Researchers, Kai Cao and Anil Jain, from the Department of Computer Science and Engineering at Michigan State University have loaded up an inkjet printer with cartridges designed for printing electronic circuits, and used the output to fool smartphone fingerprint sensors on a Samsung Galaxy S6 and a Huawei Honor 7. They just needed a reversed scan of the victim’s fingerprint, and an inkjet printer loaded up with ink and paper from printed electronics specialist AGIC. Read their paper ::HERE::.
