This post will be updated after the Summit with on-the-ground notes; the framing below reflects the agenda as published on 27 April 2026.
A summit that has shifted gears
On 28 and 29 April 2026, Bitkom hosts the eIDAS Summit in Berlin and online. Day one is on-site at the Representation of the State of Baden-Württemberg in Berlin and runs in German with a national focus; day two is in English and online for a European audience. The keynote line-up is heavier than in any previous edition: Federal Digital Minister Dr. Karsten Wildberger leads the BMDS perspective, Norbert Sagstetter speaks for the European Commission's Digital Identity Unit, Dr. Markus Reichel covers the rapporteur position from the CDU/CSU group in the Bundestag, and Christina Raab, Bitkom Vice President and Accenture's DACH CEO, opens the industry side.
The reason this Summit is worth a separate post is not the keynote roster. It is the way the agenda has been structured. Earlier eIDAS Summits were protocol-led — sessions on OpenID4VP, on mDoc, on selective disclosure, on cryptographic suites. This one is sector-led: the published programme tracks ePrescription, bank account opening, SIM and eSIM registration, mobile driving licence, and electronic government services as the structural lens. That shift is the signal. Two days, five takeaways every relying party and merchant should leave with — even those who never log into the live stream.
Why this summit is different
For three years the public eIDAS conversation has been a protocol conversation. Wallet vendors argued about formats, profile authors argued about scope, and large-scale pilots produced reports that were read mostly by other large-scale pilots. The Summit's own framing for 2026 — "Where does real added value emerge?" — drops that frame entirely. The question is no longer how the wallet should work. It is what merchants, banks, telcos, hospitals, and transport operators are actually going to do with it in the eight months before the 24 December 2026 EU deadline and the eight months after.
That is a maturity signal. It also means the Summit will, for the first time, be useful to non-specialists. A merchant integration lead who has been watching from the sidelines will get more from this two-day agenda than from any of the protocol-heavy events that preceded it. Below are the five things to actually track.
Takeaway 1 — Sector-specific use cases are now the lens
The shift from protocol-led to sector-led is the single most important framing change of the year. Each session on the programme is built around a vertical, and each vertical answers a different question.
Electronic government services. Day one features extensive coverage of how the wallet plugs into existing eGov stacks — service portals, social-benefit applications, registry queries. Pay attention to the integration cost: how much existing eID work has to be re-tooled, and how much can be re-used.
Banking. Bank account opening is the workstream where Article 5f(2) of eIDAS 2 bites first. By end of 2027, banks and credit institutions across the EU must accept the wallet for identity verification when the user requests it. Spain's Royal Mint pilot, German Sparkassen and Volksbanken positions, and the early French Identité-bank dialogues are all expected to surface here.
Telecommunications. Deutsche Telekom is presenting on a multi-wallet SIM and eSIM registration architecture. This is the dossier merchants in regulated markets — gambling, alcohol delivery, prepaid SIM — should watch hardest, because telcos have been forced to handle multiple national wallet formats long before retail will be.
Mobility. The mobile driving licence (mDL) workstream brings in the cross-border interop file. Cross-border car rental, electric-vehicle charging onboarding, and toll systems all live here.
Healthcare. ePrescription has been the canary use case across POTENTIAL and DC4EU. Selective disclosure works there because the data set is small and the privacy stakes are clear. The healthcare track is where the wallet's "minimum data" promise will either be vindicated or quietly downgraded.
For a relying-party integration lead, the take-away is: pick the vertical closest to your own checkout, then read the others as cross-vertical lessons. The mistakes telcos are making in 2026 are the mistakes retail will make in 2027.
Takeaway 2 — The 100-company MoU is your integrator directory
Buried in the Bitkom press release of 13 April is a number that has not yet been read for what it is: more than 100 companies have signed a Memorandum of Understanding with the BMDS to ship integrations on launch day. That MoU is not a marketing artefact. It is, in effect, the most authoritative integrator directory the German wallet ecosystem currently has — months ahead of any equivalent published list from the EU Commission or any member state.
Day one of the Summit is where MoU signatories surface in panel discussions. Some are large platforms (Deutsche Bahn, Deutsche Telekom, the major insurers); others are smaller integration vendors who will end up doing the bulk of the actual checkout work. Treat the published participant list as a procurement starting point. If you are a German merchant looking for a wallet-integration partner with January 2027 production credentials, the MoU is the most reliable filter you will find before Q3 2026.
