Authenticating an RF transaction using a transaction counter
First Claim
1. A method, comprising:
- receiving an authentication request from a radio frequency (RF) transaction device, wherein the authentication request comprises a total transactions counted value, and wherein the total transactions counted value represents a number of transactions associated with the RF transaction device;
denying the authentication request in response to the total transactions counted value exceeding a maximum transactions counted value; and
disabling the RF transaction device in response to the total transactions counted value exceeding the maximum transactions counted value.

Abstract
A system and method for securing a Radio Frequency (RF) transaction using a RF identification device (RFID) transaction device is provided. RFID transaction device includes a transactions counter for tallying the number of transactions attempted or completed with the RFID transactions device. Counter value is used to create a RFID device authentication tag for use in validating the RFID device. A RFID reader, interacting with the RFID device, provides a random number to the RFID device which may be used in the RFID device authentication tag creation and validation. RFID reader may also use counter value and random number to create a RFID reader authentication key useful for validating RFID reader. RFID transaction device may include an encryption key for creating RFID transaction device authentication tag. Likewise, RFID reader may include a RFID reader encryption key for creating RFID reader authentication tag.
