Economy of Repetition has for long been a huge lever when it comes to speed up adoption of new services. A familiar and often used tool is what customers and citizens at large have the right to expect.

Now this is getting exponentially more important as a rapidly growing number of people are moving into the all-digital, e-tool deluge and app-for-everything world. There is less time for any one thing. Starting from tools trusted, must-be-secure,
always-with-you mobile and often used is the obvious choice - and here banks have to take their responsibility (also providing the service to unbanked - as long as they can identify themselves. The business case - albeit not huge - is there. And the public
sector should encourage the development towards a tool that can be used everywhere.
No-brainer really - if you want to speed up adoption, increase security and save costs.
