Use QR version 40 to increase amount of data per page #25

Closed arcanemachine closed 2 years ago

arcanemachine commented 2 years ago

The default QR code version used (version 10) results in the creation of many QR codes. This requires many more scans (and thus, much more effort) than the the highest-density QR code version 40. Furthermore, version 40 codes have higher information density over a given area that version 10, meaning their usage will save both time and paper.

Therefore, this simple pull request is to change the default QR code version from 10 to 40.

No, sorry. There is a command-line option.

Using my camera, code 10 or so was the highest I was able to reliably scan with a webcam. Can you let me know what results you get with a camera or scanner?

OTOH printing codes SMALLER (default QR "pixel" size is about 4 actual pixels I believe) worked a little more reliably, you can play with that as well.
