CA 2208252

In order to limit the functions of microprocessors in chip card readers that are also designed to respond to real-time external demands, a coupling circuit is provided for coupling the reader to the chip card. The coupling circuit performs all the timing operations.

Pour limiter les fonctions des microprocesseurs présents dans des lecteurs de cartes à puce qui sont par ailleurs destinés à réagir à des sollicitations externes en temps réels, on a réalisé un circuit coupleur pour coupler le lecteur à la carte à puce. Le circuit coupleur effectue toutes les opérations de synchronisation.
