Geo-fencing is a location-based technology that creates a virtual boundary around a specific geographic area. When a device, such as a smartphone or GPS tracker, enters or exits this boundary, it triggers automated actions like notifications, alerts, or data logging. This technology is widely used in marketing, security, logistics, employee tracking, and more.
Geo-fencing relies on GPS (Global Positioning System), RFID (Radio Frequency Identification), Wi-Fi, or cellular data to detect when a device crosses a predefined boundary. Businesses and organizations can set up geo-fences using software applications, defining areas as small as a building or as large as a city. Once the system detects movement in or out of the zone, it can trigger specific actions.
