Write a note on vending machines.
Vending machines are coin operated machines and help in selling products like milk, soft drinks, hot beverages, platform tickets, etc. The latest development under this concept is Automated Teller Machines (ATM) in the banking sector. This machine has made it possible to withdraw money any time without visiting any bank. Vending machines are especially useful for selling prepacked goods at a low price, having high turnover and are of uniform in size and weight.
The main limitation of these machines is that the installation cost of these machines is very high. The expenditure on regular maintenance and repair on them is also very high. Another limitation of this system is that the customers can neither see the product before buying nor return unwanted goods.
