Barr Group experts also handle geofencing and location-based services. Geofencing uses GPS, Wi-Fi, or cellular signals to define a virtual boundary around a physical area and trigger automated actions (push notifications, check-ins, ad targeting, or device behavior) when a device enters or leaves the zone.
