Geo Fencing works by combining geographic coordinates with a boundary radius to create a virtual boundary around each approved location.
1. An admin defines allowed locations by entering the Latitude, Longitude, and Radius (in meters) for each.
2. When an employee tries to punch through the mobile app, the app checks their current location against the defined boundaries.
3. If the location is inside an allowed boundary, the punch is accepted.
4. If the location is outside all allowed boundaries, the punch is blocked and the employee sees an error.
