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 detect the passage of patrons through the gate threshold, wherein the detecting beams are spaced apart by between 1 and 10 inches and directed to the lane zone behind the gate threshold. The flaps are closed after the patron has passed through.
