RFID chips are being used more and more in health care. Today the main use proposed is to track whether you receive "authentic" or "fake" medications. The US pharmaceutical industry wants to track whether or not we take and refill brand-name medications. But this is a huge intrusion into the relationship we have with our doctors. If you don't want to take a medication for whatever reason: side-effects, costs, fears, feeling it does not work, etc------the person to discuss this with is your doctor, not a drug company! There are many valid reasons to change or stop medications. The only people qualified to decide whether you should stay on a particular medication or not are you and your doctor.
