I'm researching for a soon to appear article about RFID. One interesting sidebar is about disabling RFID tags in passports or credit cards. Devices for such exist, but I can't find any information about the legalities of such an action. Has anyone spotted some good sources online?
BTW, whatever you do, don't use a microwave to kill embedded RFID tags. Yes - it will destroy the tag - along with the material in which it's installed. It may also damage your microwave.
