Scientists Find RFID 'Fingerprint' That Could Prevent Counterfeiting
According to Physorg.com, Professors Dale R. Thompson and Jai Di discovered that each RFID tag has a "fingerprint." Essentially, each tag has a unique power response at different radio frequencies -- even for tags of the same make and model. With preexisting physical characteristics in mind, scientists can interpret an electronic "fingerprint" to each tag. Using those fingerprints as a key would make the devices harder to hack and counterfeit.
With RFID being used more and more by government agencies and private businesses, it's comforting to know that somebody is thinking about security. Maybe now we can stop wrapping our credit cards in aluminum foil. It's a good thing this news broke before we let paranoia take over. [From: Physorg.com, via Engadget]
