I also have been the victim of credit card fraud, about a year or so ago. Had my credit card 'cloned' and several transactions made on it. The incident was sorted out after some time but a great hassle! Since then I have always used cash, but I agree that some hotels require a swipe of a credit card on check-in. I now have what I believe the perfect answer, which has worked every time since. I have a 'pre-paid' Mastercard credit card with a few pounds on it, and use that every time I am asked for one at check-in. If they cloned that one, it wouldn't be much of a problem!!
