Likewise. The point being, handing everyone in IETF an RFID tag probably
doesn't have new privacy implications for most of them, and giving them a
faraday cage, as was done in Hiroshima, addresses the remaining implications
for those people who do not carry powered-on cell phones or laptops for privacy
reasons. If you carry a powered on cell phone, I don't think you can argue
that carrying an RFID tag with a simple number in it makes things any worse.
Actually, the main argument I'd make against IETF RFID tags is that it's more
plastic to throw out.
