Abstract
An access control gate with a mechanical guide forms one or more access lanes for patrons. A contactless access reader which is connected to a software controlled verification system identifies access right of patrons shortly before the person approaches a gate threshold formed by two motor driven flaps which when closed protrude into the access lane from left and right of the lateral lane boundaries. A verification system activates the flaps when an access right has been granted. Two or more photoelectric barriers define a detection zone behind the gate threshold and detect the passage of patrons through the gate threshold and the exit of the detection zone. The flaps are closed with highest possible speed after the patron has left the detection zone regularly, and are moved with low speed if an irregular passage is detected.
