A credit card is a financial tool that allows the cardholder to borrow funds from the issuer, typically a bank or financial institution, up to a specific credit limit. The cardholder can then use the card to make purchases or withdraw cash from an ATM, understanding that they will pay back the borrowed funds, plus interest, at a later date.
Credit cards are widely accepted as a form of payment and can be a valuable tool for managing finances, but they can also lead to debt if not used responsibly. Some credit cards also offer rewards or cash back for certain purchases.
