The mobile banking volume has increased significantly to 10X in 2017 from 2011, and it will further increase 3x by 2021. The visit to branches has been dropped significantly, and it will further change as soon the right eKYC solution will be used.
The study shows that 58% of banks are aware of Fintech, and having the intention to derive more on Fintech either to introduce latest technology e.g AI, cognitive computing, bot, blockchain and robotic process automation, or they are acquiring or collaborate with them.

What is happening that these banks are just putting a layer on layer of tools and software to provide better customer experience?
