Reads the Machine-Readable Zone (MRZ) on a passport or ID card and checksum-verifies the data, not just OCR guesswork.
The strip of text at the bottom of a passport or ID card isn't decorative, it's a standardised, checksum-protected data format called the Machine-Readable Zone (MRZ), the same one border control scanners read. This free tool parses that zone properly: document type, name, document number, nationality, date of birth, sex, and expiry date, and it checks the checksum-protected fields against their official verification digits, so you know when a result is confirmed correct rather than just an OCR best guess.
Take a clear, well-lit photo of the passport or ID page showing the two or three MRZ lines at the bottom.
The tool locates the MRZ, parses the encoded fields, and checks them against their built-in checksums.

Most "ID OCR" tools just run general text recognition over the whole document and hand back a wall of text. This tool specifically locates the MRZ lines, follows the ICAO 9303 standard used by every passport and machine-readable ID worldwide, and validates document number, date of birth, and expiry date against their official check digits. If an OCR misread would otherwise corrupt one of those fields, the tool detects the checksum mismatch and automatically tries the small set of well-known character confusions (like 0/O or 1/I) to recover the correct value, only accepting a fix if it actually restores a valid checksum.
Not every MRZ field carries a checksum, name and nationality, for instance, are not checksum-protected under the ICAO standard, so those are reported as read but not independently verified. If the name portion of the MRZ is too damaged or obscured by OCR errors to parse at all, the tool says so directly rather than presenting a guess as fact.

The Machine-Readable Zone is the standardised strip of text at the bottom of a passport or ID card, defined by the ICAO 9303 standard. It encodes the holder's name, document number, nationality, date of birth, sex, and expiry date, with several fields protected by check digits so scanners (and this tool) can verify the data wasn't misread.
The MRZ standard includes a check digit for the document number, date of birth, and expiry date. This tool recalculates that digit from the extracted value and compares it to the one printed in the MRZ. If they match, the field is confirmed correct, if they don't, the tool tells you rather than presenting an unverified guess as fact.
It specifically targets the MRZ, since that's the standardised, checksum-verifiable part of the document. This gives more reliable results than generic full-page OCR for the fields that matter most: document number, dates, and document type.
Passports (2-line MRZ) and machine-readable ID cards (3-line MRZ) that follow the ICAO 9303 standard, which covers the vast majority of passports and modern national ID cards worldwide.

No, this tool works without an account, for identity documents in particular, consider using a private or trusted device regardless of login status.
