Words fail me and this is symptomatic of a failing industry.
I too have been through this process a couple of times simply when trying out new digital offerings from supposedly new and forward-thinking institutions.
On one occasion I gave up the process because they specified a certain file size when uploading my evidence of identity, and on the other I still had to go visit a branch.
On the plus side, there are one or two remarkable examples of new banking services which really know how to treat new customers - Revolut and Monese being cases in point. Monzo and Atom are looking good too.
Get a grip, banks.
When financial institutions were asked how consumers could open new checking accounts, less than half could open accounts online, while only 15% of organizations could open accounts with a mobile device. The largest organizations were more likely to be able to support online and mobile account opening, with the credit union segment also performing better with online account opening. The community bank segment is significantly lagging in the ability to support mobile account opening.
