Gregg speaks with Matan Parnes, PayPal's Head of Global Risk and Data Sciences, about the ways that money is being revolutionized - and put at risk - in the digital age. Topics include: how PayPal is developing "story based" technology to detect good people from bad; China's headstart in adopting a zero-cash economy; and a new generation of digital criminals, tasked with reaching same kind of quarterly revenue targets as the law-abiding people and companies they're trying to defraud.
