A Silicon Valley company with a noteworthy founder has created a mobile payment system called FaceCash that it hopes will one day displace credit cards.

You might be tempted to write this off as too audacious. But consider this: The founder is Aaron Greenspan, the Harvard graduate who claimed in 2007 that his former schoolmate, Mark Zuckerberg, ripped off his work when Zuckerberg created Facebook. Greenspan settled a trademark lawsuit with Facebook and Zuckerberg filed in 2008 last year.
