I think you're over reacting. RFID tags only have a range of centimeters. You'd need a huge current to power them from more than 1 meter, and that's just not going to be out on a beach in a hidden way. Since the coupling is magnetic a Faraday cage won't work. But a thin piece of mu metal would work pretty well. > The changes we are about to expect are moving the battle to another stage. > Let's get familiar with the new weapons about to hit the battlefield, and > devise the appropriate strategies. It's just for inventory control! They probably mount it on a tag you can rip off when you go to wear the clothing. The stuff you need to worry about is already out there as radio transmitters being planted by cops in your keyboard. The battle is already engaged, how's our defense look against real threats?
