The use of banking automated teller machine (ATM) technological innovations have significant importance and benefits in Nigeria, but numerous investigations have shown that illiterate and semiliterate Nigerians do not perceive them as useful or easy-to-use. Developing easy-to-use banking ATM system interfaces is essential to accommodate over 40% illiterate and semiliterate Nigerians, who are potential users of banking ATM systems. The purpose of this study was to identify strategies software developers of banking ATM systems in Nigeria use to create easy-to-use banking ATM system interfaces for a variety of people with varying abilities and literacy levels. The technology acceptance model was adopted as the conceptual framework. The study's population consisted of qualified and experienced developers of banking ATM system interfaces chosen from 1 organization in Enugu, Nigeria. The data collection process included semistructured, in-depth face-to-face interviews with 9 banking ATM system interface developers and the analysis of 11 documents: 5 from participant case organizations and 6 from nonparticipant case organizations. Member checking was used to increase the validity of the findings from the participants. Through methodological triangulation, 4 major themes emerged from the study: importance of user-centered design strategies, importance of user feedback as essential interface design, value of pictorial images and voice prompts, and importance of well-defined interface development process. The findings in this study may be beneficial for the future development of strategies to create easy-to-use ATM system interfaces for a variety of people with varying abilities and literacy levels and for other information technology systems that are user interface technology dependent.
