CVV2 (Card Verification Value 2) is a 3-digit code printed on the back of all newer Visa cards. In the physical retail world, merchants are practically guaranteed funds from their credit card transactions, primarily due to customer authentication during the approval process. When the merchant physically swipes the credit card through the magstripe reader on the terminal, the sale will qualify as "Visa CPS Retail" and because it is assumed that the merchant will compare both the signatures and the embossed account numbers, the cardholder is considered "authenticated".
