Geofencing is a feature of a software or program that utilizes the “global positioning system (GPS)” or “radio frequency identification (RFID)” component to determine geographic boundaries virtually. The geofencing companies program allows the administrator to determine the trigger point that conveys a signal (SMS or Email) if the device equipped with GPS or RFID crosses the boundary of the “geofence” fence, both in and out of the specified fence line. The geofencing application feature can involve other services such as Google Earth, to determine the virtual fence line, or be determined in the form of coordinates (longitude and latitude).
Location-aware resources allow your application to interact with the physical world and they are ideal for increasing user involvement. Although many mobile applications use it, the topic of this tutorial is a feature that is often overlooked, geofencing. Geofence is a virtual perimeter that is in a real geographical area. Combining the user’s position with the geofence, it is possible to find out whether the user is outside or inside of geofence or even if he exits or enters the area.
Geofence knows if the location is inside or outside of its restricted use area. Imagine a university application that can tell you which colleagues and professors are currently on campus. Or applications for malls that reward regular customers. There are many other interesting possibilities that you can explore.
Geofence is an interface that represents the geographical area that must be monitored. This is created using Geofence Builder. During creation, you specify the area monitored, geofence expiration date, responsiveness, identifier, and type of transition that should be sought. To maintain minimum power consumption, you need to to use geofence with a minimum radius of 100 meters for most situations. If geofences are in the country, you must increase the radius to 500 meters or higher to ensure effective geofences.
