QR code ticket tripod turnstile is a mechanical gate that is used to control the flow of people entering and exiting at stadium, amusement parks, museums, tourist sites etc.

The turnstile is designed to allow only one person to pass through at a time, preventing unauthorized entry and controlling the number of people who are inside the venue at any given time.

By limiting the number of people who can enter the venue at one time and verifying that each person has a valid ticket or pass, turnstiles help to prevent overcrowding and reduce the risk of unauthorized access.
