OK, here's how it works. There's a RFID chip in tha package, and a sensor under the shelf if the store is set up for this system. When you pick up the package (a very small, expensive, high-theft item,) a normal store camera snaps a picture of you. When you get to the checkout, the chip is deactivated, just like the chip in a security tag or a library book. If the tag isn't deactivated and it passes through the exit, another camera takes a picture of you, and a security person walks over and checks your reciept. Either the chip wasn't properly deactivated, in which case the deactivation system is fixed at the register where you checked out, or you have some explaining to do. It's also a good way to check if anyone in the warehouse is helping themselves to some high profit-to-size ratio products that can be resold.
It's not a conspiracy, it's an anti-theft device. The people who are complaining about the health effects of RFID readers are the same people who tell you your TV will melt your eyes and your cell phone can give you brain cancer.
The chips won't be read once you're outside the store, and if you're buying it and not stealing it, you dont' have to worry about the chips while you're in the store. Even if they were read after that, what's the worst thing that will happen? Are Gilette employees going to drive down the street scanning from their van and stuff your mailbox with ad flyers?
