Abstract
A card on which at least a group of bar-coded information are printed is carried by a motor-driven carrier. The bar-coded information is sensed and converted into a group of parallel digital signals, which is compared with a previously stored data to check coincidence. The same bar-coded information is repeatedly sensed, converted, and compared as above and number of the coincidence times is counted until it has passed a read-in position driven by the card carrier. The card is accepted as readable when the number of coincidence times reaches a preset number. Otherwise, it is rejected by reversing the motor.
