The second covers a "hacking the system" concept. I'd considered something similar myself, though different in approach. Rather than finding RFID chips and "redistributing" them, why not create programmable RFID broadcasters which could spoof other chips, and distribute these. The idea being to pollute any RFID detectors with a vast spew of superfluous data.
RFID jamming should be very easy and a quite amusing DoS attack on commercial targets. Easy because its not frequency hopping, low power, and relatively low frequency. Particularly cute would be transmitting sex-toy codes intermittently.
ASK any Elmer you happen to see, what's the best jamming, RFID..
(With apologies to the tuna industry and those too young to know the jingle. Or to know the RF double meanings.)
I remember the tune (grin). Ah, childhood. Would RFID jamming really be effective? RFID scanners work when the chip passes the scanner - when a pallet passes a door for instance - at which point the scanner 'knows' that chips Abe, Bill, Charlie passed point Delta. To get the jammer to work it would have to be run past the scanner - I don't see how an RFID jammer planted in (say) the changing room at Wal-Mart would be an effective DoS? It's possible I'm ill-informed or just unclear on the concept. ~brian
