CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a divisional application of U.S. application Ser. No. 14/501,812, filed Sep. 30, 2014, entitled “Mobile Wallet Authentication Systems and Methods,” which is a continuation-in-part application of U.S. application Ser. No. 14/266,580, filed Apr. 30, 2014, entitled “Mobile Wallet Using Tokenized Card Systems and Methods.” Both of these applications are incorporated by reference herein in their entireties. 
    
    
     BACKGROUND 
     The present disclosure relates generally to the field of systems that use mobile devices to transfer funds. More specifically, the present disclosure relates to systems and methods for enabling individuals to use their electronic devices to transfer funds, purchase products and services. 
     Payments for products and services are often completed using credit cards, debit cards, checks, or cash. At the same time, most people carry some type of mobile handheld electronic device, such as a cellular phone, smart phone, mobile handheld wireless e-mail device, personal digital assistant, portable gaming devices, and so on. Most of these devices tend to have a wireless Internet connection. A person may wish to make payments to merchants or other individuals using these mobile devices. Likewise, a person may wish to transfer funds to other individuals using their mobile devices. Enhanced systems and methods of facilitating such transactions would be desirable. 
     SUMMARY 
     According to one example embodiment, a computer system receives an indication from a user that the user wishes to perform a mobile wallet transaction to transfer funds to a recipient using a mobile device. The transaction is authenticated by the computer system. The authentication includes receiving login credentials manually entered by the user and determining that the login credentials match stored login credentials for the user. The authentication further includes determining that the mobile device has a device token stored thereon that matches a device token stored in a database of the computer system. The device token uniquely identifies the mobile device in the computer system. The authentication further includes determining that the mobile device has a customer token stored thereon that matches the customer token stored in the database. The customer token uniquely identifying the customer in the computer system. The computer system transmits the funds to the recipient responsive to the authenticating step. 
     According to another example embodiment, a financial institution computer system creates a new financial account for a user. The financial institution computer system activates the new account as a source of funds for a mobile wallet. The user does not need to take any action outside of the mobile wallet to have the account activated as a source of funds for the mobile wallet. 
     According to another example embodiment, a computer system receives an indication from a user that the user wishes to create a mobile wallet. The computer system accesses a database to retrieve a list of one or more accounts held by the user at a financial institution. The computer system generates a screen display to present to the user via a mobile device, the screen display showing the list of accounts held by the user. The computer system receives a user selection of at least one of the accounts. In response to the user selection, the at least one account is provisioned to the mobile wallet. 
     According to another example embodiment, a financial institution computer system receives online banking login credentials from a mobile device at an online banking website of a financial institution to initiate a mobile online banking session for a user. During the online banking session, the computer system presents the user with a link to have a mobile wallet circuit placed on the mobile device. The computer system places the mobile wallet circuit on the mobile device responsive to a user selection of the link, including transmitting a mobile wallet application to the mobile device and causing installation of the mobile wallet application to occur on the mobile device.

     DETAILED DESCRIPTION 
     Before turning to the figures which illustrate example embodiments, it should be understood that the application is not limited to the details or methodology set forth in the following description or illustrated in the figures. It should also be understood that the phraseology and terminology employed herein is for the purpose of description only and should not be regarded as limiting. 
     Referring generally to the figures, systems and methods for providing token generation and validation features for a payment processing system are described. More particularly, the present disclosure relates to the use of codes with tokens for validation during payment processing. The codes may be transmitted, e.g., using optical image methods (e.g., QR code), NFC, wireless, Bluetooth, low energy Bluetooth, RFID, hypersonic, Wi-Fi, cellular 3G, 4G, GSM, LiFi, etc. The systems and methods described herein may be implemented for users having a mobile wallet implemented on a mobile device. The mobile wallet allows the user access to accounts via the mobile device to provide payments to merchants or other users. The systems and methods described herein allow for integration between a mobile wallet server and a merchant for processing a payment. 
     In an embodiment of the present disclosure, a code representing a substitute card number may be generated and formatted for use as part of a validation system. When a user registers for a mobile wallet account, a customer token may be generated for the user and a device token may be generated for the device used by the user. The customer token and device token may be used to verify further transactions between the user and the mobile banking system or mobile wallet account. 
     When the user logs into his or her mobile wallet and wishes to make a payment using funds in the user&#39;s accounts, the customer token and device token are sent or provided to a server system. A substitute card number (tokenized) including a trace ID number as described below may be provided to the user by a mobile wallet computer system. The mobile wallet computer system and a point of sale (POS) device, e.g., at the store location at which the payment is to be submitted, use the substitute credit card number to authenticate the transaction. The substitute card number may be formatted to include a portion of an actual card number held by the user, e.g., so that the last four digits appearing on a receipt provided to the user match those of the user&#39;s actual card number, even though a substitute card number was provided to the merchant to process the payment. 
     In various embodiments, the substitute card number (tokenized) including a trace ID number as described below may be converted back into the actual credit card number by a mobile wallet computer system. For example, the merchant point of sale device may provide the substitute card number to an acquirer processor computer system, which in turn may provide the substitute card number to the mobile wallet computer system. In response, and after authenticating the transaction, the mobile wallet computer system may return the actual card number to the acquirer processor computer system. The acquirer processor may then provide the actual card number to a payment network, which in turn may provide the card number to a source account (credit card issuer) computer system for payment processing. 
     In other embodiments, rather than providing the substitute card number to the mobile wallet computer system, the acquirer processor computer system may provide the substitute card number to a payment network computer system. In turn, the payment network computer system may provide the substitute card number to the mobile wallet computer system, which, after authenticating the transaction, may then return the actual card number to the payment network computer system. The payment network computer system may then provide the actual card number to a source account computer system for payment processing. 
     Referring to  FIG.  1   , a computer-implemented payment processing system  100  is shown, according to an example embodiment. The payment processing system  100  may be used to set up and utilize a mobile wallet. The user may be a business entity and/or an individual consumer that has one or more source accounts with a financial institution. The source accounts may include business or consumer demand deposit, credit card, debit card accounts, lines of credit, and so on. The mobile wallet account may be created for the user to transmit funds from a source account to pay for goods or services to a merchant. Additionally, funds can be transferred from the source account to another person. 
     The payment processing system  100  may include, among other systems, a mobile device  110 , a mobile wallet bank computer system  120 , a source account bank computer system  130 , a merchant computer system  140 , an acquirer/processor computer system  145  and a payment system  150 . The various systems may communicate through a network  160 , which may include one or more of the Internet, cellular network, Wi-Fi, Wi-Max, a proprietary banking network, or any other type of wired or wireless network. In some embodiments, the mobile wallet bank computer system  120  and source account bank computer system  130  may be owned by the same entity. In other embodiments, the mobile wallet bank computer system  120  and source account bank computer system  130  may be owned by a different entity. 
     The mobile wallet bank computer system  120 , the source account bank computer system  130 , the acquirer/processor computer system  145  and the payment system  150  may each include a computer system (e.g., one or more servers each with one or more processing circuits), each including a processor and memory. The processors may be implemented as application specific integrated circuits (ASICs), one or more field programmable gate arrays (FPGAs), a group of processing components, or other suitable electronic processing components. The memory may be one or more devices (e.g., RAM, ROM, Flash memory, hard disk storage, etc.) for storing data and/or computer code for completing and/or facilitating the various processes described herein. The memory may be or include non-transient volatile memory, non-volatile memory, non-transitory computer storage media. The memory may include data base components, object code components, script components, or any other type of information structure for supporting the various activities and information structures described herein. The memory may be communicably connected to the processor and include computer code or instructions for executing one or more processes described herein. 
