Hi Diana
Space is at a premium here so we repackage our DVDs/Blu-rays into a thin case which is placed in a display sleeve. We used to keep the discs behind the desk, but we stopped that practice about 10 years ago. There has been no significant theft issue since we made this change
We use 1 RFID tag that is made specifically for discs and it is placed on the disc. This type of label cannot be used on double sided discs; in that case we use a regular RFID tag that is placed inside the description in the display case.
I don't know where we get the supplies, but l can find out if you are interested in going this route.
Our local recycling program accepts the discarded cases for recycling.
I have attached picture of the packaging we use. If you zoom in, you will be able to see the RFID tag on the disc.
