This white paper from the researchers and compliance specialists at Daon seeks to clarify, in layman's terms, the most salient points from the European Banking Association's (EBA) June publication on the elements of PSD2 Strong Customer Authentication (SCA), with particular attention paid to how certain existing authentication approaches do (or do not) fulfil SCA requirements, and how the potential for case-by-case deadline extensions will impact the e-commerce market’s general preparedness for PSD2.
