3D Secure

Definition

3D Secure is an online payment security protocol that adds an additional layer of verification for card-not-present transactions, aiming to reduce fraud and chargebacks during e-commerce transactions. It typically involves redirecting users to a bank page for authentication, where they may be required to enter a password or a code sent to their mobile device. This process not only enhances security for consumers but also helps merchants in mitigating risks associated with fraudulent activities.

5 Must Know Facts For Your Next Test

1. 3D Secure was initially developed by Visa under the name 'Verified by Visa' and has since been adopted by other card networks like Mastercard (Mastercard SecureCode) and American Express.
2. The protocol allows merchants to shift liability for certain types of fraudulent transactions from themselves to the card issuer, which can protect them financially.
3. There are two versions of 3D Secure: 1.0, which relies on static passwords, and 2.0, which utilizes risk-based authentication and provides a smoother user experience.
4. 3D Secure can help improve transaction approval rates as issuers are more likely to approve transactions that have undergone additional verification.
5. The integration of 3D Secure may require technical adjustments on the merchant's website or app, impacting the overall checkout experience if not implemented seamlessly.

Review Questions

• How does 3D Secure enhance the security of online transactions compared to traditional payment methods?
  • 3D Secure enhances online transaction security by requiring an additional layer of authentication that goes beyond just entering card details. This usually involves redirecting customers to their bank's website to verify their identity through a password or one-time code. By implementing this step, it significantly reduces the risk of fraud and chargebacks since unauthorized users are less likely to have access to these additional verification methods.
