Document the accessibility barriers that prevent digital-first fintech platforms from reaching low-literacy populations in emerging markets despite ubiquitous mobile phone access.

Cross-country survey of fintech app usability for low-literacy users (IQ test <5), ethnographic research with 500 users across Kenya, India, Nigeria, Philippines, analysis of app design patterns that create exclusion.

85% of fintech apps are completely unusable for low-literacy users. Icon-based interfaces (the most accessible option) reach only 23% adoption. Platforms optimized for low-literacy show 4x higher adoption and retention among target demographic. Current market competition optimizes for early adopters, not accessibility.
