About the project
Cryptographic document trust, built for real-world workflows.
DocQRPro is a secure QR platform that digitally signs document data with an organization’s private key, compresses it into a compact code, and enables any third party to verify authenticity through a mobile app or browser.
It solves the expensive, slow, and risky problem of manual document verification: phone calls, emails, paper trails, and uncertainty across borders.
Benefit-focused features
Everything needed to issue and verify trusted documents.
REST API generator
Connect existing document systems using a simple API that works with any language or platform.
Mobile and browser verify
End users scan with the mobile validator or verify through a browser camera or upload flow.
PDC and EDC support
Use self-contained Primary Data Codes or Extended Data Codes for encrypted images and PDF attachments.
Revocable and chainable
Codes can be revoked or linked to newer secure codes for lifecycle control and operational flexibility.
Cloud or on-premise
Deploy in the cloud or keep private keys and critical signing infrastructure inside your environment.
How it works
From issuance to verification in four simple steps.
01
Upload or issue
Your DMS sends document data to the DocQRPro Generator API.
02
Generate QR
The organization’s private key signs and compresses the secure payload.
03
Embed and share
The encrypted QR is placed directly on the document at issuance.
04
Verify access
Anyone scans to confirm authenticity, data integrity, and tamper status.
Mobile application
Instant verification wherever the document travels.
The DocQRPro validator app gives teams, regulators, investors, auditors, and counterparties a fast scan-to-trust experience on Android and iOS-ready workflows.
- Scan document QR codes using the device camera
- Confirm signature, issuer, timestamp, and tamper status
- Validate serverless codes even when issuer systems are unavailable
- Open encrypted EDC attachments after successful verification
