inngangsutgangspinner

The term "inngangsutgangspinner" is a Norwegian portmanteau word derived from "inngang" (entrance), "utgang" (exit), and "spinner" (spinner). Literally translated, it means "entrance-exit spinner." In common usage, it refers to a type of rotating barrier or turnstile, often found at entrances to public transportation systems, event venues, or secure areas. These devices are designed to control the flow of people, allowing only one person to pass at a time, typically after a ticket or access card has been validated. The spinning motion of the arms is what gives the device its characteristic name. Inngangsutgangspinner are a common sight in urban environments and are instrumental in managing crowds and ensuring security. They can be simple manual mechanisms or more complex electronic systems that integrate with ticketing and surveillance technology. The primary function is to regulate access and prevent unauthorized entry or exit.
