Depends on which country you are in. Your bank card in some European countries is not allowed to receive or store info about the items you purchased, but the shop obviously will and there is a limit on what they can do with that info and for how long they can store it.
So if I pay for petrol with a card and also buy donuts and coffee the bank and the shop cannot market to me according to what I bought, but if I join a loyalty card scheme then I'm opting in and the shop can, but not the bank.
In Norway btw, where govt. are strict about this sort of thing.
