That would probably work, as long as you could find the chip. Some chips are really small, but if they are the active kind that can broadcast their
location by themselves, they should be big enough to find. If they are the passive type, I wouldn't even worry about them being there.
I'll have to see if I can find some technical data on typical RFID chips. Hopefully with my engineering knowledge, I can find an easy way to wreck
edit begins here:
Assuming that the datasheets on that website are typical RFID devices, then they are designed to take quite high voltages, since they need to be able
to resist static electricity. Some of the typical values in those datasheets are maximums of 30mA, 7.5V and 200 degrees celsius, and they also say
they can take 2000V of static electricity. Unfortunately, 30mA or more can be dangerous if you don't really know what you are doing. Perhaps the
simplest way would be to destroy the devices with high temperature, like tossing them in the oven for a few hours. (would that wreck the clothes,
though?) That might even work better than the microwave, though that would probably work just as well.
Even though the chips are designed to withstand static electricity, they will still be vulnerable. If you keep shocking them over and over,
eventually you will wreck it. (I've lost a few chips to static electricity before in labs... given the frustration that causes, I can't believe
I'm actually advocating doing this on purpose!
) I'm not sure how long that would take, but I would stick with roasting it under high
temperature; that's easier.
For those who mentioned magnets, I don't think that would work for most RFID chips, but it would depend on what they were made of, mostly.
Does WalMart have RFIDs tagging their stock, yet? I heard that they were considering this, but I haven't heard if they've gone through with it as
of yet. If they have, maybe I can pick a few up and do some "experiments" on them...
