That looks really interesting. But, the government will hold a lot of information about their citizen, how they will use that? I do not know if something like this could be replicated in every country.
Exactly the way they've already announced that they'll use it: To collect tax.
You ask, how they will use that? They don't much use what they already have, so the best guess is that there will be no use. Which is pity, since it can be used for a lot of good. But I guess you would say it is lucky, since it can be used for a lot of bad.
