Mobile banking is becoming increasingly important as smartphones and tablets proliferate. By 2015, over 1 billion smartphones and 400 million tablets will be in use worldwide. Mobile internet usage will surpass desktop usage by that time as well. 400 million people are expected to use mobile banking in 2013. However, many banks have been slow to adopt mobile solutions. To remain competitive in the emerging mobile landscape, banks will need to quickly develop new mobile architectures and services to meet rising customer demands and address security concerns, while also navigating new players in areas like payments and lending.
