1. A process for recognizing card terminals using chip cards comprising:

  • emitting different electromagnetic waves from a plurality of card terminals, wherein each of the card terminals differs from another card terminal in terms of one or more physical properties of a member selected from a group consisting of frequency, phase, energy density, and amplitude;

    providing chip cards for simultaneously receiving and recognizing the different electromagnetic waves from the different card terminals based on these different physical properties;

    exchanging energy and data between the card terminals and the chip cards by means of the electromagnetic waves, wherein each chip card comprises an electronic circuit and contactless connection means, and wherein the electronic circuit and the contactless connection means are electrically connected to each other; and

    activating different functions of the chip cards depending on the card terminals recognized by the chip cards.
