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 Personligt ID in your wallet. With it she collects all three into the business wallet, and the NAU answers her application while she waits.
Sådan fungerer det
Tre roller, to protokoller
Alt på denne side følger de europæiske standarder for digital identitet. Terminologien nedenfor er den samme, du finder i specifikationerne, så du nemt kan sammenholde det, du ser, med det, du læser.
Udsteder
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.
Indehaver
Dig. Dine attester ligger i tegnebogen på din telefon, ikke i vores database. Du bestemmer hver gang, om du vil dele, og hvad.
Verifikator
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.
Udstedelse: OpenID4VCI
Du scanner et tilbud om en attest. Din tegnebog henter attesten fra udstederen og gemmer den, kryptografisk bundet til en nøgle, som kun din telefon råder over.
Fremvisning: OpenID4VP
En verifikator sender en forespørgsel, der beskriver, hvad den har brug for. Din tegnebog viser dig anmodningen, og kun det, du godkender, sendes tilbage, signeret.
Hvorfor verifikatoren lærer mindre, end du måske tror
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.
Trin 1
Brug en kompatibel EUDI-tegnebog
Du skal bruge en tegnebogs-app for at modtage og dele attester. Enhver tegnebog, der understøtter OpenID4VCI og OpenID4VP, kan opbevare dem, men den skal også acceptere attester fra en udsteder, den endnu ikke kender, og det gør ikke alle.
Trin 2
Udsted dine testattester
Scan the QR code with your wallet to receive the Personligt ID. The data is fictional: you are receiving Karin's Personligt ID, so nothing about you is stored anywhere.

Personligt ID (SD-JWT VC)
Issue the Personligt ID first: it is what identifies Karin at each of the four portals.
Personligt ID (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.

Trin 3
Brug attesterne i praksis
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 Personligt ID
Issue the Personligt ID 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 Personligt ID (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 Personligt ID.
- 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.
