Retailers are falling in love with beacons, small Bluetooth devices that interact with apps to send messages to smartphones. They’re deploying them by the thousands, with Macy’s alone placing over 4,000 beacons in the US retail stores. Matthew Davis, VP of Product Marketing at mobile startup Reveal, demystifies this rapidly growing marketing channel. Attendees will hear a brief overview on how the technology works, who is deploying them and where, and how many (over 70,000 installed already in the US alone). The presentation then turns to concrete examples of how major retailers use beacons to increase customer engagement in real-time, and how other companies use beacon data to build targeted audience segments over extended periods of time.
