>>Metal mosquito net works just as fine for most purposes. We've seen a guy holding his ID in a metal box... and he was a cop, in uniform. Does he know something we don't? As our ID has a chip in it, not quite sure whether it's RFID or on close contact only - the readers are usually bundled with a printer, so the printout serves as a proof of identity. Which doesn't mean there can't be other, much smaller machines, capable of reading it. Since there are no metal contacts exposed, I guess it's some kind of RFID, allegedy with very short range, yeah right. And it's actually optional - I checked the other checkbox on the form and mine is electronics-free plastic.

>There are discusions how far a RFID (aka secondary RADAR) reader can work.This is a bit more tricky then just reading, because you need to transfer the energy to the tag first. It requires a lot of energy to be transmitted by microwaves. A far distance reader might be a bit of a microwave oven on close range. There was something about the energy and the distance and the square root. It will be not better if the tag is not perefectly aligned.
>Put it in a metal wraping should help anyway. Soft iron is better. But watch out. You will be handled as a terrorist by hiding ID. :)

Now then it might be a good time to become a muslim. Grow a beard and wrap the women - much more work for facial recog algos...
