The Triangle Optical Gate Design makes it ample clear which side of the gate can be used to pass through and which cannot. The design employs the use of an intuitive triangle edge on the top and the bottom end of the gates and LEDs help to make them more evident. The gates are the kinds you see at subway stations and can intuitively integrate features like barcode scanners, RFID readers etc.
