What Are Turnstiles?
Turnstiles are machines used at railway stations and similar locations to verify the validity of tickets and collect them.
In large urban stations, automatic turnstiles are often installed. These turnstiles read ticket information, confirm their validity, and can interact with contactless IC cards to record boarding sections and deduct fares.
Automatic turnstiles have internal mechanisms such as rollers, punch machines, and magnetic processing units. When a ticket is inserted, the roller transports it to the magnetic processing unit, which reads the magnetic information on the back of the ticket. If the ticket is valid, the turnstile punches a hole in it, returns it, and opens the gate.
