What is the importance of the security code on a Visa credit card?
How does the security code protect against fraud?
When making a purchase online or over the phone, the merchant will typically ask for the CVV code. This helps to verify that the person making the purchase actually has the card in their possession, as the code is not typically stored with the card number in databases. It makes it more difficult for fraudsters to use stolen card numbers to make purchases.
