What does cvc mean on a debit card?

CVC stands for Card Verification Code, which is a security feature on debit and credit cards. It is a three-digit number printed on the back of the card (or four digits on the front for American Express cards) and is used to verify that the card is in the possession of the cardholder during online or card-not-present transactions. This helps to reduce fraud and ensure the security of the transaction.
