Automatic Groceries dispensing system is a concept tried earlier but was never implemented because of the limitations in technology. The concept involves automatically dispensing the groceries like Rice, Wheat, Sugar etc according to the customers card type. In India there are different types of ration cards for different class of people.
Like the Yellow card for poor which allots them a certain amount of groceries like Rice, Sugar etc.
We can design a system which when entered the card number or swiped (RFID cards) will dispense the quantity of groceries allocated for that card every month. The quantity to be dispensed is maintained by a database or central monitoring station to which all the dispensing machines are connected. The concept involves reading the card number from the card and some accurate control of the valves using a microconroller so that exact quantity of groceries can be dispensed. This system helps in avoiding the delay caused in weighing the right quantity and also prevents the grocery store dispenser from cheating in quantity and quality.
