CA 2219198

The invention provides a device (1) for providing a transparent exchange of commands and data between an IC card (11) and a remote terminal (42) via a communication network (41). The device (1) acoustically couples the IC card (11) with a telephone set (43). In order to speed up the exchange of data and commands, the device (1) preferably utilizes high level commands which represent several low level card commands. However, low level commands may also be transparently passed as a special high level command. The device (1) is inexpensive but allows an efficient use of IC cards for e.g. payment and identification purposes.

L'invention porte sur un dispositif (1) permettant un échange transparent de commandes et de données entre une carte à circuit intégré (11) et un terminal (42) éloigné, via un réseau (41) de télécommunications. Ce dispositif (1) permet de coupler de manière acoustique la carte (11) à un appareil téléphonique (43). Afin d'accélérer l'échange de données et de commandes, on utilise de préférence dans ce dispositif (1) des commandes de haut niveau, lesquelles représentent plusieurs commandes de carte de bas niveau. Cependant, des commandes de bas niveau peuvent être également transférées de manière transparente comme une commande spéciale de haut niveau. Ce dispositif (1) est bon marché mais il permet une utilisation efficace de cartes à circuits intégrés, par exemple dans un but de paiement et d'identification.
