UPDATE – Nov 29 2022 – Note that I have conflated the relationship between SRC and 3DS 2.0. 3DS 2.0 is the authentication protocol used by SRC. 3DS 2.0 has been widely adopted as a mandatory replacement to 3DS 1.0. Part of the driver for adoption was the EU SCA mandate. SRC has NOT been widely adopted as it is a fairly broken consumer experience at the moment. 

I’m at M2020 today and it has been a “back to normal” fantastic event. Let me put my “merchant hat” on for a story from their perspective.
