I love the way you can plot people's movements via bluetooth, but it's also the reason I turn my own bluetooth off. I wonder if there's a need for something that broadcasts like bluetooth does with minimal power, but allows you to change your identifier at will instead of relying on your MAC address. An app on your phone would let you configure how often your token rotated, or to not broadcast at all. The problem that I see with this is that nobody would install the app because it provides no benefit to them. Maybe that's what's missing, such tracking needs to be beneficial for the customer but at the moment it benefits only the retailer.
