geofencing
n.— «Back on terra firma, “geofencing” will be this year’s buzz word. Wireless location technology will mean the movements of mobile-phone users can be tracked by security forces, who will be able to create “virtual fences” around sensitive locations such as airports. When a suspect’s mobile device gets close, an alarm will be set off. Back on terra firma, “geofencing” will be this year’s buzz word.
