According to the invention, a mobile device comprises a removable SIM chip card (2) with data processing means (20) for storing identification data relating to a subscriber in a GSM mobile communications network (4) for example. Said mobile device also has at least one wireless interface (14; 15), said interface being integrated in the housing. The interface can be infrared or inductive and enables the SIM card to communicate directly with an external device (3; 3), in both directions, without using the mobile communications network (4). The chip card also contains a communication controller in order to encode data and transmit said data across the interface. The contactless interface can be supplied preferably independently of the mobile device.

Cet appareil mobile (1) comprend une carte à puce amovible (2) faisant partie d'un module d'identification d'abonné avec des moyens de traitement de données (20) destinés, parmi d'autres, à mémoriser les données d'identification d'un abonné à un réseau radiotéléphonique mobile (4) de type GSM. L'appareil mobile comprend en outre au moins une interface sans fil (14; 15) intégrée dans le boîtier. L'interface peut fonctionner aux infrarouges ou par induction. Cette interface permet à la carte du module d'identification d'abonné de communiquer directement et dans les deux directions, sans faire appel au réseau radiotéléphonique mobile (4), avec un dispositif externe (3; 3'). La carte à puce contient en outre une commande des communications qui code les données et les transmet par ladite interface. L'interface sans contact peut de préférence être alimentée indépendamment de l'appareil mobile.
