In an exemplary embodiment of the invention, an authorized sample receiver (ASR) comprises a processor that is configured to verify biometric sample data in order to create registered biometric sample data. The ASR may also comprise a communications device configured to receive a transaction request from an RF transaction device, wherein the transaction request comprises transaction biometric sample data, a reload protocol update request, and an RF device identification code. The ASR may also be configured to authorize the transaction request in response to the transaction biometric sample data substantially matching the registered biometric sample data. The ASR may further comprise a reload protocol data file associated with the device identification code, and the reload protocol data file may be configured to be updated in accordance with the reload protocol update request.
