Verified by VISA, SecureCode Mastercard, 3 D Secure 2.0

Discover how 3-D Secure secures card-not-present payments through a three-domain messaging protocol, clarifying issuer, merchant, and card scheme roles and the card-present vs not-present distinction.

Explore the three domains of 3D secure—acquirer, interoperability, and issuer—and how they secure transactions through acquirers, issuer banks, and card schemes.

Explore the 3-ds domain transaction flow, where the issuer, network, and acquirer authenticate the cardholder using Verified by Visa and Mastercard Secure Code before payment processing.

Explore the key terminologies of 3D secure: 3D requester, 3DS server, issuer ACS, interoperability directory server, merchant plugin, and 3DS 2.0 improvements for frictionless authentication.

Explain how a cardholder initiates a transaction and how enrollment is verified. Describe authentication at the ACS via OTP or biometrics and how the response enables settlement.

Explore how the 3DS transaction flow secures payments: from Verified by Visa entry, through merchant and issuer verification, risk assessment and potential challenges, to authorization and fraud filtering.

Explain the transaction logic of 3DS 1.0 and 2.0, including how enrollment affects authentication, authorization, and settlement via issuers and card networks.

Explore the transaction logic flow in tdrs 2.0, where the merchant or acquiring bank chooses redirect to the secure system or direct authentication with verified by Visa and Mastercard prompts.

Under 3D Secure 2.0, liability shifts from merchant to the issuer bank, as authentication happens on the issuer page with data points shared to reduce fraud and chargebacks.

Explore emv 3ds 2.0, a mobile-first secure authentication standard that reduces fraud with more data points and issuer-based risk checks, helping merchants meet strong customer authentication in the European Union.

Show how card networks use different names for the same EMV authentication system—Verified by Visa, Mastercard SecureCode, CFT by American Express—while the underlying process remains standardized.

Learn how 3D Secure adds authentication to card payments and reduces fraud. See how Stripe Radar and a single API call manage high-risk, recurring, and offline payments.

This lecture compares 3D Secure 1.0 and 2.0, showing 2.0's elimination of static passwords, use of otp or biometrics, expanded data points, guest checkout with card on file, and tokenization.

This lecture explains how 3D Secure 2.0 collects data points—from expiry date and purchase amount to device and merchant details—to improve issuer decisioning and secure e-commerce transactions.

3D Secure 2.0 shifts liability to issuer bank, increases approval rates, reduces fraud and disruptions for customers, merchants, and financial institutions, and supports biometric and two-factor authentication for seamless payments.

Explains how 3D Secure 2.0 and PSD2 mandate strong customer authentication for electronic payments, detailing the three factors and two-factor requirements with exemptions.
