I have been hoping for a GPS chip for the dog, but I think chipping people (not GPS, just information) is a good idea in certain ways although I do understand the prophesy as well as people feeling like the government is taking over their bodies. I am an ED nurse and I think being able to scan a patient when they come in and get a complete medical history, medications, allergies, etc would be most helpful, especially if that patient was unconscious or otherwise unable to convey that history. Where I live, people dont often have a good understanding of their medical history nor know their medications.
