Silicon-based electronic circuits are clearly too thick to be incorporated into thin and fragile banknotes, but semiconducting organic molecules might be a viable alternative.More info at NewScientist.
A team of German and Japanese researchers created arrays of thin-film transistors (TFTs) by carefully depositing gold, aluminium oxide and organic molecules directly onto the notes through a patterned mask, building up the TFTs layer by layer.

Counterfeiting money may become a lot harder in the future as a team of German and Japanese researchers are developing a new technique that makes it possible to stamp simple electronic circuits onto banknotes.
