Architecture and Technical Approach
Germany and Poland have taken fundamentally different paths to digital identity, shaped by their distinct national priorities. Germany's AusweisApp is built on the Signed Credential with Cloud Support (C') model, developed through SPRIND in partnership with BSI and Bundesdruckerei. This architecture places the hardware secure element of the German eID card at the center of every credential operation.
Poland's mObywatel, developed by Centralny Ośrodek Informatyki (the Central IT Center) under the Ministry of Digital Affairs, takes a government-documents-first approach. Rather than focusing on authentication infrastructure, mObywatel prioritized making government documents accessible on smartphones. The mDowód (mobile ID) system allows citizens to carry a legally valid digital ID card, and the app has expanded to include driving licenses, vehicle registrations, and student IDs.
The version 3.0 upgrade transforms mObywatel into a full EUDI Wallet, adding verifiable credential capabilities on top of the existing document repository. Germany's approach is more architecturally pure, designed from the ground up for the EUDI credential model, while Poland's approach is more pragmatic, extending a proven and massively adopted platform with new capabilities.
Security Models Compared
Germany's security model is anchored in BSI certification, one of Europe's most rigorous cybersecurity evaluation frameworks. The German eID card contains a certified chip meeting EAL5+ standards, and every NFC communication session between the card and AusweisApp is encrypted and mutually authenticated. This hardware-first approach has proven its resilience over 15 years of production use.
Poland's mObywatel security model is more software-centric, relying on device-level security features and server-side verification. The mDowód system uses QR codes and NFC for in-person verification, with back-end connectivity to government databases ensuring document authenticity in real time. While this model lacks the dedicated hardware secure element that Germany employs, it benefits from continuous server-side monitoring and instant credential revocation capabilities.
For the EUDI Wallet upgrade, Poland is strengthening its security architecture to meet eIDAS 2.0 Level of Assurance High requirements. This includes enhanced device binding, cryptographic attestation, and integration with the EU Trust Framework. Germany's existing BSI-certified infrastructure already meets these requirements.
User Experience and Adoption
Poland's mObywatel is one of the great success stories of European government digitalization. With over 20 million active users representing more than half of Poland's adult population, the app has achieved adoption rates that most EU digital identity projects aspire to. The key to this success was Poland's practical approach: instead of asking citizens to learn a new authentication concept, they digitized the documents people already carry.
Germany's AusweisApp has a more technical user experience. The requirement to hold the eID card against the smartphone for NFC authentication adds a physical step that Poland's software-only approach avoids. However, German users who have completed the initial setup report confidence in the system's security.
The transition to EUDI Wallet capabilities will challenge both countries differently. Poland must convince its 20M+ users that the upgrade to mObywatel 3.0 adds value without disrupting the familiar experience. Germany must use the EUDI Wallet launch as a catalyst for broader adoption.
Cross-Border Interoperability
Cross-border interoperability between Germany and Poland is particularly important given the significant cross-border workforce. Hundreds of thousands of Polish citizens live and work in Germany, and many German businesses operate in Poland. Under eIDAS 2.0, a Polish worker in Germany must be able to present mObywatel credentials to German employers and government services.
Both countries are participating in the EU Large Scale Pilots to validate cross-border scenarios. The standardized credential formats ensure that the different technical architectures are transparent to relying parties. Whether a credential comes from a BSI-certified hardware secure element or mObywatel's server-verified document store, the verification protocol is the same.
Germany's open source approach through OpenCoDE allows Polish developers to understand the AusweisApp verification protocol, while Poland's extensive real-world deployment experience provides valuable lessons for cross-border integration testing.
Which Should You Choose?
Use the wallet provided by your country of residence. German residents use AusweisApp; Polish residents use mObywatel 3.0. Both will work smoothly across all EU member states once fully launched.
Germany represents the gold standard in security certification and hardware-backed identity, while Poland demonstrates what mass adoption looks like with over 20 million users on a single government identity platform. Both models contribute valuable lessons to the broader EUDI ecosystem.
