Are ID cards enough could we go further?

why stop at ID cards, we love our pets wether they be dogs, cats,horses, etc. and to protect them and to identify them if they are stolen or lost, we Micro chip them, well there is the answer micro chip all babies at birth, forget ID cards, and give the parents of children some piece of mind, after all some 20,000 people go missing around the world every year, and its also true a good deal of them disapear of their own accord, however there are a good number who just get lost, or like the madeline case are abducted against their will, now madeline had one well known defect in one eye, but thousands of children would all look very similar to the average person in the street however airport and border scanners could be modified to detect the chip if anyone was trying to remove a child or a person for that matter, from a country when have no legal right to do so, now my guess is this question will have all you lefties and human rights people setting your keyboard on fire, so lets hear it
