Here's my story, which illustrates one problem with RFID tags:
I purchased a generic wallet at walmart in Nov '03. I immediately began using the wallet, of course (I generally don't buy one until the old one has holes in it...), so I always have this thing in my pocket...especially when I go into the local Winn Dixie grocery store.
For 4 months, every time I went into this particular grocery store (actually I tried other Winn Dixie stores also, and even Rite Aid had this same problem), the inventory alarm went off...now this is when I entered the store. After shopping & paying for my groceries, the alarm would AGAIN sound when I left the store. I had no idea what was causing this... I had recently purchased a new cell phone w/ bluetooth...I thought maybe that was the problem, also had a new Ford truck w/ remote locks...but leaving that in the Truck didn't help, either. Needless to say, I was stopped by security more than once...and got many funny looks from other customers who exited at the same time I did.
Then, one day while bored in a drive through line at the bank, I decided to clean out my wallet & found tucked in a never used fold of leather... an RFID tag! This was one of the large "square spiral" type. I dropped it in the seat of my truck & went straight to Winn Dixie (after finishing the bank business, of course) and...no alarm. Hasn't gone off since then, either.
As walmart uses them more, I'm planning to point this out to everyone who sets off the alarm at the grocery store!
