There will come a point in this erosion of privacy where WAR will be declared.
I for one will be happy to help design and publish information on the building of kit for the location and destruction of RFID tags and readers.
I suggest the destruction of all the readers in supermarkets, etc. that use these devices. An organised raid would quickly leave huge amounts of goods leaving unobserved by the store computer, with the "thieves" largely completely unaware of their "crime" until maybe days later, when their credit cards are not debited.
I have this to say to checkout operators. "CLAIMING JOBSEEKERS ALLOWANCE" Maybe a little, dare I say, sabotage?
