3D Secure Does not Work with SecurePay Even if Payer Authentication is Enabled in NetSuite

Aside from SecurePay's FraudGuard, it also offers another service called Payer Authentication or what is more commonly known as 3D Secure.

This service can be enabled in NetSuite by marking the  Payer Authentication box on the Credit Card Processing Profile page (Setup > Accounting > Credit Card Processing). Once enabled it redirects shopper to a payer authentication site (Verified by Visa or MasterCard SecureCode).

However, please note that right now it is not yet supported with NetSuite's integration with SecurePay.
