Erm, few things here.
- I can't see really how to embed electronics capable to run an SPV
client into printed paper. I know that passive NFC tags can be printed on
paper, but not actual chips and/or power modules. So we are talking about a
completely different things here.
- even with paper notes printed proprietarily by some business the notes
itself still can have routes for independent blockchain-based verification,
and you won't need to trust anybody to test it. You will have to trust
security of the notes itself, but this is same as when you trust the phone
manufacturer when you're putting your bitcoin wallet on it.
So really I see only issues of technical security in here, and this is
the problem I'm seeking solutions for.
Best regards,
