Estimote Beacons
iBeacons are tiny Bluetooth transmitters that trigger notifications in smartphone apps when the smartphone is near the beacon. Target and other retailers are using beacons to trigger contextual sales and discounts to the mobile devices of shoppers as they enter specific departments in a store. Use these Estimote Beacons to create your own location-aware app.
