bin2qr

bin2qr is a command line utility which converts binary to a QR code. This QR code is not created according to the correct format, but purely from adding the bits with black and white pixels (1 and 0 respectively).

bin2qr can be pretty useful from time to time: I use it for Geocaching puzzles and some ARG's (Alternate Reality Games) have used this technique as well.

Installation

bin2qr can be installed using pip:

pip install bin2qr

Installing it using pip will also add the executable to your /usr/bin/ directory for global use.

Usage

usage: bin2qr.py [-h] [-qr_size QR_SIZE] [-square_size SQUARE_SIZE] [--text]
                 [--exact]
                 [data] filename
