Lock fare gates, also called a baffle gate or a swing gate, are types of gates that allow one person through at a time to enforce one-way traffic of people. Some gates require paid access in order to pass through. They may have integrated [[ticket machine]]s to give one their ticket, or use optical interfaces where one can check in with a chipped card.

Types of fare gates include [[turnstile]] (tagged on Danbooru only when depicted as rotating "tripod":https://en.wikipedia.org/wiki/File:Train_ticket_bariiers_in_Cairo_metro.JPG turnstiles), drop arm, full panel, flap barrier, bi-parting, swinging, retracting/sliding, etc.
