turnstilesTurnstiles are a basic form of access management and control. A turnstile is a type of gate that permits one person to pass through at a time. The purpose may be to direct the flow of people traffic in a certain way, or to restrict access to those who meet certain criteria, such as credentialed pass holders.

Turnstiles are widely used as a first line of security and screening in commercial and government settings including office building lobbies and mass transit stations.
