Can you explain how credit card payment works?

Credit card payment works by allowing cardholders to make purchases using a line of credit provided by the card issuer. When a purchase is made, the cardholder is essentially borrowing money from the issuer. The cardholder then has a grace period to pay off the borrowed amount in full or make a minimum payment. If the full amount is not paid, interest is charged on the remaining balance. The cardholder can continue to use the card up to their credit limit as long as payments are made on time.
