This next generation of fingerprinting could offer a more effective way to authenticate products or create bank notes that cannot be counterfeited. The ‘nano-fingerprints’ are a sprinkling of silver nano-wires stuck on to a thin plastic film. “They are millionths of a metre thick and 20 to 30 of them are scattered on to the film randomly to produce a unique pattern,” notes project lead Professor Hyotcherl Ihee of KAIST. The research team’s work has been recently published. According to the research, tagging for an electronic device could cost as little as 72 Euro cents.
