Abstract
A mobile device which is assigned to a person transmits an identification to a central device where localization of the mobile device is initiated. After the mobile device has been located in an area of an access system, the identification is checked for authorization for access via the access system. Access via the access system is either allowed or denied based on the result of the check. Access by an authorized person to secure areas or devices with the aid of a wireless device which is usually carried along—for example a mobile radio terminal or a DECT terminal—thus becomes considerably easier and more convenient.
