After some time of inactivity this project is now back to life! This is the one and original ZINT barcode generator, the reference in open source barcodes.
ZINT is licensed under the terms of the GPL v3. Only the contained backend (aka ZINT shared library) is licensed under BSD 3.
They don't encode QR Codes with ISO 8859 1 encoding, meaning that non american letters are encoded wrong a lot of the time. Something which should be fixed.
