Nevermind that banknotes are less than a millimeter thick, they're soon going to be stamped with electronic circuits for yet another anti-counterfeit measure. The notes will be traceable thanks to the semiconducting organic molecules, potentially putting a stop to bank-heists.
The research was undertaken by German and Japanese scientists, who used gold, aluminum oxide and the organic molecules to create transistors on the notes. Each TFT measures under 250 nanometers thick, and requires 3V of wireless electricity to be read.
