Non jingling non stabbing key holder

[kbalch]

RFID technology didn't really make me nervous until I read about "RFID dust". Also called "RFID powder" or "smart dust".

All sorts of surveillance applications for this stuff. It brings the old-school "brush pass" into the 21st century, nevermind the ability to shoot/project/spray it at a target or apply it to something you know the target will touch. You only need one mote to adhere and you own that target's every move. Countermeasure aside, of course.
