     Although  FIG. 6  includes features and components of a verification token  34  that may be related to embodiments where the verification token  34  is an external component that is coupled to the mobile device  36 , as noted above, this exemplary embodiment was provided for illustration purposes only. The verification token  34  may comprise many other suitable forms. For example, as described above, the verification token  34  may comprise hardware (or software) or other module installed in the mobile device  36 . 
     II. Exemplary Methods 
     Methods according to some embodiments are described below with reference to  FIGS. 3 and 4 , and with further reference to the system elements in  FIGS. 1 and 2 . The methods described below are exemplary in nature, and are not intended to be limiting. Methods in accordance with some embodiments described herein may include (or omit) some or all of the steps described below, and may include steps in a different order than described herein. 
     Referring to  FIGS. 1 and 3 , prior to establishing the first communication channel  38 , in some embodiments, a user  30  may receive hardware and/or software (which may include, for example, a verification token  34 ) for his mobile device  36  from his or her financial institution or another entity. As described above, this hardware and/or software may comprise an internal component of the mobile device  36  or may comprise an external component that is coupled to the mobile device  36  (e.g. either physically or operatively coupled through a communication mechanism such as short range communication interface). The hardware and/or software may also be secured (e.g. tamper proof) such as when comprising a verification token  34 . 
     Reference will now be made to the exemplary method shown in  FIGS. 3( a ) and 3( b ) . Again, this is an exemplary embodiment that is described for illustration purposes only. 
     At step S 300 , a user  30  conducting a transaction may generate a request for a dynamic verification value (e.g. dCVV2 or similar information that may be used to validate a transaction) from the payment processing network  26 . The request may be made via a portable consumer device  32  (such as a credit card or Visa payWave card) interacting with a mobile device  36  (e.g., that may comprise a verification token  34 ). In some embodiments, the portable consumer device  32  may include a chip comprising chip-card type data such as a dynamic counter, dynamic verification value, PAN, cryptogram, etc. As noted above, the mobile device  36  may also include a contactless interface to receive data from the chip in the portable consumer device  32 . In other embodiments, the portable consumer device  32  may interact with the mobile device  36  using a contact mode of operation. For example, the mobile device  36  may have a magnetic card reader, and the portable consumer device  32  may be a payment card with a magnetic stripe, which can be read by the card reader. However, as described above, embodiments are not so limited and the request for the dynamic verification value may be generated by the mobile device using any suitable information (which may or may not include portable consumer device information) and may be generated or initiated at any suitable time (e.g. a consumer could initiate the request using a preregistered username and password, etc.). 
     In some embodiments, prior to sending the request, the user  30  may set up an account with the payment processing network  26 . That is, for instance, a user  30  may establish an association between a mobile device  36  (and/or verification token  34 ) and a portable consumer device  32  prior to requesting a device verification value. In this manner, the payment processing network  26  may anticipate receiving the request from the user  30  and can appropriately process the request. In some embodiments, the user  30  may, in addition to or in lieu of requesting a dCVV2, the mobile device  36  may make a request for a PAN, dPAN, cryptogram, counter or the like to the payment processing network  26 . 
     In step S 301 , the mobile device  36  may establish a first communication channel with the payment processing network  26  (or other validation entity). The communication channel may use any suitable network, including the Internet and/or a private network, and may also utilize any suitable connection method, including use of a mobile network, data network, etc. At step S 302 . the communication channel may be secured in any suitable manner, including an encrypted SSL session. The mobile device  36  (e.g. 
     through use of a verification token  34 ) may send to the IPG  27  information associated with the mobile device  36  (e.g. serial numbers of components, etc.), an encrypted message (e.g. using a unique encryption key), and/or information related to the portable consumer device  32  (e.g. account number, verification values, user information, etc.). This may enable the mobile device  36  to form a secure communications channel  38  with the IPG  27  (or any other validation entity). 
     At step S 303 , the mobile device  36  may generate and send a first request for a device verification value to the payment processing network  26 , IGP  27 , or other validation entity. In some embodiments, the mobile device  36  may send any information (whether encrypted or otherwise) that may be used to validate the request for a device verification value, as was described above. At step S 304 , the request may be received by the validation entity, which may include server computer  210  at the payment processing network  26 . 
