Basic Architecture

Components required:

Customer Frontend

The customer frontend is used to generate new tickets for the location, it will also show an overview of the current waiting time for new tickets. Can be used just like the "offline" ticket machines, we know from Finanzamt. As soon as a ticket is acquired it will show the estimated waiting time for the corresponding ticket.

Entry Conrol Frontend

The entry control frontend is used to check tickets and also create local tickets for customers w/o smart devices
