The invention relates to an access control system and to a method for operating said system. The system uses a standard access control system ( 24, 8 ), which controls a plurality of access points ( 1 ) by means of respective individual physical closing mechanisms ( 8 ). According to the invention, at least one reader ( 2 ) and a controller ( 3 ), which is connected to the latter in order to control the closing mechanism ( 8 ), is provided at each access point ( 1 ) and the system is equipped with at least one access control server ( 4 ), which carries out the centralised management of access data and is connected to the respective controllers ( 3 ), in addition to at least one mobile telephone server ( 5 ), which is connected to the access control server ( 4 ), said mobile telephone server being at least indirectly capable of transmitting data to mobile radio telephone subscribers ( 7 ) via a mobile radio telephone network and of receiving data from said subscribers. The mobile radio telephone server ( 5 ) can also be an integral component of the access control server ( 4 ). The aim of the invention is to provide an access control system that uses mobile telephones, which can be easily retrofitted and is especially user-friendly and at the same time reliable. To achieve this, at least one access point ( 1 ) is equipped with a short-range transmitter ( 9 ), which transmits identification information that is specific to the access point in such a way that it is only received by a mobile telephone ( 7 ) located in the direct vicinity of the access point ( 1 ) and is used at least indirectly by said telephone to control the access verification process. The use of Bluetooth or WLAN transmitters ( 9 ) is particularly advantageous in this context as modern mobile telephones ( 7 ) are already equipped with interfaces of this type and Bluetooth transmitters ( 9 ) are cost-effective and readily available.
