This book examines Ghana’s use of the fingerprint biometric technology in order to further conversations about localization championed by technical communication scholars. Localization, in this case, refers to the extent to which users demonstrate their knowledge of use by subverting and reconfiguring the purpose of technology to solve local problems. Dorpenyo argues that the success of a technology depends on how it meets the users’ needs and the creative efforts users put into use situations. In , Dorpenyo advocates studying how users of technological systems construct knowledge about the technology and develop local strategies to solve technological breakdowns. By analyzing technical documents and interview transcripts, the author identifies and advances three user localization strategies: , , and , and considers how biometric systems can become a tool of marginalization.
