An automatic turnstile barrier is a mechanical gate typically used in areas where crowd control or access control is required. These barriers are commonly found in transportation hubs like train stations, airports, and subway systems, as well as in stadiums, office buildings, and other public venues. Automatic turnstile barriers come in various designs, but they generally consist of a rotating horizontal arm or arms that allow one person to pass through at a time. They are often equipped with sensors or access control systems such as RFID readers, barcode scanners, or biometric devices to authenticate users before allowing them to pass through. https://www.novusapl.com/Semi-Automatic-Turnstile-Gate-NS-TS1-V22D0.php
