San Francisco-based Wells Fargo (NYSE:WFC) is the shining star of conventional banking. But with its recent debut of a small neighborhood-concept branch in downtown Washington, D.C., the bank may have new ideas for how banking should be done.

The branch has moving walls that open during business hours to accommodate complex customer needs, while the remaining space is dedicated to three large full-service ATMs -- or more apporpriately termed "store transaction machines" -- that can handle a variety of banking transactions that a traditional teller line would normally handle.

In the video below, Motley Fool contributor Jessica Alling discusses the new concept,  if it's a sustainable source of banking service, and how it would help Wells Fargo and its investors.
