payoutd controls the hardware and feeds events into redis queues where other tools may pick them up.
* Payoutd: https://github.com/sixtyeight/Payout
Changeomatic listens to events in those redis queues and allows users to change banknotes into coins.
* Maintenance Mode Application: https://github.com/phaer/kassomat-scripts
The protocol is documented in the [https://github.com/metalab-kassomat/kassomat-payout/blob/master/docs/overview.md payoutd repository]. People who are interested in implementing a more advanced POS system are very welcome to do so! :)
* Changeomatic: https://github.com/sixtyeight/changeomatic
There is now an [https://github.com/metalab-kassomat umbrella organization] on github which contains all the sub-projects listed below.
 
== Development ==
In case you don't have the actual hardware available you can use the Payoutd/Cash hardware Simulator instead: https://github.com/hettipeti/PayoutSimulator


The https://github.com/hettipeti/PayoutSimulator/tree/master/PayoutSim_v3/PayoutSimulator folder contains the latest version.
'''''Please note:''' From 6/2021 on the manufacturer of Smart Hopper (coin unit) and NV200 (banknotes) will no longer provide new currency or firmware updates. No spare parts, too.'' [https://metalab.at/wiki/Datei:Innovative_Technology_Ltd_-_Obsolete_Products_Notification.pdf cf. PDF]


== Status ==
== Kassomat/VM ==


payoutd controls the hardware and feeds events into redis queues where other tools may pick them up.
Instead of installing a lot of packages and requirements you could opt to use [https://www.virtualbox.org VirtualBox] and [https://www.vagrantup.com Vagrant]. The [https://github.com/metalab-kassomat/kassomat-vm kassomat-vm] repository contains all the necessary files to get a fully provisioned virtual machine (it is even possible to plug the actual hardware into your host and use it from inside the vm).
Changeomatic listens to events in those redis queues and allows users to change banknotes into coins.
The protocol is documented in the [https://github.com/sixtyeight/Payout/blob/master/docs/overview.md payoutd repository]. People who are interested in implementing a more advanced POS system are very welcome to do so! :)
