An anonymous reader writes to tell us that a new RFID chip from Verayo claims to be unclonable through the use of the new Physical Unclonable Functions (PUF), sort of an electronic DNA for silicon chips. "Basic passive RFID chips can be easily cloned by copying the data residing on one chip to another. Verayo's PUF-based RFID chips cannot be cloned, and provide a very strong and robust authentication mechanism. No other chip or device can be disguised as the original chip, even if the data is copied from one Verayo RFID chip to another."
