Understanding Visa’s EMV 3D Secure program
Blog post from Evervault
EMV 3D-Secure (3DS) is an advanced version of the original 3D-Secure protocol developed by VISA to combat payment fraud in online transactions while maintaining a streamlined user experience. By leveraging risk-based analysis and advanced authentication methods, such as biometrics and one-time passcodes, EMV 3DS aims to reduce fraud without causing excessive disruptions to the payment process. The protocol involves three main components—Directory Server, Access Control Server, and 3DS Server—that facilitate either a frictionless flow for low-risk transactions or a challenge flow for those requiring additional verification. Mandated in Europe under the Strong Customer Authentication component of the Revised Payment Service Directive, EMV 3DS shifts liability for chargebacks from merchants to card issuers, offering merchants protection against fraud costs. The evolution of the protocol, backed by EMVCo, has improved user experience by supporting mobile-first designs and digital wallet payments, and future developments may further integrate AI and IoT support to enhance security and convenience.
