context_page_description: A turnstile 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 human traffic, 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, for example to access public transport, a pay toilet, or to restrict access to authorized people, for example in the lobby of an office building.
context_section_description: The full-height turnstile is a larger version of the turnstile, commonly 7-foot (2.1 m) high, similar in operation to a revolving door, which eliminates the possibility (inherent in the waist-high style) of someone jumping over the turnstile. However, this type of turnstile functions differently than a revolving door, in that it often does not allow someone to come in as someone else goes out. It is also pejoratively known as an "iron maiden", after the torture device of the same name, or "high-wheel". It is sometimes called a "Rotogate", especially in Chicago, where it is used at unstaffed exits of Chicago 'L' stations, and is also used increasingly in New York City Subway stations since the turn of the 21st century. In Europe, however, "Rotogate" refers to a different kind of gate that is not a turnstile. 
  There are two types of full height turnstiles, High Entrance/Exit Turnstile (HEET) and Exit-Only. The difference between them is that HEET turnstiles can rotate in both directions thus allowing two-way traffic, while exit-only turnstiles can only rotate in one direction thus allowing one-way traffic. Exit-only turnstiles are commonly used in mass transit stations to allow passengers to exit the system without interfering with those entering. Exit-only models are also used at enclosed areas such as theme parks, zoos, or amusement parks, to allow visitors to leave, while denying admission to those who have not paid.  Additionally there are single, and double or tandem turnstiles that contain two rotors side by side in the same frame.  This allows more throughput in a limited space, as tandems frequently are more narrow than two single turnstiles placed side by side.
