    • The invention pertains to a terminal for chip cards which contain a micro controller. The chip card terminal contains a contact device for chip cards and an integrated keyboard unit and is connected with the interface of a computer system through a first data path, which allows a bi-directional exchange of data. Sufficient security is provided through the integrated keyboard by the fact that the chip card terminal contains a gate circuit, which is controlled by a control system. The gate is connected with the chip card through a contact device by means of a second data path, is connected with the integrated keyboard unit by means of a third data path, and is connected with the interface of a computer system by means of the first data path. The computer system generates the data traffic to the chip card through the first data path and additionally gives the command through the first data path for inserting identification information from the third data path into the resulting second data path, which effects the control of the gate circuit.
    • 本发明涉及一种包含微控制器的芯片卡终端。 芯片卡终端包含用于芯片卡和集成键盘单元的接触装置,并且通过第一数据路径与计算机系统的接口连接,这允许数据的双向交换。 由于芯片卡终端包含由控制系统控制的门电路的事实,通过集成键盘提供了足够的安全性。 门通过第二数据路径通过接触装置与芯片卡连接,通过第三数据路径与集成键盘单元连接,并且通过第一数据路径与计算机系统的接口连接 数据路径。 计算机系统通过第一数据路径产生到芯片卡的数据流量,另外通过第一数据路径给出命令,用于将识别信息从第三数据路径插入到所得到的第二数据路径中,从而实现门电路的控制 。
