Abstract

The invention relates to a method of operating an access control system having a base station, which is located on an object to be protected from unauthorized access, and a data storage medium which can be carried by a user and is arranged to exchange signals with the base station to determine access authorization and to control the base station appropriately, wherein substantially the same carrier frequency is used for signal transmission from the base station to the data storage medium and from the data storage medium to the base station, comprising the steps of: a) initialization of the base station and the data storage medium; b) provision of an information code, which is generated in parallel and identically both in the base station and in the data storage medium; c) configuration of the receiver and/or transmitter both in the base station and in the data storage medium, using at least part of the information code or control information derived from the information code, without the information code, parts thereof or control information derived therefrom being transmitted between the base station and the data storage medium.
