>> You're already being tracked by the grocery stores > > With cash and no store "loyalty" app - no. Assuming no facial recognition, phone tracking or license plate reading, all that means is they aren't tracking you between visits. Certainly the items purchased together are tracked. And they get lumped together into the "cash, no card" group. And if you buy any age restricted products where they can see your ID, your birthdate is entered into the system, which is probably unique enough among cardless cash users in any grocery store.
