A credit card is a plastic card issued by a financial institution that allows cardholders to borrow funds to make purchases or pay for services, up to a predetermined credit limit. Unlike debit cards, which deduct funds directly from a linked bank account, credit cards enable users to borrow money from the issuer with the understanding that they will repay the borrowed amount, typically on a monthly basis. Credit cards offer convenience, security, and flexibility in managing expenses, and they often come with various features such as rewards programs, cashback incentives, and travel benefits. Users are required to pay interest on outstanding balances if they do not repay the full amount by the due date.
