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

receiving an account identifier corresponding to the another 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 another 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 another transaction card account, and

the load amount loaded to the transaction card account;

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

3. 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.

4. The method of claim 1 , further comprising:

storing, 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.

5. The method of claim 1 , wherein the first contactless reader comprises a Near Field Communications (NFC) integrated circuit (IC).

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

7. The method of claim 6 , wherein the contactless transceiver comprises a Near Field Communications (NFC) integrated circuit (IC).

8. 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.

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

a mobile device comprising a processor; a contactless reader operatively coupled to the processor; and a memory storing a plurality of instructions, which when executed by the processor causes the processor 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 of the mobile device;

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

receive an account identifier corresponding to the another 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 mobile device is configured to use at least a partial amount of the load amount to repay the amount owing to the another transaction card account.

10. The system of claim 9 , wherein the mobile device is further configured to:

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

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

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

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

11. The system of claim 9 , 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.

12. The system of claim 9 , wherein the first mobile device 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 first transaction card account.

13. The system of claim 9 , wherein the contactless receiver comprises a Near Field Communications (NFC) integrated circuit (IC).

14. The system of claim 9 , wherein the another mobile device comprises a contactless transceiver, and wherein the acknowledgement is received, and the account identifier is transmitted, via the contactless transceiver.

15. The system of claim 14 , wherein the contactless transceiver comprises a Near Field Communications (NFC) integrated circuit (IC).

16. The system of claim 9 , wherein the load amount is less than the amount owing, and the amount owing is reduced by the load amount.