     At step S 304 , the first request for the device verification value (and accordingly, the mobile device  36  and/or portable consumer device  32 ) may be validated utilizing the information sent in step S 303 . This may be done in any suitable manner, including those described in detail above. In some embodiments, the validation may involve the IPG  27  communicating with the payment processing network  26 . That is, in some embodiments, the payment processing network  26  may comprise information that is used to validate the first request (and/or mobile device  36 , including in some embodiments a verification token  34 ). This could, for example and as described in detail above, comprise a database of information associated with the mobile device  36  (e.g. serial numbers and corresponding encryption keys, IP addresses, etc.). In addition, when the mobile device  36  is connected to the IPG  27  and the payment processing network  26 , a number of different processes may be performed. For example, in some embodiments, the payment processing network  26  may receive data from the portable consumer device  32  such as PANs, cryptograms, counters, dynamic verification values, etc. This information may be stored in the payment processing network  26  for use in generating a risk score associated with a later transaction and/or validating a mobile device  36  in a future request from the user  30 . 
     At step S 305 , it may be determined if the first request is valid. As noted above, this may comprise any suitable validation method, which may include the use of any information that the validation entity received regarding the first transaction and/or regarding past transactions. In some embodiments, if at step S 306  the first request is not valid, then at step S 310  the validation entity does not send a device verification value. In addition, in some embodiments, the information associated with the first request may be stored at the validation entity (e.g. server computer  210 ) for use in validating future requests. That is, for instance, if a mobile device  36  was used with one portable consumer device  32  and the request was not validated, and later the same mobile device  36  is used with a different portable consumer device  32 ′, then it may be evidence of fraudulent activity. If the first request is validated, then the exemplary method may proceed to step S 307 . 
     At step S 307 , in some embodiments if the first request is validated, the user  30  via the mobile device  36  may receive a message from the payment processing network  26  via the secure communications channel  38  and the IPG  27  that includes a device verification value (e.g. dCVV2 and/or similar information that may be used in a subsequent transaction by the user  30 ). In some embodiments, the message may be sent back through the same channel that the request was sent in, or a different channel, such as an email, text message, or through a web interface. In some embodiments, the information may also be stored in mobile device  36  and the user  30  may (or may not) have access to this information. In such embodiments, as explained below, the mobile device  36  may be used to submit (e.g. send or transmit) the device verification value to a merchant (e.g. via an access device) to perform a transaction, as was described above. The device verification value may also be stored at the payment processing network  26  (or another validation entity) for later use to authorize a financial transaction associated with the portable consumer device  32 . 
     At step S 308 , the user  30  conducts a transaction with a merchant and may choose to pay for that transaction using the portable consumer device  32  (such as a Visa payWave card). That is, for instance, the user  30  may select a good to purchase at a merchant&#39;s store. The merchant may enter the information regarding the transaction (e.g. type of good, price, etc.) and request payment from the user  30 . The user  30  may then designate payment using a payment account that may be associated with the portable consumer device  32  by presenting the portable consumer device  32  to the merchant. The merchant may then enter this information into the merchant computer  22  (e.g. via an access device such as a POS terminal). The user  30  may then be prompted to enter in (or otherwise provide) the first device verification value associated with the portable consumer device  32 . 
     At step S 309 , the first dynamic verification value may be sent (or otherwise provided) to the merchant. That is, the user  30  may provide the received device verification value (e.g. the dCVV2 value) received in step S 304  to the merchant (and/or merchant computer  22 ). In some embodiments, the mobile device  36  may automatically send the device verification value to the merchant (e.g. merchant access device via a POS terminal) using a short range communication. That is, for instance, when the user  30  is prompted in step S 308  to provide the device verification value associated with the portable consumer device  32 , the user may present the mobile device  36  so that it interacts with the merchant&#39;s access device and sends the device verification value. In this manner, neither the user nor the merchant may need access to the device verification value, which may increase the security of some embodiments. Indeed, by directly passing the device verification value from the mobile device  36  to the merchant, embodiments may provide less opportunity for a third party to intercept (or somehow replicate) the device verification value and attempt to conduct a fraudulent transaction. Moreover, by utilizing an interaction between the merchant&#39;s access device and the mobile device  36  to send the device verification value, embodiments may provide a fast and efficient manner of providing added security to a transaction (rather than, for instance, requiring the user or merchant to manually enter the information, although embodiments are not so limited). The use of short range communications may also enable mobile devices of different sizes, shapes, etc. to readily interact with the merchant&#39;s access device in some embodiments. 
