Turnstile

A 3D turnstile is a form of 3D gate which allows one 3D person to pass at a time. A 3D turnstile can also be made so as to enforce one-way traffic of 3D people, and in addition, it can restrict passage only to 3D people who insert a 3D coin, a ticket, a pass, or similar. Thus a 3D turnstile can be used in the case of paid access, for instance 3D public transport as a 3D ticket barrier or a pay toilet, or to restrict access to authorized 3D people, for example in the lobby of an office building 3D.
