The Headline reads differently...
There is another link on the page, but I didnt bother to put it in cuz Im lazy...
Now, the problem is that now just about everyone can know how much cash you carry on you. Take off the Tin Foil Hats for a second and think about how this would be applied in the really real world. A thief, like a pickpocket walks around with a scanner and finds the person that has the most cash on them. They target that person, and well, that person gets really shafted, possibly injured or worse by the thief. If people walked around with signs on their chests telling everyone how much cash they have on them, the thief would ignore the guy that has $8 bucks in their wallet, and go after the guy that has $600 bucks.

"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.'"
