Any thought on how to transfer Compact SeedQR to the steel plate? I'm asking because master SEED can be presented now in both SeedQR forms on the screen of Passport 2  which is device to manage my bitcoin stash. I thought about mapping the transparent film with the relevant image and use it for the further transfer to the metal plate. But maybe you have a better view on this matter.
I wonder, does the new version of Passport allows you to magnify each area of the generated QR code? That would make it rather easy for you to zoom a certain section of the QR code, grab a metal plate, a steel hammer and a punch tool and just start hitting that steel plate. You can see that process in action here[1]. Could you please confirm if Passport has this functionality? (at first sight I would say that it doesn't, but I can't actually test it)

As an additional tip, in order to improve the readability of steel plates I would also follow these[2] recommendations as some users report having problems scanning from them.
