21 Claims

21. A computer-readable medium having stored thereon a plurality of instructions configured to cause an authorized sample receiver to perform a method, the plurality of instructions comprising:

instructions to receive a customer payment device transaction request, an encrypted customer payment device authentication code, and a unique customer payment device identification code from an RF customer payment device, wherein the encrypted customer payment device authentication code is associated with a customer payment device authentication code;

instructions to decrypt the encrypted customer payment device authentication code using a unique customer payment device decryption key corresponding to the unique customer payment device identification code, to create a decrypted customer payment device authentication code;

instructions to authenticate the RF customer payment device in response to the decrypted customer payment device authentication code matching the customer payment device authentication code; and

instructions to authorize the customer payment device transaction request in response to transaction keystroke scan sample data matching registered keystroke scan sample data, wherein the registered keystroke scan sample data is associated with the RF customer payment device and the registered keystroke scan sample data is created in response to verification of proffered keystroke scan sample data, and wherein the RF customer payment device is activated in response to the verification of the proffered keystroke scan sample data.
