A DEVICE FOR TRANSPARENT INTERACTION BETWEEN AN IC CARD AND A REMOTE TERMINAL

摘要

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 transparantly 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.
