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.

Many of the existing usability evaluation models for mobile applications have not been evaluated to determine its usefulness, accuracy and applicability in to the real world environment. This may not provide confidence on the side of the evaluator and the results may not be comprehensive and valid. A model for evaluating the usability of mobile banking applications interface is developed in response to usability practitioners and mbanking applications developers’ needs. The experts implemented the model using various m-banking application platforms through heuristic evaluation method. A list of predefined validation measures were used by the experts’ in order to determine the accuracy and applicability of the proposed model. The results show that the model is useful, accurate and can be used for evaluating the usability of m-banking applications interface. Therefore, this paper will benefit both the research community and the usability practitioners towards better understanding of m.

Usability has greatly been considered as one of the significant quality attributes to determine the success of mobile application. Mobile banking application is increasingly recognized as an emergent m-commerce application which dignified to become the giant killer mobile application arena. However, prominent usability evaluation models for mobile applications are too general and do not adequately capture the complexities of interacting with m-banking application platform. Similarly, there are no sufficient descriptions concerning the relationship between phases and appropriate usability measures for a specific application. Some banks do not offer m-banking application, while those that offer have inadequate functionalities and this shows that their interfaces are still insufficient and not user friendly. To date, usability and measurements for m-banking application in particular is very limited or even isolated and this makes usability evaluation of m-banking more of challenging. Consequently, this report proposes to address this matter by proposing a suitable and an appropriate set of usability dimensions and measurements for m-banking evaluation. The systematic literature review was employed to review relevant journals and conference proceedings. Seven hundred and eight papers were downloaded but merely forty nine papers have been selected and fully reviewed/analysed. Five usability dimensions and twelve relevant criteria (sub-dimensions) have been created that can be used to evaluate m-banking application.
