This study addresses the challenge of enhancing financial inclusion for the Bottom of the Pyramid (BOP) population through the selection of appropriate mobile payment technologies. Despite the increasing digitization of banking processes, a significant portion of adults in developing countries remains excluded from the formal banking system. This research aims to develop a robust methodology for selecting mobile payment technologies tailored to the unique needs and constraints of the BOP demographic. Building upon existing research, the proposed methodology outlines a systematic process for evaluating and prioritizing mobile payment technologies for BOP communities. The methodology begins with a comprehensive user characterization, followed by technology identification and user base analysis. The prioritization step involves assessing each technology against predefined criteria, including ease of integration, scalability, security, and provider trustworthiness. Cost assessment and usability evaluation further refine the selection process, ensuring affordability and user-friendliness. The study offers valuable insights for stakeholders seeking to promote financial inclusion.
