are the facial image and fingerprints only used for background check, are they stored (and for how long) and are they shared with different entities, such as police or foreign governments?
they store it in citizen database. as of now they do not share the fingerprints with our regular police. the face they probably get.
I think that our local spy people have access to them (there was a theory about them managing our offshore database backups and therefore never asking for anything); if and how they share it is not disclosed.
foreign governments might get access through travel information agreements (biometric passports were a requirement for free travel to US) but I am not certain about those details.
Wouldn't this kind of ID be granted to anyone, so long as they are who they say they are, so long as their identity is vetted.
I think selectively doling out benefits or rights is the job of a separate system. (And if everyone has one of these IDs, the design of the second system could be simpler than it might be otherwise. I think.)
