The portable device sends the purchase amount to a display.
Claims20
A method, comprising:
- encrypting, by a portable device, a first message using a first encryption key, wherein the first message comprises a request to get first information related to a financial account from a server;
- generating, by the portable device, a second message by encrypting the encrypted first message using a third encryption key, wherein the encrypted first message is mapped to a first non-guaranteed bit rated (GBR) bearer;
- transmitting, by the portable device, the second message via the first non-GBR bearer;
- receiving, by the portable device, a third message via a second non-GBR bearer, wherein the third message comprises the first information related to the financial account;
- decrypting, by the portable device, the third message using a second decryption key;
- decrypting, by the portable device, the decrypted third message using a fourth decryption key;
- displaying, by the portable device, at least a portion of the first information related to the financial account;
- receiving, by the portable device, a request message via a near field connection (NFC) interface to get second information related to the financial account from a merchant machine;
- transmitting, by the portable device, a response message via the NFC interface to the merchant machine, wherein the response message comprises the second information related to the financial account;
- triggering, by the merchant machine, a financial debit from the financial account after receiving the response message;
- and
- receiving, by the portable device, a fourth message, wherein the fourth message comprises updated account information related to the financial account.
