What is Donic-Schildkröt's "QRC system"?

As I know from official page,

With the QRC (Quick Rubber Change) rubbers you can simply stick on the new or higher-class coverings. The unique Schildkröt QRC system is designed to replace and upgrade rubber and sponge within seconds. Simply pull the old one off and stick on the new one.

But I can’t find any video or (more) detailed instruction about how to change one rubber to another. Also I found only three rubbers supporting QRC – "QRC-Rubber Liga/Energy/Champ" and that’s all.
So, my questions are:

1. Am I need a glue to install new rubber?
2. What rubbers I can install to the bat with QRC?
3. How exactly to do this?

P.s.: For context, I’m using Carbotec 900 now.
