A subway gate, often referred to as a turnstile or metro gate, is a mechanical or electronic barrier designed to control access to subway stations and other transit systems. These gates are a common sight in urban transportation hubs worldwide and serve several essential functions.
Subway gates are strategically placed at station entrances and exits, ensuring that only authorized passengers can enter and exit the transit system. They are typically equipped with a payment system, such as contactless smart cards or tokens, which passengers must use to gain access. In many modern systems, passengers can also use mobile apps or QR codes for entry.
