There are already similar machines made in Korea that do exactly this with BCH. I hope to see them start getting deployed!
I don't think you'll get many of these little independent ramen/gyudon/etc. places to switch out their machines. A $35 raspi mod would be way more painless imo. USB port + phone wallet
These machines are much more prevalent in japan than in korea. The manufacturer is probably aimed at new restaurants that are trying to cut down on labor.
It's a great system. All you need is a cook or two and a bus boy/girl and your restaurant runs like a machine. It allows mom and pops to thrive as much as the big chains. Cash is king!
