Make printed documents and PDFs instantly verifiable.
T-CODE embeds a secure verification code directly into your documents, whether printed on paper or shared as a PDF. Anyone with a smartphone can scan it and confirm the document is authentic, unchanged, and still valid.
Why printed documents need verification
Printed documents can be faked
Anyone with a color printer can reproduce a diploma, certificate, or official letter. There's no way to tell the original from the copy just by looking at it.
PDFs can be silently edited
PDF files can be modified without leaving obvious traces. Names, dates, grades, and signatures can all be altered after issuance.
Verification takes days, not minutes
To confirm a printed document is real, organizations typically call the issuer, send emails, or request apostilles, a process that can take weeks.
How T-CODE works, four steps
From issuance to verification in under a minute.
You issue the document as usual
Create your diploma, certificate, transcript, or official letter, using your existing tools and templates. Nothing changes in your document creation process.
T-CODE stamps a verification code onto it
A small, secure code (similar in appearance to a QR code, but using a more robust DataMatrix format) is placed on the document. You choose where it goes using our visual editor.
Print or share the document
Hand out the printed copy, email the PDF, or publish it. The verification code travels with the document, it's part of the document itself.
Anyone can verify by scanning
Open the ANANKE Mobile app, point at the code, and get an instant result: authentic or not. No account needed to verify, just the app and the document.
What verifiers see when they scan
A clear, instant result, no ambiguity, no waiting.
The document has been modified since issuance, the code does not match any known record, or the document has been revoked. The verifier is warned not to trust this document and to contact the issuing organization.
What a T-CODE stamp looks like
A compact DataMatrix code placed on your document using our visual editor.
Flexible positioning
Use our visual editor to drag and drop the T-CODE stamp anywhere on your document - top, bottom, corner, or alongside your organization's seal.
Compact and robust
DataMatrix codes are smaller than QR codes and more resistant to printing damage. They blend seamlessly into professional documents.
Instant verification
Anyone with the ANANKE Mobile app can scan the code and get an immediate verdict - no account, no login, just point and verify.
Two product lines under T-CODE
Documents today. Physical assets tomorrow.
T-DOC
For documents - diplomas, certificates, transcripts, official letters, contracts, and any paper or PDF that needs to be verifiable.
T-OBJECT
For physical assets and objects - tracking custody, verifying authenticity of products, and recording lifecycle events for tangible items.
Two verification modes
Different environments need different approaches.
Pointer Mode
RecommendedThe code on the document contains a compact reference. When scanned, it connects to ANANKE's verification service to retrieve the full result. Best for most use cases - works anywhere with internet connectivity.
Full Mode
In developmentThe code contains a self-contained verification payload. The scan can confirm basic authenticity even without an internet connection. Designed for environments where connectivity is limited or unreliable.
Built for real institutional workflows
Visual placement editor
Drag and drop to position the verification code on your document. Preview exactly how it will look before printing.
Template system
Create reusable templates for each document type. Set the code position once, then issue hundreds of documents consistently.
Bulk stamping
Process graduation batches or large issuance runs. Upload a batch of documents and get them all stamped in one operation.
Works with existing workflows
Generate PDFs from your student information system, HR software, or any tool. T-CODE stamps the verification code onto existing documents, no migration needed.
Mobile verification app
The ANANKE Mobile app is free for verifiers. Point it at any T-DOC code and get an instant, clear result with issuer details and status.
Always shows current status
If you revoke or replace a document after printing, the scan result updates immediately. Verifiers always see the latest state.
Frequently asked questions
Is a T-CODE the same as a QR code?
No. T-CODE uses a DataMatrix format, which is more compact and robust than QR codes. It can hold more data in a smaller space and is more resistant to printing damage. However, it looks similar, a small square pattern you scan with your phone.
Do verifiers need an account?
No. Anyone can download the free ANANKE Mobile app and scan a T-DOC code. No account, no login, no registration required for basic verification.
What if the printed document gets damaged?
DataMatrix codes are designed to be error-resistant. Even if part of the code is smudged or slightly damaged, the scan can still work. For severely damaged codes, verification can fall back to PDF upload mode.
Can I use T-CODE with documents I've already issued?
Yes. If you have the original PDF, you can stamp a T-CODE onto it retroactively. The verification proof is generated when the code is created, not when the document was originally produced.
How does this work with translated documents?
The T-CODE on the original links to the verified record. If you issue a translated version, it can carry its own T-CODE linked to the same verification chain, maintaining trust across language versions.
