Method and device for communicating with vending machine

A device for communicating with vending machine for selling goods and services (17) comprising a receiving part comprising interface modules, a logical part comprising logic and a transmitting part comprising a modem, characterized in that:

• The receiving part is built by a number of interface modules having the ability to work with different types and designs of vending machines (17) communicating with their payment systems (18) according to different standard protocols for communication between a vending machine and its payment systems, without any intervention in this communication;
• The logical part is a unified logic built of a peripheral logical unit (30) having the ability on basis of data detected from the communication between the vending machine (17) and its payment systems (18) to define different types of events such as events relating to the technical condition of the vending machine (17), event relating to the technical condition of its payment systems (18), events relating to the operating regime of the vending machine (17) and one-time events relating to the sales made by the vending machine (17), and to transmit these events to a central logic (40) having the ability to process all events and on basis thereof to define 3 types of states such as states relating to the technical condition of the vending machine (17), states relating to the technical condition of the payment systems (18) and states relating to the operating regime of the vending machine (17) and to transmit these states to a communication module (50) for transmission to a central location, e.g. server (407), of the current states and current values of sales and revenues in case the central logic (4) has generated a change of the state, in case a predefined period of time has expired since the last transmission, e.g. 5 minutes to 8 hours, preferably 2 hours, in case a request has been received from an external peripheral device (15) and in case a short text message (SMS) with a predetermined content has been received, the transmission of the current values of sales and revenues being performed in the cases where the current states are transmitted.
