My question with that is one of usability. Where I live our ID has digital certifications in it and you can theoretically use it for online authentication. It's just a mess of a system, so people tend to pick other options.

I mean, it works... it's just that it's hard enough to use that you often are given alternative tools for verified ID and most people use those because they're more convenient than the solution that is meant to be the convenient standard. It's a once and future XKCD strip.

The authenticated, secure, universal ID card is pretty handy still, though.
