American Express

American Express is a global financial services company that provides charge cards, credit cards, and payment products for consumers, small businesses, and large corporations. It operates a closed-loop payment network, meaning it acts as both card issuer and merchant acquirer, giving it direct control over transaction processing and merchant relationships. The company offers services including rewards programs like Membership Rewards, travel booking through American Express Travel, and business tools such as expense management and working capital financing. Its consumer and business card products range from no-annual-fee cards to premium offerings like the Platinum Card, often bundled with travel benefits, purchase protections, and airport lounge access. Beyond card issuance, American Express provides merchant services that enable businesses to accept card payments and access customer insights and marketing support.
