iBeacons/blue tooth
Retailers can place small pieces of hardware called iBeacons throughout a store to track shoppers' movements. The devices send out messages to sensors inside your mobile phone and detail its location. (These sensors, which are in nearly every phone, help with games and make a screen switch from normal mode to landscape.)
Marti said when used properly, iBeacons can track where a person is standing, up to six meters, with 90% accuracy.
iBeacons can be placed anywhere in the store, including on products, to alert when they are picked up, added to a cart or put back on the shelf, explained Kohen.
