I’ve just always assumed that big stores were collecting and selling every iota of data they could. I recall reading about retailers using license plate scanning in their parking lots in the early aughts.

Yes it's not a surprise, but I think what is surprising is the billion dollar profit this one store is claiming the data are worth.

Anywhere that collects your phone number in exchange for coupons at the checkout (cough cough Old Navy) or your email to send you a digital receipt (looking at you Home Depot) is probably sharing or selling your data.

  OTOH, ubiquitus digital receipts would revolutionize automated plain text accounting for individuals.

  I hope Home Depot made a pretty penny off of selling my email address, which is homedepot@mydomain and not associated with any other accounts.

    Nobody has perfect opsec, and if you screw something up ONE TIME, like leave your phone's bluetooth on ONE TIME, now that super simple email address is added to the profile that these groups have on you.

  Not probably. They're certainly selling your data.

    Unless you are in the EU, where it's illegal thanks to GDPR.

      True. I'm being US-centric. Even though I consider the GDPR to be a bit inadequate, it's orders of magnitude better than what we have in the US, and I'm jealous.

I recall reading about retailers using license plate scanning in their parking lots in the early aughts. They also pick up the unique IDs from the wireless air pressure monitor chips in your tires. Even if you don't have an internet-connected car, they're still tracking you from parking lot to parking lot. That information can then be combined with time/date information and your credit/debit card purchase to identify who you are, where you shop, and what you buy.

  > I recall reading about retailers using license plate scanning in their parking lots in the early aughts. Yep, that technology is called ANPR - automatic number plate recognition. Outputs a license plate, state, date/time, and gps coord of scanner. > They also pick up the unique IDs from the wireless air pressure monitor chips in your tires. That's called TPMS, tire pressure monitoring system. There is 1 device per tire, which emits temp, pressure, serial#, and other data.
