PURPOSE:To input a password number to display stored data on an IC card by providing the IC card with a control part, a discriminating part, a storage part, an input/output part, a power source part, a key input part, a display part, and a sound producing part. CONSTITUTION:A control part 2 provided with a microcomputer controls each part. When a password number is inputted with ten keys of a key input part 7, the password number stored in a storage part 4 is compared with the inputted password number to perform discrimination by a discriminating part 3. When the inputted password number is correct, for example, the balance is displayed on the liquid crystal panel of a display part 8. Next display is requested by an instructing key. For example, the total amount of money is displayed. At this time, a preliminarily set amount of money and the balance or the like are compared with each other by the discriminating part 3, and a buzzer of a sound producing part 9 is sounded based on the comparison result. The amount of money for cautions to the balance or the total amount of money can be preliminarily set by ten keys and the instruction key of the key input part 7. |
