Correct! One should watch for prying eyes and scanning cameras when bringing a printed nutsnote out. The most common use for these notes is probably gifts, maybe inside an envelope... but nothing stop anyone using it for paying for _coffee_ if merchants one day start accepting Ecash. I read in Cuba some already are, maybe @BTCLNAT can confirm?

Just another Ecash nutsnote

Looks good

I have a Stupid question:

I am not the most knowledgeable about ecash but if this was used in the wild, would the user need to secure the QR Code from prying eyes?

AKA: You would not want to pull your whole wad of ecash notes out in front of other people?

I am imagining a wallet type that lets one see the domination of the note with out showing the QR Code.  On your design you may want to print domination on the outside edge also to facilitate wallet design.
