Show HN: QRaro, store binary data into QR Codes and retrieve it later
A Python module named "qraro" on GitHub encodes and decodes binary data into QR codes using `qrcode` and `zxing` libraries. Functions like `bin_to_qr` and `qr_to_bin` manage encoding and decoding. Instructions are available for installation and usage.
Read original articleThe GitHub repository features the Python module "qraro," designed to encode arbitrary binary data into QR codes and decode them back. It leverages the `qrcode` library for encoding and the `zxing` library for decoding. Key functions like `bin_to_qr` and `qr_to_bin` handle the encoding and decoding processes. The module incorporates error management and usage guidelines. To utilize this module, users can refer to the repository for instructions on installing necessary dependencies and employing the functions for encoding and decoding binary data into QR codes.

Does it have camera support? I added binary decoding feature to zbar a few years ago, zxing already had it and seemed to be in far better shape overall but zbar had builtin camera support which was necessary for my use case.
But then I quickly realized I probably have to design a metadata structure (e.g., how many total QRs, where is start, where is end, etc). I didn't continue after that :-P
Obviously this wouldn't scale in real world application, but it was a fun idea.
EDIT: And added gzip compression too
