Arphid Watch: the RFID Guardian jamming device

http://www.personaltechpipeline.com/190900540?cid=rssfeed_pl_ptphttp://www.engadget.com/2006/07/22/researchers-developing-anti-rfid-device/The RFID Guardian is powered by a 550MHz XScale processor (as found in many PDAs) with 64MB of RAM and runs on the eCos open source OS. The mechanics are pretty complex, but the short of it is the Guardian uses "standard authentication algorithms from cryptography" to recognize RFID readers and to accomplish its two primary objectives: tag spoofing and tag jamming, both of which prevent your RFID tagged object from being identified. (((To judge by the naked circuit boards and ribbon-cable in this tabletop proof-of-concept model, some blobject designer shell-casing is in order.)))
