Two decades of mobile payment research: A systematic review using the TCCM approach

Researchers have increasingly explored various aspects of mobile payment in the past two decades, including different mobile payment systems (MPS), stakeholders, and related research contexts. However, existing literature reviews are limited to user adoption, overlooking the importance of understanding other key stakeholders, such as retailers and MPS providers, and post-adoption behaviors. To address this gap, this comprehensive review examines exhaustive 310 studies in the MPS literature using the theory-context-characteristics-methods framework, providing insights into all stakeholders and contexts studied. The findings highlight the need for further research in areas such as peer-to-peer payment, MPS adoption in lower-income countries, MPS discontinuance behavior, socioeconomic impact, and consumer privacy issues. Additionally, the study suggests expanding the scope of MPS research to include emerging mobile payment options like buy now pay later and facial recognition payment system (FRPS). This research contributes valuable insights and proposes future research directions for MPS studies.
