Description:

Machine Readable Zone generator and checker for official travel documents sizes 1, 2, 3, MRVA and MRVB (Passports, Visas, national id cards and other travel documents)

Fields extraction example (valid for td1, td2, td3 and visas)
from mrz.checker.td1 import TD1CodeChecker, get_country

td1_check = TD1CodeChecker("IDLIEID98754015<<<<<<<<<<<<<<<\n"
                           "8205122M1906224LIE<<<<<<<<<<<6\n"

Installation:

From Pypi repo (It may not be the latest version):

pip install mrz

Cloning this repo (It may not work fine):

git clone https://github.com/davidix/mrz-lib.git
cd mrz
sudo python3 setup.py install

  • Name truncation detection
  • Error report, warnings report and full report in Checker.
  • Possibility that warnings compute as errors using compute_warnings keyword in Checker.
  • Possibility of disabling checks for country code, nationality and type of document, allowing to use 3-letter-codes not included in the countries dictionary and to use document_type codes without restrictions in Generator.
  • Added new checks for periods of time in Checker.
  • Visas support
  • Fields extraction in checker (name, surname, country, sex, etc) (version 0.5.0)
TODO:
  • Automatic name truncation in Generator
  • Possibility of disabling checks for country code, nationality, type of document and the others fields in Checker.
  • Add logging

IMPORTANT:

  • MRZ is a Python module to be used as library in other programs. So, its intended audience are developers. MRZ will never have a user interface nor will have CLI support. (Of course.. if someone wants, can do it) However, if someone is curious and wants to generate or check the mrz code of a passport or ID card, can modify any of the examples.
