I am in phase of researching different approaches for designing saving bank account opening from phone/tablet. It will be a combination of responsive and adaptive layouts.
The challenge we have is the length of the form and given the number of fields we have on the form it will likely be very annoying for the customer do it on the mobile. Maybe using at tablet it might work but for mobiles I was thinking of any other better approach.
One interesting though I got in my mind was: we can get customer postal address details from mobile service provider and fill the form or ask them enter SSO number/drivers license number. (Whether this is even possible from a technical perspective is another matter though).
Is there any research / suggestions into this idea from a UX point-of-view?
