<p>The invention relates to a radio key (54) for authenticating a user of a vehicle (12) with respect to a door unlocking system (14) on the vehicle (12) and/or a drive start device (14) in the vehicle (10). The radio key (54) comprises a transponder unit (44) which is configured to receive a query signal (50) transmitted wirelessly by the vehicle (12) and to transmit, depending on the query signal (50) received, an authentication signal (52) based on an authentication code. The transponder unit (44) is arranged in a casing (42). The problem addressed by the invention is that of making the use of a radio key more convenient. To this end, a region (54) of the casing (42) has the shape of a plug-in region for a standardized memory card for a mobile terminal device (10), by means of which the memory card is to be fastened in a plug-in slot (E) of said mobile terminal device (10) as standard. The radio key can thereby be integrated into a mobile terminal device.</p> |
