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.

Challenge

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.

Approach

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.

Teams, partners, and investors who protect trust

Whether you allocate capital, scale a channel, or issue documents at volume — if reputation and proof matter, we should talk.

Organizations & brands

Do you care about your company’s image — and refuse to let bad actors misuse your name or scam your customers? Want to win and keep trust with proof, not promises? LogiHash gives every asset a verifiable identity your customers can check in seconds.
