Yet someone already had and also had it approved, by the medical authorities for starters.
Actually it’s something like the chips implanted at the back of the neck of our pet dogs and cats.
In a very short while we’ll have one implanted ourselves, instead of passports/ID cards/drivers licenses. Only we’ll have it screwed tight someplace, so that it will be considered difficult to remove. And very soon afterwards some ‘surgeons’ will become so adept at ‘hacking’ that they’ll be able not only to provide you with a new identity but also to screw it inside your body, in place of the old one.