     The mobile wallet account may be established in a variety of ways, for example, through an online banking area of a website of the banking institution that operates the mobile wallet bank computer system  120 . 
     The mobile device  110  may be used by an individual user (e.g., a business owner or employee, a consumer, etc.) to create and interact with a mobile wallet account. The mobile device  110  may, for example be, a cellular phone, smart phone, mobile handheld wireless e-mail device, personal digital assistant, portable gaming device, or other suitable device. The mobile device  110  includes a network interface logic  112 , a display device  114 , an input device  115 , and a mobile wallet client application  116 . The network interface logic  112  may include, for example, program logic that connects the mobile device  110  to the network  160 . For example, the mobile device  110  may receive and display screens including account information, transaction instructions, and so on. In one embodiment, a screen may be used to request a username and password information from the user, to prompt the user to provide information regarding the amount of a payment and which merchant or individual (e.g., name, address, phone number or e-mail, a selection of a recipient by the user from his/her memory or from the mobile device  110 , etc.) is to receive the payment. Such screens are presented to the user via the display device  114 . The input device  115  may be used to permit the user to initiate account access and to facilitate receiving requested information from the user. The input device  115  may include, for example, a keypad or keyboard, a touchscreen, a microphone, or any other device that allows the user to access the payment processing system  100 . As will be appreciated, in addition to or instead of the mobile device  110 , users may also be provided with the ability to access the payment processing system  100  using another type of computer (e.g., a desktop or laptop computer executing browser software) to perform the operations described herein as being performed by the mobile device  110 . 
     The mobile wallet client application  116  or mobile wallet circuit may include program logic executable by mobile device  110  to implement at least some of the functions described herein. In order to make the mobile wallet circuit  116 , the mobile wallet bank computer system  120  may provide a software application and make the software application available to be placed on the mobile device  110 . For example, the mobile wallet bank computer system  120  may make the software application available to be downloaded (e.g., via the online banking website of the mobile wallet bank, via an app store, or in another manner). Responsive to a user selection of an appropriate link, the mobile wallet application may be transmitted to the mobile device and may cause itself to be installed on the mobile device  110 . Installation of the software application creates the mobile wallet circuit on the mobile device  110 . Specifically, after installation, the thus-modified mobile device  110  includes the mobile wallet circuit (embodied as a processor and instructions stored in non-transitory memory that are executed by the processor). 
     As will be appreciated, the level of functionality that resides on the mobile device  110  as opposed to the mobile wallet bank computer system  120  may vary depending on the implementation. The client application  116  may provide an interface that is configured to receive and display mobile web pages received from the mobile wallet bank computer system  120  (e.g., web pages prompting the user to provide information to create an account, web pages displaying account balance information and past transactions, and so on). Upon initiation of a transaction, the client application  116  may request data from the mobile wallet computer system  120  to generate a unique code/token. The unique code/token may then be transmitted by the mobile device  110  to the merchant computer system  140  as part of a transaction to facilitate authentication of the transaction. In other embodiments, the mobile wallet bank computer system  120  may implement the code/token generator. 
     The mobile wallet client application  116  is used in connection with merchant computer system  140  located at a brick and mortar store location. Additionally, the mobile wallet application  116  may also be used in connection with online merchant transactions. In another embodiment, merchants may be provided with the ability to have a mobile storefront and profile within the mobile wallet client application  116 . For example, merchants may be provided with the ability to display marketing material, provide information, and promote products or discounts. Merchants may also be provided with the ability to sell items directly through their mobile storefront for the account holder to purchase from within the mobile wallet client application  116 . 
     The mobile wallet client application  116  may offer a user to choose any one of the accounts for transferring funds to the merchant for goods or services. An account holder may select a default account that is used to make payments. The account holder may use account selection logic to select the account the account holder wants to use to pay the merchant or other recipient. 
     The mobile wallet bank computer system  120  includes code/token generator  118 , account processing logic  122 , an accounts database  124 , network interface logic  126 , transaction verification logic  127 , and an account directory  128 . In one embodiment, the mobile wallet bank computer system  120  is operated by a first banking entity that maintains and handles transaction processing for mobile wallet accounts. The mobile wallet accounts may be created via interaction of the mobile wallet application  116  with the mobile wallet bank computer system  120 . The user may or may not have conventional bank accounts with the banking entity that maintains the mobile wallet bank computer system  120 . If the user does not have bank accounts with the entity that maintains the mobile wallet bank computer system  120 , then accounts associated with another banking entity may also be used. Again, in such an embodiment, the flow of funds into and out of the mobile wallet accounts may also be processed by the first banking entity using the mobile wallet bank computer system  120 . 
     The mobile wallet bank computer system  120  is configured to store information regarding mobile wallet accounts. By way of example, information for a specific mobile wallet account  125  is shown as being stored in the accounts database  124 . As will be appreciated, the accounts database  124  may also store information regarding many other mobile wallet accounts (not shown). As will also be appreciated, the extent to which transaction details are tracked and maintained in account processing logic  122  and stored in a storage database provided by the mobile wallet bank computer system  120  may vary in differing embodiments. The account database  124  may store details regarding credit card accounts. In particular, the account database  124  may store each financial transaction that occurred. Each financial transaction may include the amount of the transaction and the merchant. 
     The code generator  118  may receive a request from an account holder to initiate a transaction. In response, the code generator  118  may generate a code that may be transmitted by the mobile device  110  to the merchant computer system  140 . As will be appreciated, any suitable method may be used to transmit the code. In various embodiments, the code may be transmitted using optical image methods (e.g., QR code), NFC, wireless, Bluetooth, low energy Bluetooth, RFID, hypersonic, Wi-Fi, cellular 3G, 4G, GSM, LiFi, etc. For purposes of providing an example, it is sometimes assumed in the discussion of  FIGS.  1 - 11    that an optical method is used (e.g., QR code). In various embodiments, the code may be generated without the account holder providing the merchant&#39;s name or amount of transaction. The code generator  118  can be configured to generate a code that incorporates at least one of a date, time, trace ID, unique transaction identifier, and geographic location of the mobile device. In other embodiments, the code generator  118  may generate a tokenized numerical code that is in the Track 1 and Track 2 formats as specified by the ISO 8583 specification. 
     The code may incorporate at least a portion of an account number for a source account that is associated with the mobile wallet account. The incorporated user account number indicates the payment method to be associated with the transaction (e.g., which of the user&#39;s credit cards will be used for the transaction). The code may be generated such that a combination of random digits and a portion of a payment card number are included in the code, e.g., so that the last four digits appearing on a receipt provided to the user match those of the user&#39;s actual card number, even though a substitute card number was provided to the merchant. The various fields of such a code, and the format of such a code, are described in greater detail in  FIGS.  5 - 8   . 
     The mobile wallet account  125  holds funds that are transmitted to a recipient  140  upon receiving instructions from the user through the mobile device  110 . As described below, funds flow into and out of the mobile wallet account  125  through the payment system  150 . The mobile wallet account logic  120  is connected to the payment system  150  through the network  160 . The network interface logic  126  may include, for example, program logic that connects the mobile wallet bank computer system  120  to the network  160 . 
     The mobile wallet bank computer system  120  further includes transaction verification logic  127 . The transaction verification logic  127  may receive a transaction amount from the merchant computer system  140 . In some embodiments, the transaction verification logic  127  may generate a message to send to the mobile device  110  for verifying the transaction amount. Upon receiving the verification message, the account holder via the mobile device  110  may approve or deny the transaction amount for the mobile wallet bank computer system  120 . 
