Have you handed that card to shop staff where they've said, 'oh, i'll just fetch the machine ...'
I'm sure thats not the only clone route.
My mate once went for some petrol paid on his card handed the receipt but the woman kept the card receipt. He asked for it she made up some story why they kept them. He worked for a bank at the time , told her hand it over or I call the police. So still standing in the shop he phoned them explained what was going on. They arrived and sorted it they went on to investigate and it turned out she'd a thing going and was passing them on to card cloning gang.
and something chocolatey.
