System and method of loading a transaction card and processing repayment on a mobile device

1. A method of loading a transaction card account onto a mobile device, the mobile device comprising a memory and a contactless reader, the method comprising:

reading, via the contactless reader, transaction card information from a physical contactless transaction card corresponding to the transaction card account;

sending a retrieval message, to an issuer server, to retrieve a card security credential for the transaction card account, the retrieval message comprising the transaction card information for identifying the transaction card account at the issuer server;

receiving, from the issuer server, a card security credential for the transaction card account;

storing,

the transaction card information; and

the card security credential;

as a transaction card corresponding to the transaction card account on the memory of the mobile device;

transmitting to a recipient mobile device an acknowledgement that acknowledges an amount owing to a recipient transaction card account associated with the recipient mobile device;

receiving an account identifier corresponding to the recipient transaction card account; and

receiving a load amount to be loaded to the transaction card account, wherein, prior to adding the load amount to the transaction card account, the mobile device is configured to use at least a partial amount of the load amount to repay the amount owing to the recipient transaction card account.

2. The method of claim 1 comprises: transmitting a repayment message to an e-wallet server, the repayment message comprising:

the received account identifier corresponding to the recipient transaction card account, and

the load amount loaded to the transaction card account;

wherein the e-wallet server is configured to identify the recipient transaction card account from the received account identifier and add at least a partial amount of the load amount to the recipient transaction card account.

3. The method of claim 1 , further comprising:

receiving at the recipient mobile device, from the mobile device, the acknowledgement that acknowledges the amount owing; and

transmitting, from the recipient mobile device to the mobile device, the account identifier corresponding to the recipient transaction card account.

4. The method of claim 1 , wherein the load amount is greater than the amount owing, and a remaining amount of the load amount not used to repay the amount owing is added to the transaction card account.

5. The method of claim 1 , wherein the load amount is less than the amount owing, and the amount owing is reduced by the load amount.

6. The method of claim 1 , further comprising:

storing a payment queue associated with the transaction card account, wherein the payment queue comprises a plurality of amounts owing from the transaction card account.

7. The method of claim 1 , wherein the mobile device comprises a contactless transceiver, and wherein the acknowledgement is transmitted, and the account identifier is received, via the contactless transceiver.

8. The method of claim 7 , wherein the contactless transceiver comprises a Near Field Communications (NFC) integrated circuit (IC).

9. The method of claim 1 , wherein the recipient mobile device comprises a recipient contactless transceiver, and wherein the acknowledgement is received, and the account identifier is transmitted, via the recipient contactless transceiver.

10. The method of claim 9 , wherein the recipient contactless transceiver comprises a Near Field Communications (NFC) integrated circuit (IC).

11. A system for loading a transaction card account, the system comprising:

a memory;

a contactless reader;

a processor operable to:

read, via the contactless reader, transaction card information from a physical contactless transaction card corresponding to the transaction card account;

send a retrieval message, to an issuer server, to retrieve a card security credential for the transaction card account, the retrieval message comprising the transaction card information for identifying the transaction card account at the issuer server;

receive, from the issuer server, a card security credential for the transaction card account;

store the transaction card information and the card security credential as a transaction card corresponding to the transaction card account on the memory;

transmit to a recipient mobile device an acknowledgement that acknowledges an amount owing to a recipient transaction card account associated with the recipient mobile device;

receive an account identifier corresponding to the recipient transaction card account; and

receive a load amount to be loaded to the transaction card account, wherein, prior to adding the load amount to the transaction card account, the processor is configured to use at least a partial amount of the load amount to repay the amount owing to the recipient transaction card account.

12. The system of claim 11 , wherein the processor is further configured to:

transmit to an e-wallet server, a repayment message comprising

the received account identifier corresponding to the recipient transaction card account, and

the load amount for repaying the amount owing to the recipient transaction card account;

wherein the e-wallet server is configured to identify the recipient transaction card account from the received account identifier and add at least a partial amount of the load amount to the recipient transaction card account.

13. The system of claim 11 , wherein the processor is configured to, when the load amount is greater than the amount owing, add a remaining amount of the load amount not used to repay the amount owing to the transaction card account.

14. The system of claim 11 , wherein the processor is configured to, when the load amount is less than the amount owing, reduce the amount owing by the load amount.

15. The system of claim 11 , wherein the processor is further configured to:

store, on the memory, a payment queue associated with the transaction card account, wherein the payment queue comprises a plurality of amounts owing from the transaction card account.

16. The system of claim 11 , wherein the contactless reader comprises a contactless transceiver to transmit the acknowledgement and receive the account identifier.

17. The system of claim 16 , wherein the contactless transceiver comprises a Near Field Communications (NFC) integrated circuit (IC).

18. The system of claim 11 , wherein the recipient mobile device comprises a recipient contactless transceiver, and wherein the acknowledgement is received, and the account identifier is transmitted, via the recipient contactless transceiver.

19. The system of claim 18 , wherein the recipient contactless transceiver comprises a Near Field Communications (NFC) integrated circuit (IC).
