A card reader for electronic memory cards of the type which include a integrated circuit and integral electrical contact pads. The card reader includes a slot for introduction of the card. Within the slot are a series of contact elements for supplying power and information signals to the contact pads on the memory card. A card position detector, e.g. a microswitch, detects when the card is in the correct position, i.e. when the contact elements are contacting the electric contact pads of the memory card. When the card is so positioned, electric power and information signals are applied to the contact elements and then to the integrated circuit of the memory card via the electric contact pads.
