Abstract: One or more drinks machines are used for preparing or providing drinks using a computers' network, and an adapter connected in between. The users can order drinks through a graphic interface and monitor the status of the drinks and of the machines. The orders can be managed using a queue and each user can be notified through the computer when the drink is ready or can he prepared. The adapter can he connected to an existing machine or provided with one. Another possibility is that the adapter would include wireless communication support. It may he possible that the adapter would also monitor the drink machine as well as sending commands for preparing ordered drinks.