     The source account computer system  130  includes account processing logic  132 , an accounts database  134 , and network interface logic  136 . In an example embodiment, as previously indicated, during registration process for the mobile wallet account  125 , the user may be prompted to identify a source account  135 , that is, a source of funds for the mobile wallet account. The source account  135  may be an existing demand deposit account or a credit card account held by the user with the same financial institution or another financial institution. When the mobile wallet account  125  is created, the user is prompted to provide bank account information (e.g., routing number and/or account number) for the source account  135  that is used as a source of funds for the mobile wallet account  125 . Thus, the financial institution that provides the mobile wallet account  125  for the user and the financial institution that typically provides banking services to the user may be two different financial institutions. In such situations, a second banking entity that maintains and handles transaction processing for source accounts may operate the source account computer system  130 . In other situations, the computer systems  120  and  130  may be considered as being integrated in a single payment processing system (e.g., if the two financial institutions are the same). As will be appreciated, in a situation where the mobile wallet computing system  120  has many users, some users may have all their mobile wallet source accounts at the same bank that operates the mobile wallet computer system  120 , some users may have all their mobile wallet source accounts at a bank other than the same bank that operates the mobile wallet computer system  120 , and some users may have some of their mobile wallet source accounts at the same bank that operates the mobile wallet computer system  120  and other of their mobile wallet source accounts at a bank other than the bank that operates the mobile wallet computer system  120 . 
     The merchant computer system  140  may be used at a point of sale location to conduct transactions with the account holder. For example, the merchant computer system  140  may include a point of sale computer system such as a cash register system connected to a central server system operated by the merchant. As another example, the merchant computer system  140  may include a mobile computing device (e.g., smart phone, tablet PC, etc.) operated by a store clerk as the clerk moves throughout the store. Again, the mobile computing device in such an embodiment may connect to a central server system operated by the merchant. 
     The merchant computer system  140  includes network interface logic  142 , a code scanner  144 , location indicator logic  146 , fund requesting logic  148 , and fund receiving logic  149 . In one embodiment, the network interface logic  142  is configured to allow the merchant computer system  140  to communicate with the network  140 . The network interface logic  142  sends and receives data from the mobile device  110  and the mobile wallet bank computer system  120 . 
     The code scanner  144  may be configured to scan codes, such as but not limited to, optically scanned or non-optically scanned codes. In the embodiment of the present disclosure, the code scanner  204  scans one or more types of codes. After receiving the code, the scanner  144  determines the information that was incorporated into the code by the mobile device  110  or the mobile wallet bank computer system  120  that generated the code, as described below. 
     The location indicator logic  146  provides an indication of the geographic location of the code scanner  144 . In one embodiment, the location indicator logic  146  may be programmed with the known address of the merchant location as the location of the code scanner, such that the location of the merchant can be compared with the location of the mobile device  110  as part of authenticating a transaction. 
     The fund requesting logic  148  communicates a fund request via the network interface logic  142  to the acquirer/processor computer system  145 . In some embodiments, the fund requesting logic  148  may send the tokenized card number (that includes an issuer identification number (IIN), trace ID (generated numbers), checksum helper digit, last 4 digits of the actual card number) received from the user to the acquirer/processor computer system  145 . In response to receiving a tokenized card number, the acquirer processor computer system  145  sends the tokenized card number to the mobile wallet bank computer system  120 , which in turn sends the actual card number and a trace ID (embedded within the issuer discretionary field) to the acquirer processor computer system  145 . The fund receiving logic  149  determines when payment has been received by the merchant computer system  140  and allocates the payment accordingly. 
     The merchant computer system  140  may further connect to or integrate with other hardware. For example, in one embodiment, the merchant computer system  140  may connect to a card reader for reading credit cards, debit cards, stored value cards, and so on. As another example, the merchant computer system  140  may be configured to prompt the user to provide a random security code. The random security code may be generated by the mobile device  110 , by a separate security dongle, or in another manner. The security code may be provided to the merchant computer system  140  directly by the mobile device, may be keyed into the merchant computer system  140  (e.g., by a store clerk), or may be received in another manner. 
     The acquirer processor computer system  145  includes a computer system that transmits and receives messages from the mobile wallet bank computer system  120 , the merchant computer system  140 , or the payment system  150 . In various embodiments, the acquirer processor computer system  145  may receive the tokenized card information and route the received information to the mobile wallet bank computer system  120 . In other embodiments, the acquirer processor computer system  145  may receive the actual card information from the mobile wallet bank computer system  120  with the trace ID embedded within the issuer discretionary field in track 2 format. In some embodiments, the acquirer processor computer system  145  may transmit the actual card information with the trace ID to the payment system  150 . In various embodiments, the acquirer processor computer system  145  may process the payment in the mobile wallet system described herein. 
     In other embodiments, and as previously noted, the acquirer processor computer system  145  may instead route the tokenized card information with the trace ID number to payment system  150 . In turn, the payment system  150  may provide the substitute card number to the mobile wallet computer system  120 , which, after authenticating the transaction, may then return the actual card number to the payment system  150 . The payment system  150  may then provide the actual card number to a source account computer system  130  for payment processing. 
     The payment system  150  may comprise at least one card network  152 . In some embodiments, the payment system comprises multiple card networks  152 , such as Visa®, MasterCard®, American Express®, Discover®, Diners Club®, etc. In such an embodiment, the appropriate card network  152  may be determined based on the first digit of the actual account number (i.e., “4” corresponding to Visa®, “5” corresponding to Mastercard®, “6” corresponding to Discover®, and so on). The acquirer processor computer system  145  may therefore route the transaction to the appropriate card network  152  based on the first digit of the substitute credit card number. The card network  152  may then route the substitute card number to the mobile wallet computer system  145  based on the issuer identification number (IIN). For example, the card network  152  may identify the credit card number provided by the acquirer processor computer system  145  as being a substitute credit card number and not an actual credit card number based on the IIN. In one embodiment, this identification occurs based on the IIN being a card network-owned IIN that has been licensed to the mobile wallet bank and that has been designated by the mobile wallet bank and the card network for use in mobile wallet transactions. In such an arrangement, the acquirer processor computer system  145  processes the transaction like any other credit card transaction, and it is not necessary for the acquirer processor computer system  145  to be aware that the transaction is a mobile wallet transaction. Given the relatively limited number of card networks (e.g., Visa®, MasterCard®, American Express®, Discover®, Diners Club®, etc.), and given the much larger number of acquirer/processors, such an arrangement has the technical benefit of reducing modifications to existing computer systems to implement the features described herein. In other embodiments, this identification is made based on an indication from the merchant computer system  140  and/or the acquirer processor computer system  145  that the transaction is a mobile wallet transaction. Based on the IIN, the card network  152  may transmit the substitute card number to the mobile wallet computer system in turn receive the actual card number, expiration date, and authentication code (e.g., cvv, etc.) from the mobile wallet bank computer system  120 . 
     The payment processing system  100  may further include additional bank computer systems that may allow the mobile wallet platform of the present disclosure to be accessed by consumers and merchants that bank at various different banking institutions. The additional bank computer systems may provide the services described herein through multiple banks, allowing for broader adoption of the mobile wallet platform. 
       FIG.  2    illustrates a process  200  that may be implemented by the system in  FIG.  1   . When a user wishes to make a payment at a merchant, for example, the user may access the mobile wallet client application  116  by entering a PIN or other login credentials and then selecting a “pay now” or similar button. For example, the user may be located at a merchant location and may wish to pay for a good or service. As another example, the user may be located away from the merchant location or be engaged in an online transaction. 
