As part of the method for operating pay stations of an ID-based access control system for a post-payment scenario comprising a central server (1) and at least one access control device (5), each access control device (5) of the access control system is assigned to a zone and each pay station (4, 4′, 4″) is assigned to a zone. Each zone comprises a unique zone-ID and, at the start of the execution of the method for each zone a presence record created in the central server (1) is forwarded via one or more proxy-servers (2,3) to the pay stations (4, 4′, 4″) of each zone and stored in the pay stations (4, 4′, 4″). Subsequently, at pre-set, definable time intervals or when the Delta changes recorded in the central server (1)—namely the IDs of the customer media no longer present in the zone and the IDs of customer media newly added—a pre-set threshold in a zone for the customer media newly added in this zone and/or for the customer media no longer present in the zone is exceeded, a file containing the Delta changes for updating the presence record stored in the pay stations (4, 4′, 4″) is transmitted via one or more proxy-servers (2, 3) to the pay stations (4, 4′, 4″). |

1. In a method for operating pay stations of an ID-based access control system for a post-payment scenario which comprises a central server and at least one access control device with a plurality of pay stations, wherein each access control device is assigned to a zone, the improvement wherein each pay station of the access control system is assigned to a zone of the access control system, where each zone comprises a unique zone-ID and wherein at the start of the execution of the method for each zone, a presence record created in the central server is forwarded via one or more proxy-servers to the pay stations of each zone and stored in the pay stations, whereupon subsequently, at pre-set or definable time intervals or when the Delta changes recorded in the central server, whereby the IDs of the customer media are no longer present in the zone and the IDs of the customer media that are newly added exceed a pre-set threshold in a zone for the new customer media in this zone and for the customer media that are no longer present in this zone, a file containing the Delta changes for updating the presence record stored in the pay stations is transmitted via one or more of said proxy-servers to the pay stations of each zone. |
