User Interaction Design for Financial Technology Mobile Application using User-Centered Design

The development of information technology that transforms traditional technological processes into modern ones is called digital transformation. Various industries in the world, including Indonesia, have been disrupted by digital transformation. One industry that has been disrupted by digital transformation is the application of information technology in financial services, namely financial technology in the digital payment section. The ease and convenience provided by financial technology needs to be followed by responsible use, financial technology services need to facilitate their users to have a healthy financial behavior. After conducting user research using questionnaire, users feel that the ease that comes with the application can result in consumerism. In this paper, we present the result of our observation in designing the user interactions of a financial technology mobile application added with a new feature called budget control. The user-centered design approach is used to design the high-fidelity prototype of the application based on the users' needs. The prototype is designed based on usability goals and user-experience goals defined for the users. We conduct a usability testing to evaluate the prototype using system usability scale questionnaire, single easy question questionnaire, and user interviews. The results show that the prototype fulfills the usability and user-experience goals.
