The single biggest problem with RFID technology is it is exceedingly susceptible to static electricity. Plans are to put these things in just about anything. Problem is static electricity inherent in production processes kill 'em before they get planted. The sure fire way of destroying the buggers is to zap 'em with ESD or electro-static discharge. Draw a static arc and they will die. I can see a business plan coming together to produce and distribute a consumer device designed to zap chips. I can also see fed.gov writing laws to hinder attempts to establish privacy.
