This is a device which makes it possible to handle simplified accounting of coffee with a coded key. The apparatus consists of a single electro-

nic card on which are mounted the power supply unit, the microprocessor and related peripherals, the display and the components for the

management of inputs and outputs. A membrane keypad with 4 built-in keys makes it possible to use the various resources. The information

is shown on a 5-digit display. A TH type cover is included to contain the apparatus. The system is automatically power-supplied (230Vca ,

115Vca 50/60Hz). The serial interface is compatible with the and doses and along with the normal microprocessor

doses enabled for the serial transmission interface. A non-volatile memory in the card is able to store the required data, even in the event of

a power outage.
