The difficult thing that you're going to run into is that most banks (outside of the big guys (Wells Fargo, Citi, BoA, etc) you're going to be utilizing an "off the shelf" system for all of your online banking. There's only a handfull of these vendors out there controlling the market, so little to no incentive for them to innovate and make things easier so requesting new features, updated UI/UX and so on are very slow to be added. In this space "mobile banking" still very much means SMS messages. Now "in front" of the loggin theres many ways you can utilize the web to make things better. Look at how any receptacle consumer service is using the tools available to market and communicate with their customers, general great customer service through email, twitter and so on are all good options but will require some due-diligence brought on by compliance regulations. Good luck and let us know how it goes!