     At step  201 , the mobile device  110  requests access to funds in the mobile wallet via the mobile wallet bank computer system  120  to pay for a good or service. The mobile device  110  may provide a PIN, a customer ID, and a device ID to the mobile wallet bank computer system  120 . The user may be identified and authenticated based on a match of these three data elements with information stored in the mobile wallet bank computer system  120 . Further, the user&#39;s mobile wallet account information may be located/determined. 
     Next, at step  202 , the mobile wallet bank computer system  120  may generate a tokenized credit card number as described in greater detail below. The tokenized credit card number may include a few generated numbers and a few numbers from the actual credit card number. In one embodiment, the tokenized credit number starts with an issuer identification number (IIN) that corresponds to the mobile wallet bank computer system  120 , ends with the last four digits of the actual credit card account number of the credit card that is being used in the transaction, and further includes intervening digits including a trace ID and a checksum helper digit. The trace ID is described in further detail below and allows for enhanced authentication during the payment process. The may permit checksum verification of the tokenized credit card number. Various checksum algorithms may be used to verify that the tokenized credit card number is a valid credit card number. 
     The tokenized credit card number may be transmitted to the mobile device  110  in the form of a code. For example, the data may be encoded in accordance with the track 1 and/or track 2 formats used in the magnetic stripes of credit cards. In some embodiments, the code is formatted in Track 2 format. In either case, the primary account number field may contain the tokenized credit card number and the issuer discretionary field may contain the payment token. In yet other embodiments, another format is used. 
     At step  203 , the tokenized credit card number is transmitted to the mobile device  110 . If the mobile wallet bank computer system  120  and the source account computer system  130  are different computer systems (e.g., if the user is using a credit card that is provided by a different bank than the bank the operates the mobile wallet computer system  120 ), then the trace ID may also be sent to the source account computer system  130  at step  203 . 
     At step  205 , the mobile device  110  may display or otherwise transmit the tokenized credit card number to merchant computer system  140  (e.g., using a QR code, NFC, wireless, Bluetooth, low energy Bluetooth, RFID, hypersonic, Wi-Fi, cellular 3G, 4G, GSM, LiFi, or other method). At step  207 , after receiving the tokenized card number, the merchant computer system  140  sends the transaction to an acquirer processor computer system  145  for processing. 
     Next, at step  209 , the acquirer processor computer system  145  sends the tokenized card number to the mobile wallet bank computer system  120 . After receiving the request from the acquirer processor computer system  145 , the mobile wallet bank computer system  120  may determine the actual card number and send the actual card number back to the acquirer processor at step  211 . In one embodiment, the determination of the actual card number may occur by searching for the account information associated with the payment token and/or trace ID within the tokenized card number. Additionally, the trace ID from the tokenized card number may be sent with the actual card number at step  211 . At this point, the issuer discretionary field is no longer need for the payment token, hence, the trace ID may be sent to the acquirer processor computer system  145  in the issuer discretionary field. 
     At step  212 , the acquirer processor computer system  145  sends the actual card number and the trace ID to the payment system  150  for processing a payment. The payment system  150  sends the actual card number with the trace ID and the transaction amount to the source account bank computer system  130  at step  213 . The source account bank computer  130  may retrieve the trace ID that was received from the mobile wallet bank computer system  120  by searching for the actual card number that was received from the payment system  150 . The source account bank computer  130  may compare the trace ID that was received/stored at step  203  with the trace ID that was received from the payment system  150  at step  213 . Assuming there is a match, the source account bank computer  130  may issue an approval for the transaction. After verifying the actual card number and the trace ID in the issuer discretionary field, the source account bank computer system  130  may send an approval to the payment system  150  at step  215 . The approval message may be sent from the payment system  150 , to acquirer processor computer system  145 , to the point of sale system  140 , in steps  217  and  219 . Upon receiving the approval message the point of sale system  140  may generate a receipt for the user. In some embodiments, the receipt may be sent to the mobile device  110  electronically. In other embodiments, the receipt may be printed physically at the point of sale location. The receipt may include the last four digits of the actual credit card account number of the credit card that was used in the transaction. 
     The use of the payment token and trace ID as described herein allows for two levels of authentication. The payment token is generated by the mobile wallet computer system at step  202 . The payment token is then transmitted to the mobile device  110 , then to the merchant computer system  140 , then to the acquirer processor computer system  145 , and eventually back to the mobile wallet computer system  120  where it is matched with the original payment token generated at step  202 . Similarly, the Trace ID is also generated by the mobile wallet computer system at step  202 , and then transmitted to the mobile device  110 , then to the merchant computer system  140 , then to the acquirer processor computer system  145 , and eventually back to the mobile wallet computer system  120  where it is matched with the Trace ID generated at step  202 . In the case of the Trace ID, however, the Trace ID is then further transmitted back to the acquirer processor computer system  145 , then to the payment system  150 , and then to the source account computer system  130  where it is matched with the Trace ID generated at step  202 . Accordingly, the trace ID used in conjunction with the tokenized credit card number allows both the mobile wallet bank computer system  140  and the source account bank computer system  130  to authenticate the transaction. Using the trace ID in the above described manner may permit the source account bank computer system  130  and the mobile wallet bank computer system  120  to verify the trace ID at least twice prior to approving a transaction and transferring funds. Further, and as described in greater detail below, the trace ID may be used by the source account computer system  130  to determine whether the credit card transaction was a mobile wallet transaction (e.g., as opposed to an in-person card-present transaction involving use of the user&#39;s physical credit card, as opposed to an online transaction, and so on). Hence, the source account bank computer system  130  may provide a different customer experience to the mobile wallet user. The source account bank computer system  130  may also determine risk differently for transactions that use a mobile wallet. 
     In some embodiments, instead of embedding the trace ID in a tokenized credit card account number at step  202 , the actual credit card number is transmitted to the mobile device  110  and the merchant computer system  140 . In such an embodiment, the trace ID may be included in the issuer discretionary field at step  202 , and the payment token may be communicated in another manner or another payment matching mechanism may be used. The trace ID may be stored in the issuer discretionary field and may travel though the payment processing system, until it is verified by the source account bank computer system  130 . After being verified by the source account bank computer system  130 , the transaction may be approved and the funds may be transferred from the source account bank computer system to the acquirer processor computer system  145 . In other embodiments, the same financial institution may own the source account bank computer system  130  and the mobile wallet bank computer system  120 . 
     Referring now to  FIG.  3    and  FIGS.  3 A- 3 F ,  FIG.  3    is a flow chart of a process  300  detailing a user registration process and a token generation process during registration, according to an example embodiment.  FIGS.  3 A- 3 F  are screens that may be displayed to the user during the process  300  of  FIG.  3    according to an example embodiment. Process  300  may be executed by a mobile device  110  and a mobile wallet bank computer system  120  that is configured to create and manage a mobile wallet account. Process  300  may be executed for a user who wishes to start a mobile wallet account  125  for a source account  135 . In the example of  FIG.  3   , it is assumed that the user has an account at the bank that operates the mobile wallet computer system  140 . As will be appreciated, a similar process may be used for users that have accounts only at other banks. 
     As previously indicated in connection with  FIG.  1   , a user may perform the registration via an online banking website of the mobile wallet bank. For example, as shown in  FIG.  3 A , a user may select a button  301  for an online banking application on the mobile device  110 . 
