Mat-O-Id app
Mat-O-Id is Money application that is open source under the GPL-3.0-or-later license. You and your colleagues have a cash register for beverages in office or club ?Tired of paying with coins ? Why don't use cheap RFID-Tags
All you need is a cheap tablet that can do USB-OTG, a card-reader and some tokens
Looks good on tablets bigger or equal 7"
(Sorry didn't optimize it for smaller screens, when I wrote it long time ago)
The first token you read in will become the Matmin-Token, that can change the price
and shows the status of the cash register
