I think it makes much more sense to have the decoder server-side.
There are two reasons for it:
1. *one* code base!
I can tell you just how bad a lot of the QR decoder software running on
smartphones are -- because I have tried them.
2. if the decode doesn't work, you have the picture server side, and you
can perhaps improve the software and collect it as "a hard to decode
picture" and use it as a regression test.
This is similar to the reason Hot Line memos were always sent in the
language of the originator: avoid information loss due to translation.
