Members of the RFID Guardian Project believe that the potential for mischief is mounting as retailers demand that vendors add RFID tags to everything from TVs to sweaters.

They envision the tags being used for people-tracking, where strategically-placed RFID readers could report the trajectory of your skivvies as they escort the rest of you across town.

It’s not hard to imagine GoogleMicrosoftYahooAOL tying MySpace-You with Walgreens-You with Verizon-You with BananaRepublic-You with VictoriasSecret-You with WellsFargo-You with Target-You with Netflick-You to know more about you than you want to know about yourself… And that’s the Good News.

RFID Guardians can see a terrorist arming landmines to blow up when a victim prances by wearing, say, a WalMart cableknit sweater. They might even selectively blow people up according to the WalMart cableknit’s color.

“OK,” you’re thinking, “More good news.”

But what if the terrorist doesn’t blow you up by color, fabric or vendor? After all, it’s easier to simply blow anybody with an RFID tag up.

Now you can see how serious this is.

Not to worry. The RFID Guardians have built a portable device that inventories all the RFID chips and scanners within range, jams outside chatter with RFID chips you’re bearing, and even fakes RFIDs. Betcha already guessed what they call it: RFID Guardian.

Don’t laugh at the larger-than-personal prototype. It’ll shrink.

Until then, if you’ve embedded RFID tracking chips in your Portuguese Water Dog or forgetful grandmother… you may want to wrap your favorite embedee in tin foil.

I refuse to be held responsible for exploding loved ones… or things.
