The digitalization of Estonia began in the 1990s after regaining independence. The goals were to prioritize IT infrastructure, develop digital signatures and tax filing, mobile payments, and e-government services. A key solution was the X-Road system allowing databases to interact securely. Estonia introduced digital ID cards in 2002 enabling online voting, medical records access, and more. Other digital services included e-business registration and e-health records. Estonia's digital transformation has increased government transparency, data exchange, and quality of public services while supporting business and entrepreneurship.
