Geofence
Geofencing concept
Geofencing is a mobile device technique to create virtual fences on real world locations and track down user's entrances and exits from a defined perimeter. It uses GPS or Radio Frequency Signal data to determinate the geofences location and the transitions between entries and exits.
A common use of geofence is to track down when a user entered or exited a city area and send promotional messages from nearby stores.
Duopen Geofencing library
Here is an example which will help understanding the proposition of the geofencing library by Duopen:
he DuopenGeofence library, developed by Duopen, enables mobile applications (Android and iOS) to capture user entrance and exit transitions within a predefined perimeter. This library prioritizes user privacy and minimizes battery consumption by avoiding continuous location tracking, focusing solely on geofence transitions.
With this data we can know precisely the date and time when the user entered or left a certain location, therefore, this will help our system to automatically categorize the user's transactions at that location. This will also provide crucial information to establish a customer profile for that user.
