QR code not needed?

For complete context, or at least a reasonable facsimile…

As noted, it’s “Glowforge”, then a unique identifier. Right now they’re generated in batches so they’re sequential, but in the future they will be essentially serial numbers. This allows us to track the material from the factory all the way through to your Glowforge, so besides helping our logistics, in the future we can do things like update Proofgrade defaults (for example if we update the 3D engraving algorithm), or warn you if your material has been recalled.

We don’t encode the settings, since they may change.
