With technological developments and the digitalization of business processes in the banking sector, physical and virtual environments are complementing each other. Electronic channels are no longer considered as additional or less costly way of interacting with customers. Today, they represent a considerable and constantly growing part of the activities of bank institutions worldwide. The aim of this work is to assess the impact of trust in the development of fintech banking through a transnational analysis. The results of this work can be used to map the countries that studied this topic. The findings of this study reveal that, despite the fact that research in this field has been carried out in a wide variety of economic and cultural contexts (45 countries were surveyed), the previous studies agreed on the strong presence of trust as an entry barrier for the development of financial technology in the banking sector. In addition to trust, other adoption factors appear to be essential for consumers. The vulnerability resulting from digitalization in the banking sector has enabled us to formulate some suggestions for further investigations.
