In the financial world, American Express or AMEX is one of the most widely renowned names. If you have a credit card in your wallet, chances are you own a credit card that has a VISA or MasterCard seal in it.

MasterCard and VISA rely on partnerships from different banks in the world and do not issue a credit card of their own. What these companies do is they are simply selling their payment methods.

MasterCard and VISA charge their partners a fee for using the payment systems in order to make money. Both these companies do not issue credit cards. It is important to remember that VISA and MasterCard are only payment systems used by thousands of banks worldwide.

In American Express, they have both the payment methods and issue their own credit cards.

This means American Express runs everything and is independent from credit card companies like VISA and MasterCard. They don't need to rely on the payment systems of VISA and MasterCard because they already have their own payment systems for their credit cards.

VISA and MasterCard is by far, a more accepted payment method for a lot of people. This is because these two companies operate in around 20 million locations worldwide. However, American Express is more difficult to use because they still don't have the payment systems that these other two companies have.

But, American Express is now upgrading their payment systems and considering opening up payment methods in other countries.
