National CoronaCheck App Development for Dutch Citizens

The project began as a pilot to create a flexible solution for coronavirus access, evolving into a national app for 17 million citizens. The app enabled QR code-based entry at events using test results, later expanding to include vaccination and recovery proofs. Key features focused on privacy, inclusivity, and transparency, ensuring accessibility for all. The team developed four app versions with incremental updates, aligning with national policies and user needs. The app allows users to create and use access proofs, ensuring flexibility and inclusivity across the Netherlands. The project successfully transitioned from a pilot to a nationwide solution, addressing pandemic challenges through innovative design and user research.
