American Express cards are issued by American Express, a publicly traded financial services company, and are payment cards, credit cards, or prepaid cards.
An American Express card, also referred to as an “Amex” card, may offer a variety of benefits, including reward points, cash back, and travel benefits. Some cards are joint, for example, with Delta and Hilton.
American Express is one of the few card companies with a network to process card payments. Visa and Mastercard have processing networks but do not issue cards.
