Abstract
A credit card system includes a card having storage columns for recording first identification information, a generating unit for generating a check code from the first identification information and second identification information, a card reader/writer for reading information from and writing information on the card, a keyboard for entering the second identification information and a check code. A comparing unit compares the check code generated by the generating means with a check code entered by the keyboard or a check code recorded on the card, and a unit for indicating or displaying information representing that the check codes compared by the comparing unit do not agree with each other if the compared check codes do not agree with each other.
