I downloaded this app: https://play.google.com/store/apps/details?id=com.bluetoothscanner to test the claim that the vaxxed emit a Bluetooth signal.
Sure enough, when near the vaxxed, you get Mac addresses, and it seems it can detect signals from quite a distance (potentially up to 20 Meters) The thing is, I can't verify if it's from their mobiles or their bodies. I am not on very intimate terms with any of the vaxxed so I can't ask them to go with me to a secluded place away from people without their phone to check if it's them.
I tested to see if the app will still show random Bluetooth addresses when away from people or any devices and sure enough it does not. So the app is not just generating some random numbers.
I think the vaxxed emitting a signal is possible, it's just that not many people tried to test it out, because everyone thinks: "It's so easy to test, surly we would have known by now!!" Please share your input so we can settle this once and for all!!
I had wondered too about the uniqueness aspect, how they could ensure it. There must be some random number generator in the nano device, one of sufficient knowable assignment to ensure no two people get the same id. Or in the manufacturing process, they add to each vial a nano with a unique code, in this way giving every vial uniqueness. Or, they add a standard nano and then program it in the vial on the manufacturing line, with an RF burst or something. I think that third case is the likely way.
This is easy to achieve using cyclical cyphers with a common key gen. RFA tokens for instance
