So much for the security of RFID tags: development is already underway for the Tag Zapper, a device which purports to be able to “erase” RFID tags and render them blank. The device is “proposed” (which I’m guessing means “still in development”) but an interesting scenario is put forth on their website:
Proposed scenario:
A consumer purchases a six-pack of beer at a convenience store.
After exiting the store the consumer uses her TagZapper™ to disable the RFID tags.
At this point the consumer is able to transport and consume her purchase without being monitored by any commercial or government agency.
Right. Or, you could really piss off Wal-Mart by erasing the tag BEFORE you leave the store. Not that the developers of this device (or myself, for that matter) would advocate such a thing. 🙂
While still vaporware, the product doesn’t seem to be too far-fetched. A competing product, the RFIDWasher, is supposed to be out by the end of the year.
