CVVkoodi

CVVkoodi, also known as Card Verification Value or Card Verification Code, is a security feature found on payment cards such as credit, debit, and prepaid cards. It is a three or four-digit number printed on the back of the card, usually alongside the card number. The CVV code is used to verify that the person making a purchase is in possession of the physical card. This adds an extra layer of security to online and telephone transactions, as it helps prevent fraud by ensuring that the card is not being used without authorization.

The CVV code is not the same as the card's expiration date or the three-digit security code (CVC) found on the front of American Express cards. It is a unique number that is generated when the card is issued and remains constant throughout the card's lifespan. In the case of virtual cards, the CVV code may be displayed on the screen instead of being printed on the card.

When making a purchase online, the CVV code is typically required along with the card number and expiration date. This information is usually entered into a secure form on the merchant's website. For telephone transactions, the CVV code may be required to be read over the phone to the merchant.

It is important to keep the CVV code confidential and not share it with anyone, as it can be used to make unauthorized purchases. If a card is lost or stolen, the cardholder should contact their bank or card issuer immediately to report the loss and request a new card with a new CVV code.
