I searched for this thread after reading the divisive Account Details on the Debit Cards discussion and thought that the way the account number and sort code are displayed in the Current Account app is not very clear (light grey text on white background)
But great to see 
Monzo already thinking about accessibility in general. One great feature for blind users is an accessible debit card. RBS currently provide these and they have a elliptical cut-out on the end of the card and Braille raised dots on the surface. The example below is from Holt’s Bank, but Royal Bank Of Scotland and NatWest also issue these
Do you think this would be something Monzo considers in the future?
