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.
