What is the subway turnstile?
In public transportation facilities like subway and other subways, a turnstile is a feature that is employed in controlling the passage of individuals securely and with a smooth flow while admitting only a single person at a time in order to forestall unauthorized passage and promote neatness. These devices are often equipped with technologies such as card readers or QR code readers in order to provide more convenient and easier ticketing processes for commuters. Devices applied in managing the inflow and outflow of individuals at subway entrances and exits through processes such as card payments. Using QR codes and facial recognition for payments plays a crucial role in efficiently handling ticketing charges.
Working principle
The way a subway turnstile operates includes a mix of parts and sophisticated electronic systems at play in sync with each other. When someone gets closer to the turnstile with a ticket or payment option (like a metro card or QR code on their phone), the system checks the details using scanners or readers built into it. After confirming the validation of the credentials, the turnstile briefly unlocks to let a single person pass through.

One good example of how KARSUN showcases this principle is through its cutting-edge product designs.