     At step S 311 , a first authorization request message corresponding to the first transaction may be generated (e.g., by an access device at the merchant) and sent to the payment processing network  26 . The first authorization request message may comprise, for instance, transaction related information (e.g. information such as a merchant identifier, transaction amount, transaction velocity, etc.), account information (e.g. account number, expiration date, card verification value, etc.), and the received device verification value (e.g. a dCVV2 value). In some embodiments, the first authorization request message generated by the merchant may be form filled with the device verification value received from the user  30  (e.g. from the interaction with the mobile device  36 ) and/or any other transaction related information. That is, the merchant computer  22  may automatically enter the device verification value into a designated field in the authorization request message, which may then be sent to the payment processing network  26 . 
     At step S 312 , the authorization request message may be received by the payment processing network  26  (e.g. by the communications module  201 ). At step S 313  the payment processing network  26  may then compare the dynamic verification value received in step S 312  as part of the authorization request message with the dynamic verification value that was previously received and stored in step S 307  as part of the validation of the first request for the device verification value. If it is determined that the two device verification values match, then at step S 314 , an authorization response message may be generated by the payment processing network  26  approving of the first transaction. If the two device verification values are determined in step S 313  not to correspond (i.e. match), then an authorization response message declining the transaction may be generated at step S 315 . In some embodiments the determination as to whether the two device verification values (e.g. the stored device verification value and the received device verification value included in the authorization request message) correspond may be considered as one factor of a plurality of factors as to whether the transaction is authorized (e.g. it may be included as an input in a calculation of a risk score for the transaction). 
     At step S 316 , the merchant may receive the authorization response message generated in steps S 314  or S 315  and based on this response message, may approve or decline the transaction. At step S 317 , if the transaction was approved by the payment processing network  26 , then the payment processing network  26 , issuer, acquirer, and/or merchant may perform the typical clearing and settling of the transaction. 
     With reference to  FIG. 4 , another flow chart showing the exemplary steps that may be performed by a merchant according to some aspects of embodiments provided herein is shown. At step S 401 , a first transaction may begin, for instance, when a user  30  selects one or more items or services to purchase. The merchant may enter in any transaction related data that may be included in an authorization request message. The user  30  may also present a portable consumer device  32  (such as a payment card) to merchant to pay for the transaction. The merchant may interact with the portable consumer device  32  (e.g. through an access device). The merchant and/or the user  30  may then be prompted to enter a device verification value. For instance, in some embodiments, the payment processing network  26  may initially receive an indication from the merchant that the portable consumer device was associated with the first financial transaction (e.g. in a message from the merchant). The payment processing network  26  may determine (e.g. using a look-up database) whether a device verification value is associated with the portable consumer device  32 , and, if so, may send a message to the merchant requesting that the device verification value be provided. In some embodiments, the merchant may automatically request that the user  30  provide the device verification value (e.g. prior to a communication with the payment processing network  26 ), or the user may present the device verification value when completing the first transaction. 
     At step S 402 , an access device that may be coupled to the merchant computer  22  may interact with the mobile device  36 . That is, for instance, the merchant computer  22  may comprise (and/or be coupled to) an access device that may interact with the mobile device  36 . As described above the interaction may comprise short range wireless communication or any other suitable method of transferring data from one device to another (e.g. a physical interaction). At step S 403 , based on the interaction between the access device that may be coupled to the merchant computer  22  and the mobile device  36 , the merchant computer  22  may receive information from the mobile device, including the device verification value. 
     At step S 404 , the merchant computer  22  may generate an authorization request message that comprises the received device verification value. For example, in some embodiments, after the device verification value is received from the mobile device  36  in step S 403 , the merchant computer  22  may form fill this information into a field of an authorization request message (along with any other information). This automatic form fill step may thereby, in some embodiments, make the additional step of including the device verification value more efficient and less burdensome to the merchant. The generated authorization request message may then be electronically sent by the merchant computer  22  to the payment processing network  36 . 
