Turnstiles

Turnstiles are physical barriers used to control access to a location, allowing only authorized individuals to pass through. Typically found at transit stations, stadiums, or secure facilities, they consist of a vertical frame with rotating arms that open briefly when a valid ticket, card, or credential is presented. This mechanism helps manage crowd flow, prevent unauthorized entry, and ensure fair access. Turnstiles can be mechanical or electronic, integrating with access control systems for seamless security. Their design balances efficiency with security, providing a clear and effective way to monitor and regulate entry points.
