Is there any apps can dispaly a qrcode in share page?

I used nc in my classroom, I can share my file to all my students, instead send them the share url, I can open the url in a ppt file, and with a qrcode, my students can using mobile phones to scan it.

So is there any features or apps can complete this function?


There was an app for OC 8.1:

I don’t know how much effort it is to port this app to a current version. You might look into the forks, they have implemented some changes.
