Book excerpt: An integrated national identification (ID) system offers a means to fast-track the development process by providing the most efficient way to identify people in developing countries. This report seeks to help governments assess the maturity of a country's ID system and integrate it with development activities. A maturity model for a country's ID management is developed and applied to seven countries in Asia to assess the maturity of their ID systems. This report also provides a way forward for multilateral institutions---including ADB---to make the best use of ID systems in their operations.
