what is a cvv on a debit card

A CVV (Card Verification Value) on a debit card is a 3-digit number on VISA, MasterCard, and Discover branded credit and debit cards, and a 4-digit numeric code on American Express branded cards. It is a security feature that helps prevent fraud during online or phone transactions. The CVV is not the same as the cards PIN (Personal Identification Number) and should never be shared. It is typically located on the back of the card, but in some cases, it may be found on the front. The CVV adds an extra layer of protection to confirm that the cardholder is the one using the card, and merchants are required to protect this information and delete the CVV number after the purchase is authorized. Some banks issue credit and debit cards with dynamic CVVs, which change frequently to enhance security.
