Abstract
A building door system has operating and wayfinding devices, wherein each of the operating and wayfinding devices is assigned to a respective single-door system and can be connected to one another for communication with a communications network. Each operating and wayfinding device has a storage device storing an identifier, a control and processing device, a recognition device for detecting a credential of a person, and a display device, which has a user interface facing outdoors. When an invalid credential for the single-door system is detected, the control and processing device generates a request signal containing data of the credential and the individual identifier and feeds this into the communications network. The control and processing device receives a response signal via the communications network, extracts wayfinding information contained in the response signal and assigned to the credential, and activates the display device to display the wayfinding information on the user interface.
