Geofencing is a technology that creates a virtual boundary around a specific geographic area and triggers an action when a device or person enters, leaves, or moves within that area. The boundary is defined using location information, often from GPS, Wi-Fi, cellular networks, or other positioning methods. This allows applications to respond automatically to changes in a user’s physical location.
Geofencing is commonly used in mobile applications, fleet management, security systems, retail services, and smart devices. For example, a delivery system can send an alert when a vehicle enters a designated service area, or a store app can provide a notification when a customer approaches a location. By connecting physical locations with digital actions, geofencing enables location-based automation and monitoring.
