Trust that travels with the asset
Verify authenticity in seconds — not with trust in a screenshot.
LogiHash binds encrypted metadata to a scannable T-Code so anyone can confirm integrity and origin using standard phones — without exposing secret keys.

Real T-Code — full verification flow
This uses the same deterministic demo payload as the Try intro video: real signatures, real decryption, and the same metadata you see in the API examples (John Doe / Contract). After the success screen, we switch to an ordinary QR on the same interface so you can compare outcomes.

Cryptographic verification
Signed structure and metadata checks, not just URL redirection.
Operationally practical
Mobile scan, API issuance, and web workflows aligned for real teams.
Built for scale
Designed for enterprise issuance volumes and partner ecosystems.
Why LogiHash exists
Organizations struggle to prove that a document, ID, label, or parcel is the same object that was issued — especially across channels and time.
The problem
PDFs can be copied, QR codes can be reprinted, and screenshots are not proof. Traditional QR often only redirects to a website with no cryptographic binding to the physical or digital object.
The LogiHash approach
Each asset gets a T-Code: a compact, signed representation tied to encrypted metadata. Verification confirms structure and signatures — so stakeholders see whether the code matches a genuine issuance, not just whether a link resolves.
Built for real-world programs
From compliance-heavy enterprises to high-volume logistics, LogiHash is designed to scale with your issuance workflows.
Identity & workforce credentials
Employee IDs, contractor badges, and training certificates with instant verification on mobile.
Contracts & invoices
Tamper-evident records for finance and legal teams — customers and auditors can validate what was issued.
Product authenticity
Protect brands and consumers: confirm that packaging and labels match genuine production data.
Logistics & parcels
Stronger chain-of-custody signals for shipments where a simple barcode is not enough.
Developer-friendly APIs
Issue T-Codes and verify them from your systems. Authentication uses your API key and client ID on each request.
