Telementry refers to the transmission of data by wireless technology from vending machine to base for recording and analysis. Using award winning technology (reddot design winner 2009) National Vending provides a service over and above the old SMS technology when machines run low. Our service provides accurate sales data by product variety, daily weekly and monthly. Our machines communicate on a network and tell us daily sales trends i.e what products we need to bring to refill the machine and error codes if any for example if power to the machine is disconnected. We even know if the temperature of the drinks at any particular point in time. All this without connection to an external telephone line!
