Give physical documents a verifiable digital identity.
T-CODE places a machine-readable TDOC DataMatrix on any printed document — linking it to a verifiable digital record that anyone with an ANANKE LABS account can check. No trusting a phone call. Verification, not guesswork.
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.
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 TDOC DataMatrix — a compact, machine-readable stamp — directly onto printed documents. This stamp encodes a reference back to a verified digital record, enabling any authorized user to verify the document by scanning it.
What a TDOC DataMatrix looks like
The TDOC 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 T-CODE does for your organization
Key capabilities that bring verifiable trust to your printed documents.
Make any printed document verifiable
Stamp a TDOC DataMatrix on certificates, transcripts, letters, or any printed document. Anyone with an ANANKE LABS account can scan and verify instantly.
Detect fraud and tampering
If the physical document has been altered, the stamp will not match the original digital record. Verification fails clearly and immediately.
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.
Issue and stamp your documents
When you issue a document through ANANKE Trust with T-CODE enabled, the system generates a TDOC DataMatrix and embeds it onto the protected PDF. Use the web application or the Integration API.
Print and distribute
Print the stamped document and hand it to the recipient, mail it, or post it. The TDOC DataMatrix travels with the document — no separate QR card, no extra attachment.
Scan to verify
Anyone with the ANANKE Mobile app scans the TDOC DataMatrix. The app performs scan checks, connects to the ANANKE platform, and returns a full verification result in seconds.
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.
What a verifier sees after scanning
When someone scans a TDOC DataMatrix, the ANANKE Mobile app presents a clear, structured result — not raw data. The issuer controls what fields are visible to verifiers.
Scan a T-CODE to instantly verify any document.
Coming soon: T-Object
T-CODE currently supports TDOC — a DataMatrix stamp for printed documents. We are building T-Object, which extends the same verification model to physical products and non-document items.
Interested in T-Object for your use case? Contact us to discuss.
Who is T-CODE for?
Any organization that prints documents others need to trust.
Universities
Print diplomas and transcripts with TDOC DataMatrix stamps. Employers scan to verify instead of calling your registrar office.
