Abstract

The present invention provides a method for conducting a transaction that includes receiving a pseudo account identifier that corresponds to a primary account identifier. The pseudo account identifier may be received at a portable wireless device and may be generated by a remote server computer. The portable wireless device can receive the pseudo account identifier over a first network and provide the pseudo account identifier to an access device. The access devices generally comprises a reader that can receive the pseudo account identifier, and thereafter send a message to request authorization of a transaction. The authorization request message may include the pseudo account identifier and is sent to a payment processing network. The authorization request message is sent to the payment processing network over a second network. The payment processing network may then process the authorization message and return a response that indicates if the transaction is authorized or not.

Claims

1. A method of conducting a transaction comprising:

receiving a pseudo account identifier that corresponds to a consumer'"'"'s account identifier at a portable wireless device, wherein the pseudo account identifier was previously generated by a remote server computer and was previously sent over a first network; and

providing the pseudo account identifier to an access device comprising a reader, wherein the reader thereafter sends an authorization request message comprising the pseudo account identifier to a payment processing network over a second network, wherein the consumer thereafter receives an authorization response message, wherein the authorization response message indicates if the transaction is approved or not approved.

2. The method of claim 1 wherein the authorization response message is printed on a receipt that is generated by the access device, and the consumer receives the authorization response message by receiving the receipt.

3. The method of claim 1 wherein the authorization response message was sent to the consumer over the first network.

4. The method of claim 1 wherein the first network is a communications network and the second network is a transaction processing network.

5. The method of claim 1 wherein the account identifier is a primary account number and wherein the pseudo account identifier is a pseudo account number.

6. The method of claim 1 wherein the access device comprises a contactless reader.

7. The method of claim 1 wherein the payment processing network converts the pseudo account identifier into the corresponding account identifier.

8. A method comprising:

receiving a request for a pseudo account identifier corresponding to a first account identifier, wherein said request is received over a first network;

generating a pseudo account identifier corresponding to the first account identifier; and

sending the generated pseudo account identifier to a portable wireless device over the first network, wherein the portable wireless device is thereafter capable of performing one or more transactions by providing the pseudo account identifier to an access device.

9. The method of claim 8 further comprising storing the generated pseudo account identifier and its corresponding first account identifier.

10. The method of claim 8 further comprising receiving the pseudo account identifier over a second network, wherein the first account identifier is generated using the pseudo account identifier.

11. The method of claim 10, wherein the first network is a communications network and the second network is a transaction processing network.

12. A method comprising:

receiving a pseudo primary account identifier from a portable wireless device, wherein said pseudo primary account identifier corresponds to a primary account identifier;

sending a transaction authorization request comprising the pseudo primary account identifier to a payment processing network, wherein the pseudo primary account identifier is thereafter converted to the primary account identifier, wherein the transaction authorization request is processed to approve or deny the transaction; and

receiving an authorization response message, wherein the authorization response message indicates if the transaction is approved or not approved.

13. The method of claim 12 wherein the transaction authorization request is sent to the payment processing network over a transaction processing network.

14. The method of claim 12 further comprising printing a receipt that indicates if the transaction is approved or not approved.

15. The method of claim 12 wherein the pseudo account identifier is received by an access device comprising a contactless reader.

16. A portable wireless device for performing proximity transactions comprising:

a long range wireless communication element;

a short range communication element

a processor coupled to the long range wireless communication element and the short range communication element;

a memory coupled to the processor, the memory comprising computer code for receiving a pseudo account identifier that corresponds to a primary account identifier, wherein the pseudo account identifier is generated by a remote server computer and was sent over a first network and is received by the portable wireless device using the long range communication element, computer code for providing the pseudo account identifier to an access device comprising a reader using the short range communication element, and computer code for storing at least one primary account identifier.

17. The portable wireless device of claim 16 further comprising a user interface module, wherein the user interface module allows the user to select one of the at least one primary account identifiers.

18. The portable wireless device of claim 16 wherein the memory coupled to the processor further comprises computer code for enabling and disabling the device.

19. The portable wireless device of claim 16 wherein the memory coupled to the processor further comprises computer code for selecting a primary account identifier to be used for a transaction.

20. The portable wireless device of claim 16 wherein the portable wireless device is a cellular phone.

21. The portable wireless device of claim 16 wherein the short range communications element is an RF communications element.

22. A method of conducting a transaction comprising:

generating a pseudo account identifier that corresponds to a consumer'"'"'s account identifier at a portable wireless device, wherein the pseudo account identifier is sent to a remote server computer and is sent over a first network; and

providing the pseudo account identifier to an access device comprising a reader, wherein the reader thereafter sends an authorization request message comprising the pseudo account identifier to a payment processing network over a second network, wherein the consumer thereafter receives an authorization response message, wherein the authorization response message indicates if the transaction is approved or not approved.

23. A method comprising:

receiving a pseudo account identifier corresponding to a first account identifier, wherein the pseudo account identifier is received over a first network;

storing the pseudo account identifier corresponding to the first account identifier; and

sending a receipt acknowledgment to a portable wireless device over the first network, wherein the portable wireless device is thereafter capable of performing one or more transactions by providing the pseudo account identifier to an access device.

24. A portable wireless device for performing proximity transactions comprising:

a long range wireless communication element;

a short range communication element

a processor coupled to the long range wireless communication element and the short range communication element;

a memory coupled to the processor, the memory comprising computer code for generating a pseudo account identifier that corresponds to a primary account identifier, wherein the pseudo account identifier is sent to a remote server computer over a first network by the portable wireless device using the long range communication element, computer code for providing the pseudo account identifier to an access device comprising a reader using the short range communication element, and computer code for storing at least one primary account identifier.
