Lots of retail does this with Bluetooth™ beacons (whether just at entry/exits, or at high-trafficked areas).

Which is another reason I simply just stopped carrying a cell phone a few years ago. Absolute freedom.

I paid my vehicle off early just so I could disable the infotainment's cell-link. My city has OCR cameras on every 4-lane highway (so I'm still tracked) but it sure is wild how important locations are these days.
