QR codes on cards would work as well, if I'm understanding what this project is. The floppy disk approach has some nostalgia maybe but seems quite fragile. I quickly learned to never let my kids handle CDs/DVDs (one of the worst physical media designs ever; they are totally unprotected) as they would quickly become damaged and unplayable. Floppy disks are at least sort of protected but the same idea applies.

I still have a large number of working CDs from when I, myself, was a kid. DVDs too but they were later and more durable.

I’ve always wondered what people are doing to them? Maybe I just got lucky. Maybe I was just careful with them. Maybe I don’t remember the ones that failed.

I don’t think kids are less careful now, although being screamed at for making the CD or record skip was probably a deterrent.

		Some people really get the idea of only handling it around the edges. Lots of other people just handle them however they want and have no problems touching the media anywhere. Especially kids, which often don't have the cleanest hands at any given moment. Lots of kids will handle them however they want. They'll pick them up with greasy, sticky hands right on the media section. They won't necessarily care about ensuring they're properly in the drive tray. They'll jam all kinds of things into the drive slots. They'll drop them on the floor and step on them, toss them in a toy box when told to clean their room, etc. Obviously not all kids will be this way, but many will.
