what is meant by cvv in atm card

CVV stands for Card Verification Value, also known as the Card Security Code. It is a mandatory 3-digit security code printed on the back of your ATM or debit card, usually near the signature strip. This unique code is essential for authorizing online transactions and purchases made over the phone. It acts as an additional layer of security to ensure that the person conducting the transaction has physical possession of the card, protecting against fraud even if card details are stolen.
