In the Razorfish Emerging Experiences labs, we’ve been prototyping next generation retail experiences that can identify and track consumers with the goal of offering timely and relevant information. Using Bluetooth Low Energy (BLE) indoor location-based tracking, we’re able to see movements and identities of smartphones throughout retail environments. Our systems know how many people are in a space (image below), who they are, when they entered, where they went, where they lingered, and when they left. Based on the location of consumers, we can serve contextually relevant content to their smartphones or to displays in their proximity.
