A geo-fence is a virtual boundary that is set up around a specific geographical area. It uses GPS, RFID, Wi-Fi, or cellular data to define the perimeter of the area. When a device, such as a smartphone or a GPS-enabled asset, enters or exits this area, it triggers a predefined response or action, such as sending notifications, alerts, or enabling certain functionalities.
