Google pulls plug on plan for mobile banking in Pay appGoogle has ended work on its Plex project, but continues to eye ways to integrate financial services, it said. SAN FRANCISCO: Google has hit the brakes on a project to add mobile banking to its Pay app, even as the online financial services market for everyday investors heats up. "We strongly believe that this is the best way for Google to help consumers gain better access to financial services." Google said late last year that it was working with nearly a dozen credit unions and banks, including Citigroup, for inclusion in its Plex project for its Pay mobile app available on Android smartphones. The Pay app allows users to pay for transactions, send money to friends, and store loyalty cards, among other advantages.
