One platform underneath all three integration forms
The same purpose binding, the same data minimization, the same log – whether login, check or age gate.
Purpose binding per client
Every client has an attribute policy and a visible purpose text. Only the intersection of scope and policy is ever requested.
Data minimization
DCQL requests exactly and only what the purpose requires – never more.
Consent log
An append-only log of every release – with a purpose snapshot, but no attribute values.
Pairwise subjects
A separate, non-correlatable subject per tenant – portals cannot link users across each other.
Account recovery
A newly issued e-ID is never silently linked to an existing account. Login pauses until the one-time recovery code is provided.
Swiss hosting
Operated in Switzerland, multi-tenant, with an admin console and audit log – with your own verifier DID on request.
Provica in action
One QR code, four steps – and your portal knows the verified attributes.
The login page of an integrated portal: "Log in with e-ID", QR code for the swiyu wallet, visible purpose text.
The flow: portal integrates via OIDC, the user scans the QR code, the wallet presents selectively, Provica delivers verified claims.
Build it yourself, or use Provica
The swiyu verifier is open source – it's operating it that hurts.
Operate a verifier
Yourself: deploy and operate the swiyu verifier, manage signing keys as SEC1, response encryption is mandatory – plus checkout logic and proof management if you need age verification in a shop. With Provica: done.
Track swiyu changes
Yourself: keep VCT and issuer DIDs current while the documentation lags behind. With Provica: we keep it current for you.
Purpose binding and consent
Yourself: build purpose binding, consent and data minimization from scratch. With Provica: built in, from day one.
Tenants and audit
Yourself: solve tenants, key rotation and audit logs on your own. With Provica: multi-tenant, with an admin console and audit log.
How the OIDC login works
One QR code. Four steps. Done.
Portal integrates via OIDC
A standard OIDC client (Authorization Code + PKCE). No proprietary SDK, no wallet logic.
User scans the QR code
Provica generates the verification request and shows a QR code or deep link for the swiyu wallet.
Wallet presents selectively
The wallet presents only the purpose-bound attributes – as an SD-JWT VC via OID4VP.
Verified claims returned
Provica verifies, minimizes and delivers the attributes as an OIDC ID token and via the userinfo endpoint.
Three integration forms, one platform
You get the result in whatever shape fits your application – from an account login to an age proof in the cart.
OIDC login
Integration form · Available in the beta
Best for
Portals that maintain an account.
At a glance
- A standard OIDC client (Authorization Code + PKCE)
- No proprietary SDK, no wallet logic in your portal
- A separate, non-correlatable subject per tenant
- Back-channel logout, without polling
- Recovery code when a new e-ID is issued
Check API
Integration form · Available in the beta
Best for
Applications that need no identity, just an answer.
At a glance
- Two REST calls – no OIDC redirect, no account
- Rules: age_over_16, age_over_18, age_over_65 and nationality
- Signed result token, redeemable exactly once
- Bound to aud, nonce and exp
- Two checks on the same person stay unlinkable
Age gate
Integration form · In preparation
Best for
Shops that need age verification without holding credentials.
At a glance
- Age requirement per product and per category
- Derived from the real cart, at every checkout path
- Only consumed after a successful payment
- Your shop holds an API key, never a client_secret
- No date of birth in the shop – you get a yes or a no
Open standards, integrated into what you already use
WordPress protects content (available in the beta), WooCommerce blocks orders (in preparation).

On the official Swiss e-ID ecosystem
Weeks of work saved
A custom swiyu integration costs weeks of implementation – plus ongoing operation. With Provica you're live in an afternoon.
For portals, shops and content
Government portal, online shop or content platform: login, anonymous checks and age verification all come from a single integration.
