RFID Tag Zapper

Destroying RFID Tags Made Easy

A lot has been written about RFID tags and their privacy implications. Looks like the plan is for everything to eventually have an RFID tag, from USA Passports (soon) to just about every consumer good known to man (soon also).

22C3 Private Investigations has come up with a RFID Zapper, which permanently disables RFID tags. Clearly a useful item for law abiding citizens with privacy concerns as well as criminals such as shop lifters.

They modify a disposable camera to produce the prototype RFID Zapper. Development is continuing but they seem to be temporarily out of RFID tags. Plans are to publish documentation that allows anyone to build their own RFID zapper.

Cool, but I'd like to build one inside of a functioning ballpoint pen! Batteries size seems to be the main concern.

Thanks to Bruce Schneier for this.
