Admitted to the market.Karin arranges it from the wallet.
Hanze Staffing places workers, and from 2027 it may only do so if the NAU has admitted it. Karin de Wit is the one who has to arrange that: a register extract from the KVK, a certificate of conduct from Justis and a tax declaration from the Belastingdienst — three authorities that used to mean scans, e-mail and waiting. This playground puts her Personalausweis in your wallet. With it she collects all three into the business wallet, and the NAU answers her application while she waits.
So funktioniert es
Drei Rollen, zwei Protokolle
Alles auf dieser Seite folgt den europäischen Standards für digitale Identität. Die Begriffe unten sind dieselben wie in den Spezifikationen, damit Sie das Gesehene dem Gelesenen zuordnen können.
Aussteller
The party that states something about you and signs it. Here there are four: the KVK issues the register extract, Justis the certificate of conduct, the Belastingdienst the tax declaration and the NAU the admission itself.
Inhaber
Sie. Ihre Nachweise liegen in Ihrer Wallet auf Ihrem Telefon, nicht in unserer Datenbank. Sie entscheiden jedes Mal neu, ob Sie teilen, und was.
Prüfer
The party that asks for proof. The NAU is the verifier that matters: it checks that all three attestations are valid, unrevoked and about the same company before it decides. FlexGate then verifies only the NAU's conclusion.
Ausstellung: OpenID4VCI
Sie scannen ein Nachweisangebot. Ihre Wallet holt den Nachweis beim Aussteller ab und speichert ihn, kryptografisch gebunden an einen Schlüssel, den nur Ihr Telefon besitzt.
Präsentation: OpenID4VP
Ein Prüfer schickt eine Abfrage, die beschreibt, was er benötigt. Ihre Wallet zeigt Ihnen die Anfrage, und nur was Sie freigeben, geht signiert zurück.
Warum der Prüfer weniger erfährt, als Sie vermuten
Credentials in SD-JWT VC format support selective disclosure. The NAU does not ask which people Justis screened, and it does not ask for the loonheffingennummer: it asks whether the obligations were met. A paper VOG cannot leave those out; this can.
Schritt 1
Nutzen Sie eine kompatible EUDI-Wallet
Sie brauchen eine Wallet-App, um Nachweise zu empfangen und zu teilen. Jede Wallet, die OpenID4VCI und OpenID4VP spricht, kann sie aufbewahren. Sie muss aber auch Nachweise von einem ihr noch unbekannten Aussteller annehmen, und das tut nicht jede.
Schritt 2
Stellen Sie Ihre Testnachweise aus
Scan the QR code with your wallet to receive the Personalausweis. The data is fictional: you are receiving Karin's Personalausweis, so nothing about you is stored anywhere.
Ihre Nachweise
0 / 1
Personalausweis (SD-JWT VC)
Issue the Personalausweis first: it is what identifies Karin at each of the four portals.
Personalausweis (SD-JWT VC)
Karin's name, date of birth, nationality and address. It shows who she is when she signs in at the portals that issue Hanze Staffing's attestations.

Schritt 3
Nutzen Sie die Nachweise im Ernstfall
Issuing a credential is only half the story. The KVK, Justis, the Belastingdienst, the NAU and FlexGate are live portals; together they take Hanze Staffing from a registration to an assignment.
Karin gets Hanze Staffing admitted
Admission to the labour-hire market
flexgate.acc.credenco.comKarin de Wit signs for Hanze Staffing, a company that places workers with other employers. The last time she arranged this it took three authorities, a scanner and a fortnight of waiting. From 1 January 2027 the Wtta closes the market to anyone the NAU has not admitted, and admission means proving who the company is, that its directors were screened and that it meets its tax obligations. In this demo you are Karin: you collect the three proofs into the business wallet, apply once, and register for an assignment with the admission you get back.
What happens next
Get Karin's Personalausweis
Issue the Personalausweis above and store it in the wallet app on your phone. It is what identifies Karin when she signs in; the attestations about Hanze Staffing go into the business wallet.
Collect the register extract at the KVK
At mijnkvk.acc.credenco.com Karin collects the company registration (EUCC) into Hanze Staffing's business wallet: the name, the KVK number, the legal form and who may sign for it.
Apply for the VOG rechtspersonen at Justis
At justis.acc.credenco.com Karin shares the registration and applies for a certificate of conduct for the company. Justis screens the directors and issues the VOG into the same wallet, stating the purpose: admission to the labour-hire market.
Get the tax declaration from the Belastingdienst
At belastingdienst.acc.credenco.com Karin shares the company's identity and receives the Verklaring nakoming fiscale verplichtingen: payroll tax and VAT, assessed over the past year, with no amounts in it.
Apply for admission at the NAU
At nau.acc.credenco.com the three attestations go across in one request. The NAU checks signature, origin and validity in seconds, judges the application and issues the admission back into the same wallet.
Register for an assignment at FlexGate
FlexGate is the inlener. It asks only for the admission and the register extract: the NAU already weighed the VOG and the tax declaration, and an inlener that asked for them again would be redoing an authority's work.
You are missing Personalausweis (SD-JWT VC). You can continue, but signing in at the portals will stop when they ask for it.
If something goes wrong
- "No credentials available" means the attestation being asked for is not in the wallet you are sharing from. The three that matter live in the business wallet, not in the personal one that holds the Personalausweis.
- If an application stops halfway, start again from the portal's home page rather than reloading a page you already scanned into: every attempt gets its own code.
