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.

Interesting suggestion which didn't strike my head yesterday at the test of  the new version of Passport. Today, after reading it, I have tested Passport ad hoc  and can confirm that it doesn't allow to magnify areas of SeedQR.

Thus my plot is the following: I would cover display with transparent film, using the fibre-tip pen with permanent ink  map to this film  the relevant Compact SeedQR and then, after placing this film on the steel plate hammer it with a punch tool.

I would     reluctantly  use any electronic based mediator (like Web cam) at SeedQR transfer as In my view it might potentially pose a threat for Seed safety.
