Every EU member state must offer at least one EU Digital Identity Wallet by December 2026, yet fewer than one third of member states currently meet the readiness benchmark. Germany is building for 80 million potential users at Level of Assurance High. January 2026 marked the sandbox launch, while the first public stage of the state wallet app is expected in early 2027. SPRIND's German sandbox ran 115 organizations across 150 use cases in six months, making relying-party onboarding the real bottleneck. The business case is concrete: wallet-based onboarding cuts customer cost from 70 to 100 euro down to 3 to 8 euro, turning compliance into ROI.
