Cincinnati-based Fifth Third Bank has revealed the addition of Touch ID biometric capabilities to its mobile banking app for the iPhone.Touch ID allows fingerprint authentication for enabled devices, letting customers log into their Fifth Third app with their fingers or thumbs instead of a password.”Our customers' digital expectations continue to evolve – and many of those expectations are being set by using non-bank apps such as shopping and games,” said Chad Borton, executive vice president and head of the Consumer Bank for Fifth Third Bank. “Fifth Third is continuing to evolve its digital experiences to do the same, creating fast and simple banking.”Mobile banking is outpacing online banking for Fifth Third customers, with mobile banking increasing 43 percent from 2014 to 2015, with 19 million mobile banking logins last year. Meanwhile, Fifth Third consumers increasingly want the services mobile banking can provide, such as alerts, which increased 144 percent from 2014 to 2015, with 13.9 million alerts sent last year.
