What approach did John Mosquera take to implement strong customer authentication (SCA) for European transactions in the Stripe system?
assistant
John Mosquera implemented strong customer authentication (SCA) for European transactions by leveraging Stripe's 3D Secure 2 integration. He set up dynamic detection of transactions requiring SCA based on the customer's location and transaction characteristics. John implemented a frictionless flow for low-risk transactions that could be exempted from SCA. For transactions requiring authentication, he integrated a seamless 3D Secure flow into the checkout process. John also implemented fallback mechanisms for cases where 3D Secure might fail. He created detailed logs and analytics to monitor SCA performance and exemption rates. Additionally, John conducted thorough testing to ensure compliance with PSD2 regulations. John successfully implemented strong customer authentication for European transactions using Stripe's 3D Secure 2, with dynamic SCA requirement detection, frictionless flows for low-risk transactions, seamless integration into the checkout process, and fallback mechanisms. This comprehensive approach ensured compliance with PSD2 regulations while maintaining a smooth user experience.
