Wandering the streets of Shanghai to admire the architecture, the head of one of the largest U.S. consumer banks recently found himself surrounded by a gaggle of teenagers.

Entranced by their phones, they hardly made way for the banker. The teens were messaging, shopping and sending money back and forth, all without cash. Instead, they were using Alipay and WeChat.

The scary thing for the American: Banks never got a cut.
