Apple's Location-Tracking iBeacon is Poised for Use in Retail Sales

The bigger news was quietly rolled out a little more than a month ago, when Apple unleashed iOS 7 onto the world. Embedded in the mobile operating system's flashier interface and multitasking features is a new technology called iBeacon that can pinpoint your location to within a few feet.
