American Express cards

American Express cards are the most special ones issued in the U.S. By that I don’t mean that AmEx’s card programs are all that different from their competitors’. Well, perhaps some of them are, but other issuers have programs that are so similar that you would not be able to tell them apart, unless you saw the brand logos on the terms and conditions disclosure.

The uniqueness of American Express cards can be found in some of the security features on their cards. In this post I will review these features and will explain how to recognize their validity.
