I was think of this the past few weeks , OMG I can not believe that there is someone actually working on this , That is just amazing . The idea is so close to what was in my mind but I am not sure if it is similar . What was in my mind is to make this Banknote process a  decentralized process so anyone in the world can just scan his BTC and use it , There was a lot of details in my mind , But ya this project is something close to what in my mind , Wish you luck guys .
