Butterfly Inspires Banknote Authentication Tech
VANCOUVER, British Columbia, Canada, Oct. 4, 2011 — Inspired by the wings of the morpho butterfly, Nanotech Security Corp. (NTS), in collaboration with Simon Fraser University, has created the world’s first anti-counterfeiting master die.
The new master die, also known as master shim, can be used to reproduce nanoholes in a variety of materials — including banknotes — in large volumes, quickly and cost-effectively, without changing the manufacturing process.
