Mobile device, chip card and method of communication

   
   

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.
