In india Govt has announced new currency denominations of 500 &2000 notes.According to rumours, which were circulating on WhatsApp even before the demonetisation announcement, the new notes would come with what is variously described as a "micro nano GPS chip", which is supposed to be able to help track individual notes by way of satellite.as per this [1],it seems possible but not at large scale.I think this technology is not feasible [1]http://www.bbc.com/news/technology-22369628



RFID might be useful for anti-counterfeiting or close-range detection, but the maximum reading distance measures in tens of meters at the very best. And it's easily shielded off with a metal case. Tracking bills from space is stuff from bad spy movies.
