This is likely to be phased in. Chip will be implanted at birth. For adults it will be a choice, no government check if no chip, or no National Health Service if no chip.
Will take another generation before U.S. does it.
BTW, anyone else remember the chortling that Big Media did about how Tim McVeigh was ranting about RFID chips to be implanted in humans? "Ho, ho, ho, could never happen, proves how loony those people are, heh, heh, heh."
