A "💳" is a small plastic card issued by financial institutions that allows individuals to make purchases on credit. It typically bears the name of the cardholder, a unique account number, and an expiration date. Credit cards provide a convenient and widely accepted method of payment, enabling users to borrow money from the issuing institution to pay for goods and services. Transactions made with a credit card accumulate as a balance, which must be repaid either in full or through monthly installments, often with added interest charges.
