Heuristic Based User Interface Evaluation of Mobile Money Application: A Case Study

Mobile money is creating entirely new opportunity for mobile devices and provides functionalities similar to e-commerce. The nature of these devices pose two major limitations that are small screen size and lack of input capability, which makes designing applications for mobile devices a challenging task. It is important that the user interface is user-friendly and help users easily obtain their desired results. This study applied heuristic evaluation to examine the interface of SMS based mobile money application provided by vodafone called M-Paisa in Fiji. User interface evaluation of this application based on seven heuristic involving fifteen experts is described. The results show that there are minor usability problems with M-Paisa interfaces and we provide our recommendations to address them. Findings of this research can be applied to develop a set of guidelines to support the future design of effective interfaces for other mobile money applications.
