  • Patent number: 6190942
    Abstract: The invention concerns a process and a connecting arrangement for producing a chip card, wherein a semiconductor chip on a module is fitted in an opening in a card carrier with the attainment of an electrical and mechanical connection. In accordance with the invention, in place of connections which were hitherto necessary involving a force-locking relationship and/or involving the materials being bonded together, recourse is made to inductive and/or capacitive coupling between the module and the IC-card. For that purpose the module and the card correspondingly have coils and/or capacitive coupling surfaces for signal transmission purposes.