     After the button  301  is selected, the user may be presented with a screen as shown in  FIG.  3 B . Process  300  includes receiving user authentication information into the mobile wallet bank computer system  120  using existing financial institution credentials (step  302 ). Existing credentials may include, for example, a username and password combination or card information (card number, account number, expiration date, CVV) for an online banking website of the bank that operates the mobile wallet computer system  120 . For example, in  FIG.  3 B , the credentials are entered in fields  303  and  305 , respectively, of a login screen to the online banking website. In one embodiment, the credentials may match keyboard-entered credentials that are used to access the source account via online banking. In other embodiments, the credentials may match other types of authentication credentials that are used to access online banking (e.g., facial recognition on a captured image or video of the user on a camera of the mobile device, voice or speech recognition captured by an input device of the mobile device, fingerprint authentication, etc.). After providing online banking login credentials as shown in  FIG.  3 B , the user may be taken to a top-level online banking screen as shown in  FIG.  3 C . The screen shown in  FIG.  3 C  shows an overview of accounts and account balances held by the user. 
     Process  300  further includes initiating a registration process for a mobile wallet account with the user (step  304 ). Step  304  includes receiving a user indication to create a new mobile wallet account. In some embodiments, the user may be presented with a menu option on his or her mobile device to create a new mobile wallet account, among other options. For example, in the top-level screen shown in  FIG.  3 C , a button  327  is provided that allows the user to receive additional information about the mobile wallet application. After selecting the button  327  in  FIG.  3 C , the user may be taken to a mobile wallet introductory screen as shown in  FIG.  3 D . In the screen shown in  FIG.  3 D , the user is provided with an option to tour the mobile wallet application and with an option to initiate the mobile wallet registration. Upon selecting button  329 , the mobile wallet registration process is initiated. After selecting the button  329  in  FIG.  3 D , the user may be taken to a first screen for the mobile wallet registration as shown in  FIG.  3 E . 
     Process  300  further includes receiving user account information (step  306 ). Receiving the user account information may include prompting the user to provide mobile wallet login credentials, e.g., a PIN number associated with a debit card or credit card held by the user at the bank. For example, in  FIG.  3 E , the user enters a PIN number in field  331 . The user may also be prompted to identify the source account(s) the user wishes to associate with the mobile wallet account. For example, the user may enter information about accounts held at other banks that may serve as source accounts. In other embodiments, the user may be presented with various fields on the mobile device that allow the user to select one or more source accounts held by the user, to enter account information (e.g., an account number) in one or more fields, or otherwise. For example, as shown in  FIG.  3 F , the user may be presented with a list  333  of accounts the user has with a particular source account bank computer system, and may choose one or more accounts to view account information and to select the account for use with the mobile wallet account. Thus, the mobile wallet may auto-provision the existing accounts of the user to the mobile wallet, without the user having to manually enter the 16-digit credit card account number or other account information (e.g., in the case of other types of financial accounts). The user may further provide information to create a user profile including other information as warranted. In some embodiments, the mobile wallet computer system  120  may establish a connection with the computer systems  130  of other financial institutions, such that the accounts held by the user at the other financial institutions may be auto-provisioned to the mobile wallet as well. In both cases, the user may be provided with information about current account balances regarding the accounts. 
     Process  300  further includes generating a customer token and device token (step  308 ), and sending the customer token and device token to the mobile device of the user (step  310 ). The customer token and device token may be tokens that identify the user and the associated mobile device to the mobile wallet bank computer system in the future. The tokens are encrypted by the mobile wallet bank computer system and provided to the mobile device. The mobile device stores the tokens for future use. In one example embodiment, each time the user accesses the mobile wallet system with a new mobile device  110 , the mobile device is assigned its own device token. A device and customer token are stored on each device in order to bind the device to the user (one device can only have one wallet user, but one user can have multiple devices). Once a mobile device for mobile wallet account is registered, the user only needs to enter their existing PIN to access their mobile wallet from the registered device (which PIN may be typically eight characters or less and consist only of numbers). The full login credentials associated with online banking are not needed (which often consist of a combination of lower case letters, upper case letters, numbers, and special characters (e.g., punctuation marks)). Instead, possession by the user of the registered device provides an additional level of authentication that avoids the need for full login credentials. Additionally, it may be noted that the level of functionality available the user through the mobile wallet may be less than the level of functionality available to the user through the full online banking website, thereby providing further risk mitigation. 
     Process  300  further includes receiving a default payment method from the user (step  312 ) and completing the registration (step  314 ). Step  314  may include a user accepting terms and conditions associated with use of the mobile wallet account. The default payment method may indicate how a user wishes to normally pay for a particular transaction. For example, the user may provide options relating to how to manage overdrafts, whether the total payment should be provided in one or more payments, or otherwise. Process  300  may include storing the default payment method (step  316 ) in the profile database of the mobile wallet bank computer system  120  (or another database of the mobile wallet bank computer system). The default payment method may be recalled by the mobile wallet bank computer system  120  during a future payment process. 
     Process  300  may also include generating and sending an offline code token to the source account bank computer system. The offline code may be used by the payment processing system, and more particularly the source account bank computer system, to execute a payment for the user when the mobile device is offline, or for other account management purposes. In some embodiments, the mobile device may store one or more offline codes to provide to the merchant. The mobile device  110  may not contact the mobile wallet bank computer system  120  and may provide the code to the merchant computer system  140 . 
     As will be appreciated, the arrangement of  FIG.  3    facilitates keeping the list of source accounts that is up to date and accurate to the user. For example, each time a transaction is to be performed, the mobile wallet computer system  120  may access a list of accounts held by the user at the mobile wallet bank. In some cases, an account that was previously active may no longer be active. For example, a user may have reported a physical credit card associated with a credit card account as having been lost or stolen. Prior to presenting a list of available source accounts to the user in the context of a particular transaction, the mobile wallet computer system  120  may determine that a previously-provisioned source account is no longer available as a source of funds. Hence, when the mobile wallet computer system  120  generates a screen display to present to the user via a mobile device showing the list of accounts held by the user at the financial institution, the previously-provisioned source account that is no longer available as a source of funds may be excluded from the list. When the list of available source accounts is presented to the user, the user may select a new source account for the transaction. For example, if the credit card account was the user&#39;s default payment method, the user may select a new default payment method (e.g., an existing demand deposit account). 
     Additionally, the arrangement may also permit new accounts to be activated and added to the mobile wallet, e.g., a new card account, a new savings account, a new line of credit, and so on. In the case of a new card account, the new card account may, for example, be a new credit card account, a new demand deposit account with a debit card, or an existing demand deposit account with a new debit card. 
     For example, in the case of a lost or stolen credit card, the bank may create a new credit card account in replacement of the credit card account for which the physical credit card was reported as having been lost or stolen. When the mobile wallet computer system  120  accesses the list of accounts held by the user, the mobile wallet computer system  120  may identify the new credit card account as being an account that has not yet been provisioned to the mobile wallet. When the screen display is generated showing the list of accounts held by the user, the list may then include the new credit card account, which may be selected by the user for provisioning to the mobile wallet. Again, the new credit card account may be provisioned to the mobile wallet without any manual entry by the user of account information regarding the new credit card account (other than the selection of the new credit card account by the user, indicating that the user wishes to add the new credit card account to the mobile wallet). 
     In the case of a new credit card account, the bank may issue a new credit card account immediately upon learning of the lost or stolen credit card associated with the previous credit card account. Typically, the bank may then mail the user a new physical/plastic credit card. Upon receiving the new physical credit card, the user may then activate the new credit card, e.g., by calling a credit card activation phone number printed on a sticker that has been placed on the card. 
