<p>The terminal (1) contains a micro-controller, a contact arrangement (2) for chip cards (3), and an integrated keyboard unit (5). It is connected through an interface (6) with an EDP arrangement (7) to provide a first data path which enables a bidirectional data exchange. The chip card terminal contains a gate circuit (4) controlled by a control arrangement (8) which is connected over a second data path over the contact arrangement with the chip card, and over a third data path with the integrated keyboard unit. The control arrangement is connected over the first data path with the interface. The EDP arrangement generates the data traffic to the chip card over the first data path, and generates in addition the instruction for an entry of identification information from the third data path to the second data path to control the gate circuit.</p> |
