The eavesdropping attack could be defeated by shielding the reader. Make a shielded container, place the reader in it, then slide the passport through a slot to be read. Solved.<p>The same could (and should) be done for any short range RFID transactions. Do them within a cage, and eavesdroppers are thwarted.<p>I&#x27;m not sure, but I think the eavesdropping equipment can also be blocked with RF noise. Just make the vicinity of the reader very noisy, with accuracy limited to a few centimeters, and they will receive a ton of garbage.<p>While we&#x27;re at it, let&#x27;s detect live receivers and require them to be turned off. Cellphones, laptops, pacemakers, everything off within 4meters of the receiver. Well, maybe not the pacemaker.
