To register families, for example, an existing tool was expanded and improved to produce the Single Registry for Social Programmes; today this registry is used for a series of policies to benefit low-income groups. The federal government transfers income directly to the beneficiaries using magnetic cards that are issued by a federal public bank with a very large distribution network - over 5 570 municipalities. Women hold 97% of these cards because research has shown that mothers know better than anyone how to use funds for the benefit of the entire family, and especially the children. Finally, to provide services and monitor these families, three systems were mobilised: the education system, which monitors the frequency of school attendance by children and young people in the programme; the health care system, which monitors inoculations and the children’s nutrition as well as prenatal care for expectant mothers; and the social assistance system, which focuses on low-income and highly vulnerable families.
