Scan-to-verify for printed documents.

ANANKE T-CODE stamps a T-DOC DataMatrix onto printed documents and records, linking them to a verifiable digital record on ANANKE's trust layer. Approved verifier organizations scan with the ANANKE Mobile app to confirm authenticity, integrity, and lifecycle status.

The problem we solve

Printed documents live in the real world — handed from person to person, photocopied, emailed as images. Once a document leaves your hands, there is no standard way to confirm it is genuine.

Countless
Printed credentials with no way to verify authenticity
Costly
Fraud from altered transcripts, fake certificates, forged letters
Slow
Phone-based verification: days or weeks, with no guarantee
Zero
Standard way to prove a physical document is unaltered

T-CODE bridges the physical and digital worlds. A small stamp on the page becomes the key to instant, cryptographic verification.

What is T-CODE?

T-CODE embeds a T-DOC DataMatrix — a compact, machine-readable stamp — directly onto printed documents. This stamp encodes a reference back to a verified digital record, enabling approved verifier organizations with an ANANKE account to verify the document by scanning it.

Physical + Digital
T-CODE bridges the physical and digital world — a printed DataMatrix that links back to a cryptographic proof.
Offline payload check
The mobile app can validate the electronic signature on the fixed T-DOC payload offline. A platform connection is required for the rich verification result and current lifecycle status.
Protected evidence
Online verification checks protected evidence and, where authorized, enables digital-twin comparison. It does not by itself prove every physical element is original.

What a T-DOC DataMatrix looks like

The T-DOC DataMatrix is a compact, high-density barcode stamped directly onto the printed document. It carries the references needed for verification and fast scan checks.

What it encodes
Issuer and document references with verification metadata
Size
Small enough to fit in a document footer or margin without disrupting the layout
Scan method
ANANKE Mobile app — built-in scanner decodes and triggers verification automatically
Offline decoding
The mobile app can run quick local checks and then connect for full status

What T-CODE does for your organization

Key capabilities that bring verifiable trust to your printed documents.

Make any printed document verifiable

Stamp a T-DOC DataMatrix on certificates, transcripts, letters, or any printed document. Approved verifier organizations scan with the ANANKE Mobile app and receive a structured verification result.

Detect fraud and tampering

Online verification checks protected evidence and can provide a digital-twin comparison. Changes outside the protected scope or a copied marker require that comparison and verifier judgment.

Access the digital twin

After scanning, verifiers can view the protected digital version of the document — a sealed copy of the original PDF. Compare the physical document to the digital twin side by side.

Track lifecycle in real time

Revoked a certificate? Suspended a license? Scanning the T-CODE stamp always reflects the current status — even if the physical copy was printed months ago.

Issue at institutional scale

Stamp single documents through the web application, or process thousands at once via bulk upload. The T-CODE process runs alongside ANANKE Trust issuance.

Build a defensible audit trail

Every stamp creation, scan, and status change is recorded. Full accountability for compliance and dispute resolution.

How it works

From stamping to scanning — the complete T-CODE workflow.

01

Issue and stamp your documents

When you issue a document through ANANKE Trust with T-CODE enabled, the system generates a T-DOC DataMatrix and embeds it onto the protected PDF. Use the web application or the Integration API.

02

Print and distribute

Print the stamped document and hand it to the recipient, mail it, or post it. The T-DOC DataMatrix travels with the document — no separate QR card, no extra attachment.

03

Scan to verify

An authorized verifier with the ANANKE Mobile app scans the T-DOC DataMatrix. The app performs scan checks, connects to the ANANKE platform, and returns a structured verification result in seconds.

04

View the digital twin

After verification, the mobile app gives access to the digital twin — the protected, sealed version of the original document. Verifiers can compare the physical copy to the original side by side.

The digital twin: bridging physical and digital

When a T-CODE stamp is scanned, the verifier does not just get a 'valid' or 'invalid' answer. They get access to the digital twin — a sealed, protected version of the original document stored securely in ANANKE infrastructure.

Compare the physical document to the original digital version — detect even subtle alterations
The digital twin is the exact PDF the issuer protected at issuance, stored in encrypted, organization-isolated infrastructure
Access is time-limited and controlled — verifiers receive a temporary viewing window

What a verifier sees after scanning

When someone scans a T-DOC DataMatrix, the ANANKE Mobile app presents a clear, structured result — not raw data. The issuer controls what fields are visible to verifiers.

Verdict
Authentic and valid, or not — a clear, color-coded status at the top of the screen
Document details
Name, type, lifecycle status (active / suspended / revoked / replaced), issuance date, and expiration if applicable
Issuer identity
The verified organization that issued the document — legal name, country, sector, and verification level
Approved metadata
Only the fields the issuer chose to share with verifiers — full control over what is disclosed
Digital twin access
View the sealed, protected PDF of the original document — for side-by-side comparison with the physical copy
Lifecycle history
When the document was issued, and any status changes since — with reasons if provided

Roadmap

Coming soon: T-Object

T-CODE currently supports T-DOC — a DataMatrix stamp for printed documents. We are building T-Object, which extends the same verification model to physical products and non-document items.

Verify physical products, packages, equipment, or assets — not just documents
Same scan-and-verify workflow through the ANANKE Mobile app
Designed to bring the same scan-and-verify workflow to physical objects and assets — full specifications under development
T-Object is on our roadmap and under active product design

Interested in T-Object for your use case? Contact us to discuss.

Security and data handling

T-CODE is built for organizations that handle sensitive printed documents. Here is how we protect your data:

The T-DOC DataMatrix encodes a reference — not the document content itself
Only minimal verification references are shared externally — no personal data
Protected PDFs (digital twins) are stored in encrypted, organization-isolated infrastructure
Integrity evidence is computed using keys managed outside the product database — never in application code
Digital twin access is time-limited: verifiers receive a temporary viewing window that expires automatically
Full audit trail for every stamp and scan — accountability without exposing document content

T-CODE FAQs

No. T-CODE uses a T-DOC DataMatrix — a high-density 2D barcode format that carries compact verification data, not just a URL.

ANANKE Trust handles the digital lifecycle: issuance, protection, verification, and status management. T-CODE adds a physical layer — embedding a T-DOC DataMatrix stamp on printed documents so they can be scanned and verified in the real world.

The digital twin is a sealed, protected copy of the original document, stored securely in ANANKE infrastructure. When a verifier scans a T-DOC DataMatrix, they can access the digital twin to compare the physical document against the original.

Approved verifier organizations with an ANANKE account. The issuer controls what information verifiers see. Verification is authenticated — not public or anonymous.

Scanning the T-DOC DataMatrix always returns the current status. If the document was revoked, suspended, replaced, or reactivated after printing, the new status appears immediately upon scanning.

The T-DOC DataMatrix stores compact verification references and metadata. It does not contain document content or personal data.

T-Object is a planned extension of T-CODE for physical products and non-document items, using the same scan-and-verify model. It is on our roadmap.

The DataMatrix is designed to survive standard printing and photocopying. However, since verification confirms the digital record — not the physical copy — the integrity of the underlying document is what matters.
