Verayo claims its RFID chips are 'unclonable'

San Jose, Calif.-based startup Verayo says it has developed a new, "unclonable" RFID chip that uses each chip's tiny, unique manufacturing flaws as the basis for security.

RFID tags, which are found in your corporate identification tag and your passport, have been the subject of great debate because they transmit information using radio waves, which can be intercepted.

According to the company, a stray atom could mean the difference between an accepted or rejected authentication attempt.
