3D Secure

Definition

3D Secure is an authentication protocol designed to provide an additional layer of security for online credit and debit card transactions. By requiring the cardholder to complete a verification step, such as entering a password or a code sent to their mobile device, it helps reduce fraud and chargebacks in e-commerce. This protocol is widely used by merchants and banks to ensure that the person making a purchase is indeed the cardholder.

5 Must Know Facts For Your Next Test

1. 3D Secure is commonly recognized by its branded names, including 'Verified by Visa' and 'Mastercard SecureCode', which help consumers identify the program during checkout.
2. This security protocol is designed to reduce the risk of online fraud by verifying the identity of the cardholder before the transaction is completed.
3. When a consumer makes a purchase using 3D Secure, they may be redirected to their bank's website to enter a password or code for authentication.
4. The implementation of 3D Secure can lead to increased approval rates for online transactions as it assures merchants and issuers that the transaction is secure.
5. 3D Secure 2, an updated version of the protocol, incorporates risk-based authentication, allowing for a smoother user experience while maintaining security.

Review Questions

• How does 3D Secure enhance online payment security compared to traditional credit card transactions?
  • 3D Secure enhances online payment security by adding an extra layer of authentication beyond just entering card details. When a consumer makes a transaction, they are prompted to complete additional verification steps, such as entering a password or receiving a one-time code. This process ensures that even if someone obtains the card information, they cannot complete the transaction without the necessary authentication from the legitimate cardholder.
• Evaluate the impact of 3D Secure on online merchants and consumers regarding transaction approval rates and fraud reduction.
  • The implementation of 3D Secure has positively impacted both online merchants and consumers by increasing transaction approval rates and reducing instances of fraud. Merchants benefit from knowing that transactions have been verified, leading to fewer chargebacks and losses from fraudulent activities. For consumers, this added layer of security builds trust in online shopping experiences, making them more likely to complete purchases when they feel their financial information is protected.
