MRZ Toolkit
Professional tool for working with Machine Readable Zone. Full compliance with international travel document security standards.
Live MRZ Processing Engine
Automatic parsing, validation and ICAO 9303 compliance check
How MRZ Engine Works
Deterministic processing pipeline from structured input to ICAO 9303 compliant output with full checksum verification.
Input Data
Document fields are normalized and mapped to ICAO field positions before assembly.
MRZ Build
Lines are generated per TD1/TD3 format templates with proper padding and filler chars.
Check Digits
Modulo 10 with 7-3-1 weighting computed and verified across all required positions.
ICAO Rules
Structure, line lengths, allowed character set and field semantics validated against spec.
Output Ready
Valid MRZ string ready for copy, export and downstream OCR testing workflows.
Educational Purpose & Standards
This toolkit is designed exclusively for learning the ICAO Doc 9303 standard and testing optical character recognition (OCR) algorithms. The generator allows information security specialists and developers to verify the correctness of validators and checksums in a controlled environment.
Disclaimer
Random generation. All data created by the generator — names, document numbers, dates — is algorithmically generated from synthetic dictionaries. The tool has no connection to government databases. Any coincidence with real personal data is entirely coincidental and unintentional.
Prohibition of misuse. The site administration strongly condemns the use of this tool for creating forged documents or any other illegal activity. The user bears full individual responsibility for the use of generated data.
Technical nature. The tool is provided "as is" for diagnostic and research purposes. We do not store or process personal data uploaded to the OCR module.
Technical Protocol & Intended Use
The generator implements the ICAO Doc 9303 specification — the international standard for machine readable travel documents (MRTD). The tool is intended for OCR developers testing recognition algorithms and Security Researchers studying checksum validation mechanisms.
Local Processing. All data processing is performed exclusively on the client side. MRZ string generation, validation and OCR scanning occur in the browser without transmitting information to the server — this guarantees complete privacy of your test data.
