  • Access control system for controlling access of a user to one or more operating functions of a technical installation
    Patent number: 11468156
    Abstract: An access control system controls access of a user to one or more operating functions of a technical installation. The access control system includes a receiving device configured to read access authorization data from a mobile data medium and an access control device configured to receive and validate the access authorization data from the receiving device. The receiving device continuously adds a dynamic portion to the access authorization data to create dynamic access authorization data and sends the dynamic access authorization data to the access control device. The access control device, in response to the dynamic access authorization data corresponding to a defined expectation, generates a release signal for those operating functions for which the access authorization data is valid.
