GTI Switch is São Tomé and Príncipe's national payment switch, introducing the future of payments in São Tomé and Príncipe + revolutionizing transactions across sectors by interconnecting all financial institutions + empowering mobile money, electronic banking, digital wallets, interoperability, and digital payments 1, 2, Sao Tome and Principe report. The solution simplifies financial transactions by enabling users to send and receive money, pay bills, and make purchases through their mobile phones, eliminating the need for physical cash + making payments safer and more convenient.
Major modernisation event: In March 2023, the Board of Directors of the African Development Bank (AfDB) + São Tomé and Príncipe's government signed a $3.2 million loan agreement for upgrade of the National Switch payment system. The upgrade will allow for automatic Real Time Gross Settlement (RTGS) modules + Automated Clearing House (ACH) functionalities which strengthen clearing + settlement of payments — with RTGS allowing high-value transfers to be settled in the Central Bank in real time, reducing liquidity and credit risks within the system.
The structural significance: São Tomé and Príncipe — one of Africa's smallest island nations (~220K population, two-island archipelago) — represents small-state payment-infrastructure-modernisation challenges. PayLogic's role across multiple African national-switch deployments (Comoros National Switch, Equatorial Guinea BANGE Digital, Lesotho LeSwitch) reflects specialised vendor focus on small-African-nation payment-modernisation projects. The AfDB + STP government partnership + $3.2M loan + RTGS + ACH upgrade illustrates multilateral-development-finance support for small-island-state payment-modernisation.
