1. A system for securing a radio frequency (RF) transaction, the system comprising:
- a radio frequency identification (RFID) transaction device operable to send an RF transmission, the transaction device including;
a database for storing a transaction device identifier and a transaction device authentication tag, wherein the transaction device identifier is different from the transaction device authentication tag,a transaction device random number generator for generating a transaction device random number, the transaction device random number generator being located at the transaction device, anda transmitter operable to transmit the transaction device identifier, the transaction device authentication tag, and the transaction device random number;
wherein the transaction device is operable for transmitting, to a RFID reader, both the transaction device identifier and the transaction device authentication tag for validation, wherein the validation is based at least in part on both the transaction device identifier and the transaction device authentication tag; and
wherein the transaction device random number is used to lookup a previously stored decryption key for decrypting at least one of the transaction device identifier and the transaction device authentication tag, the transaction device random number having been received from the RFID transaction device.

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.

15. A method for securing a transaction comprising:
-
generating a transaction device random number at a radio frequency identification (RFID) transaction device, wherein the transaction device includes a random number generator, wherein the transaction device is associated with a transaction device identifier and a transaction device authentication tag, the transaction device identifier being different from the transaction device authentication tag; transmitting the transaction device identifier, the transaction device authentication tag, and the transaction device random number to a RFID reader; and validating the transaction device based at least in part on both the transaction device identifier and the transaction device authentication tag, both having been received from the transaction device, wherein the transaction device random number is used to lookup a previously stored decryption key for decrypting at least one of the transaction device identifier and the transaction device authentication tag, the transaction device random number having been received from the transaction device. - View Dependent Claims (16)

17. A method for securing a transaction comprising:
-
generating a transaction device random number at a transaction device, wherein the transaction device includes a random number generator located at the transaction device, wherein the transaction device is associated with a transaction device identifier and a transaction device authentication tag, the transaction device identifier being different from the transaction device authentication tag; transmitting, from the transaction device, the transaction device identifier, the transaction device authentication tag, and the transaction device random number to a transaction device reader, wherein the transaction device reader is associated with a reader authentication tag; transmitting, from the transaction device reader, the transaction device identifier, the transaction device authentication tag, the transaction device random number, and the transaction device authentication tag to an account issuer associated with the transaction device; validating, at the account issuer, the transaction device based at least in part on both the transaction device identifier and the transaction device authentication tag, both having been received from the transaction device, wherein the transaction device random number is used to decrypt at least one of the transaction device identifier and the transaction device authentication tag, wherein the transaction device random number is used to lookup a previously stored decryption key for decrypting at least one of the transaction device identifier and the transaction device authentication tag, the transaction device random number having been received from the transaction device; and validating, at the account issuer, the transaction device reader based at least in part on the transaction device reader authentication tag, wherein the transaction device random number is used to decrypt the transaction device reader authentication tag.
