Geofencing, also called regional monitoring, is the capability to track when a device enters or exits a specified map region. iOS uses this to great effect with Siri to accomplish things like, “Remind me to pick up bread when I leave the office,” or, “Remind me to put the roast in the oven when I get home.” iOS also uses geofencing in Passbook, to help users see the passes that are relevant to them on the home screen (see Chapter 24, “Passbook and PassKit,” for more details).
