It’s easy to use: the screen on the coffee machine displays a custom QR code. When someone wants to buy a drink without touching the screen, they scan the code using their smartphone camera or QR code scanner and the drinks on offer are shown on their phone. Then they select a coffee speciality, place the corresponding cup under the spout and start the brewing process on their own phone - without downloading or installing an app and without touching the coffee machine screen. Melitta^® Remote Coffee^® is compatible with any up-to-date operating system and is available as a software update for fully automatic coffee machines from Melitta Professional with a telemetry module.
