A woman walks into a government office after completing an online registration process. She is asked to submit printed copies of documents she has already uploaded. Across town, a small business owner files taxes electronically but is later required to present physical copies for verification. A patient registers digitally at a hospital, only to fill out the same information again on paper before seeing a doctor. Meanwhile, millions of Nigerians transfer money, pay bills and run businesses seamlessly from their mobile phones every day.
