EUDI Wallet: from innovation to a trusted European infrastructure
The European digital identity is shifting from a discussion about innovation to one about implementation. The challenge is no longer simply to demonstrate that a digital wallet can issue, store or present credentials, but to build an interoperable ecosystem that is useful and adoptable for citizens, businesses and public authorities.

The wallet as a gateway
The EUDI Wallet should not be seen merely as an app for digital identification, but as the gateway to a new digital trust infrastructure in Europe.
For years, discussions about digital identity, wallets and verifiable credentials have been closely linked to innovation. Pilot schemes, proof-of-concept trials, industry demos and use cases have demonstrated how an individual or organisation could receive, store and present verifiable information. That work has been necessary to demonstrate the possibilities, but the context is changing.
With eIDAS2, the ARF and the national implementations of the EUDI Wallet, the conversation is beginning to shift. It is no longer just about proving that the technology works, but about defining how it integrates into real-world services, how wallets interoperate, how credentials are verified, how parties are identified, and how all of this is turned into a useful experience.
The wallet will be the part that many people see, but it will not be the only important element. The real change will lie in the ecosystem that is built around it: issuers, verifiers, trusted services, credentials, representations, permissions, integrations and processes capable of handling verifiable data in a secure and recognised manner.
From innovation to implementation
Having worked on projects related to wallets, verifiable credentials and SSI use cases, it is becoming increasingly clear to me that the challenge no longer lies solely in explaining the paradigm. The challenge lies in making it work within existing systems, organisations and processes, with their limitations, their users, their technical dependencies and their resistance to change.
SSI has long been a powerful promise: giving more control back to the user, reducing friction in data verification, avoiding the unnecessary exchange of full documents and enabling individuals and organisations to prove attributes more securely. But a technological promise does not automatically translate into adoption.
The EUDI Wallet could mark a turning point because it introduces a common European framework, regulatory direction and real pressure for implementation. That does not mean everything will be resolved easily, but it does mean we are moving beyond merely discussing future scenarios. Member States are making progress on their own reference wallets, and organisations are beginning to view this ecosystem not as a curiosity, but as something that could impact their digital processes.
This presents a significant opportunity for the product. Not all solutions will need to be a country’s official wallet to add value. There will be scope to issue credentials, verify submissions, integrate wallets into existing processes, design consent experiences, build connectors, adapt sector-specific use cases, or help organisations operate within this new framework.
The difference between innovation and implementation lies precisely there. In innovation, it is enough to demonstrate that a credential can be issued and verified. In implementation, one must resolve what happens when the user does not understand the workflow, when a credential expires, when one organisation acts on behalf of another, when legacy systems need to be integrated, when exceptions arise, or when the use case requires legal validity, traceability and operational support.
Implementation will be the real challenge
Regulatory and technical progress alone does not guarantee smooth adoption. Digital identity already faces well-known hurdles: digital certificates that are difficult to use, administrative processes that are not user-friendly, applications that require too many steps, and users who are slow to embrace each new model. The EUDI Wallet could simplify many things, but only if it is designed with real-world usability in mind, rather than the complexity of the ecosystem.
Utility rather than obligation
It is likely that many people will start using the EUDI Wallet because certain public or private services begin to require it. But an obligation does not always lead to understanding. For the model to work, users will need to feel that the wallet saves them time, reduces red tape or gives them more control over their data—not that it adds a new layer that is difficult to understand.
User experience for non-digital users
We cannot design this ecosystem with only users who are accustomed to digital wallets, digital credentials or advanced authentication in mind. Many people still struggle with digital certificates, Cl@ve or basic administrative procedures. If the user experience fails to clearly explain concepts such as credentials, presentation, issuer, verifier or consent, adoption could become yet another barrier.
Integration into real-world processes
The wallet should not force the user to mentally step away from the task they are performing. Whether someone is opening a bank account, accessing a public service or sharing health information, digital identity must be seamlessly integrated into that process. Success will depend on the verification being straightforward, proportionate and useful at the right time.
Explainable trust
Trust cannot depend solely on the system being technically secure. It must also be transparent. Users need to understand what data they are sharing, with whom, for what purpose, for how long, and what the consequences are of accepting or rejecting a request. Without that clarity, the wallet may be interoperable and secure, but it will continue to breed mistrust.
Business Wallet as an opportunity
The citizen wallet will be key, but a significant part of the opportunity will lie in how organisations adopt verifiable identity to interact with one another, with public authorities and with customers.
In the business world, digital identity is not limited to knowing who a person is. Often, the key issue is knowing in what capacity they are acting: whether they represent a company, whether they are authorised to sign, whether they can request a service, whether they belong to a specific organisation, or whether they are authorised to carry out a particular transaction.
This is where the Business Wallet opens up a particularly interesting avenue. It can enable an organisation to manage corporate attributes, powers of representation, authorisations, business credentials or relationships with employees and third parties in a more verifiable manner. This can have an impact on B2B and B2G processes, procurement, compliance, signing, onboarding, corporate KYC or the exchange of documentation.
The opportunity lies not only in digitising what was previously done using PDFs, certificates or manual checks. It lies in redesigning processes where trust between parties can be verified in a more agile, traceable and interoperable manner. A company does not need to ‘have a wallet’ simply because it is novel; it needs one if it helps it to operate better, demonstrate better and verify better.
In sectors such as banking, public administration, healthcare and business services, this layer can reduce a great deal of friction. Opening accounts, accrediting representatives, validating permits, accessing services, submitting documentation and verifying requirements are all processes where verifiable identity can add value if properly integrated.
Furthermore, the implementation of reference wallets in different countries opens up a business opportunity for solutions capable of adapting to national frameworks, sector-specific requirements and the specific needs of each organisation. The value will not lie solely in creating a wallet, but in building the components that enable the ecosystem to function: issuance, verification, integration, user experience, credential management and adaptation to specific use cases.
For this reason, the future of SSI in Europe should not be viewed solely through the lens of the citizen wallet. We must also consider organisational identity, trust services and business workflows. If the EUDI Wallet represents a new layer of trust for individuals, the Business Wallet can become an operational layer enabling organisations to interact with greater security, efficiency and recognition.
From standard to real-world use
The challenge will not simply be to comply with the framework, but to turn it into products, processes and experiences that are worth using.
The EUDI Wallet can help establish a common digital trust infrastructure in Europe, but its success will not depend solely on standards, regulation or national implementations. It will depend on citizens, businesses and public administrations finding it genuinely useful, and on the solutions built around it not passing on all the technical complexity to the user.
For those of us working in digital product development, this shift calls for a very practical approach. It is no longer enough to understand SSI, verifiable credentials or wallets as concepts of innovation. We must now think about adoption, interoperability, governance, business, user experience, integration with existing systems and use cases that can be sustained beyond a demo. European digital identity is entering a phase where the question is no longer just what can be done, but how to make it useful, reliable and usable at scale.
Let’s talk about digital identity and trust
I work on digital products where identity, data, trust and user experience need to coexist in a way that makes sense. If you’re exploring use cases involving wallets, verifiable credentials or trust-based digital services, let’s have a chat.
