ABSTRACT:
An IC (integrated circuit) card identification system includes a comparator for comparing a first identification number entered by a cardholder with a second identification number, a storage memory for storing at least the second identification number, a timer for measuring a time lapse during a card-identifying operation, and a central controller for controlling the timer to set a first processing time period to be substantially equal to a second processing time period. During the first processing time period, the comparator determines that the first identification number is coincident with the second identification number since the first identification number has been entered. During the second processing time period, the comparator determines that the first identification number is incoincident with the second identification number since the first identification number has been entered.
