1. A system comprising:
- a tangible, non-transitory memory communicating with a processor for securing a transaction,the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the processor, cause the processor to perform operations comprising;
receiving, by the processor, a transaction device random number;
looking up, by the processor using the transaction device random number, a previously stored decryption key; and
decrypting, by the processor using the previously stored decryption key, at least one of a transaction device identifier and a transaction device authentication tag.

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 transactions network. The authorizing agent may receive the random number and compare the random number to a device validating code.

18. An article of manufacture including a non-transitory, tangible computer readable medium having instructions stored thereon that, in response to execution by a computer-based system for securing a transaction, cause the computer-based system to perform operations comprising:
-
receiving, by the computer-based system, a transaction device random number; looking up, by the computer-based system using the transaction device random number, a previously stored decryption key; and decrypting, by the computer-based system using the previously stored decryption key, at least one of a transaction device identifier and a transaction device authentication tag.
