PSD2 GLOSSARY:

AN OVERVIEW OF THE MOST COMMONLY USED ACRONYMS

Much has been said and written about PSD2, the revised  EU Payment Services Directiveit has become  a  particularly hot topic around September 14th this year, when the final part of the legislation officially entered into force. 

PSD2 brought a series of new abbreviations and acronyms with it, the most well-known of is probably SCAStrong Customer Authentication is perhaps the PSD2 aspect that mostly affected the general public, impacting also users’ online payment transactions. 

Along with SCA however, there are many more new acronyms used in the banking sector and beyond. To better navigate the various PSD2-related abbreviations, we have compiled a small glossary of the most frequently used terms.
