How Nanotech Can Foil Counterfeiters

University of Florida researchers Dr. Roozbeh Tabrizian and Dr. Swarup Bhunia, professors in the Department of Electrical and Computer Engineering, have developed tiny mechanical ID tags that are unclonable, cheap, and invisible. Their team has come up with a different solution to thwart counterfeiters based on radio-frequency (RF) nanoelectromechanical systems (NEMS). Like RFID tags, the RF NEMS devices don’t have to be visible to be scanned. That, their tiny size and the nature of their constituents make these tags largely immune to physical tampering or cloning. And they cost just a few pennies each at most. Unseen NEMS tags could become a powerful weapon in the global battle against counterfeit products, even counterfeit bills.
