The processing portion may include (1) a memory portion that stores stored data; (2) a device identification portion that identifies the device based on the device differentiator number and an account number, the account number being derived from the transaction data; (3) a register portion that maintains a count of financial transactions so as to provide a current transaction count value associated with the input device differentiator number for the account number, the register portion maintaining current transaction count values for respective device differentiator numbers, which device differentiator numbers are associated with the account number; and (4) an authentication portion that performs authentication processing based on a comparison process that utilizes the current transaction count value and the input transaction count value, the authentication portion generating an authentication result, the authentication portion outputting the authentication result.
