ABSTRACT To indicate the number of uses of a card of the type which is magnetically encoded for plural uses, a hole if punched in the card, the distance of the hole from one end of the card progressively increasing with each use. Since the card is continually moving as it is being punched. the punch element is pivoted to an actuating lever and pivots against the force of a spring as the card moves. The spring returns the punch to initial position when the card has passed the punch station. A solenoid pivots the actuating lever. Provision is made for adjustment of the distance of penetration of the punch. A resilient roller engaging the face of the card opposite the punch backs up the punch.