     At step S 405 , the merchant may receive an authorization response message from the payment processing network  26 . The authorization response message may be based, at least in part, on whether the device verification value that was included in the authorization request message sent by the merchant computer  22  matched a previously stored device verification value associated with the device verification value. At step S 406 , the merchant may approve or decline the transaction based on the received authorization response message, and/or may request additional information from the user  30  to complete to transaction. 
     As noted above, the method shown in  FIG. 4  is provided for illustration purposes and is not intended to be limiting. For instance, in some embodiments, rather than (or in addition to) the merchant computer  22  generating an authorization request message that includes the device verification value, the merchant computer  22  may determine whether the device verification value received from the mobile device  36  matches a stored verification value that was previously associated with the portable consumer device  32 . For instance, in some embodiments, the merchant computer  22  may request a stored device verification value from a validation entity (e.g. payment processing network  26 ), and may then compare the device verification value received form the mobile device  36  with the device verification value received from the validation entity. 
     In some embodiments, the merchant may determine whether to approve or decline a transaction associated with a payment device  32  based on, for instance, information received from the payment processing network (e.g. when the merchant comprises a merchant processor such as CyberSource®). The information received by the merchant computer  22  from the payment processing network  26  may include, for instance, whether the device verification value provided by the mobile device  36  matches a device verification value previously associated with the portable consumer device  32 . In some embodiments, the merchant computer  22  may receive a risk score associated with the transaction that may be based, at least in part, on whether the device verification value provided by the mobile device  36  matches a previously stored device verification value associated with the portable consumer device  32 . 
     Embodiments may provide some advantages. For example, some embodiments may provide for greater security in conducting transactions when a consumer is located at a merchant (i.e. not involved in an e-commerce or remote transaction). That is, for instance, by using a mobile device as part of a system or method to validate the user and/or a portable consumer device prior to conducting a transaction with the merchant, embodiments may provide increased security (and additional information that may be used to authenticate such transactions) that may prevent (or reduce the number of) unauthorized use of a portable consumer device (such as a payment card) even if a nefarious party is in possession of the portable consumer device. As noted above, typically in brick-and-mortar transactions, the merchant does not request additional information from the user that could otherwise be used to authenticate the transaction. By providing an additional validation step of the portable consumer device, embodiments may thereby provide an efficient, cost effective manner to increase the certainty of the authenticity of such transactions. Moreover, in some embodiments, the device verification value may be passed to the merchant by the mobile device without creating a large burden on either the consumer or the merchant (e.g. neither party may need to manually enter the device verification value to complete the transaction). This may increase the likelihood that the consumer and/or the merchant would be willing to use such an authorization system. In addition, by directly passing the device verification value from the mobile phone to the merchant computer, embodiments may increase the security of the system because a nefarious party may not be afforded the opportunity intercept or copy the device verification value before it is provided to the merchant. 
     III. Exemplary Computer Apparatus, Mobile Device, and Portable Consumer Device 
     Referring now to  FIG. 7  the various participants and elements in  FIGS. 1 and 2  can operate one or more computer apparatuses (e.g., a server computer) to facilitate the functions described herein. Any of the elements in  FIGS. 1 and 2  can use any suitable number of subsystems to facilitate the functions described herein. Examples of such subsystems or components are shown in  FIG. 7 . The subsystems shown in  FIG. 7  are interconnected via a system bus  710 . Additional subsystems such as a printer  703 , keyboard  706 , fixed disk  707  (or other memory comprising computer readable media), monitor  709 , which is coupled to display adapter  704 , and others are shown. Peripherals and input/output (I/O) devices, which coupled to I/O controller  700 , can be connected to the computer system by any number of means known in the art, such as serial port  705 . For example, serial port  705  or external interface  708  can be used to connect the computer apparatus to a wide area network such as the Internet, a mouse input device, or a scanner. The interconnection via system bus allows the central processor  702  to communicate with each subsystem and to control the execution of instructions from system memory  701  or the fixed disk  707 , as well as the exchange of information between subsystems. The system memory  701  and/or the fixed disk  707  can embody a computer readable medium. 
