|iBeacon on iPhone|
Apple has switched on its controversial iBeacon snooping system across 254 US stores.
The fruity firm’s iSpy network allows Apple to watch fanbois as they walk around an Apple store and then send them various messages depending on where they are in the shop.
This might come in handy when visiting an Apple store, for instance, which is offering the latest iStuff. Glance in its direction or wander past and your iPhone will suddenly spring to life, filled with messages about products you haven’t bought yet.
Apple’s iBeacon transmitters use Bluetooth to work out customers’ location, because GPS doesn’t work as well indoors. This functionality was quietly snuck into iOS 7.
