The invention relates to a registration unit for contactless communication between an information carrier (10) and a mobile unit (11). The invention enables safe identification with mobile equipment, which has previously been difficult to perform owing to size, price, unwieldy shape and functionality. This is achieved by the communication between the information carrier and the mobile unit taking place by means of radio waves, via a module (12) which is accommodated in a space for memory expansion in the mobile unit (11).
