Some info on Faraday pouches. On eBay, there are a lot of the silver mylar bags being advertised as protection from an electromagnetic pulse. They don't work as Faraday pouches for our car keys (and probably not for an electromagnetic pulse, either--they are for static electricity). I put my key in one of these silver pouches and it still unlocked the door. The ones that work, for me, are the gold-colored "fabric", usually encased in some sort of durable covering with a velcro flap to close off the opening. The fabric may wear with repeated use at some time in the future, but not yet. I also carry my passport in one of these to shield the embedded RFID chip that all passports now contain.
