Beacons are small devices that send out signals over a short distance, generally a few metres in diameter. Devices within this range are able to pick up the signal transmitted by the beacon and this allows you to target users at close proximity with specific messages or actions.
Here we are not only limited to a single beacon. With a network of beacons set up within a single city, metro system, shopping centre or a single store, it’s possible to send highly targeted messages to every person in the area as they move from one location to another.
