What is CVV Test 3D Secure?
The CVV test, also known as the Card Verification Value test, is a security feature used to ensure that the person making a transaction has physical possession of the credit card. 3D Secure, on the other hand, is a security protocol introduced by major card networks like Visa and MasterCard to provide an additional layer of protection for online transactions.
How Does the CVV Test Work?
During the CVV test, the system verifies the CVV number printed on the back of the card. If the CVV number matches what is on file with the card issuer, the transaction is approved. This helps prevent unauthorized use of the card.
Understanding 3D Secure
3D Secure adds an additional step to the checkout process, where the cardholder is prompted to enter a password or use a one-time passcode. This ensures that the person making the transaction is the legitimate cardholder.
