Universal IoT Vending Machine Management Platform

With the advances of technology, vending machines have evolved from simple devices that sell individual products and provide simple services to complex devices where product and service offerings are tailored to each individual user. Following the increasing need to use a large amount of information in real-time (optimization of supply, timely updating of machines, monitoring the status of vending machines, etc), an increasing number of vending machines are connecting to the Internet and represent the IoT devices in the IoT ecosystem. In this paper, a solution for a universal IoT platform for managing vending machines is proposed. Emphasis is placed on the implementation of the control unit with an additional module for interaction with the users.
