The development of financial technology in areas such as mobile internet, cloud computing, big data, and blockchain technology has significantly changed the financial industry. FinTech is expected to partially disrupt the traditional banking business model, forcing banks to transform. The subject of the research is innovations in the mobile payment ecosystem. The aim of this paper is to provide a detailed insight into the technologies that have been implemented in mobile payment methods and to describe the factors influencing their increasing use. As part of the paper, research was conducted which, using a survey questionnaire, included a sample of 112 people, aged between 18 and 35 years. The aim of the research is to assess the acceptance of mobile payment methods among the young population of the Republic of Croatia. The results were processed by the methods of analysis and description, which show that a large percentage of respondents still do not use digital wallet services. Respondents are most confident in paying by credit and debit cards, which they use both in physical stores and online. When it comes to mobile payment, the most important factors for them are safety, convenience, and speed of transaction execution, while they do not care about not having to carry their wallets.
