I don’t like being a long toothed payment historian…. So please pardon my reluctance here… and let me know of any errors.

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.
