Radio tags spark privacy worries

I recently wrote a parody post where I took some text from a livestock tracking supply company and changed it to talk about people instead of catlle. It was written in response to a BBC article on RFID tagging at airports.

Unveiling the study, EU commissioner Viviane Reding said citizens needed re-assuring that radio tags would not lead to large-scale surveillance.

My concern here is really not so much large scale surveillance, although to some extent I worry about it. My true concern is from the identity/privacy standpoint, and the possibilty of remote undetected reading of the data on the tag.

Posts of note, who in general have expressed thoughts I agree with/find interesting/thought provoking:

Reading RFID Cards at Yards Away (and previous articles at bottom of entry)
DEFCON RFID World record attempt... (69 feet)
