Hmmm, not sure how I came to post this under 'entertainment' but it is for real. I'll be getting my new card with 4 days. The fraud section of my bank (NatWest) said that it was most likely my card had been skimmed at a Filling Station ATM. It seems that the card details are sold on to buyers worldwide for as little as 50 cents to $5 for 'gold cards'.
Make sure you look at the card slot next time you use a cash machine.
