After introducing EUDI Wallet verification, the most important business metrics to track fall into four categories: onboarding conversion, operational cost, compliance performance, and return on investment. Organizations that define these metrics before go-live get a clear baseline to measure against, which makes it much easier to demonstrate the value of the implementation. The sections below walk through each category with concrete guidance on what to measure and when.
Which metrics change most immediately after EUDI Wallet goes live?
The metrics that shift fastest are those tied directly to the verification step itself: the time it takes to complete identity verification, the drop-off rate at that step, and the share of verifications that succeed on the first attempt. These numbers often change within days of going live, because wallet-based verification replaces a manual or document-upload step with a cryptographically signed presentation from the user’s wallet.
Alongside those, keep an eye on error rates and support ticket volume related to identity checks. If users previously struggled with document uploads or knowledge-based questions, you will typically see a drop in failed verifications and a corresponding drop in support contacts. That shift is one of the clearest early signals that the new flow is working.
A practical starting point is to record your baseline numbers for each of these metrics in the week before go-live. Without that reference point, it is difficult to separate the effect of the wallet integration from other changes happening in the same period.
How does EUDI Wallet verification affect onboarding conversion rates?
EUDI Wallet verification tends to improve onboarding conversion by reducing the friction at the identity check step. Users who already have a wallet with their personal identification data loaded can share verified attributes in a single interaction, without uploading documents or waiting for manual review. Fewer steps and less waiting generally mean fewer drop-offs.
The size of the improvement depends on how cumbersome the previous process was. Organizations that relied on manual document review or asynchronous verification flows tend to see the largest gains, because the wallet replaces a multi-day wait with a same-session check. Organizations that already had a smooth digital verification flow may see a smaller but still measurable improvement.
To measure this properly, track conversion at the identity verification step specifically, not just overall onboarding completion. A funnel view that shows where users drop off at each stage makes it possible to isolate the effect of the wallet step. Segment by user group where possible: users who complete verification with a wallet versus those who use an alternative method, so you can compare the two paths directly.
One nuance worth noting: conversion rates reflect user experience, but they do not tell you about data quality. A faster flow that delivers lower-quality identity data is not an improvement. Wallet-based verification delivers attributes at the highest assurance level, which means the data arriving in your business process is verified at source. That combination of speed and data quality is what makes the metric meaningful for regulated sectors such as financial services and healthcare.
What operational cost metrics should organizations measure?
The most relevant operational cost metrics after introducing EUDI Wallet verification are the cost per verified identity, manual review hours, and the volume of identity-related support contacts. Each of these tends to decrease when verification moves from a document-based or manual process to wallet-based presentation, because the verification itself is handled by the wallet infrastructure rather than by internal staff.
Track the following cost-related indicators:
- Cost per completed verification: the total cost of running your identity verification process divided by the number of successful verifications in a given period.
- Manual review volume: the number of cases that require a human to review identity documents or resolve a failed check.
- Support ticket volume for identity issues: contacts related to failed logins, locked accounts, or identity verification errors.
- Re-verification rate: how often users need to go through the identity check again because the first attempt failed or the data was incomplete.
- Time to verified status: the average time from a user starting the verification flow to the point where your system has a confirmed, usable identity record.
These metrics are most useful when tracked over a rolling period rather than as a one-time snapshot. Operational savings from wallet-based verification often accumulate gradually as more users adopt the wallet flow and as your team becomes familiar with the new process.
How should compliance and audit performance be tracked?
Compliance performance after EUDI Wallet verification is best tracked through a combination of process metrics and audit-readiness indicators. The core question is whether your organization can demonstrate, at any point, that identity verification was performed correctly and that the data used in each transaction came from a verified source.
Useful compliance metrics include:
- Attribute scope adherence: confirm that every data request stays within the attributes registered under CIR (EU) 2025/848. Requesting more attributes than registered is grounds for revocation of your registration, so this is a critical control point.
- Verification completeness: the share of identity checks that include all three required verification steps: the issuer’s signature against the national trusted list, the revocation status of the attestation, and the wallet unit attestation confirming the presenting wallet runs on a certified wallet solution.
- Audit trail completeness: whether your logs confirm that you stayed within your registered attribute scope, without recording the full set of presented attributes in a way that undermines selective disclosure.
- Incident rate: the number of verification events that triggered a compliance review or exception process.
- Time to produce audit evidence: how long it takes your team to pull together the documentation needed for a regulatory audit or internal review.
One important distinction: the transaction dashboard in the EUDI Wallet is designed for the user, not for the relying party. Users can see which organizations received which data and can submit deletion requests. Your own logging should focus on confirming that your requests stayed within scope, not on replicating the full attribute set that was presented.
For organizations in regulated sectors, compliance metrics connect directly to obligations under eIDAS 2.0 and, from July 2027 onwards, the new AML regulation. Building your measurement framework now, before the private sector acceptance deadline of 24 December 2027, gives you time to identify and close gaps before they become audit findings. Organizations in government and pharmaceuticals face similar pressures and benefit from the same structured approach.
When should organizations expect measurable ROI from EUDI Wallet verification?
Most organizations see the first measurable signals of ROI within three to six months of go-live, primarily through reduced manual review costs and lower support volumes. Conversion improvements are often visible sooner, sometimes within the first few weeks, but they need a few months of data to confirm as a stable trend rather than a launch effect.
The timeline varies depending on three factors: how much friction existed in the previous verification process, how quickly users adopt the wallet flow, and how broadly the wallet integration is deployed across your services. An organization that replaces a slow, manual KYC process with wallet-based verification in a high-volume onboarding flow will see ROI faster than one that adds wallet acceptance as an optional alternative to an already-smooth digital process.
Longer-term ROI, typically visible after twelve months, comes from the reusability of verified identity data across interactions. When a user’s identity is verified once at the highest assurance level, that verified status can carry through to subsequent logins and signing sessions without repeating the full check. That reuse reduces per-transaction costs over time and is one of the structural advantages of wallet-based identity over session-by-session document verification.
Set realistic expectations with stakeholders by separating short-term operational savings from longer-term strategic value. The operational savings are measurable and relatively predictable. The strategic value, such as being ready for the private sector acceptance deadline and building a foundation for cross-border identity, is harder to quantify but matters for organizations planning their digital identity approach beyond 2027.
How the ID Connector helps you track and act on these metrics
The ID Connector is an integration that lets relying parties accept every certified European wallet, whatever Member State issued it, for identification, login and qualified signing. EUDI Wallet acceptance comes first; the same interface also carries other IDs, such as national eIDs, bank IDs and identity documents, inside and outside the EU.
For the metrics covered in this article, the ID Connector handles the verification steps that underpin your measurement framework. Identity attributes arrive cryptographically signed by the issuing party, so the data entering your business process is verified at source. The integration manages trust verification against national trusted lists, revocation status checks, and wallet unit attestation validation, which means the three verification steps required for compliance are handled within the connection rather than left to your internal systems to implement separately.
This matters for your metrics in concrete ways:
- Verified attributes are reusable across identification, login, and signing sessions, which reduces per-interaction costs and supports your cost-per-verification tracking.
- The integration stays within the attribute scope registered under CIR (EU) 2025/848, which supports your compliance logging and audit trail.
- One connection covers 27 or more certified European wallets alongside other identity methods, so your conversion and adoption metrics reflect a single, consistent flow rather than multiple parallel integrations.
The ID Connector is used by organizations in financial services, healthcare, pharmaceuticals, and government. If you want to see how it fits your specific verification setup, get in touch with TrustTech.
