This study examined the effects of the fintech of bank performance (i.e., Automated Teller machine
(ATM) services, internet banking (IB) services, Point of Sales (POS) services, mobile banking
(MB) services and interest rates) in Nigeria. Specifically, the study evaluated how bank
performance has been influenced by Automated Teller machine (ATM) services, internet banking
(IB) services, Point of Sales (POS) services, mobile banking (MB) services and interest rate. The
study was hinged on the Diffusion of Innovation Theory (DIT). The study estimation was based on
the autoregressive distributed lag (ARDL) model. The result of the study showed that, from
2009Q1 to 2022Q4, ATM, internet banking and mobile banking services negatively impacted bank
performance in Nigeria, while Point of Sales services positively impacted bank performance. This
study recommends Nigerian banks invest in advanced security technologies, robust cybersecurity
measures, and improved customer support services to mitigate ATM fraud risks, maintain the
benefits of Point of Sales (POS) integration, and enhance regulatory frameworks for mobile
banking operations.
