Startup Promises Hard-To-Duplicate RFID Chips

A difficult to duplicate RFID chip? That's the claim of an RFID startup, which is using MEMs resonators to create a unique signal, or "voiceprint," which can't be cloned and can be used to authenticate the chip, according to this RFID Update story.

"Each voiceprint is unique but falls within a defined band so separate readers do not have to be developed for each chip," the story said. "However, MEMflakes can't be read with RFID readers currently on the market."
