Just for the “Bläserfestival” (Brass Festival) in Weil am Rhein, south Germany I built three of these devices. Not that staff at the Beer-Tent are not able to calculate, but some of the colleagues are not very often working at a Beer-Tent, deposit also have to be considered and customers turn to zombies at the current 36 degree Celsius, BarMate will support them.
Currently BarMate is a prototype and we will see if it really speed up calculating. So orders like: “2 beers, 1 Coke, 1 Weizen and by the way, I would like to bring back two empty bottles” should be easy to manage for BarMate.
If you are interested to have BarMate also at your event, just contact me.
