The inside of the roll has an NFC chip in it. The NFC has information on color, amount of filament left, temperature settings etc.
I call it DRM because you can't edit it without a reverse engineered NFC key.
Another side to the DRM thing is that if you use inferior input material and the printer has a quality issue, customers are going to blame the printer and not the filament.

Value added DRM I guess
