Every year since 2012, payments industry and fintech professionals have assembled in Las Vegas at Money2020, a trade show and conference that its organizers now bill as "the world's biggest, boldest and best event covering payments and financial services innovation for connected commerce at the intersection of mobile, retail, marketing services, data and technology." And almost every year since, UC Irvine has hosted a Payments Afterparty, where a group of academic and industry researchers, colleagues and friends gather to debrief on what we learned or we wish we had learned, what was prominently on display and what should have been but was not.
