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.
