`terminal` directory contains the code running on the terminal. It is
based on a standard [buildroot](https://buildroot.org/) distribution.

+[`terminal/src/mt-apps`](./mt-apps.git), which contains the web server
powering the GUI of the terminal – a web browser. Among other things,
it informs the browser about physical events captured by the terminal
from the card reader and coffee machine buttons.
