It has been a while[1] since I last wrote about RFID. The most recent article I have read on the subject is substantially more of a concern than the others that show up in the recent history if you search "Random Unfinished Thoughts."[2] This is because I now read about tagging people, not products or even documents.[3] This takes the idea of biometric authentication to a new and highly disturbing level. Notably, it combines the worst aspects of biometrics' hard-to-deny with RFID's easy-to-covertly-read. Thus if it ever does prove forgable, as is rather likely, as it would be a purely technical matter of reverse engineering the chip inside, you will have a particularly nasty sort of identity theft.
The pluses for those wishing to secure facilities and monitor workers are as considerable as the risks are, so I expect that this sort of monitoring will become more prevalent.
