A turnstile access control system is a type of security system that regulates entry and exit at a specific point of entry, such as a building, stadium, or subway station.
The system typically consists of a mechanical or electronic barrier, such as a rotating arm or a gate, that allows only one person to pass through at a time.
The turnstile access control system can be designed to accept different types of credentials, such as ID cards, biometric information, or tickets.
The system can also be configured to detect and prevent unauthorized entry or tailgating, where one person follows another through the turnstile without presenting their own credentials.
Turnstile access control systems are commonly used to enhance security and improve traffic flow in public areas where a large number of people need to be processed quickly and efficiently.
