Not every obligation needs a full passport. Sometimes you just need to prove a document is genuine and unaltered. Hash-anchor a Certificate of Conformity, CBAM record, battery, food or cosmetics document — and give auditors, customs and customers a tamper-proof, EU-hosted link. The file is hashed in your browser; it never leaves you.
Select a finished compliance document. It is SHA-256-hashed locally via the Web Crypto API — only the cryptographic fingerprint and your metadata are sent to us. The file itself stays on your machine.
We mint a permanent, EU-hosted public verification URL and a JSON-LD manifest, with the retention period the regulation requires — 15 years for an ESPR passport, 5 for a South African Certificate of Conformity.
Auditors, customs or customers open the URL and drop in their copy of the document. It re-hashes in their browser and confirms — instantly — whether it matches the anchored original. Tampering is obvious.
A single identity and one set of permanent verification URLs across the regulations your goods touch.
When you need to author full Digital Product Passports — AI document ingestion, supplier data collection, the regulation-aware compliance engine and EU Registry submission — the complete PassPer platform is one upgrade away. Start by verifying; grow into the passport.
Tell us which regulations your goods touch. We'll set you up to anchor and verify in minutes — and show you the upgrade path when you're ready for full passports.
