The design and operation of a cash machine
operating system are the subjects of this project. Meals
are mostly found in hotels, where transportation and
storage are stored, where retail machines serve food.
Accepting and assessing the value of a coin entered into a
trading machine is a crucial component of the machine.
When entering coins or tokens, a series of tests identify
the size, weight, electrical properties, and magnetic
properties of the coin, and any coin or token that fails
any of the tests is rejected. The value of a coin or token is
calculated based on the information provided. An
electromechanical system is used.
