Ndaga Muntu, Uganda’s national digital ID system, is a government showpiece that is of major importance for how individuals access their social rights and for how the Ugandan government operates. Initially designed to serve national security objectives that have dominated its operation ever since, Ndaga Muntu has never made good on its other promise to foster social inclusion, a promise often repeated by proponents of digital ID systems around the world. Four as our seven months of in-depth research investigating the impact of this national ID system on the human rights to health and social security for women and older persons will show that Ndaga Muntu has led to mass exclusion, shutting out as many as one third of Uganda’s adult population, and has become a barrier for women and older persons, as well as many other marginalized individuals, to access their human rights.
