“Beacon” technologies could soon capture data where it is difficult to track consumer interest without old-fashioned interpersonal interaction: brick-and-mortar stores. A partnership between Norwegian media platform Unacast and California-based proximity solutions specialist Total Communicator Solutions plans to capture and gauge consumer interest in specific items in-store using beacons, then use that data to target the same shoppers with online and mobile ads. The partnership represents the first effort to automate and quantify in-person shopping.
