turnstile
One-at-a-time gate
A turnstile is a mechanical gate with rotating horizontal arms or a revolving door that allows only one person to pass through at a time, typically after inserting a coin, ticket, or transit card.
Turnstiles control access to subways, stadiums, amusement parks, and other venues where entry must be monitored or paid for.
