The MetaFilter thread on RFID paints a pretty chilling scenario where the items you buy, because of the permanent and washable RFID tags, can become linked to your credit card at the point of sale and from there, your own clothes are tracking your every move! Sure, there are positive uses, you could walk out of the library freely, shop by just picking up stuff, but still, some pretty ubiquitous product suppliers have just bought a mountain of these RFID chips, and there isn't a shred of legislation to control what they do with them

Is RFID inherently Evil? Not a chip in your body, like EvilCorp Applied Digital Solutions proposes, but in your household products, your clothes, and your car. And it's here now ... sold by Benetton, Prada, British retailer Tesco, Proctor & Gamble, and Wal-Mart? Phillips Semiconductor alone has already sold half a Billion of these chips.
