To mark the release of the new iPhones – and in part to demonstrate a proof-of-concept – Apple retail stores will implement iBeacon customer tracking to reportedly enhance the shopping experience for customers. iBeacon is similar to GPS, but it works indoors and it can be used to trigger certain actions on iPhones that are in proximity to iBeacon sensors. The plan is for iBeacon to work in conjunction with the Apple Store app and offer customers deals and location-based information. It’s an important development for the technology, one that marketers and consumers alike should keep a close eye on; it could determine brick-and-mortar interactive behavior for the forseable future.
