Scanning the QR code on the certificate or badge opens the certificate directly. Without one, enter the full 17-character VIN from under the windscreen; you get the car's newest certificate.

Data and security

  • Encrypted storage

    Certificates are stored in a managed Postgres database hosted in Tokyo, encrypted at rest and encrypted in transit.

  • Masked VIN

    The public page shows only the last eight characters of the VIN. Never the full VIN, internal notes or raw measurement logs.

  • Access control

    Row-level security restricts database access. The public interface can read only published certificates.

  • Private files

    Raw measurement files are kept in a private bucket that only we can access.

  • Random IDs

    Certificate IDs are randomly generated and cannot be guessed in sequence.
