A turnstile, also called a baffle gate, is a form of gate which allows one person to pass at a time. It can also be made so as to enforce one way traffic of people, and in addition, it can restrict passage only to people who insert a coin, a ticket, a pass, or similar. Thus a turnstile can be used in the case of paid access (sometimes called a faregate when used for this purpose), for example public transport as a ticket barrier or a Pay toilet http://en.wikipedia.org/wiki/Pay_toilet, or to restrict access to authorized people, for example in the lobby of an office building.
Turnstiles are used at a wide variety of settings, including stadiums, amusement parks, museums, mass transit stations, office lobbies, retail sites, cafeterias, temporary exhibits, ski resorts, casinos and souvenir stands.
From a business/revenue standpoint, turnstiles give an accurate, verifiable count of attendance. From a security standpoint, they lead patrons to enter single-file, so security personnel have a clear view of each patron. This enables security to efficiently isolate potential trouble or to confiscate any prohibited materials.
Persons with disabilities may have difficulties using turnstiles. In these cases, generally a wide aisle gate or a manual gate may be provided. At some locations where luggage is expected, a line of turnstiles may be entirely formed of wide isle gates.
