Tagging Everyone at Birth to Control Everyone’s Life … & Death

That is the newest futuristic idea on BBC Future by Sci-Fi novelist Elizabeth Moon: “If I were empress of the Universe I would insist on every individual having a unique ID permanently attached – a barcode if you will…
“It would be imprinted on everyone at birth…
“Having such a unique barcode would have many advantages. In war soldiers could easily differentiate legitimate targets…”.

This is the best answer I read, by Christopher Akritidis in a Facebook comment: “Why bother with half-measures? What we need is an implant that can function as a GPS, that transmits data from all our senses along with our emotions and that can release endorphins or deliver small electric shocks. Oh, and we definitely need a cool, ‘instant kill’ button… just for those pesky terrorists, you know… so you can all feel safe, warm and fuzzy inside, all the time”.
