The use of banking automated teller machine (ATM) technological innovations have significant importance and benefits in Nigeria, but illiterate and semiliterate Nigerians, representing about 40.33%, do not perceive them as useful or easy-to-use. The purpose of this case study was to identify strategies used by software developers of banking ATM systems in Nigeria to create easy-to-use banking ATM system interfaces in Nigeria. The technology acceptance model was adopted as the conceptual framework. One organization in Enugu, Nigeria was used for this study’s population. Data were collected through semi-structured, in-depth face-to-face interviews with nine banking ATM system interface developers and the analysis of 11 documents. Findings from the participants were validated through member checking and organizational documents. Through methodological triangulation one major theme emerged: importance of user-centered design strategies, that encompass five important components: (a) user-centered design processes, (b) importance and understanding of the cultural backgrounds and literacy levels of users, (c) design based on knowledge and understanding of users’ needs, (d) importance of understanding the target users, and (f) simple, user friendly, and easy to use design. The findings in this study provide direction for the future development of strategies to create easy-to-use ATM system interfaces for people with varying abilities and literacy levels and other information technology systems that are user interface technology dependent.
