Geofencing is a location-based technology that involves creating virtual boundaries or perimeters around a physical location using GPS, Wi-Fi, or cellular data.

When a mobile device enters or exits these predefined geographical boundaries, it triggers an action or notification on the device or a connected system (such as sending a push notification to the user).

Geofencing can be used for many purposes, such as monitoring employee locations and movements. It is often used for attendance capturing of employees on the field.
