We've built a mobile app to simplify interaction with the machine but you can also use any existing mobile ETH-wallet like Jaxx to buy something. Just scan QR-code the machine shows to you and press Send.
Also you can track the sales of the machine through web interface.
It would be great to share your code with a world!

However, if there's anyone who wants to contribute and tweak those apps making it worth sharing, please Telegram me: @martynovp
