That code idea will never happen . They wouldn't be able to charge 500 bucks a year for access.
Yes it will probably never happen, but they could charge for it.
In fact it would be real simple as all it would have to do is access the database at the servicematters.com website.
As it is now you have to manually go to servicematters.com, finding the page to search for tech sheets and then manually entering the model number. Then click on the link for the .pdf to view the tech sheet or service manual.
All the above steps could be built into the QR code. Scan the code and auto download the info. Of coarse first you login with your servicematters.com password that you paid $500.00 for.
Scared they might be able fix it themselves? LOL
That or scared of a law suit if someone got hurt trying to repair it themselves, I don't really know...
