The invention relates to a multi-program computer card, the programs being written into identical surface regions 1-2-3-4 and selectable by the direction of insertion of the card into the reader. This card is capable of receiving either a one-off programming, facilitated by a pre-marking, or programming written in large-scale production during its manufacture. By virtue of perforations 21-22 provided in the card, the reader can impose perfect coincidence between the programming and the read sensors with the aid of centring pins 5-6 being inserted into these perforations. <IMAGE>
