IC CARD SETTLEMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To dynamically optimize the relation between the cost required for identity certification and the certainty of identity certification in accordance with a value which is to be protected by identity certification. SOLUTION: The input of a shopping amount and a password is received (steps 103 and 105). When the shopping amount is lower than a setting value (Step 107), settlement is executed (steps 111 and 112) if the inputted password matches with a password stored in an IC card. When the shopping amount is higher than the setting value (step 107), the fingerprint of a user is read (step 109) and settlement is executed (steps 111 and 112) only when the fingerprint which is read matches with a fingerprint stored in the IC card (S110).
