A dispenser for cards which are withdrawn by customers at the entrance of a parking lot has a housing for a supply of coherent cards which are transported seriatim by advancing rolls toward an outlet opening for withdrawal by customers. On its way toward the outlet opening, each card is provided with legible information by a matrix printer which can apply such information in response to a signal from a computer while the card is in motion. The thus imprinted card then advances between the matrix and the perforating tool of a punching apparatus which applies one or more holes while the card is in motion. The matrix and the tool are mounted on a plate which is secured to a fixed bracket by a first parallel motion mechanism so that it can move in and counter to the direction of movement of the card between the tool and the martrix. The plate is pivotable about a fixed axis by an oscillating crank gear so that the tool moves along an arcuate path to which the adjacent card is tangential. During each movement in the direction of transport of cards, the tool and the matrix move, for a certain interval of time, at the exact speed of the card. At such time, a cam moves the tool toward the matrix so that the tool perforates the card portion whicn is located between the matrix and the tool. The motor which causes the cam to move the tool toward the matrix receives commands from the computer.
