Hi Josh,
Thanks for the update. We are aware of that statement, however that only means that implementation is not compulsory. Seems it’s up to the individual banks (customers’ banks) whether or not they implement SCA2 starting 14 September, so merchants could be expected to see a rise in declined payments which is more or less severe depending on how many banks implement SCA2 on 14th September. There is no firm information on this, that we can see, but I can tell you that we are migrating clients to systems that can comply, Stripe being the favourite.
Thanks, Pat
