= Project: Pad-based salespoint

== Intro: 
At my relief organisation there's a frige. Everybody is able to take out drinks an to pay using cash.
This happends on a "trust" basis: Everybody puts the right number of coins in a cup nearby  
 - OR - marks, that's he's going to pay later one. 

== Idea / Problem:
We don't know how many drinks are sold. People have outstanding credits for quite a while.
This makes buying drinks cumbersome.
