Guides, tutorials, and best practices on passport data extraction, MRZ reading, ICAO 9303 validation, and KYC automation.
A guide to the US passport data page: what fields it carries, how the name is encoded in the MRZ, what the passport card is and why its MRZ is a different format, and what changes with the electronic passport.
How to cut international guest registration from minutes to seconds by reading the passport: what data to capture, how to integrate with your PMS, and how to design the flow so the front desk stays in control.
The criteria that separate a usable passport reading API from one that will cause problems: MRZ validation, failure behaviour, data retention, pricing model, and how to test each before you commit.
The three ICAO 9303 machine readable zone formats: how many lines each has, which documents use them, where the field positions differ, and how to detect the format automatically.
How to automatically verify whether a passport is valid, why many countries require six months of remaining validity, and how to implement the check using the MRZ expiry date.
The real reasons automated passport reading fails — glare on the laminate, a cropped MRZ, insufficient resolution — and how to fix each one at capture time.
How to build a customer identification file from a passport: what data to capture, how to leave auditable evidence of the reading, and what to automate without losing traceability.
Step-by-step integration of a passport data extraction API: the four image upload methods, handling every error code, and ready-to-use examples in JavaScript, Python and PHP.
The 7-3-1 MRZ check digit algorithm explained step by step, with the full arithmetic on a real passport, the blind spot nobody mentions, and implementations in JavaScript and Python.
A complete map of all 88 MRZ positions on a passport: what every character of both lines contains, how names are encoded, why the dates carry no century, and how to decode one by hand.
A complete guide to extracting data from passports of any country with OCR: what the MRZ is, how ICAO 9303 check digits work, and how to integrate it via API.
