In my opinion, security is just a typical game of cat and mouse. The rewards are just higher than usual.

RFID devices are not exempt from this perpetual cycle. Their integration into US passports, enhanced drivers’ licenses (EDL’s), EZ Pass, Speedpass, and anything else has been a potential problem since day one. RFID tags do not make it impossible to replicate what they are supposed to be securing, it only makes it a little harder (and more expensive). This can be seen in the recent article at The Register about how Chris Paget was able to build a proof of concept device to catch and clone RFID tags. Even while driving. The potential threat is nothing new in theory, but this is an actual instance of doing it in real life.
