ABSTRACT:
A card reader control system includes a measuring device which measures a time interval of a clock signal which is developed from a card reader when a card is manually driven to travel in the card reader. The card reader control system stores the maximum time interval and the minimum time interval of the clock signal measured by the measuring device. When either one or both of the maximum time interval and the minimum time interval is not included in a preferred range, an alarm buzzer is enabled to indicate that the card speed is not suited for the reading operation.
