The invention concerns a conventional smart card comprising an ISO 7816 eight-contact wheel and at least a standard two-way path, whereby data exchanges at a speed of about 500 Kbits/s are possible. In order to enable said card to be used in an environment requiring data processing of several Mbits, the invention provides for the addition on said card of a high speed series channel connected to the connections not used by the standard two-way path and forming a second bus (HSD) whereon are connected several encryption/decryption modules and a multiplexing module (MUX). Said modules are likewise connected to the card conventional bus.
