Way to go SRS! I've wanted to know how to do that for a while now!
Problem with technologies that can end up costing us our liberties is how they begin utilization. The dog chip thing seems great. Our local animal shelter scans every animal brought in and has an almost perfect rate of recovery for those pets with chips.
(Tattoos work this way also. Of course THAT makes me think of the camps of the Third Reich, which used tattooing extensively.)
But it is a short step to "chipping" your child, to "chipping" all of us. To being able to find a person no matter where they are.
Wasn't there a film recently where one's chip was also a dedicated "explosive" device which could terminate you should you comitt an offense?
(thread drift - back during the Gulf War our local supermarket still asked if you wanted "paper or plastic" I would answer: "That depends on whether I wish to save a tree or a Marine, doesn't it?"
