Sénégalese adults in São Tomé and Príncipe are increasingly engaging with digital technologies for financial transactions, necessitating targeted training to enhance their literacy skills. A mixed-methods approach was employed, including pre- and post-training assessments with quantitative surveys and qualitative interviews to gauge participants' proficiency levels and experiences with digital literacy training programmes. Participants showed a significant improvement in understanding financial concepts through digital means, evidenced by an increase of 25% in self-reported confidence scores from baseline to follow-up. The six-month digital literacy training programme was effective in enhancing the financial management skills of Sénégalese adults aged 30-45, particularly among those with basic computer literacy. Further longitudinal studies should be conducted to assess long-term benefits and potential barriers to sustained use of digital tools for financial transactions.
