What is CVV Authentication?
CVV authentication, also known as Card Verification Value (CVV), is a security feature used to verify that the cardholder possesses the physical card during a transaction. It's a three or four-digit number printed on the back of credit and debit cards.
How Does CVV Authentication Work?
When you make a purchase online, the merchant requests the CVV number along with the card number and expiration date. The payment processor then verifies the CVV with the issuing bank to ensure that the card is present and not being used fraudulently.
Why Is CVV Authentication Important?
CVV authentication adds an extra layer of security to your card transactions. It reduces the risk of online fraud by ensuring that the person making the purchase has the physical card. This makes it harder for cybercriminals to use stolen card information to make unauthorized purchases.
