In recent days I’m reading a lot about 2D barcodes (e.g. QR codes and DataMatrix). A list with many of them can be found here.

I personally find the most wide-spread and wide-supported type, QR codes (especially version 2 and higher), quite ugly. And while some of open-source alternatives (like public domain Aztec codes and MaxiCodes) are prettier than common QR codes, they are no match to some proprietary and patented solutions: namely Spotify codes, App Clip Codes, HCCBs, Messenger codes, ShotCodes and Boo-Rs.

Is there a Free barcode standard that looks just as nice?
