Never heard of a qr steel plate.
You may get like border wallet option. They're a pretty cool idea.

Very cool
That a piece of plastic that goes over the steel to guide you stamping it? Buy from seed signer?
Yes!
You keep the plastic on until you're done punching.
Buy this german brand of puncher btw - I'd get the best one available if you can afford it (highest force/pressure model).
Double punch each hole.
When you're done, take the plastic off & scan (with patience).
I started to watch this the other day but didn't have time to complete
