>> No, anti-static bags don't block RFID

Chris pointed me to a post by his friend Alec about RFID-blocking wallets to prevent remote snooping on proximity cards. Alec asks whether anti-static bags would do the same thing, so in the spirit of the empirical method I gave it a try. Result: no signal attenuation at all. The photo shows a home-made RFID reader getting a successful read off the tag in my arm through 4 layers of anti-static bag.
