No tinfoil hat needed. Retail stores are equipped with bluetooth beacons that tracks and monitors customer behavior. This in turn can be sold for targeted advertising. Another scary thought is that the tracking is so precise, it measures the distance your phone is from a product, including height. How high is the phone from the ground? The data points can be extrapolated to influence product placement: what products and prices influenced a customer to bend down and look at/interact with the product? How long were they in close proximity with the product? Based on the phone’s orientation, were they bent down to look at or passing by the product (indicating that they stopped for a separate reason and not necessarily for the product)? Did they buy it? Were they looking for coupons in my “retail store app” while next to the product, or somewhere else in the store? Where do customers often stop or gather in order to browse through coupons? Could we place Y products there? Where should we put the product in stores to maximize sales? What ads can we send to them as they arrive at the store? Based on aggregated data with the rich profile we built for this customer, are they likely to sign up for our rewards credit card? What is this customer’s income level? Have they purchased X product recently? What part of town do they live in? What products are popular there? Et cetera ad nauseum.

Tracking is so predatory. Makes me look at my smart phone with disgust as the years go by, and I periodically grapple with the decision if a smart phone is even right for me or if it’s time to stick to a computer and a truly dumb phone going forward.
