Is there any error handling if the scratch off is a bit too vigerous? How can the note be validated with revealing the code?
How can I get some made?
I'd be interested in these for something I have coming up. Or just generally for my meetup.

There are a lot of tradeoffs and it should be used in a trusted environment or as a tip/donation method. You have to trust the issuer, and the mint. Maybe there will be a trusted issuer over time with good security features. I will release the Template for the bills, when I get them perfect.
