Examples of potential iBeacon services include describing products to shoppers on shelves, or alerting them to deals via push notification, guiding a hiker through a mountain trail, even if they have little or no vision, or helping a visitor find parking and get to the right office for a scheduled meeting. iBeacons are currently deployed in U.S. retail stores, as well as sports facilities and grocery stores.
