## Practices

* Encourage a mixed-financing approach for DPI, leveraging both public funds and contributions from private sector partners, as seen with Belgium’s Itsme platform. Promote the adoption of a not-for-loss revenue model, like India’s Unified Payments Interface (UPI), where sustainability is achieved through low transaction fees or data services.
