Apple Pay and/or cash defeats this, though.

  Wouldn't Apple keep a record of your transactions? They even send a push notif with the receipt so they are aware of the location and store.

    It defeats the grocery store tracking mentioned in the parent post - Apple Pay uses a different temporary credit card number for each transaction, so the store can't track you with it. I'm not sure what the server side component is - but I don't believe they would have itemized data. So Apple/Amex know that you go to Whole Foods, but don't know what you're buying. Obviously, credit card companies have always had that data anyways.

  "Those shopping cards" probably means coupon cards. It doesn't matter how you pay if you also put in your personal QFC number at every transaction.
