Payment Channel Returning Limited Use Proxy Dynamic Value

Abstract

A central platform provides proxy dynamic values for any one of a number of a cardholder's portable payment devices, upon a request for such information made during a transaction. The proxy dynamic value can be provided to the merchant, who then can route it into the acceptance network in order to initiate the authentication process. The central platform provides the actual primary account number associated with the proxy dynamic value during the authentication process.

         21 . A method for facilitating a mobile transaction, the method comprising:
 in response to initiation of the mobile transaction by a user using a merchant application provided in, and executing on, a mobile device, receiving by a computer system, a request to obtain a proxy dynamic value that is to be associated with the mobile transaction from the mobile device;   responsive to the computer system authenticating the user, providing to the mobile device, a list of portable payment devices the user has enrolled with the computer system;   receiving, by the computer system, a selection of a portable payment device from the list of portable payment devices from the mobile device;   generating and associating by the computer system, the proxy dynamic value associated with the mobile transaction, the proxy dynamic value being distinct from and corresponding to a primary account number (PAN) of the portable payment device;   transmitting, by the computer system, the proxy dynamic value to the mobile device, wherein the mobile device further transmits the proxy dynamic value to a merchant server;   receiving, by the computer system, the proxy dynamic value from the merchant server; and   processing by the computer system, the mobile transaction based on obtaining the primary account number associated with the proxy dynamic value.   
     
     
         22 . The method of  claim 21 , wherein the computer system receives the request to obtain the proxy dynamic value from an application executed on the mobile device. 
     
     
         23 . The method of  claim 21 , wherein the computer system transmits the proxy dynamic value to an application executed on the mobile device, and wherein the application further transmits the proxy dynamic value to the merchant application executed on the mobile device. 
     
     
         24 . The method of  claim 23 , wherein the merchant application executed on the mobile device transmits the proxy dynamic value to the merchant server. 
     
     
         25 . The method of  claim 21 , wherein the proxy dynamic value is in a similar format as the primary account number. 
     
     
         26 . The method of  claim 21 , wherein the proxy dynamic value is valid during a single mobile transaction. 
     
     
         27 . The method of  claim 21 , wherein the computer system receives the proxy dynamic value from the merchant server via an acquirer computer of an acquirer associated with the merchant server. 
     
     
         28 . The method of  claim 21 , wherein the list of portable payment devices include one or more of credit cards, debit cards, or pre-paid cards. 
     
     
         29 . The method of  claim 21 , wherein the computer system authenticates the user based on a cryptogram generated by the mobile device, the cryptogram being generated by a secret key provided to the mobile device by the computer system. 
     
     
         30 . The method of  claim 21 , wherein the computer system is distinct from an issuer computer and distinct from an acquirer computer. 
     
     
         31 . The method of  claim 21 , wherein the mobile transaction is conducted during an online purchase with a merchant using the merchant application that is executed on the mobile device. 
     
     
         32 . A computer system comprising;
 a processor; and   a computer readable medium coupled to the processor, the computer readable medium comprising code, executable by the processor to implement a method comprising
 in response to initiation of a mobile transaction by a user using a merchant application provided in, and executing on, a mobile device, receiving a request to obtain a proxy dynamic value that is to be associated with the mobile transaction from the mobile device; 
 providing to the mobile device, a list of portable payment devices the user has enrolled with the computer system; 
 receiving a selection of a portable payment device from the list of portable payment devices from the mobile device; 
 generating and associating the proxy dynamic value associated with the mobile transaction, the proxy dynamic value being distinct from and corresponding to a primary account number (PAN) of the portable payment device; 
 transmitting the proxy dynamic value to the mobile device, wherein the mobile device further transmits the proxy dynamic value to a merchant server; 
 receiving the proxy dynamic value from the merchant server; and 
 processing the mobile transaction based on obtaining the primary account number associated with the proxy dynamic value. 
   
     
     
         33 . The computer system of  claim 32 , wherein the computer system receives the request to obtain the proxy dynamic value from an application executed on the mobile device. 
     
     
         34 . The computer system of  claim 32 , wherein the computer system transmits the proxy dynamic value to an application executed on the mobile device, and wherein the application further transmits the proxy dynamic value to the merchant application executed on the mobile device. 
     
     
         35 . The computer system of  claim 32 , wherein the proxy dynamic value is in a similar format as the primary account number. 
     
     
         36 . The computer system of  claim 32 , wherein the computer system receives a transaction report of the mobile transaction from the merchant server. 
     
     
         37 . The computer system of  claim 32 , wherein the computer system is distinct from an issuer computer and distinct from an acquirer computer. 
     
     
         38 . The computer system of  claim 32 , wherein the proxy dynamic value is valid during a single mobile transaction. 
     
     
         39 . The computer system of  claim 32 , wherein the computer system receives the proxy dynamic value from the merchant server via an acquirer computer of an acquirer associated with the merchant server. 
     
     
         40 . The computer system of  claim 32 , wherein the list of portable payment devices include one or more of credit cards, debit cards, or pre-paid cards.
