But Apple does not store any personal information through iBeacon, a spokesman said. The technology is designed to only work one way, from the hardware to the phone. The hardware component emits a signal and the phone recognizes it, but nothing is sent back to the hardware, the spokesman said.
Beyond improving the bottom line for its own stores, Apple hopes its iBeacon technology could usher in all sorts of applications. The technology could provide third-party apps "a whole new level of micro-location awareness, such as trail markers in a park, exhibits in a museum, or product displays in stores," Apple said in a statement.
