Funding a radio frequency device transaction
A transponder-reader payment system includes an RFID reader for interrogating a transponder and an RFID transponder device. The RFID reader receives, from the RFID transponder device, a code that is associated with a first funding source and a second funding source. The RFID reader communicates a request associated with a transaction to a payment processor. The request includes the code and the transaction is funded using the first funding source and the second funding source associated with the code. In one embodiment, the transaction is funded according to a funding account protocol associated with the code.
1. A Radio Frequency (RF) customer payment device, comprising:
an RF transponder configured to receive a customer payment device authentication value from an RF identification (RFID) reader, wherein the customer payment device authentication value is a random number generated by the RFID reader;
a database comprising a unique customer payment device identification code, a unique customer payment device encryption key corresponding to the unique customer payment device identification code, and a customer payment device account code;
a biometric sensor configured to detect a proffered biometric sample to create biometric sample data; and
a customer payment device authentication circuit to communicate with the database, wherein the customer payment device authentication circuit is configured to create a device authentication code using the customer payment device authentication value and the encryption key;
wherein the RF transponder is configured to transmit the device authentication code to the RFID reader, and wherein the customer payment device authentication circuit is configured to be enabled in response to the biometric sample data matching authenticated biometric sample data.
2. The RF customer payment device of claim 1 , wherein the customer payment device account code comprises a unique account number in a magnetic stripe format.
3. The RF customer payment device of claim 1 , wherein the proffered biometric sample comprises a biometric sample characteristic including fingerprints.
