<p>The invention relates to a method for operating an access control system comprising at least one door fitting (1) to a secured area of a building and at least one identification code (T2) on a mobile data carrier (2). The identification code (T2) is read by a read device (10) of a door fitting (1). If the read-in identification code (T2) is valid, access is granted to the area secured by the door fitting (1). An authorization code (T15) is transmitted from a processor (3) via at least one communication connection (31, 31') to a central processor (4). A verification step is carried out to determine whether the transmitted authorization code (T15) corresponds to a valid authorization code for an area profile (T1). Upon successful verification of the transmitted authorization code (T15), write and read rights for the area profile (T1) are released to the processor (3) transmitting the authorization code (T15). The released area profile (T1) is changed by the processor (3) via a communication connection (31, 31').</p> |
