Computerworld has an opinion article by Jay Cline about the privacy scare surrounding RFID technology who explains that the RFID hype has outpaced reality. Manufacturers and retailers have yet to agree on a universal electronic product code. RFID scanning is also far from error-free. But more important, RFID signals are so weak that they're easily blocked by metals and dense liquids. It's infeasible today for someone driving a vehicle down your street to intercept signals from RFID-tagged goods inside your home.

He also argues that the economics of RFID chips also limit how they're used. Until the price of RFID chips comes down to about a penny apiece, they'll mostly be used at the case and pallet level, clear of any personally identifiable activity. So we have several years to identify the privacy controls we want to see in RFID systems. Some companies are already creating these privacy controls. Chip makers and users are discussing how the principles of data privacy could be built into the RFID process. A top priority is notifying customers that certain items are tagged with these transmitters - which could be done by placing a common RFID logo on product packages. To give customers the ability to turn off the transmitters, some companies plan to make them peel-offs. RSA Security Inc. is also developing a chip that could be worn on watches or bags to block nearby RFIDs from transmitting certain information. So the RFID privacy ball is rolling.

Glad to hear that. Nevertheless, I will still be watching the RFID development with interest...
