How does Radar use Dynamic 3D Secure?

• A. Radar sends high-risk payments through Dynamic 3D Secure
• B. Radar disables 3D Secure for fast checkout
• C. Radar uses 3D Secure only for low-risk payments
• D. Radar replaces 3D Secure with passwordless authentication

Answer: (A)

Dynamic 3D Secure applies 3D Secure authentication only when a payment is deemed risky. Radar analyzes each transaction and flags high-risk ones, then triggers the Dynamic 3D Secure flow so the cardholder completes an additional verification step. This conditional approach adds security where it’s most needed while keeping low-risk payments flowing smoothly. That’s why saying Radar sends high-risk payments through Dynamic 3D Secure best describes its behavior. It doesn’t disable 3D Secure for fast checkout, and it isn’t limited to low-risk payments—the whole point of dynamic use is to apply 3DS to the transactions that need it. It also isn’t about replacing 3D Secure with passwordless authentication; the flow remains within the 3DS framework when triggered.
