Descriptive statistics and multiple linear regression tools with the aid of E-Views were used to analyse the data and the findings show that; ATM transactions had a significant negative relationship with the service delivery of deposit money bank in Nigeria( the P-value is 0.01707 while the t-statistics is 2.578346); POS transactions had no significant effect on the service delivery of deposit money bank in Nigeria(P-value is 0.3966 while the t-statistics -0.849849); and Internet banking had the non-significant positive effect the service delivery of deposit money bank in Nigeria (P-value is 0.009 while the t-statistics -3.649302). Overall, the findings suggest that Banks should focus on enhancing the reliability, security, and user experience of ATM and Internet banking services. Addressing common issues such as transaction failures, security concerns, and complicated interfaces could help mitigate the negative impact on customer deposits.
