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.

Claims

1. A method for conducting a payment transaction between a cardholder and a merchant comprising:

in response to initiation of the payment transaction by the cardholder, receiving, at a computer system, a request to obtain a proxy dynamic value from a merchant computer associated with a merchant, the computer system being distinct from an issuing bank and distinct from an acquiring bank;

in response to receiving the request to obtain the proxy dynamic value from the merchant computer, presenting, by the computer system to a cardholder communication device, the cardholder with a list of portable payment devices the cardholder has enrolled with the computer system;

receiving, a selection of a portable payment device from the list of portable payment devices, from the cardholder communication device;

generating and associating, by the computer system, a proxy dynamic value which is distinct from and corresponds to a primary account number (PAN) of the portable payment device; and

providing, by the computer system, the proxy dynamic value to the merchant computer;

receiving, by the computer system, the proxy dynamic value after the merchant computer receives the proxy dynamic value; and

returning, by the computer system, the primary account number,

wherein the primary account number is used to complete the payment transaction.

2. The method of claim 1 wherein the proxy dynamic value is received from an acquiring bank of the merchant, and the primary account number is returned to the acquiring bank, wherein conclusion of the payment transaction includes the acquiring bank sending the corresponding PAN to an issuing bank of the cardholder.

3. The method of claim 1 wherein the proxy dynamic value is formatted as the primary account number.

4. The method of claim 1 wherein the portable payment devices include one or more of credit cards, debit cards, or pre-paid cards.

5. The method of claim 1, wherein the generated proxy dynamic value is valid during a single payment transaction.

6. The method of claim 1, wherein a new proxy dynamic value is generated responsive to each payment transaction with the portable payment device.

7. The method of claim 1, further comprising:

after receiving the proxy dynamic value, determining, by the computer system, the primary account number based at least in part on the proxy dynamic value.

8. The method of claim 1, wherein:

the cardholder provides a user identifier distinct from the PAN and distinct from the proxy dynamic value to the merchant computer during initiation of the payment transaction;

the merchant computer provides the user identifier to the computer system as part of the request for the proxy dynamic value; and

the computer system associates the generated proxy dynamic value with the PAN based at least in part on the user identifier.

9. The method of claim 8, wherein the payment transaction is initiated from a mobile phone having an associated mobile phone number and the user identifier comprises the mobile phone number.

10. The method of claim 1, wherein the proxy dynamic value is newly generated by the computer system in response to receiving the request for the proxy dynamic value from the merchant computer.

11. The method of claim 1 wherein

receiving, by the computer system, the proxy dynamic value after the merchant computer receives the proxy dynamic value comprises receiving, by the computer system, the proxy dynamic value from a payment processing network after the merchant computer receives the proxy dynamic value;

and

returning, by the computer system, the primary account number comprises returning, by the computer system, the primary account number to the payment processing network.

12. The method of claim 11 wherein the payment processing network forwards the primary account number to an issuer computer associated an issuer of the primary account number after the payment processing network receives the primary account number.

13. 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 payment transaction by a cardholder, receiving, at the computer system, a request to obtain a proxy dynamic value from a merchant computer associated with a merchant, the computer system being distinct from an issuing bank and distinct from an acquiring bank;

in response to receiving the request to obtain the proxy dynamic value from the computer system of the merchant, presenting, by the computer system to a cardholder communication device, the cardholder with a list of portable payment devices the cardholder has enrolled with the computer system;

receiving, a selection of a portable payment device from the list of portable payment devices, from the cardholder communication device;

generating and associating, by the computer system, a proxy dynamic value which is distinct from and corresponds to a primary account number (PAN) of the portable payment device; and

providing, by the computer system, the proxy dynamic value to the merchant computer;

receiving, by the computer system, the proxy dynamic value after the merchant computer receives the proxy dynamic value; and

returning, by the computer system, the primary account number,

wherein the primary account number is used to complete the payment transaction.

14. The computer system of claim 13, wherein the proxy dynamic value is formatted as the primary account number.

15. The computer system of claim 13, wherein the method further comprises

receiving, by the computer system, the proxy dynamic value after the merchant computer receives the proxy dynamic value comprises receiving, by the computer system, the proxy dynamic value from a payment processing network after the merchant computer receives the proxy dynamic value, and

returning, by the computer system, the primary account number comprises returning, by the computer system, the primary account number to the payment processing network.

16. The computer system of claim 15 wherein the payment processing network forwards the primary account number to an issuer computer associated an issuer of the primary account number after the payment processing network receives the primary account number.

17. A transaction processing system comprising:

the computer system of claim 13; and

a merchant computer in communication with the computer system.

18. The transaction processing system of claim 17 further comprising:

the cardholder communication device.