     In some embodiments, the user may be provided with the option of activating the new credit card account through the mobile wallet. For example, the bank may perform a first activation of the new credit card account for purposes of transactions implemented via a mobile wallet. Such an activation may be performed via the mobile wallet itself (i.e., the user does not need to take any action outside of the mobile wallet to have the new credit card account activated). For example, the user may be prompted with a message indicating that the credit card account has not yet been activated, and querying whether the user wishes to do so no (e.g., “Click ‘Yes’ to activate your new credit card for your mobile wallet”). For security purposes, the first activation does not activate the credit card for non-mobile wallet transactions involving use of the plastic credit card. Rather, the bank may also perform a second activation of the new credit card account for purposes of transactions implemented via a physical credit card associated with the new credit card account. Hence, the plastic credit card is not useable for credit card transactions until the second activation occurs. Such an arrangement ensures that the user is in possession of the physical credit card before the physical credit card is activated for purposes of transactions implemented via the physical credit card (e.g., a card-present transaction at a bricks and mortar merchant). 
     As will be appreciated, it may often take several days or more for a new physical credit card to be produced and delivered to the user after the user reports a previous credit card as having been lost or stolen. In the arrangement described herein, the credit card account may be activated for mobile wallet transactions much earlier, before the credit card is activated for the non-mobile wallet transactions involving use of the plastic credit card. For example, the credit card account may be activated one or more days before the user receives the plastic credit card, or even within one day of the bank receiving the report from the user that the plastic credit card has been lost or stolen. In some embodiments, the new credit card account may be activated for the mobile wallet within one hour or less of receiving the report from the user that the plastic credit card has been lost or stolen. 
     In other embodiments, when a credit card is reported as lost or stolen, the mobile wallet computer system  120  may permit the user to continue using the credit card number associated with the plastic credit card for mobile wallet transactions, but prevent the plastic credit card from being used for card-based transactions. When a physical credit card is lost or stolen, the physical credit card has been compromised. However, for purposes of the mobile wallet bank computer system  120 , the account number is simply an account identifier. So long as the mobile wallet has not been compromised, the mobile wallet computer system  120  can ensure the integrity of the transaction based on the fact that the user is in possession of the mobile device  110 , particularly in situations where at a point of sale a tokenized card number is used, anyway (e.g., as described above in connection with  FIG.  2   ). 
     Referring now to  FIG.  4    and  FIGS.  4 A- 4 D ,  FIG.  4    is a flow chart of a process  400  detailing a payment code generation process for an authenticated mobile wallet session, according to an example embodiment.  FIGS.  4 A- 4 D  are screens that may be displayed to the user during the process  400  of  FIG.  4    according to an example embodiment. Process  400  may be executed for a user requesting to execute a payment (e.g., transaction) with a merchant or other recipient  140 . Process  400  may be executed by a mobile wallet bank computer system  120  configured to manage the user mobile wallet account. 
       FIG.  4 A  shows a mobile banking screen that may be displayed to the user after the mobile wallet application has been installed on the mobile device  110 . Similar to  FIG.  3 B , the user is prompted in  FIG.  4 A  to provide full online banking login credentials (fields  323  and  325 ). By providing such credentials in fields  323  and  325 , the user may be provided with the full functionality of the online banking website. However, in  FIG.  4 A , the user is also provided with a second option, namely to provide mobile wallet login credentials (via selecting button  425 ). Hence, in  FIG.  4 A , the user is presented with two possible authentication paths, a first authentication path that prompts the user to provide online banking login credentials to gain access to online banking, and a second authentication path that prompts the user to provide mobile wallet login credentials to gain access to the mobile wallet. If the user selects the second authentication path, the user is delivered to the more payment-focused functionality of the mobile wallet. 
     Process  400  includes receiving a PIN from the user (step  402 ) to authenticate the user ( FIG.  4 B ). At step  402  the mobile wallet client application  116  prompts the user for a PIN that was used during the registration steps in process  300 . Hence, as previously indicated, the user may be authenticated based on the user&#39;s mobile wallet banking credentials (e.g., 4 digit PIN), rather than being prompted to provide the user&#39;s usual online banking authentication credentials (username and password). 
     In an alternative embodiment, a user may log into a mobile banking session with a source account bank computer system, or the user may directly access the mobile wallet bank computer system. Process  400  further includes allowing the user access to his or her mobile wallet account (step  404 ). For example, the user may access his or her mobile wallet account through his or her account at the source account bank computer system, or may log into his or her mobile wallet account at the mobile wallet bank computer system by providing a PIN or other identifier to the mobile wallet bank computer system. 
     Process  400  further includes validating the user based on the customer token and device token (step  406 ). When the user logs in to access his or her mobile wallet account, the customer token and device token stored on the mobile device (stored during step  310  of process  300 ) are provided to the mobile wallet bank computer system. The mobile wallet bank computer system validates the user and/or the mobile device for use with the mobile wallet account. Step  406  may further include validating the user based on the PIN or other identifier also provided to the mobile wallet bank computer system. For example, in order to be validated, the customer token, the device token, and the PIN may all need to match (i.e., be associated with each other in the mobile wallet computer system  120 ). As previously indicated, each user may have one customer token and one PIN which together are associated with multiple device tokens (such that the user can access the mobile wallet account from multiple devices). 
     Process  400  further includes generating a new device token (step  408 ), and sending the new device token to the mobile device of the user (step  410 ). Hence, in some embodiments, the device token may change each time the user uses the device. The device token may be a token that will identify the user and the associated mobile device to the mobile wallet bank computer system in the future. More particularly, the device token may identify a current session of the user. In other words, the token may be used to identify a particular function that the user may perform during the session, such as initiating a purchase. The token is encrypted by the mobile wallet bank computer system and provided to the mobile device. The mobile device stores the device token for future use. 
     Process  400  further includes receiving an indication that the user wishes to execute a payment or other transaction (step  412 ). Upon the indication, the mobile wallet bank computer system generates a code (e.g., a QR code) based on the user&#39;s default payment method (step  414 ) ( FIG.  4 C ). The QR code is generated including a combination of random digits and account information of the user. For example, the QR code may include the last four digits of a debit card or credit card number of an account associated with the user and the request. The account information may be used to identify a source account for the transaction at a later step in the transaction. The mobile wallet bank computer system  120  may use token information (e.g., customer token and device token information) from the mobile device to identify the mobile wallet account and associated source account to use in code generation. The code may provide credit card data or tokenized credit card data in Track 1 or Track 2 format, as described below with reference to  FIGS.  5 - 7   . The generated code is then provided as part of a payment token to the mobile device and/or to the merchant or other recipient of the payment or funds (step  416 ) ( FIG.  4 D ). 
     Referring to  FIGS.  5 - 6   , codes that may be sent during operation of the system  100  are shown. As previously indicated, information embedded in the codes may be embedded in a Track 1 format and Track 2. The code may be sent optically as a code or in another manner. As will be appreciated, the code formats shown in  FIGS.  5 - 6    are example code formats that may be used with the systems and methods described herein. In other embodiments, other formats may be used. 
