      Wait, don’t Bluetooth devices randomize their macs like wifi to hide their identities from unpaired devices?

      These beacons are small, inobtrusive electronic devices that are hidden throughout the grocery store; an app on your phone that communicates with them informed the company not only that you had entered the building, but that you had lingered for two minutes in front of the low-fat Chobanis.

      Well that solves the problem. Don’t let sketchy apps access your Bluetooth/location

        They don’t have to be connected to see your device. Just like how Find My Device works by searching for the Bluetooth signal. You’d need to have Bluetooth completely off, so no smart watches or headphones for you in the grocery store I guess.
