This project requires you to know the Raspberry PI or similar device inside and out.
Today my clients can pay 6 different rates depending on the line they are using. Today this amount is paid directly to the bus driver. To minimize the queues I would like a system that would perform the sale and issue a QRCode with a specific hash of one of the lines.
At the other end a raspberry pi would read the reading of the qr code and check if the line hash of the qr code is compatible with the line that is configured.
The line selection on raspberry could be using LCD display and two buttons or any simpler mode. For being cars the raspberry pi should work offline, only checking for some kind of compatible hash.
