Cashless banking has gained popularity over the years, with the increasing adoption of digital payment methods, such as mobile payments, internet banking, and electronic fund transfers. This trend has significant implications for the banking industry, particularly deposit money banks, which rely on deposits as a primary source of funding. The purpose of this study is to examine the relationship between cashless banking and the performance of deposit banks. The study employs a quantitative research method. The quantitative component involves the use of secondary data from financial statements of deposit banks for a period of five years (2016-2020). The financial performance indicators to be analyzed include return on assets (ROA), return on equity (ROE), net interest margin (NIM), and cost-to-income ratio (CIR). The data collected from the quantitative components was analyzed using thematic statistical techniques. The findings will provide insights into the impact of cashless banking on the performance of deposit banks and the factors that influence this relationship. The study's results will be useful to deposit banks, policymakers, and other stakeholders in the banking sector as they make decisions on the adoption and implementation of cashless banking.
