The ID4D project aims to increase the number of persons with national ID numbers through a robust and inclusive foundational ID system. The system supports various development initiatives, including financial inclusion, social welfare programs, and security services. The project has already demonstrated significant progress, with over 64 million Nigerian bank accounts now secured through biometric authentication. The extended project carries total funding of $430 million, a substantial increase from the initial World Bank commitment of $45.5 million. The continuation will enable a more comprehensive implementation of the national ID system, facilitating broader citizen enrollment and NIN issuance. The system features multimodal biometric authentication, including fingerprint and facial recognition capabilities, supporting the country’s recent move toward contactless biometric capture for government services.
