Prior studies indicate that a few studies address the potential factors that affect users' intention toward mobile wallet adoption. This study aims to plug this gap by generating an integrated model to determine the critical factors influencing users' decisions toward mobile wallet adoption in Oman, drawing on the various technology acceptance theories. Moreover, the present study model is introduced using Unified Theory of Acceptance and Use of Technology models (UTAUT2). This Research is designed to follow a quantitative approach using an online questionnaire sent to potential mobile user respondents in Oman. Three hundred respondents were collected from mobile wallet users to answer the research question. Partial Least Structure Equation Modeling (PLS-SEM) was used to assess the significant factors affecting the adoption of mobile wallets in Oman. A total of thirteen factors have been identified which affect m-wallets adoption intention in Oman. In addition, user's attitude has been made to make the most impact and be a key driver in influencing users' adoption of mobile wallets technologies. Moreover, according to the order of their significant effect, perceived reputation, hedonic motivation, perceived trust, performance expectancy, personal innovativeness, and social influence were also significantly associated with participants' intentions toward m-wallets. However, effort expectancy, anxiety, perceived privacy, perceived risk, and grievance redressal have no affiliation with individuals' intentions toward m-wallets adoption. Practically, this study will be helpful for the merchandise stakeholders of mobile wallets who want to broaden the area of their business to gain more market shares.