       FIG. 8( a )  shows a block diagram of a mobile device  36  that may be used in some embodiments. The mobile device may be both a notification device that can receive alert messages, a portable consumer device that can be used to make payments, and/or a device that may be used in the systems and method described above related to utilizing a device verification value. The exemplary mobile device  36  may comprise a computer readable medium and a body as shown in  FIG. 8( a ) . The computer readable medium  36 ( b ) may be present within the body  36 ( h ), or may be detachable from it. The body  36 ( h ) may be in the form a plastic substrate, housing, or other structure. The computer readable medium  36 ( b ) may be in the form of (or may be included in) a memory that stores data (e.g., issuer account numbers, loyalty provider account numbers, etc.) and may be in any suitable form including a magnetic stripe, a memory chip, etc. The memory may store information such as financial information, transit information (e.g., as in a subway or train pass), access information (e.g., as in access badges), serial numbers, mobile account information, and any other suitable information that may be used in validating the mobile device  36 . Financial information may include information such as bank account information, loyalty account information (e.g., a loyalty account number), a bank identification number (BIN), credit or debit card number information, account balance information, expiration date, consumer information such as name, date of birth, etc. Any of this information may be transmitted by the mobile device  36 . 
     In some embodiments, information in the memory may also be in the form of data tracks that are traditionally associated with credit cards. Such tracks include Track 1 and Track 2. Track 1 (“International Air Transport Association”) stores more information than Track 2, and contains the cardholder&#39;s name as well as account number and other discretionary data. This track is sometimes used by the airlines when securing reservations with a credit card. Track 2 (“American Banking Association”) is currently most commonly used. This is the track that is read by ATMs and credit card checkers. The ABA (American Banking Association) designed the specifications of this track and all world banks abide by it. It contains the cardholder&#39;s account, encrypted PIN, plus other discretionary data. 
     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. Contactless element  36 ( g ) is associated with (e.g., embedded within) phone  36  and data or control instructions transmitted via a cellular network may be applied to 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 hence the cellular network) and an optional contactless element  36 ( g ), or between another device having a contactless element (e.g. a POS terminal or a portable consumer device). 
     Contactless element  36 ( g ) may be capable of transferring and receiving data using a near field communications (“NFC”) capability (or near field communications medium) typically in accordance with a standardized protocol or data transfer mechanism (e.g., ISO 14443/NFC). Near field communications capability may comprise a short-range communications capability, such as RFID, Bluetooth™, infra-red, or other data transfer capability that can be used to exchange data between the mobile device  36  and an interrogation device (or a portable consumer device  32 ). That is, 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 and/or control instructions via both cellular network (or any other suitable network, such as through the Internet or other data network) and short range communications capability. 
     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 phone  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). 
     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 devices can operate in either a contact or contactless mode. 
     An example of a portable device  32 ″ in the form of a card is shown in  FIG. 8( b ) .  FIG. 8( b )  shows a plastic substrate  32 ( m ). A contactless element  32 ( o ) 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 user name may be printed or embossed on the card. Also, a magnetic stripe  32 ( n ) may also be on the plastic substrate  32 ( m ). The portable device  32 ″ may also comprise a microprocessor and/or memory chips with user data stored in them. 
     As shown in  FIG. 8( b ) , the portable device  32 ″ may include both a magnetic stripe  32 ( n ) and a contactless element  32 ( o ). In other embodiments, both the magnetic stripe  32 ( n ) and the contactless element  32 ( o ) may be in the portable device  32 ″. In other embodiments, either the magnetic stripe  32 ( n ) or the contactless element  32 ( o ) may be present in the portable device  32 ″. 
     The above description is illustrative and is not restrictive. Many variations of the invention will become apparent to those skilled in the art upon review of the disclosure. The scope of the invention should, therefore, be determined not with reference to the above description, but instead should be determined with reference to the pending claims along with their full scope or equivalents. 
     One or more features from any embodiment can be combined with one or more features of any other embodiment without departing from the scope of the invention. 
     A recitation of “a”, “an” or “the” is intended to mean “one or more” unless specifically indicated to the contrary
