How does a gym turnstile work?

In order to enter a gym, customers must pass through a gym turnstile. This is a type of gate which allows people to enter one at a time. Once someone has gone through the turnstile, they cannot go back through it. This is to prevent people from sneaking in without paying.

There are two types of turnstiles: mechanical and electronic. Mechanical turnstiles have a handle which must be pushed in order to rotate the stile. Electronic turnstiles do not have a handle. Instead, they have a card reader. To go through the turnstile, customers must swipe their membership card or key fob.

Some gyms also have fingerprint scanners. This is a type of biometric security which can be used instead of a card. To use this type of turnstile, customers must place their finger on the scanner. The scanner will then read their fingerprint and grant them access to the gym.

Turnstiles are a simple way to ensure that only paying customers can enter a gym. They are easy to use and can be installed quickly.
