A method of controlling access to an area accessible by persons, particularly to a space closed by a door, includes providing a first mobile communications unit on which at least one access code is filed, at least one second mobile communications unit and a receiver unit for receiving the access code. The access code is transmitted by the first communications unit to the second communications unit. The access code is transmitted to the receiver unit by this second communications unit. After a successful checking of the access code by the receiver unit the door access is freed.
