Abstract
In an access control system, a registration procedure for a visitor is implemented to control access to an access-restricted zone in a building or a site. At the invitation of a host, the visitor sends a digital image, an invitation identification number and a device-specific identifier of the electronic device of the visitor to the access control system. The image data and the identifier are assigned to a visitor profile previously created for the visitor by means of the identification number of the invitation. The image data are processed by the access control system to generate a reference template, the reference template being stored in the visitor profile.
