You know, I would totally buy a tool that would show me information about all the RFID tokens in my “area of influence”, and allow me to block (or, perhaps more interestingly, spoof) selected ones. It would cater to both my urge to hack things, and my tinfoil hat paranoia.
You know, if more and more stores move to using RFID readers as anti-shoplifting systems, this would be a thief’s best friend. I guess it wouldn’t surprise me to see such a thing being outlawed once it was “on the street”.
I should totally go back to university so I could play with these things and call it research.
Still, if it’s in the academic labs now, that means it will be on the street in the forseeable future.
