How geofencing works. geofencing is used in advanced location based services to determine when a device being tracked is within or has exited a geographic boundary. to perform this function, the geofencing app accesses the real time location data sent by the tracked device. in most cases, the information is in the form of latitude and longitude. Geo fencing (geofencing) is a feature in a software program that uses the global positioning system ( gps ) or radio frequency identification ( rfid ) to define geographical boundaries.
A geofence is a virtual perimeter for a real world geographic area. [1] a geofence can be dynamically generated (as in a radius around a point location) or match a predefined set of virtual perimeters (such as buildings or commercial facilities). the use of a geofence is called geofencing, and one example of use involves a location aware device. As a customer approaches the store, the geofencing system monitors their smartphone's location in relation to the geofenced geographical location. crossing into this area triggers the system to recognize the customer's entry based on the continuous location data provided by their smartphone. 4. triggering an action. Geofencing is a location based service where software or apps use global positioning systems (gps), rfid, wi fi, or cellular data. it triggers an alert when a location aware device enters or exits a virtual boundary. for example, if a mobile device or rfid tag enters or exits a geofenced area, it can prompt: push notifications. sms messages. Geofencing: what is it? geofencing is a location based service in which an app or other software uses gps, rfid, wi fi or cellular data to trigger a pre programmed action when a mobile device or rfid tag enters or exits a virtual boundary set up around a geographical location, known as a geofence. what does it mean in practice?.
