I'm not ready to subscribe to the RFID paranoia just yet, mostly because of the content D. Mindock provided. I have to feel their extreme capabilities are being over stated In regards to beef, it will be the Rancher who will be absorbing the cost of RFID implantation. As I understand it the tracking begins with the birthplace of the animal. Rancher or Feed lot will absorb all the costs, because the prices they get are set by the commodity markets Doug, N0LKK Kansas USA inc.
