I disagree, Amex cards have just the same security as any others. They also do not have VBV or any other verification. Not everywhere accepts Amex but most do and are easy to card with. But thats for online, should be the same in real time.Amex has a lot of security. Those are very hard to use. Mostly when they notice fraud, they either close the card and the dump is dead, or they tell the merchant to ask for zipcode.
But there are very good moments with Amex too. It all depends.
