Quickstart

Web demo

The web demo is at https://alsenet-labs.github.io/mrz-scanner/dist/index.html (nothing is uploaded)

Web demo from filesystem

The code is "same-origin friendly". That means it can be run in the browser from the filesystem (no web server required), with eg:

Use the prebuilt static version

git clone https://github.com/alsenet-labs/mrz-scanner
xdg-open mrz-scanner/dist/index.html

Rebuild and run the static version

git clone https://github.com/alsenet-labs/mrz-scanner
cd mrz-scanner
npm install
gulp dist
xdg-open dist/index.html

Web demo from web server

You can build the scripts, start a web server and open a browser, with eg:

git clone https://github.com/alsenet-labs/mrz-scanner
cd mrz-scanner
npm start

Command line tool

You can also scan documents from the command line using this repository or the latest published npm package. On success the result will be stored in a file suffixed by ".mrz.json" along the original image by default.

Using this repository

git clone https://github.com/alsenet-labs/mrz-scanner
cd mrz-scanner
npm install .
mrz2json [ -d|--dest-dir <directory> ] <png_or_jpg_or_tiff> [...]

Using the latest published npm package

npm install -g mrz-scanner
mrz2json [ -d|--dest-dir <directory> ] <jpg_or_png_or_tiff> [...]
