> Realistically, what is the worst possible consequence of a supermarket being able to track you? At worst, I suppose you be could be charged more for purchasing a certain item at that particular chain. The way it works in Norway at the moment is that you can get a membership at any of the grocery chains, download an app and what not. Then you register your debit card in that app, and it monitors what you buy, and you get discounted prices on stuff you buy the most of and/or benefits in general. Personally I have no problem with this, because it's an opt-in thing.
