This document provides information about credit cards, including:
- A credit card allows the holder to buy goods and services with the promise to pay the issuer later. Most are issued by banks and are made of plastic.
- Credit cards originated in the 1920s and became widely used starting in the 1950s and 1960s with the creation of Diners Club and other general purpose cards.
- Credit cards work by verifying funds during purchase and sending the customer a monthly statement to pay. Interest is charged if the full balance isn't paid. Customers receive rewards while merchants pay fees for each transaction.
