Main Article Content
This study develops an integrated theoretical framework combining the Technology Acceptance Model (TAM) and the DeLone and McLean's Information Systems Success Model is utilized to analyze the factors influencing the acceptance of electronic payment systems (EPS) in Nigeria .This model includes elements such as system quality, service quality, perceived usefulness, perceived ease of use, perceived risk, trust, and infrastructure challenges are identified as contextual obstacles impacting adoption results in a developing country, On the other hand, users' views and behavioral intentions about EPS utilization are found to be predicted by company reputation. 3,450 valid responses were gathered from clients of particular commercial banks in Southwestern Nigeria using a quantitative survey design. Data were analyzed using multiple regression and principal component analysis.
Findings reveal that system quality (β = 0.237, p < 0.001), service quality (β = 0.410, p = 0.002), perceived usefulness (β = 0.119, p = 0.004), perceived ease of use (β = 0.306, p = 0.001), perceived risk (β = 0.237, p < 0.001), trust (β = 0.010, p < 0.001), and organizational reputation (β = 0.267, p < 0.001) significantly influence users’ attitudes toward EPS adoption. Furthermore, attitude significantly predicts behavioral intention to use EPS.
Infrastructural constraints such as erratic electricity supply, poor internet connectivity, and high operational costs were identified as major barriers to adoption. The study concludes that EPS adoption in Nigeria is shaped by a combined influence of technological, behavioral, trust-based, and infrastructural factors.
The study extends TAM and DeLone–McLean models by introducing infrastructural constraints as contextual determinants in developing economies. The findings offer implications for policymakers, financial institutions, and digital payment service providers in strengthening digital payment ecosystems.