     The Track 1 format in  FIG.  5    is shown to include 76 digits and the Track 2 format in  FIG.  6    is shown to include 38 digits. Each format may generally include a format code (digit 1), tokenized primary account number  501  (digits 2-20), a field separator (digit 21), an expiration date  505  (digits 35-38 in Track 1, digits 22-25 in Track 2), a service code (digits 39-41 or 26-28), and a payment token  507  (digits 42-76 or 29-38). Each track may additionally or alternatively include other fields representing different data to be embedded in the code. In one embodiment (the Track 1 format), the credit card data may include a customer name or other customer identifier (e.g., in digits 22-33 of the Track 1 format). 
     In various embodiments of the present disclosure, account information associated with the user&#39;s mobile wallet account may be represented in the code using digits 2 through 20 of the Track 1 or Track 2 format. This is shown in  FIGS.  5 - 6    as the tokenized primary account number (TPAN). Referring also to  FIG.  8   , the TPAN format is shown in greater detail. 
     As shown in  FIG.  7   , the first six digits of the TPAN may represent an issuer identification number (IIN) that is used to route the TPAN to the appropriate mobile wallet bank computer system  120 . The IIN is a predetermined number issued to each bank for financial institution for routing fund transfer requests. In the present configuration, an IIN that is associated with the bank that operates the mobile wallet computer system  120  may be used. 
     Digits 7 through 15 of the TPAN may represent a Trace ID, and digits 16 through 19 may represent account information (e.g., the last four digits of an actual account number, or other account information). First generating random numbers for digits 7 through 14 may create the Trace ID. The Trace ID may be used for verifying and approving a user initiated transaction. Once those digits are determined, then digit 15 may be calculated. Digit 15 is calculated such that digit 19 may be used as the checksum digit of the tokenized card number or the code. In other words, even though digit 19 is fixed (as part of the actual card number of the account), digit 19 may be used as the checksum digit, because digit 15 is calculated in such a way to allow the code to pass the error detection process. Digits 1-19 from  FIG.  7    map to digits 2-20 in  FIGS.  5  and  6   . For example, digits 2-20 of  FIGS.  5  and  6    may include the IIN, Trace ID, pseudo check digit, last 4 digits of the card number as shown in  FIG.  7   . 
     The checksum digit is used for error detection purposes (e.g., to detect errors in manually inputted data that is included in the code). For example, the checksum digit is used to help detect single digit errors, errors where digits are transposed, twin errors, etc. The checksum digit may then be used in one of several algorithms for checking for errors in the code. It should be appreciated that one of any type of checksum algorithm may be used with the embodiment described herein. 
     In other embodiments, a digit other than digit 15 may be used as the calculated digit. For example, any eight of the nine digits between digit 7 and 15 may be randomized, and the remaining digit may be used as the “checksum helper” digit (e.g., the digit calculated to make digit 19 the checksum digit). 
     Referring also to  FIG.  8   , actual card number is sent in Track 2 format that may be generated at step  810  is shown in greater detail. As compared to the QR code of  FIGS.  5 - 7   , the trace ID is moved to digits 26-33, and the actual account number may be provided as digits 2 through 17. In other words, a subset of the original token generated by the mobile wallet bank computer system is moved into a discretionary field of the new generated token. The code is shown to generally include the trace ID and account number, along with an expiration date field (e.g., with the same digits as determined in an earlier process of creating the original token) and a service code field. The code may optionally include any other type of information. 
     In various embodiments, using the trace ID may allow the financial institution to identify mobile wallet transactions. Upon identifying the mobile wallet transactions, the financial institution may segment the mobile wallet transactions for risk, customer service, security, and card not present transactions. In other embodiments, the transactions that were performed using mobile wallet bank computer system  120  each use a trace identification number and the user may be charged a different fee for such transactions. In various embodiments, when a user of a mobile wallet account loses their credit card or debit card and the financial institution issues the user a new credit card or debit card, the mobile wallet may be able to auto provision the newly issued cards. Auto provisioning may allow the user to use the mobile wallet account prior to receiving and/or activating the credit or debit card. In other embodiments, in the case of mobile wallet fraud, the mobile wallet account of the user may be reset. 
     A credit card may be used to pay for a transaction at a point of sale location using the physical credit card, known as a credit card present transaction. A credit card may be used when a credit card is not physically located at a merchant location, such as but not limited to, an online merchant transaction where the credit card information is entered in an online transaction. A financial institution may rank the risk of fraud for each type of transaction. In some embodiments, the financial institution may assign a higher risk rating to a credit card that is not present at the merchant location than a credit card present transaction. In various embodiments, a mobile wallet that performs a transaction at a merchant location may be considered more secure than a physical credit card because the mobile wallet does not provide the merchant the actual credit card number and the mobile wallet does not have the actual credit card number. Accordingly, the financial institution may determine that a transaction was a mobile wallet transaction based on the trace ID and rate the transaction to be more secure or fraud resistant than card present transaction. The financial institution may create a new risk rating that is of a lower risk for mobile wallet transactions. In some embodiments, the transactions that are performed using a mobile wallet may be charged different fee because of the risk rating. In various embodiments, due to the reduction of risk the mobile wallet transactions may be charged a lower fee than card present or card not present transactions. 
       FIG.  9    illustrates a process  900  that may be implemented by the system in  FIG.  1   . In various embodiments, process  900  may be used when an account holder reports their physical card lost or stolen via telephone, Internet, mobile device, etc. In some embodiments, process  900  may allow the account holder to perform one or more transactions using the mobile wallet stored on a mobile device, even after the physical card has been lost or stolen. Some advantages of process  900  may include the account retaining the use of the account even after the loss of a physical card. Additional advantages may include the account holder being able to activate the newly issued replacement card by using the mobile wallet functionality. 
     At step  903 , the financial institution computer system may receive a message from the user that the physical card is lost or stolen. In various embodiments, the account holder may contact the financial institution computer system using various communication methods, such as but not limited to, telephone, Internet, and mobile device. Upon receiving the message from the account holder that the physical card is lost or stolen, the financial institution computer system may ask the account holder whether the mobile wallet account has also been compromised. After receiving input from the account holder that the mobile wallet account holder has not been compromised, the financial institution computer system may deactivate the physical card account, at step  905 . In some embodiments, the financial institution computer system may assign the uncompromised mobile wallet account to a temporary account to allow the account holder to conduct transactions using the mobile wallet. 
     In various embodiments, the financial institution computer system may receive a request for a transaction from a merchant, at step  907 . At step  909 , the financial institution computer system determines whether the transaction is being performed by a mobile wallet or whether the transaction is being performed by the physical card information. Since the mobile wallet transaction is performed using at least a trace ID, the financial institution computer system may differentiate between the mobile wallet transaction and the physical card information transaction. 
     Upon determining that the transaction request is not from a mobile wallet or is using the actual card information, the financial institution computer system may deny the transaction request, at step  911 . The financial institution computer system would be able to avoid any fraudulent transactions using the actual card information by denying the transaction request that did not originate from a mobile wallet associated with the account. 
     When the financial institution computer system determines that the transaction request originated from a mobile wallet account, the financial institution may determine whether a new replacement card number has been issued to the account holder at step  913 . If a new replacement card number has not been issued, the financial institution may approve the transaction at step  915  based on the determination that the transaction is a mobile wallet transaction and based on the fact that the mobile wallet account has not been compromised. In some embodiments, the transaction may be approved using the temporary card number discussed above. 
     In various embodiments, when the financial institution has issued a new card, but account holder has not activated the physical card because the account holder has not received the card or other reasons, the financial institution may update its records with respect to the mobile wallet. For example, at step  917 , the financial institution computer system may update its records to associate the new card number with the mobile wallet account of the previous card number at step  917 . After step  917 , the financial institution may send an approval for the transaction request at step  919 . In other embodiments, the mobile wallet client application on the mobile device  110  may prompt the user to activate the card prior to the user having received the physical card. In other embodiments, even after receiving the card the account holder may wish to activate the card via the mobile wallet application. Activating the card by the account holder, may update the financial institution settings to associate the new card number with the mobile wallet account number. 
