ABSTRACT:
A card holder inputs personal identification number (PIN') data as secret data and transaction data (AMT) in an LSI in an identification card through a keyboard. The LSI calculates encrypted data (SAN) in accordance with the input data (PIN' and AMT). The encrypted data (SAN) is shown by the card holder to a cashier at a point-of-sales (POS) terminal. The POS terminal performs authentication of the card and the card holder in accordance with the encrypted data (SAN).
