The purpose of this session is to explore the design of the future EUDI Wallet ecosystem onboarding from an organizational perspective, using the implementation concept of the German EUDI Wallet ecosystem as a case study. The session will showcase the steps an organization needs to do to register, declare its intended use, and manage potential fees for ecosystem usage. The primary objectives of the EUDI Wallet ecosystem onboarding are to ensure transparency to mitigate misuse, facilitate sustainable public-private financing for the evolving ecosystem and its underlying infrastructure, and promote user-friendly digital processes to encourage widespread adoption by diverse organizations.
