What’s the best way to nullify the tag?
Normally, when I am asked how to kill an RFID transponder, I suggest hitting it with a hammer or putting it in a microwave oven. These strategies won’t work with an implant, however. To kill a tag, you need to overload it with energy and blow its circuits. These circuits are tiny, so even static electricity from your finger can blow them, as long as you are able to touch the chip directly. The problem with an implant is that you can’t touch it, so you can’t get the electricity to the transponder. You could try shocking the area around the skin by attaching wires to a 9-volt battery and touching them to the area of the implanted RFID transponder, but I suspect that the electricity would flow through the skin cells and not reach the implant in the subcutaneous tissue (I have never tried this, so I don’t know for sure). The best option would be to visit a doctor and have him or her remove the device.
