1. Apparatus for receiving a portable electronic card which includes at least one integrated circuit with a memory and at least one internal contact element coupled with the memory, the apparatus comprising:

  • a. a housing defining an opening for introducing the card;

    b. a slide within the housing, the slide serving as an intermediary for establishing an electrical connection between the card and a circuit outside the card;

    c. a slope within the housing, the slope being disposed so that the slide is taken along the slope by insertion of the card;

    d. at least one spring carried by the slide; and

    e. a flexible insulating foil, carried by the spring, which flexible insulating foil carries at least one external contact element, so that the at least one spring presses the at least one external contact against the at least one internal contact element, after the card is inserted, to establish data transfer between the circuit outside the card and the memory of the card, the same at least one spring being biased between the slide and the flexible insulating foil during said data transfer.
