A system for controlling a user's access to an access-protected unit (4). The system comprises a user unit (1) which is arranged to register at least one pair of coordinates, and checking means (2) which is arranged to check, on the basis of the coordinates, if the user is authorised to access the access-protected unit (4). If the user is authorised, the checking means is arranged to provide an enabling signal to the access-protected unit (4). |
