Automatic chocolate vending machine

This paper proposes the design of Automatic chocolate vending machine. The primary point of the thought is to dispatch new innovation application in the public eye. Vending machine that sales different type of products. Here we uses Radio frequency Identification (RFID) along with Arduino, to overcome the coin based vending machine which does not returned the balance amount if no change available. The customer can select the product before the RFID is read, after card is scanned the product can be collected at the chocolate collector. There are three units are present in the machine, the cashless payment provided by the RFID in the firstunit. In secondunit, Arduino UNO executed the programming section and Finally, the machine delivers the product and displays the information on the display. This paper made solution to the machine that do not returns the balance amount in a coin based vending machine.
