At least, that’s what’s bound to happen once the researchers at the Max Planck Institute of Solid State Research’s organic electronics research group get their way. German and Japanese researchers have developed organic, thin film transistors that’s only 250nm (that’s nanometers) thin made with minute amounts of aluminum and gold using a special dry process. “Up to this day, no country has a bank note that contains active electronic features,” said Hagen Klauk, head of the Max Planck Institute of Solid State Research’s organic electronics research group. “We’ve taken the very first baby step, and that is to demonstrate that it is possible in principle to put organic transistors on the surface of a bank note.” If implemented, the transistors can increase the security that’s already embedded into banknotes, and will allow people to literally to follow the money.
