what is cvc in atm card

The CVC (Card Verification Code), also widely known as CVV (Card Verification Value), is a crucial three-digit security feature found on your ATM or debit card. It is typically located on the back of the card, on the right side of the signature strip. Its primary purpose is to authenticate you as the genuine cardholder during 'card-not-present' transactions, such as online shopping. Requiring the CVC verifies that the physical card is in the buyer's possession, which helps prevent unauthorized use if your card number is compromised.
