Banknotes Go Electronic To Outwit Counterfeiters
suraj.sun writes "Modern banknotes contain up to 50 anti-counterfeiting features, but adding electronic circuits programmed to confirm the note's authenticity is perhaps the ultimate deterrent, and would also help to simplify banknote tracking. From the article: 'A team of German and Japanese researchers created arrays of thin-film transistors (TFTs) by carefully depositing gold, aluminum oxide and organic molecules directly onto the notes through a patterned mask, building up the TFTs layer by layer. The result is an undamaged banknote containing around 100 organic TFTs, each of which is less than 250 nanometres thick and can be operated with voltages of just 3V. Such small voltages could be transmitted wirelessly by an external reader, such as the kind that communicates with the RFID tags found on many products.'"
Why do we still carry money anyway?
It's hard for me to imagine any security measure economical enough to implement in $20 bills could not be replicated by a really well-funded forger, such as a foreign intelligence agency. If there is any "ultimate" deterrent, it would involve tracking the movement of funds from one individual to another, i.e. marginalizing the use of cash, or making it equivalent to electronic banking, so Big Brother can keep an eye on it.
All that money won't be worth the paper it's printed on in a few years anyway.

Poorer countries such as Nicaragua, Nigeria, Bangladesh and Kuwait use them, so why have other countries not caught up?
This isn't just the US, but the EU and UK as well. Why stick to paper when much more advanced tech has been around for over 20 years and is being used by third world countries?
If you ignore ACs because they are anonymous - you're an idiot.
