But yes in e.g. banking the security systems had been created long before there where really good USB based security keys so it's probably most times actual smartcards.

But then it also turned out that many smartcatd drivers are just REALY bad and complex potentially making your system more vulnerable so I can totally see companies switching away from them.

I would link to a feature matrix, but Yubico makes it impossible to find one (although I know it exists).
