This has not surprised me, actually surprised they don't make more use of it.
Tesco, e.g. you use your "Clubcard" so they have all your details, what you buy where, when etc. Don't htey see a pattern? Look at thousands of shopppers, even with out Clubcard they've got the PLU's on their system as they scan the stuff at the checkout. Yet we go to Tesco or on-line and they don't have what we want!
Appalling - no wonder they're losing the Supermarket race.
Thinks about it every time you shop/buy and use a card they know where you bought and what. The Banks could use this in conjunction with retailers to do some sort of marketing/deals.
Data Mining I call it. Again surprised there isn't more targeted stuff. Or better service.
Who will start doing this and win the race?
