The same thing is happening in Greece. The new mandatory digital ID replaces and unifies everything about citizens in one place, "to make it easier for government services to share information between each other". It can indeed be useful, but the privacy implications are enormous. Just imagine that a policeman, employer or anybody else with access to the information linked to the ID can instantly view our medical records, tax status and even simpler things like if we've ever been caught driving while drunk. Nobody knows what other information could be attached to it, but it's certain that it can be used to discriminate against us.
The worst part is that we no longer have any power to do something about it. Eventually, after it goes through the testing phase in the UK and Greece (and a few other countries where it's being implemented), this will probably roll out on a global scale, making privacy impossibly. I'm starting to get this feeling that in the next decade, we'll be living in 1984...
