Accessibility is a big part of getting consumers to use mobile banking, and Fifth Third is among the early adopters of short domain names that are easy to use and easier to remember.

“These names are popular with mobile customers because of their brevity,” says Amy Mischler, a vp at dotMobi, one of the few registries to make one and two character names available, a practice it commenced in January in the hopes of attracting retailers wishing for short yet memorable Web addresses. Fifth Third debuted its mobile banking service in February, with the goal of making it available to its entire 12-state territory by the end of March.
