The FDA has approved an RFID chip designed to be implanted in humans. RFID chips are the things used by major store chains to track inventory electronically… sort of a digital barcode. The chip is intended to be used for medical purposes, and I do see some benefits there, but it sounds like they haven’t put a lot of thought or effort into the privacy issues. There’s some interesting commentary on Ars Technica. Apparently, the Bush administration plans to push for RFID-based passports. Somebody save us from our country, and quick!
