No. RFIDs are passive. The only way to destroy one is to physically destroy it.

id rather not expound on this one...you might be another...bad boy

U can nullify it with a microwave.

From RFID Journal (not necessarily a peer-reviewed scientific journal) comes this article: http://www.rfidjournal.com/article/articleview/2098/1/1/ Excerpt : -------------- RFID-Zapper Shoots to Kill Two students turned a disposable camera into a gadget that shocks the life out of RFID tags; now, a privacy advocacy group hopes to sell devices based on their design. ...The young inventors say their motivation was concern over the potential use of RFID tags on individual items purchased by consumers. "We read a lot about RFID and its future use and got worried," says Mahajivana. "Some easy way of getting rid of them had to be found. Frying them in the microwave oven wouldn't be an adequate solution most of the time, as it could damage the already-purchased item the tag was attached to. But causing the chip to burn through somehow seemed to be a good idea." The duo's prototype uses the casing and electronics of a single-use camera with a flash. Within the next few weeks, the duo claims they will post online instructions explaining how others can build a copy of their tag killer for their own use. "Whoever wants to build an RFID-Zapper is welcome to do so, as long as he's not making any profit with it," says Mahajivana. The design replaces the camera's built-in flash with a coil of coated copper wire. The inventors removed the film and, after disconnecting the camera's capacitor from the flash, soldered one end of the coil to the capacitor and the other end to one pole of a switch used to turn the device on or off. They then connected the switch's remaining pole to the capacitor's other terminal. Once the camera is reassembled and held very close to an RFID tag, the duo explains, pressing its shutter button causes the coil to emit an electromagnetic pulse that will overload the tag's circuitry and destroy its ability to function. "For quite some time, I've been thinking about some further use of the concept. A combination of a tag-finder and a tag zapper would be cool, as it would be a design that would allow small mass production." ...Although the RFID-Zapper's design is complete, the duo says they have thus far been able to test their zapper only on 13.56 MHz tags...they would welcome the chance to test their device on tags operating at other frequencies, however, and have asked visitors to the RFID-Zapper Web site to provide the team with such tags. -------------- Unfortunately their inspiration came from an article published in German, not English.
