The only women who could live legally in the townships were the wives and unmarried daughters of the African men who were eligible for permanent residence.
In the same year, the Natives Abolition of Passes and Coordination of Documents Act was passed. In terms of this act the many different documents African men had been required to carry were replaced by a single one - the reference book - which gave details of the holder's identity, employment, place of legal residence, payment of taxes, and, if applicable, permission to be in the urban areas. The act further stipulated that African women, at an unspecified date shortly, would for the first time be required to carry reference books.
