Here's more on RFID chipped people relating to my article of last week.

Someone sent me an Internet.com news article that quotes a VeriSign official saying that 2,000 people worldwide have RFID chips implanted. Of those, 68 are in the United States. The majority have been chipped for medical reasons.

That means there must be more than 2,000 worldwide, because the do-it-yourself crowd I talked about use non-VeriSign chips. Popular favorites appear to be Philips HiTags or Avid chips meant for pets (although I doubt either company intends their chips to be used this way -- remember these are bootleg uses).
