Is simply taking the voidstate squad # the current way to do things, while you add players to your tournament in cryodex?
That, if people have a squad number, put it in and when you do the import it will get the squad for you. The implementation of a qr code was just too difficult for laptop webcams. They aren't designed to focus as efficiently as real cameras. Typing the number is in significantly faster than trying to get that **** thing to read your qr code.
