Purpose The current study aims to examine the influence of smart mobile banking services (SMBS) on senior clients’ intention to use banking applications through the moderating role of digital accounting. For that sake, features of SMBS were adopted and included (convenience, security, trust and ease of use). Design/methodology/approach Quantitative approach was used through adopting a questionnaire as a tool of study. The questionnaire was built by researcher through the aid of previous studies; the questionnaire was distributed on a convenient sample of senior bank clients who were above 60 years old as according to UNCEF. After application process, researcher retrieved (306) properly filled questionnaires and SPSS was used to screen and analyze gathered primary data. It is worth mentioning that Cronbach’s alpha scored higher than 0.70 which guaranteed the reliability and consistency of study tool. Findings Results of the study indicated that SMBS influence senior clients’ intention to use these applications and this influence is moderated by ramifications of digital accounting. It appeared that features of SMBS were mainly ease of use and trust, which can effect on how senior clients are convinced to use SMBS. Digital accounting appeared in the sense of guaranteeing a high level of stability and accountability to use SMBS through security, easy access, continuous update and valid presentation of application contents. Results of hypothesis testing accepted the main hypothesis which argued that there was a statistically significant influence of SMBS on senior clients’ intention to use, with a value of (R2 = 0.73, p = 0.5). Based on such results, the study recommended that bank managers should focus on providing reliability and privacy by introducing digital accounting practices in a deeper way to ensure efficiency, reliability and compatibility in the banking services provided. Practical implications Limitations of current study were presented through the application on senior clients who were above 60 years old according to UNICEF. As for the practical implications of study revealed that understanding the factors that influence senior clients’ intention to use SMBS can help banks develop strategies to improve their experience with the banking service. For example, if digital accounting is found to be a significant moderating factor, banks can invest in digital accounting solutions to provide a more user-friendly interface for senior clients. As for theoretical implications, the study can extend the technology acceptance model by examining the moderating role of digital accounting in the relationship between SMBS and senior clients’ intention to use. This can contribute to a better understanding of the factors that influence technology adoption among senior clients. Originality/value The originality of current study is that it focuses on the use of SMBS, which is a relatively new technology that has gained significant popularity in recent years due to its convenience and accessibility. Also, the study examines senior clients, who are an important demographic for the banking industry, as they represent a large portion of the population that is more likely to face challenges in adopting new technologies.
