    What is Geofencing and How Does It Work?

    Defining Geofencing

    Geofencing creates a virtual boundary around a specific geographic area. It enables automatic actions when a device crosses this boundary. It uses GPS, Wi-Fi, RFID, and cellular data to define these zones, which can be any shape or size—such as a circle around a store or a polygon covering complex areas. The system tracks targeted devices like smartphones or GPS trackers, triggering preprogrammed responses—such as sending ads, alerts, or security notifications—upon boundary crossing.

    How Geofencing Operates

    The system monitors device location in real-time or periodically, depending on whether it is active or passive. Active geofencing requires user opt-in and offers instant updates; passive geofencing works quietly in the background. For example, a retail store might send a promotional push notification to customers walking within its geofence. Conversely, a fleet management system alerts managers if a vehicle exits a designated zone.
