Turnstiles

A turnstile is a form of gate which allows one person to pass at a time. A turnstile can be configured to enforce one-way human traffic. In addition, a turnstile can restrict passage only to people who insert a coin, ticket, pass, or other method of payment. Modern turnstiles can incorporate biometrics, including retina scanning, fingerprints, and other individual human characteristics which can be scanned. Thus a turnstile can be used in the case of paid access (sometimes called a faregate or ticket barrier when used for this purpose), for example to access public transport, a pay toilet, or to restrict access to authorized people, for example in the lobby of an office building.

Turnstiles provide superior access control by both detecting and deterring unauthorized entries. When entering a facility, often the first point of entry is through a door. A common solution to secure the facility is to add a card or biometric reader and electric locks to the door.
