Romania-based CoSoSys Ltd. added geofencing to its mobile device management software last fall. Geofencing technology tracks the location of a mobile device via GPS, Wifi and Bluetooth beacons. The first major use of the technology is for companies tracking visitors. Technology can be combined with other security elements, such as timing, to enforce more granular restrictions. It can also be used to whitelist locations that authorized devices can be used only during working hours. Technology also offers the potential for some convenient, time-saving functionality.”]
