The authorities actually are trying to get us to use their app which does indeed generate a new code every time. However this is something I don't like because then I have any tracking of the actual app to worry about too. Especially because their lineage is pretty murky. I've gone to a lot of trouble to get facebook and google out of my life and this feels like a big step back. So I use the paper code exclusively.
Of course that also presents issues with people not owning smartphones, not knowing how to use them or having dead batteries as you mention already.
But what you describe would be better than the current setup if the operator is really transparent about how any personal info is used, yes.
All the covid tracking apps during the first wave were really privacy conscious (avoiding personal info, using open source etc) but the whole QR thing as introduced in Europe doesn't seem to have taken this into account at all. Of course that's because it's more personal in general but the whole open source thing has been dropped too. Only Switzerland seems to be doing that now.
