What is the full form of CVV
CVV: Card Verification Value
CVV stands for Card Verification Value. It is a security feature provided by the banks in credit, debit, and ATM cards. It is a combination of three digits or a three digit number printed on the reverse of your credit/debit cards on the right side of the signature strip. Its purpose is to establish owner's identity and minimize the risk of fraud during online transactions. It is also known as card verification code (CVC) or card security code (CSC). On American Express cards (AMEX), it is usually a four-digit number on the front of the card.
CVV is not embossed unlike the card number and not printed on any receipts so that it is not known by anyone other than the cardholder. A credit card company may have its own name for CVV code, e.g. VISA calls this code CVV2, MasterCard calls it CVC2 and American Express calls it CID.
CVV number is different from the PIN (personal identification number) of your card. So, never enter your PIN number when you are asked to enter your CVV number. Where you can present your card like while shopping at malls or paying bills at restaurants you use your PIN number. CVV number is required while you shop online or make online payments as here you cannot present your card.
