<p>This invention concerns a conventional smart card comprising a rosette of eight contacts of the ISO 7816 type and at least one standard bi-directional channel, through which the exchange of data at a speed of about 500 Kbits/sec is possible. To allow the use of such a card in an environment that needs a processing of information of several Mb we propose to add on this card a high-speed series channel linked to non used connections by the standard bi-directional channel and to format a second bus (HSD) on which are linked several coding/decoding modules and multiplexing module (MUX). These modules are also linked to the conventional bus of the card.</p> |
