But let us not forget that it took the Danish Government two tries to get it right. First they tried to push digital signatures on everyone, with the idea that people should use their personal certificate to login to banks and government systems. However the banks would have none of it, because of the bad user interface (ever tried to use client-side certificates in any browser). They then adopted a system that was a mix of systems already in use by a number of banks. Key-cards to be distributed by snail-mail and entered trough a Java plugin. Why they didn't go for a Javascript solutions is sad, but I would guess that some banks (such as Danske Bank) would have trouble adjusting. So the lesson is probably that (some) governments are good at standardizing already (good) practices. PS: Also note that some Companies (like Telmore, one of the largest online shops), who offered the old system (client-side certificates), won't use the new because of the absurd cost associated. (They have to pay per registered user, not by how much each user is using the system)
