BIG Register — Digital credentials for healthcare professionals
The BIG register is the Dutch registration system for healthcare professionals — nurses, doctors, physiotherapists and others must be registered before they can practice. Until now, this registration was issued on paper or as a PDF, requiring manual verification by employers and institutions.
With Credenco, BIG registrations become cryptographically signed digital documents carried in a personal wallet. Employers can verify registrations instantly, without accessing sensitive data or contacting the registry.
The solution
Credenco partners with CIBG to issue BIG registrations as Verifiable Credentials via QR codes in a secure portal. Healthcare professionals scan once with their wallet app and receive their credential immediately. No postal delivery. No manual verification. No paper.
