Strong Customer Authentication or SCA: is Europe 3D secure (2.0)-Ready?
As part of a European Union mandate called the Revised Directive on Payment Services, or (PSD2), merchants operating in the EU economic zone must use payment service providers within the European Economic Area that offer what is known as strong customer authentication.
This is also sometimes referred to as the SCA requirement or the PSD2 compliance. In essence, this directive ensures that transactions occurring within the EU’s economic territories make use of multi-factor authentication in order to verify a buyer’s identity.
