Tiny Transistors Track Cash

These itty-bitty low power organic transistors can be placed on the surface of bank notes for security or tracking by transmitting information wirelessly to a scanner. A group of German and Japanese scientists manufacture these 250-nanometer-thick transistors using minute amounts of aluminum and gold and a special dry process. They work well on the rough surface of paper and need only three volts to operate.

Pretty soon it will be transistor tattoos or skin implants that track us and keep us "always on". Foursquare will be right on it - human adbots live updateable without smartphones (phones and RFID will be so early 21st century).

Because we all know great things happen when Germany and Japan get together, right?

But really, they will just get damaged too quickly. I don't how much redundancy is built in but if you loose just one or two it may stop working.

Also what about recycling. I know it is an incredibly small volume but it all adds up. Gold is an incredibly important resource. If only we could rapper to stop putting it in their mouths.
