what is cvv in atm

The CVV, or Card Verification Value, is a unique security code, typically a three-digit number, printed on the back of your ATM or debit card, near the signature strip. It is an essential feature for card-not-present transactions, such as online shopping, as it adds an extra layer of security. The purpose of the CVV is to confirm that the person making the online payment has physical possession of the card. It is crucial not to share this confidential number with anyone, as it is different from your ATM PIN, which is used for in-person cash withdrawals or payments.
