To combat this, credit card companies have implemented various security measures, and one of the most crucial aspects of credit card security is the CVV.

What is CVV?

CVV is an additional layer of security that helps ensure that the person making an online or card-not-present transaction is the legitimate cardholder.

Types of CVV

There are two main types of CVV:

  • CVV1: This type of CVV is encoded in the card’s magnetic stripe and is used in card-present transactions, such as swiping your card at a physical store.
  • CVV2: CVV2 is the three-digit number found on the back of the card and is used in card-not-present transactions, such as online or over-the-phone purchases.

How Does CVV Work?

CVV is generated using a specific algorithm that incorporates the card number and expiration date. Since CVV is not stored on the magnetic stripe or the chip of the card, it sensitive cardholder information.

When making an online transaction, the merchant’s payment gateway will prompt you to enter the CVV along with the card details. The merchant then sends this CVV to the card issuer, who validates it against their records. If the CVV matches, the transaction is approved.

  • Visa and Mastercard: The CVV is a three-digit number found on the back of the card, usually on the right side of the signature strip.
