Apple plans to launch its iBeacon service at 254 of its U.S. stores, reports the Associated Press. iBeacon uses Bluetooth transmitters inside Apple Stores to track the exact location of shoppers.
Customers must download the most recent version of the Apple Store application, and turn their Bluetooth radios on in order for iBeacon to track them. When shoppers move about the Apple Store, iBeacon can sense if they are standing next to a table of iPhones, for example, and will send a message to ask if the customer is interested in an upgrade. The app can also direct shoppers to the check-out counter, or alert them when purchases are ready for pickup. Apple Stores will also be able to send alerts concerning sales or deals to shoppers in the vicinity. iOS device owners need to agree to allow Apple to track them in order for iBeacon to work.
Apple has not updated the Apple Store application since early November, and it is unclear exactly when iBeacon will come online.
