We already have solid methods for identifying ourselves as the same person as we used to be (various public keys, for example), and if we want to establish a consistent identity across multiple contexts/domains, we also have that option. This really doesn't benefit consumers in any way.
As long as you need to access government services, I'd rather have them be efficient.
My country has had national IDs for close to a century, and they make life a lot easier for databases and programming :)
Strange, from my perspective, this seems like a negative result.
I cannot convincingly prove that I entered any work agreement I did online.
I cannot proove anything anyone committed to online.
Giving any binding signatures online or via mobile?
Any official communications with government services where both sides need to know who the other is, not just who they say they are?
Legally binding online agreements between private parties?
The level of tracking and privacy violations online is already disturbing and downright creepy
This would take it to a whole new level.
There are other bad things possible, for example, I can already see Media Industry lawyers rubbing their hands, tie National ID cards to ISP database and overnight suing people would become easier.
One for the entity managing your retirement funds, one for the national healthcare, one for the tax filing, one for requesting a certificate etc, one for filing a request with the police etc, one for the city council services, one for the district, one for the region, one for the university, one for the separate agency that manages scholarships etc.
I am, honestly, listing the ones I had to cope with. In my country, each entity manages their own system, with different bugs, varying level of security and screw ups, incompatible data, delays of up to two weeks to receive a PIN when signing up for a new service and the occasional "wait, you are not supposed to exist" moments.
I'd take a unified, compatible multifactor auth system like the estonian one every day. Heck, there was even an OpenID bridge some years ago!
EDIT: it's still up apparently
