Abstract

A portable consumer device may have money stored therein, which can be calculated using an accumulator record. The accumulator record can be incremented by the amount of any transaction using the portable consumer device. The accumulator record can retain the value of the prior transactions, upon additional funds being collected on the portable consumer device.

Claims

1. A portable consumer device comprising:

a communications element configured to communicate with an access device during one or more transactions; and

a memory element, the memory element including an accumulator record, wherein the accumulator record retains the value of the one or more transactions upon additional funds being collected on the portable consumer device.

2. The portable consumer device of claim 1, wherein the memory element further comprises a limit amount, wherein the difference between the limit amount and the accumulator record comprises an offline balance amount for the portable consumer device.

3. The portable consumer device of claim 2, wherein the memory element further comprises an offline balance amount, the portable consumer device further comprising a processor, the processor configured to determine the offline balance amount.

4. The portable consumer device of claim 1, wherein the communications element comprises one of a wireless antenna or a contact interface.

5. The portable consumer device of claim 1, wherein the portable consumer device comprises a wireless phone.

6. The portable consumer device of claim 1, wherein the portable consumer device comprises a smart card.

7. A method for processing a transaction with a portable consumer device, the transaction having a value, the method comprising:

determining, using a processor, the value of an accumulator record stored in a memory of the portable consumer device;

incrementing, using the processor, the accumulator record by the value of the transaction, wherein the accumulator record retains the value of the transaction upon additional funds being collected on the portable consumer device.

8. The method of claim 7, wherein the steps of the method are performed by the portable consumer device.

9. The method of claim 7, wherein the steps of the method are performed by an access device.

10. The method of claim 7, further comprising:

determining, using the processor, a value of a limit amount stored in a memory of the portable consumer device;

identifying an issuer associated with the portable consumer device;

sending an authorization request message for the transaction to the issuer, the authorization request message including the value of the limit amount and the value of the accumulator record;

receiving an authorization response message from the issuer, wherein the authorization response message includes an amount of additional funds to be collected on the portable consumer device; and

incrementing the limit value for the portable consumer device by the amount of additional funds.

11. The method of claim 10, further comprising, prior to sending the authorization request message, determining the offline balance of the portable consumer device.

12. The method of claim 11, wherein determining the offline balance of the portable consumer device is performed by the portable consumer device.

13. A computer readable medium for managing a portable consumer device, the computer readable medium comprising:

code for maintaining a shadow account for the portable consumer device, the shadow account comprising

a shadow accumulator record, wherein the shadow accumulator record retains the value for each transaction in the portable device transaction history, upon additional funds being collected on the portable consumer device.

14. The computer readable medium of claim 13, wherein the shadow account further comprises a shadow limit amount, the shadow limit amount comprising a value.

15. The computer readable medium of claim 14, further comprising

code for storing the value of host funds for an account associated with a portable consumer device;

code for adding the value of the host funds to the shadow limit amount; and

code for replacing the value of a limit amount on the portable consumer device with the value of the shadow limit amount.

16. The computer readable medium of claim 13, further comprising:

code for determining the value of an accumulator record for the portable consumer device; and

code for replacing the value of the shadow accumulator record with the value of the accumulator record for the portable consumer device.

17. The computer readable medium of claim 14, further comprising:

code for receiving an authorization request message for a transaction involving the portable consumer device, wherein the authorization request message includes a limit amount for the portable consumer device;

code for reviewing the authorization request message;

code for sending an authorization response message, wherein the authorization response message includes a replacement value for the limit amount on the portable consumer device.

18. The computer readable medium of claim 17, wherein, prior to sending the authorization response message, the replacement value is greater than the value of the limit amount on the portable consumer device.

19. The computer readable medium of claim 17, wherein the replacement value comprises the shadow limit amount.

20. The computer readable medium of claim 17, wherein the authorization response message includes an accumulator record for the portable consumer device, wherein the shadow account includes a shadow account balance, further wherein the replacement value comprises the shadow account balance plus the accumulator record.
