    摘要: A system and method for securing a Radio Frequency (RF) transaction using a RF identification device (RFID) transaction device is provided. The RFID transaction device includes a transactions counter for tallying the number of transactions attempted or completed with the RFID transactions device. The counter may be incremented by any predetermined amount, which may be predefined for a particular transaction device counter. The counter value is provided to an account issuer for use in determining if the counter value has exceeded a predetermined value correlative to the maximum number of transactions which may be completed using a transaction device.
