ABSTRACT
The Fourth Industrial Revolution created many opportunities in many industrial sectors to cope with the digital transformation emergence. The financial industry quickly developed mobile cashless payment transaction systems (e-wallets) that went viral and have been widely used. Compared with traditional payment services, cashless payments offer other advantages encouraging users to utilize the technology more often. In addition, Covid-19 accelerated the adoption of e-wallets as social distancing, and contactless transactions have been advised in response to limit the transition of the virus between people. Accordingly, this research is aimed to identify the main factors that encourage users to adopt e-wallet systems and the main concerns of the cashless technology before and during Covid-19. This research used the Systematic Literature Review (SLR) approach to answer the research questions that rolled around identifying these factors. The papers were selected between 2018 and 2022 as a representation of before and during Covid-19. The analysis of the chosen literature highlighted 31 total factors, 21 factors about e-wallet usage and 10 factors about technology concerns. Based on the identified factors, this paper can be useful for e-wallet technology practitioners in the field to provide better cashless payment services. © 2023 IEEE.
