Secure version 2 is an evolution of the existing 3-D Secure version 1 programs: Verified by Visa, Mastercard SecureCode, AmericanExpress SafeKey, Diners/Discover ProtectBuy and JCB J/Secure. It is based on a specification that has been drafted by EMVco. EMVCo exists to facilitate worldwide interoperability and acceptance of secure payment transactions. It is overseen by EMVCo’s six member organizations—American Express, Discover, JCB, Mastercard, UnionPay, and Visa—and supported by dozens of banks, merchants, processors, vendors and other industry stakeholders who participate as EMVCo Associates.
One of the core differences in version 2 is that the issuer can use a lot of data-points from the transaction to determine the risk of the transaction (risk-based analysis). For low-risk transactions, issuers will not challenge the transaction (e.g. not sending an SMS to the cardholder) although authenticating the transaction (frictionless). Inversely, for high risk transaction, issuers will require the cardholder to authenticate with an SMS or biometric means (challenge).
Separately the Strong Customer Authentication (SCA) required in Europe by September 14th, 2019 as specified in PSD2 will result in a substantial increase in the number of transactions requiring the use of 3-D Secure authentication. The use of 3-D Secure version 2 should limit the potential negative impact on conversion as much as possible. In short 3-D Secure version 2 means:
- You will need to implement 3-D Secure before September 14th, 2019 if your transactions fall within the EU PSD2 SCA guidelines (in case you don't already support 3-D Secure).
- You are advised (and for some are required) to submit additional data points to support the risk assessment performed by the issuer in case of 3-D Secure version 2
- A much better user experience for your consumers
The expectation in the market is that a substantial percentage of transactions using 3-D Secure version 2 will follow the frictionless flow, which doesn't require anything additional from the cardholder compared to current non-3-D Secure checkout flows. This means that you benefit from the increased security and liability shift that is provided by the 3-D Secure programs, while the conversion in your checkout process shouldn't be negatively impacted.