       FIG.  10    illustrates a payment process that may be implemented by the system in  FIG.  1    according to an example embodiment. Except as otherwise described below, the payment process of  FIG.  10    is the same as the payment process of  FIG.  2   . Hence, the above discussion with respect to  FIG.  2    applies to  FIG.  10    as well, except as otherwise described below. 
     In the embodiment of  FIG.  10   , rather than providing the substitute card number to the mobile wallet computer system  120  (as in  FIG.  2   ), the acquirer processor computer system  145  provides the substitute card number to a card network computer system  152 . Hence, a tokenized card number may be generated and ultimately delivered to the acquirer processor computer system  145  at steps  1001 ,  1003 ,  1005 ,  1007  in the manner described above in connection with steps  201 ,  203 ,  205 ,  207 . 
     Next, at step  1009 , the acquirer processor computer system  145  sends the tokenized card number to the card network computer system  152 . Next, at step  1011 , the card network computer system  152  sends the tokenized card number to the mobile wallet bank computer system  120 . After receiving the request from the card network computer system  152 , the mobile wallet bank computer system  120  may determine the actual card number and send the actual card number back to the acquirer processor at step  1012 . In one embodiment, the determination of the actual card number may occur by searching for the account information associated with the payment token and/or trace ID within the tokenized card number. Additionally, the trace ID from the tokenized card number may be sent with the actual card number at step  1012 , similar to step  211 . Again, at this point, the issuer discretionary field is no longer needed for the payment token, hence, the trace ID may be sent to the acquirer processor computer system  145  in the issuer discretionary field. 
     At step  1013 , the card network computer system  152  sends the actual card number and the trace ID to the source account computer system  130  for processing a payment. The source account bank computer  130  may retrieve the trace ID that was received from the mobile wallet bank computer system  120  by searching for the actual card number that was received from the payment system  150 . The source account bank computer  130  may compare the trace ID that was received/stored at step  1003  with the trace ID that was received from the payment system  150  at step  1013 . Assuming there is a match, the source account bank computer  130  may issue an approval for the transaction. After verifying the actual card number and the trace ID in the issuer discretionary field, the source account bank computer system  130  may send an approval to the payment system  150  at step  1015 . Steps  1017 ,  1019 , and  1021  may be performed in the same manner as discussed above in connection with steps  217 ,  219 , and  221 . 
     As discussed above in connection with  FIG.  2   , the use of the payment token and trace ID as described herein allows for two levels of authentication. The payment token is generated by the mobile wallet computer system at step  1002 . The payment token is then transmitted to the mobile device  110 , then to the merchant computer system  140 , then to the acquirer processor computer system  145 , then to the card network computer system  152 , and eventually back to the mobile wallet computer system  120  where it is matched with the original payment token generated at step  1002 . Similarly, the Trace ID is also generated by the mobile wallet computer system at step  1002 , and then transmitted to the mobile device  110 , then to the merchant computer system  140 , then to the acquirer processor computer system  145 , then to the card network computer system  152 , and eventually back to the mobile wallet computer system  120  where it is matched with the Trace ID generated at step  1002 . In the case of the Trace ID, however, the Trace ID is then further transmitted back to the payment system  150 , and then to the source account computer system  130  where it is matched with the Trace ID generated at step  1002 . Accordingly, the trace ID used in conjunction with the tokenized credit card number allows both the mobile wallet bank computer system  140  and the source account bank computer system  130  to authenticate the transaction. Using the trace ID in the above described manner may permit the source account bank computer system  130  and the mobile wallet bank computer system  120  to verify the trace ID at least twice prior to approving a transaction and transferring funds. Further, as previously discussed, the trace ID may be used by the source account computer system  130  to determine whether the credit card transaction was a mobile wallet transaction (e.g., as opposed to an in-person card-present transaction involving use of the user&#39;s physical credit card, as opposed to an online transaction, and so on). In other embodiments, the mobile wallet computer system  120  generates a tokenized card number, but does not embed a trace ID in the tokenized card number. 
     In some embodiments, instead of embedding the trace ID in a tokenized credit card account number at step  1002 , the actual credit card number is transmitted to the mobile device  110  and the merchant computer system  140 . In such an embodiment, the trace ID may be included in the issuer discretionary field at step  1002 , and the payment token may be communicated in another manner or another payment matching mechanism may be used. The trace ID may be stored in the issuer discretionary field and may travel though the payment processing system, until it is verified by the source account bank computer system  130 . After being verified by the source account bank computer system  130 , the transaction may be approved and the funds may be transferred from the source account bank computer system to the acquirer processor computer system  145 . In other embodiments, the same financial institution may own the source account bank computer system  130  and the mobile wallet bank computer system  120 . Hence, as previously described in connection with the discussion of  FIG.  2   , the tokenized card account number and trace ID features may each be used alone or in combination with each other. 
     The present disclosure contemplates methods, systems and program products on any machine-readable media for accomplishing various operations. The embodiments of the present disclosure may be implemented using existing computer processors, or by a special purpose computer processor for an appropriate system, incorporated for this or another purpose, or by a hardwired system. Embodiments within the scope of the present disclosure include program products comprising machine-readable media for carrying or having machine-executable instructions or data structures stored thereon. Such machine-readable media can be any available media that can be accessed by a general purpose or special purpose computer or other machine with a processor. By way of example, such machine-readable media can comprise RAM, ROM, EPROM, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to carry or store desired program code in the form of machine-executable instructions or data structures and which can be accessed by a general purpose or special purpose computer or other machine with a processor. Combinations of the above are also included within the scope of machine-readable media. Machine-executable instructions include, for example, instructions and data which cause a general purpose computer, special purpose computer, or special purpose processing machines to perform a certain function or group of functions. Software implementations could be accomplished with standard programming techniques with rule based logic and other logic to accomplish the various connection steps, processing steps, comparison steps and decision steps. 
     While this specification contains many specific implementation details, these should not be construed as limitations on the scope of what may be claimed, but rather as descriptions of features specific to particular implementations. Certain features described in this specification in the context of separate implementations can also be implemented in combination in a single implementation. Conversely, various features described in the context of a single implementation can also be implemented in multiple implementations separately or in any suitable subcombination. Moreover, although features may be described above as acting in certain combinations and even initially claimed as such, one or more features from a claimed combination can in some cases be excised from the combination, and the claimed combination may be directed to a subcombination or variation of a subcombination. 
     Similarly, while operations are depicted in the drawings in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed, to achieve desirable results. In certain circumstances, multitasking and parallel processing may be advantageous. Moreover, the separation of various system components in the implementations described above should not be understood as requiring such separation in all implementations, and it should be understood that the described program components and systems can generally be integrated in a single software product or packaged into multiple software products embodied on tangible media. 
     Thus, particular implementations of the subject matter have been described. Other implementations are within the scope of the following claims. In some cases, the actions recited in the claims can be performed in a different order and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In certain implementations, multitasking and parallel processing may be advantageous. 
     The claims should not be read as limited to the described order or elements unless stated to that effect. It should be understood that various changes in form and detail may be made by one of ordinary skill in the art without departing from the spirit and scope of the appended claims. All implementations that come within the spirit and scope of the following claims and equivalents thereto are claimed.
