A system for managing gym memberships. When a user joins a gym, they receive a card that the employee links to their data with a barcode and enters into the system. Each time the user enters the gym, they log in and each time they leave, they log out. This allows the gym employees to see which user is exercising at a given time, what type of membership they have paid, whether it is still valid, and how many people are currently inside the gym. The employee has the ability to edit each user’s data, extend their membership, and delete them from the system if they are no longer a gym user.
