1. Residential area: Regular residential areas are usually closed, so swing gates must be installed to prevent outsiders from entering and exiting at will.
2. Schools: As important places for students to study and live, schools are usually closed, so swing gates must be installed to ensure safety on campus.
3. Enterprises or office buildings: These two types of places are company-based, and generally do not allow random people to enter and exit at will, so swing gates must be installed to block outsiders.
4. Libraries or gymnasiums: These two types of indoor places are membership-based or paid admission, so swing gates are needed to verify entry, and the same is true for clubs and gyms.
5. Parks or scenic spots: These two types of places are paid admission places, so swing gates are needed to verify the ticket information of people before entering to prevent ticket evasion.
6. Railway stations or subway stations: When we take trains or subways, we often see swing gates when entering and exiting these two types of places. We need to swipe our ID cards, tickets, or scan our facial information to pass after verification.