For non-German merchants, the same logic holds with a delay. Whoever ships first in Germany ships fastest everywhere else. The integrators who land their first production wallet flow on 2 January 2027 are the ones who will bid for your French, Italian, and Dutch integrations in Q2 2027.
Takeaway 3 — The European Business Wallet is the B2B sibling
Day two has a session block on the European Business Wallet. That is the one most merchant teams will skim past, because the name does not yet read as urgent. It will. The European Business Wallet is the Commission's parallel B2B identity stack — a wallet for legal persons rather than natural persons — and it is on a timeline that runs roughly six months behind the EUDI Wallet. The Summit's own framing treats it as a sibling, not a successor.
Why this matters for merchants: B2B onboarding, supplier identity, invoicing, and supply-chain due diligence are all going to migrate onto Business Wallet rails over 2027–2028. Companies that have already integrated the EUDI Wallet for natural-person identity at checkout will be in a strong position to plug the Business Wallet into their merchant onboarding and supplier-management stacks without a second redesign. Those who have not will run two parallel projects.
If you operate a marketplace, a B2B SaaS with company verification, an e-procurement platform, or a regulated-supplier onboarding flow, the Business Wallet sessions are the ones to take notes from. Expect Day 2 to surface the first concrete timeline commitments from DG CONNECT.
Takeaway 4 — Germany's 2 January 2027 launch sets the cross-border tone
Germany goes live on 2 January 2027. That date is now confirmed in Bitkom's own communications and is referenced repeatedly across the Summit programme. Italy is already partially live in the IO app; Luxembourg has wrapped its large-scale pilot; France and Spain are publicly testing sandboxes. But Germany is the first launch that will combine a 24/7 production user base, a regulated-vertical merchant requirement (banks under Article 5f(2), age-restricted commerce under evolving national age-assurance rules), and a cross-border traveller flow.
For merchants in any other member state, the German launch is the de-facto cross-border test. A French e-commerce site selling into Germany, a Hungarian gambling operator with German-speaking customers, an Irish marketplace with cross-border buyers — all of them will see German wallets present at their checkout in the first week of 2027, regardless of whether the merchant has done any explicit cross-border work. The Summit will surface the first concrete numbers on cross-border presentation rates, format compatibility, and verifier-side error patterns.
The takeaway: prioritise integration testing against German wallet test environments before testing against domestic ones, even if your domestic launch is months away. Germany is going to be the place where cross-border interop succeeds or fails first, and the public failure mode will be on every merchant ops dashboard within hours.
Takeaway 5 — The policy-vs-merchant gap will be visible
Three of the four headline keynotes at the Summit are policymakers: Wildberger from BMDS, Sagstetter from the Commission, Reichel from the Bundestag. The fourth, Raab, speaks for industry. The remaining sessions split roughly between vendors, regulators, and a thin band of relying-party voices. That ratio is not unusual for a digital-identity event. It is becoming a problem.
Three live policy questions will be visible in the Q&A whether or not the agenda gives them room. First: the Anti-Money-Laundering Authority (AMLA)'s level-of-assurance position on wallet-mediated KYC. Banks have been told to accept the wallet, but the LoA mapping between wallet attestations and AMLA's requirements has not yet been definitively published. Until it is, every bank legal team has to make a defensive interpretation.
Second: Implementing Regulation 2026/798 on remote onboarding using qualified electronic attestations of attributes. The text is in force; the operational profiles are still settling. Vendors and merchants are reading it differently from the Commission. The Summit will be the first event where those readings collide in person.
Third: the operational status of the Article 5b register — the public list of registered relying parties, including merchants, that the wallet ecosystem depends on for trust decisions. Several member states have not yet stood up their national register. Without it, the wallet-side trust check fails or has to be bypassed. Watch ETSI TS 119 475 v1.2.1 for the technical reference, and watch the panel Q&A for the political reality.
The merchants in the room will absorb the consequences of every policy choice debated on stage. That is the asymmetry to listen for.
A living document
This post is a preview, not a recap. We will update it after 29 April with verified quotes from Wildberger and Sagstetter, the headline numbers from the German MoU panel, and any concrete timeline commitments on the European Business Wallet and the Article 5b register. If you are reading this before the Summit closes, the framing above reflects the published programme as of 27 April 2026; if you are reading it after, the updates will be appended below the line.
For German merchants, day one is the priority. For European merchants outside Germany, day two is the one to clear the calendar for. For those who cannot attend either, the Bitkom Summit page will publish session recordings, and the relevant excerpts will be linked from this post once available.
Eight months out from launch, two days of sector-led, merchant-relevant content is genuinely worth more than two months of newsletters. That is what makes this Summit different.
