ABSTRACT This paper examines how mobile communication and mobile banking is used by women in rural western Kenya (Elgeyo Marakwet), a resource-constrained area where women must carefully monitor the flow of money through their households. Also, women face structural inequality. Among other things, polygyny (one husband and several wives) is legal. Based on the inductive analysis of 25 interviews with women, and using the lens of intersectionality, we examine their use of mobile banking.
