EUDI Wallet: Digital Identity Is Only the Beginning

Why the real opportunity for Business and Corporate Banking is trusted authority

The European Digital Identity Wallet is easy to understand as an identity initiative.

Who are you? Can you prove it? Can a bank trust the information you provide?

Those are important questions. But for Business and Corporate Banking, they are only the beginning.

Because knowing who someone is does not tell a bank whether that person is entitled to open an account for a subsidiary, approve a payment, sign a mandate or act on behalf of a particular legal entity.

Digital banking therefore needs more than trusted identity.

It needs trusted authority.

And that may ultimately prove to be one of the most important implications of the EUDI Wallet and the proposed European Business Wallet.

Identity solves only part of the problem

Banks already spend considerable effort verifying identities.

During onboarding, customers provide personal and corporate information. Banks verify it, store it and use it to establish the relationship.

But banking relationships do not stop at onboarding.

Once a user enters a digital banking environment, a different set of questions begins:

• Which company does this person represent?
• Which accounts can they access?
• Which actions are they permitted to perform?
• What are their approval limits?
• Can they act independently or is another approval required?
• Are they still authorised to perform this action today?

This distinction matters particularly in Business and Corporate Banking.

A verified identity might establish that a user is exactly who they claim to be. It does not automatically establish that they are authorised to approve a particular transaction on behalf of a particular company.

That second layer is where much of the complexity sits.

From proving who you are to proving what you can do

Today, identity and authority are often managed across different systems and processes.

Authentication may depend on passwords, mobile authenticators, smart cards or bank-specific security devices. Representation rights and payment authorities may sit somewhere else entirely — within bank mandate systems, company access structures or internal authorisation frameworks.

The result is fragmentation.

A user can be successfully authenticated while the question of what they are actually allowed to do still needs to be answered separately.

The EUDI Wallet introduces the possibility of bringing these elements closer together.

For Business and Corporate Banking, the interesting future is therefore not simply one in which a user can say:

“This is who I am.”

It is one in which trusted digital credentials can also help establish:

“This is the organisation I represent, and this is what I am authorised to do on its behalf.”

That turns digital identity from an onboarding mechanism into something much more operational.

The bigger opportunity may be in everyday banking

Much of the discussion around digital identity naturally starts with onboarding and KYC.

That makes sense. These are areas where repeated document collection and verification create obvious friction.

But the more transformative use cases may emerge after the account has been opened.

Consider a treasury professional beginning a normal working day.

They need to access banking services, review accounts and approve transactions. Depending on the banking relationships involved, that may currently mean different authentication methods, different credentials and different ways of proving authority.

Now imagine a trusted framework through which the bank can establish, as part of the interaction:

• who the user is,
• which organisation they represent,
• which authority has been delegated to them,
• and whether they are permitted to perform the requested action.

The interaction starts to look very different.

Authentication and authorisation no longer need to feel like completely separate administrative layers surrounding the banking service. They can become part of the service itself.

Business and Corporate Banking make delegation critical

The distinction between identity and authority becomes particularly important when organisations become more complex.

A business owner may have broad authority across a relatively simple company structure.

A multinational corporate can be very different.

Users may represent different legal entities. Payment rights may vary by account, subsidiary, amount or transaction type. Some actions may require multiple approvals. Responsibilities can change over time as employees move between roles or entities.

Simply knowing someone's identity is therefore not enough.

Banks need to understand the relationship between:

person → organisation → role → authority → action

That is why the proposed European Business Wallet is potentially so important for Business and Corporate Banking.

Its relevance is not merely that companies could hold another form of digital identification. The more interesting possibility is a framework through which organisations can prove corporate identity, exchange trusted credentials and delegate authority digitally.

In other words, the wallet concept starts connecting the individual to the organisation they represent.

The end of document-based trust?

There is another important consequence.

Much of today's trust infrastructure is still document-based.

Companies prove their existence through documents. Representation rights are evidenced through documents. Mandates and authorisations frequently create yet more documents.

These are exchanged, checked, stored and — sooner or later — requested again.

A trusted wallet infrastructure could shift part of that interaction from exchanging documents to exchanging verifiable information.

Instead of asking customers to repeatedly provide evidence and then independently validating it, banks could increasingly receive trusted digital credentials that can be verified directly.

For customers, that could reduce repetitive administrative work.

For banks, it could change how digital journeys are designed.

The objective is not simply to turn an existing PDF into a digital credential.

It is to reduce the need for the PDF in the first place.

One trust layer across more of the banking journey

This is also why EUDI should not be viewed purely as another isolated identity project.

Its potential becomes more interesting when identity, authentication, authority and consent are considered together.

The source material points to a broader convergence with initiatives such as PSD3 and FiDA: trusted identity on one side, trusted access and consent on another, and increasingly digital ways of establishing who may act for an organisation.

For a banking customer, those regulatory and technical distinctions matter less than the resulting experience.

They do not want an identity process, an authentication process, an authorisation process and a consent process.

They want to perform a banking task securely.

The opportunity for banks is therefore to turn those underlying trust mechanisms into a coherent interaction rather than exposing their complexity to the customer.

The design question for banks

The EUDI Wallet therefore raises a broader question for Business and Corporate Banking.

If trusted identity and authority become portable digital capabilities, where should trust live within the banking experience?

Banks will need to think beyond the initial identification step.

They may need to consider how wallet-based credentials interact with:

• existing authentication mechanisms,
• user and role management,
• mandates and signing powers,
• payment approvals,
• account access,
• onboarding and KYC,
• consent,
• and auditability.

This is not simply a question of connecting another authentication method.

It is a question of how a trusted external identity and credential framework fits into the bank's own model for controlling financial actions.

That is a considerably bigger architectural and customer-experience challenge.

From digital identity to digital authority

The EUDI Wallet is often described through the lens of identification.

For Business and Corporate Banking, that description may ultimately be too narrow.

The more significant opportunity is a banking environment in which customers can not only identify themselves digitally, but also prove which organisation they represent and which actions they are authorised to perform.

That could simplify onboarding.

But it could also affect authentication, mandate management, approvals, access rights and the way banks establish trust throughout the customer relationship.

The long-term shift is therefore not simply:

paper identity → digital identity

It is closer to:

fragmented trust → reusable digital trust

And that is why the EUDI Wallet may become far more relevant to everyday Business and Corporate Banking than the word identity initially suggests.
