RFID Will Stop Terrorists?

W33dz writes "Retailers and manufacturers around the world are enamored with the new radio frequency identification, or RFID, devices. The problem? What about when a thief or the police want to find out what you have in your house? Oddly enough, according to a Wired magazine article, the United States' largest food companies and retailers will try to win Dept of Homeland Security approval for radio identification devices by portraying the technology as an essential tool for keeping the nation's food supply safe from terrorists. This will give them blanket immunity from all law suits related to the product."

Oh how wrong you are

RFID tags cannot be reporgrammed. and they do send out signals (on request from scanner).

RFID tags have a very small amount of READ ONLY memory on board, which is used to store their unique ID. Furthermore, the devices to not have the functionality to write to the memory, even if it was writable. So you can be sure no one will ever buy a RFID reporgrammer on Ebay, well... maybe they will, but you can be sure it's a hoax and they got ripped off.

Secondly, they DO send out the signal. barcodes need a clear direct line of site to a scanner to be recognized. RFID tags work in a much different manner. A scanner could be put in every light post in a city to monitor the RFID tags planted in tires, and track individual cars (or general traffic patterns). Worse, due to the nature of the technology a directional antanne could be used to read an RFID tag from large distances.

In conclusion, your comment is crap.
