RFID Tags: Big Advantage or Big Brother?
C|Net has posted a comprehensive article on the issue, discussing the pros and cons of personal RFID tagging. The primary argument against tagging is potential invasion of privacy and identity theft. Others point out that the technology could become obsolete so quickly as to make tags useless within a few years. Objections on religious grounds ("the mark of the beast") are also anticipated.
RFID tagging is an intriguing and potentially disruptive technology that offers as many benefits as it does risks. But it's still in its early stages, and it's too early to talk seriously about widespread tagging initiatives (we're still arguing about the merits of tagging packages, so how can we even begin to tackle humans??). RFID is a rapidly advancing technology, so emerging technologists will be watching developments in the field very carefully.
