I mean, why bother with the loyalty card? Can't they just track the payment (debit, credit) card?
The loyalty card lets them track cash payments made by you as well.
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.
