What technology does the dCVV/CVC3 utilize?

The dCVV (dynamic Card Verification Value) or CVC3 enhances the security of card-not-present transactions by utilizing public key/private key technology. This technology is designed to provide an additional layer of security beyond traditional static card verification methods.

In this system, a unique code is generated for each transaction, which is tied to the cardholder's account and can only be validated using the issuer's public key. This means that even if a payment is intercepted by a fraudster, they cannot use the dCVV for a different transaction since it will only be valid for a specific transaction, unlike static codes which can be replicated and reused.

This approach is crucial in mitigating risks associated with online payments, where static credentials are often targeted by attackers. The use of public key infrastructure (PKI) ensures that sensitive information is encrypted and securely transmitted, thereby reducing the likelihood of fraud.

Other options such as magnetic stripe technology involve more traditional, static methods of payment and do not provide the dynamic security that dCVV offers. Static encryption only would not adapt to each transaction, and biometric authentication, while useful in certain contexts, is not the technology employed in the creation and validation of dCVV. Therefore, public key/private key technology is essential for the
