| dc.description.abstract | Vending Machines are automated machines that dispense selling products such as Cola,
snacks, beverages, lottery tickets, and etc. It is vital to save time and reduce human energy.
These vending machines are developed in the way of Non IoT based and IoT based
methods. These Non IoT based machines are not smart and are not operated in real-time
data, which are functioned when giving cash or card and inputs (vending things) of the
machine. It is controlled by a micro-controller and distributed the given inputs. IoT- based
machines are computerized, which have cashless payment facilities, order facility before
going to the vending machine to order things, and can be identified the location of
machines by the customer. These IoT-based machines are assisted to suppliers to identify
the availability of the stocks. Simulation software and prototype are used to validate the
machines. In this review, it is found that most of the vending machines developed are
capable of operating without IoT technology, and nowadays, vending machine systems
are required to implement using IoT with machine learning, and artificial technologies to
satisfy the customer preferences. | en_US |
