What Is a Credit Card?

A credit card is a payment card issued by a financial institution, typically a bank or credit union, that allows the cardholder to borrow funds to pay for goods and services. The cardholder agrees to repay the borrowed amount, either in full by the due date or over time with interest. Credit cards are linked to a revolving line of credit, meaning the available credit replenishes as payments are made.
