GPS will tell you how to get to the nearest Apple store. With iBeacon, Apple hopes to guide you around once you’re inside, whether it’s to pick up an order, upgrade to a new iPhone or shop for a pair of headphones.
The implications of iBeacon go beyond Apple stores. One day, commuters might get information on subway delays as they stand on the platform, while museum visitors might get details on the painting they are standing in front of. Other retailers will be also able to offer deals or track which aisles shoppers linger in the longest.
