Turnstile gates are mechanical or electromechanical barriers designed to control pedestrian flow by allowing one person to pass at a time through an access point. They serve both as a security checkpoint—restricting entry to authorized individuals—and as an efficient means to count and manage foot traffic in venues ranging from transit stations to corporate offices. There are several common types of turnstile gates—Tripod, Full-Height, Flap (Wing), Speed Gate, and Swing Barrier—each with unique features, components, and ideal applications. Modern turnstiles can integrate with advanced access control systems, including facial recognition, palm vein recognition, QR code scanning, and swipe-card readers, providing versatile security solutions tailored to varied environments.

What Are Turnstile Gates?
Turnstiles (also called gatelines, baffle gates, or automated gates) are access-control devices that enforce one-person-at-a-time passage, often bi-directionally configured for entry and exit. They typically require a credential—such as a ticket, token, swipe card, or biometric scan—to unlock the barrier and permit access . From simple ratchet-mechanism stiles to sophisticated motor-driven arms with electromagnetic locks, turnstiles enhance security by preventing tailgating and providing accurate head-counts in real time Turnstiles.

FAQ
A turnstile gate is an access-control barrier that allows only one person to pass at a time by locking its arms or panels until a valid credential (card, ticket, QR code, or biometric) is presented, then rotating or sliding to admit the user and resetting to block subsequent entries
The primary types are:
Tripod Turnstile (three rotating arms)
Full-Height Turnstile (floor-to-ceiling enclosure)
Flap (Wing) Barrier (retractable glass or acrylic panels)
Speed Gate (ultra-fast, sensor-triggered barriers)
Swing Barrier Gate (pivoting panels with ADA-compliant lanes)
Full-height turnstiles provide maximum deterrence because their solid, ceiling-to-floor design prevents climbing over or crawling under barriers.
Modern turnstiles embed or connect to modules such as infrared cameras for facial recognition and vein-pattern scanners for palm-vein authentication, interfacing with the control board to grant touchless, rapid access.
They use infrared or optical sensors to detect multiple users attempting entry on a single authorization and trigger alarms or immediate relocking to block unauthorized pass-throughs.
Yes—swing barrier gates and some flap barriers can be configured with lanes up to 900 mm wide, equipped with anti-pinch sensors and staff-controlled override to accommodate wheelchairs and strollers.
Routine care includes monthly lubrication of bearings and hinges, quarterly cleaning of sensors and readers, and annual firmware updates and calibration of biometric modules to ensure consistent performance.
Key considerations are expected throughput (persons/min), security level, footprint and mounting constraints, desired credential types (RFID, biometrics, QR), power-supply location, and integration with existing control systems.
