Can’t they just track everything you buy using your payment card?

    I mean, why bother with the loyalty card? Can’t they just track the payment (debit, credit) card?

      You could have multiple cards; idk how it works for the US but maybe they cant see the card owner? So if a loyalty card is used with two credit cards it is useful to know it’s most likly the same family or even the same person?

      Wild speculation

        Even if they can see the owners name it’s not like they’re unique. Although doing simple correlation wouldn’t be that difficult.
