Want to know what makes a flap barrier gate reliable in high-traffic transit hubs? In this video, we demonstrate the AKT313 optical flap turnstile in action — showing its 0.8-second flap retraction, 35–50 persons/minute throughput, and 6-pair infrared tailgating detection. Watch a full walkthrough of RFID, QR code, and face recognition access, bi-directional lane control, fail-safe emergency evacuation, and reader integration options for metro, airport, and BRT deployments.
