Wut? Why is CrazyGolem project owner all of a sudden?
Item database
How do you want to add the Qr code to the stickers and what's your plan to track the item we have ?
Well, the QR codes will be either printed together will the label when the person remotely prints the label, or the QR code can be printed separately from the label and placed on a pre-printed label. As per the db, I have no clue. Maybe some online parts database, or a custom made one.
