#22Every screen and printer will display/print colors differently. This is not a good idea.
Why wouldn't/couldn't this thing just disambiguate colorspace the same way it does rotation/position with predefined locator patterns?

#23How does this relate to the standard of the German ministry for Information Security (BSI) linked at the bottom of the README?
Note that isn't just one of many independent implementations as both the repository links to BSI and vice versa.

Microsoft comes up with a lot of neat little ideas. And also some bad ones. But mostly good ones.

#25I wonder if the 'Master'/'Slave' terminology is necessary here? Aside from being problematic, does it really describe the setup more than 'Primary'/'Secondary'?

#26Demo ( https://jabcode.org/create/ ) worked on the first example I tried, then I tried using advanced settings and it threw an "Error Something went wrong" every time. This was in Chrome.
With Advanced Settings you control the format and capacity of the code, so if you specify too many characters or too high of an error correction level it will fail (with that rather unhelpful error). Try increasing the version (which adds more pixels in the X or Y direction), or adding a few slave blocks.
(The above is based on my quick exploration with it on Safari, YMMV)

#27Is it just me or is that uglier than a QR code?

#28> master symbol and slave symbol nooo
Laughed hard

Without the advanced settings, it seems to automatically grow the code as needed. You need to manually add "slave" boxes though (to the right of the sliders). The interface is nonintuitive.

#30People print codes on glossy papers or try to scan them in various light conditions. This is not alternative for outdoor placement.
All barcodes can be printed on glossy papers, so that's not a unique challenge. Various light conditions aren't terribly difficult to account for, especially when known colors are involved (as they are here).
