Biometric
Identity credentials & ID documents
A portrait bound to the seal lets an officer match the holder offline — for national ID, access badges and border control. No lookup, no leaked biometric database.
Use cases
One engine for every document worth trusting
Anywhere authenticity, integrity and holder-binding must be checkable in the field, BioSeal fits — from a national ID to a printed shipping label.
Because a BioSeal is self-contained and scheme-agnostic, the same technology secures wildly different documents. The data and manifest change; the trust guarantees do not.
Education
Diplomas & academic certificates
Verify the issuing institution and the integrity of every field without ever contacting the university — a paper diploma with cryptographic weight.
Health
Health passes & medical certificates
Offline, privacy-preserving verification of a certificate's authenticity, with no health data held in a central system.
Products
Product authentication & anti-counterfeiting
Tamper-evident product tags that prove origin at the point of sale or inspection — the foundation for digital product passports under ISO 22376.
Travel
Visas & travel documents
The original home of the Visible Digital Seal: compact, signed travel credentials a border officer can check on the spot, offline.
Government
Permits, licenses & registration
Driving licenses, professional permits and vehicle registration documents that a field inspector can verify without connectivity.
Cybersecurity
Secure URLs — anti-quishing
A signed QR code lets a scanner confirm a destination is authentic before opening it, so a swapped sticker or an altered link is caught before any page loads.
Business
Invoices, shipping labels & documents
Give any business document a verifiable proof of origin and integrity that survives printing and travels with the paper.
Spotlight
Stopping “quishing” before a link loads
Quishing — QR-code phishing — swaps a legitimate code for a malicious one, bypassing email filters because the link is hidden in an image. With a BioSeal, the destination is cryptographically signed: an attacker cannot forge a valid signature or alter the URL without breaking verification, so a compliant reader rejects the fake before the browser ever opens it.
- The seal proves the link came from the real issuer.
- Any change to the URL breaks the signature.
- The check works offline, on the device.
