Credit card transactions are protected by the credit card company. The burden is on the establishment to prove that it was legit. If not, the credit card company issues a chargeback to the establishment and the card user is off the hook. American Express is the toughest to do business with and they are the best when it comes to the user. I'm not going to share what I do for a living, however I take 6 digit loses in my business annually and clearly know how this works. The vast majority are fraud..... Organized crime being the biggest culprit.

Feel free to email your credit card info. If you need piece of mind use a different card than you plan to travel with in the rare event your card is compromised.
