Application of iBeacon:
1. Distributing messages at a specific Point of Interest.For example a store, a bus stop, a room or a more specific location like a piece of furniture or a vending machine. This is similar to previously usedgeopushtechnology based onGPS, but with a much reduced impact on battery life and much extended precision.
2. Indoor positioning systemwhich helps smartphones determine their approximate location or context. With the help of an iBeacon, a smartphone's software can approximately find its relative location to an iBeacon in a store.Brick and mortarretail stores use the beacons formobile commerce, offering customers special deals throughmobile marketing,and can enablemobile paymentsthroughpoint of salesystems.
