I have no plans to travel overseas, and to protect my credit card from being charged falsely, I called and asked them to block any international charges. They said it is not allowed, but if I get a charge I do not have to pay, and they will change my cc number. I do not want to go through this hassle. I did have a charge from the UK, but it was for $11. If it happens again, I will change my card number. I would think that it would be easy to block any charges outside the USA. User's recommendation: If you plan on traveling, use a different card. Once you get home, you could still see charges you did not make.
