Add qr-code/barcode reader app

[asokero]

https://apps.gnome.org/fi/Decoder/ would be nice, but most likely not available for Bookworm.

Zbarcam-gtk is available. It has some rough edges from the UX perspective, but it works.

Hey Antti, how can I start zbarcam for qr codes? I found the message in changlog.opinsys.fi and I want to test it. :-)
Best regards, Ralf

Hey, you can launch it from command line/terminal by zbarcam-gtk. The application is quite legacy and the package did not include desktop file so it is not in the menu. But I added it there so that it could be easily tested on different devices/cameras. This does not work on MS Surface.

Yes, I got it. Great!
Could it be possible to put a space between QR-Code and the url?
And could it be also possible to make the url easy clickable with the mouse?
