A subway turnstile is used in subway systems and other mass-transit systems to check patrons‘ tickets. Different types of turnstiles are used in different subways depending on variables like throughput, risk, and aesthetics, but waist high tripod turnstiles are the most common type used.
Turnstiles are used at the entrances of subways to check patrons’ tickets. They only allow access to the subway platforms if a patron presents a valid ticket. Because of this, it is not necessary for companies to hire employees to check tickets on the platforms or inside trains. This automation saves money by reducing labor hours and reducing backup.
