In the context of electronic commerce and digital financial transactions, CVC stands for Card Verification Code (also commonly referred to as CVV or Card Security Code). It represents the security feature consisting of a three- or four-digit numerical code printed physically on credit or debit cards. The primary purpose of a CVC payment verification check is to ensure that the person initiating an online or remote transaction is in physical possession of the card, thereby adding an extra layer of fraud prevention during digital checkouts.
