Virgin Atlantic has already installed beacons in London's Heathrow Airport so a smartphone automatically displays a boarding pass when the passenger comes to the gate or security. LabWerk has also produced an app to alert drivers of empty spots in parking garages based on the beacons.
Mobile devices receive the low-power Bluetooth signal within 500ft of a beacon. The transmitter price is now between $5 and $20, but is expected to fall to less than $2 next year.
Apple has also addressed iBeacon privacy concerns, saying the beacons don't track users, since they only send out a signal, and don't receive information.
