Interesting! Why does the distinction of a country matter here? I mean - why would using client side certs be something a country as a whole uses, as opposed to a certain type of company or something? Does it have to do with some sort of national firewalls or anti-encryption laws?
It has to do with widespread deployment and a central trust authority - that the specific citizen holding the specific citizen's cert. Service providers don't have to deal with the massive pain that is identity verification, there's no cumbersome stuff like faxing someone a gas bill to prove their identity.
