Changeable content about kjua

A qr code encodes the content. So obviously for each content change, the QR code *has to" change. Everything else is not possible.

What you could do is use a link/URL shorter/website or so where you provide the information instead and just link there, then nothing has to change.

Everything is possible. You can look this site.
Me-qr.com

es and that service does exactly what I say. When you use an URL QR code it creates a QR with a link to https://me-qr.com/<somenumber>, so it essentially uses some kind of URL shortener.
Just scan the resulting QR code and you'll see that by yourself.

It's just not possible to do it otherwise, that's a fact you can deny, but it's just how QR codes work. See https://en.wikipedia.org/wiki/QR_code for more information.
