Geofencing is a location-based service that uses GPS, Wi-Fi, or other technologies to create a virtual boundary around a physical location. When a device or user enters or leaves the defined boundary, a pre-programmed action is triggered.
Geofencing is often used in marketing, to send targeted ads or notifications to users who are near a particular location. It can also be used in security and safety applications, to alert authorities or emergency services when a person enters or leaves a protected area. In addition, geofencing can be used in the workplace to track employee attendance and productivity, or to control access to secure areas.
There are a variety of ways to implement geofencing, including using mobile apps or software, or by integrating geofencing capabilities into a device or system. Some geofencing systems can be set up to trigger an alert or action when a device or user enters or exits a defined boundary, while others can be configured to trigger an action only when the device or user has been within the boundary for a certain period of time.
