I don't think that many stores track customers and that a lot of the hype from a couple of years ago never ended up in a successful commercialization of the technology.
I think something similar but very different: not many stores mention it, not much news about it, hardly anybody aware of it.
Even companies that provide it talk on their websites about what they'll give you, the data and tooling, not how they'll take it from your customers.
(It's also hard to talk about without sounding tin-foil hat... I don't mean to. I'm mostly resigned to it, the state of advertising etc., I mean I'll block it digitally of course, but I'm not going to go shopping in a balaclava with exaggeratedly not-mine gait or anything, just still dislike that that would be necessary if one did care enough, if you see what I mean.)
Yeah, I got excited when I read "bluetooth proximity marketing" because I was hoping that with a few weekends I could start tricking stores into thinking that everyone I ever bump into just walked into the store with me.
However, google returns a bunch of results talking about the stores sending the customer data. And not the other way around. Also the customer needs a specific app.
It doesn't sound like anyone is tracking anyone via bluetooth. At the very least, if they are, then "bluetooth proximity marketing" is the wrong keyword to search for.
