1. A communication device comprising:
- a chip card comprising;
data processing means which make possible the storage of data containing at least identification data of a subscriber of a telecommunication network;
electrical contacts on the surface of the chip card which make possible the exchange of data between the processing means and a mobile apparatus into which the chip card can be removably inserted;
a communication controller for controlling the direct exchange of data via a contactless interface integrated into the mobile apparatus between the chip card and, relative to the mobile apparatus, an outside device without making use of the mobile radio network during the data exchange; and
a power storage for providing power to the communication controller when a battery of the mobile apparatus is exhausted or when the mobile apparatus is switched off.

Abstract
A mobile apparatus includes a removable SIM chip card having data-processing means intended among other things for storing identification data of a subscriber in a GSM mobile radio network. The mobile apparatus has additionally at least one wireless interface integrated in the housing. The interface may be infrared or inductive. By means of this interface, the SIM card can communicate directly, without making use of the mobile radio network, with an outside device in both directions. The chip card contains additionally a communication controller to encrypt data and transmit them via the interface. The contactless interface may preferably be fed independently of the mobile apparatus.
