The term Digital Public Infrastructure (DPI) is primarily used in two ways: 1. To describe *an approach* to addressing socio-economic problems at population scale. This approach combines open technology standards with robust governance frameworks to encourage private and community innovation to address societal scale challenges such as financial inclusion, affordable healthcare, quality education, climate change, access to justice and beyond. 2. To describe *real-world examples* of that approach represented by well-designed, population-scale infrastructure that abide by the [principles](/the-dpi-wiki/dpi-tech-architecture-principles.md) of the DPI approach. Examples include India's digital identity system *Aadhaar*, Brazil's payment system *Pix*, Estonia's data-sharing platform *X-Road*, Singapore’s national digital ID *SingPass*, Thailand’s instant payment system *PromptPay*, and Argentina’s *Mi Argentina* digital services platform. --- # Agent Instructions This documentation is published with GitBook.
