EMV 3-D Secure
EMV 3-D Secure, often referred to as 3-D Secure 2.x, is the authentication
protocol provided by the card networks to support SCA. To comply with SCA, merchants
must deploy 3-D Secure 2.x to their checkout page or use a compliant hosted
checkout.
Additional data can be passed in now and is automatically sent to issuers as
they upgrade to 3-D Secure 2.x. The payer authentication service is also
backward-compatible with 3-D Secure 1.0.
