Abstract

A system and method for securing a Radio Frequency (RF) transaction using a RF identification device (RFID) transaction device is provided. The method includes a RFID transaction device including a random number generator for generating a random number. The random number may be used by an account issuer to verify the validity of a RFID transaction device or RFID reader communicating on the RF transaction network. The authorizing agent may receive the random number and compare the random number to a device validating code.
