Q: What are beacons, and how can they boost my sales?

Beacons are small, wireless broadcasting devices that transmit a data signal that can be received by a smartphone—in this case, the one belonging to your customer. Once the beacon and smartphone connect, a retailer or service provider can instantly deliver a welcome message or discount.

There will be 4.5 million beacons in use in the U.S. by the end of 2018, according to a report from BI Intelligence, with 3.5 million of those used by brick-and-mortar retailers.
