The findings reveal that all four variables significantly and positively influence financial inclusion, with Digital Banking Adoption exerting the strongest impact. The model explains 68% of the variance in Financial Inclusion, underscoring the importance of digital transformation, trust-building, robust security, and customer satisfaction in enhancing financial accessibility.
