"Petrol giant Shell has suspended chip-and-pin payments in 600 UK petrol stations after more than £1m was siphoned out of customers' accounts."
No comment on what they think the break might be, although I'd be more inclined to suspect that it's just a hidden camera (since it should be relatively easy to focus a camera such that you can see both the card number as it's inserted, and the PIN as it's typed in).

azz: Wired article on RFID security, or the lack thereof.
"Today, Grunwald continues to pull even more-elaborate pranks with chips from the Future Store. "I was at a hotel that used smartcards, so I copied one and put the data into my computer," Grunwald says. "Then I used RFDump to upload the room key card data to the price chip on a box of cream cheese from the Future Store. And I opened my hotel room with the cream cheese!""
Of course, what you actually want is an implantable RFID tag that's writable, so you can upload whatever you like it.
And yes, this means that you could pretend to be cream cheese if you wanted.
