This paper discusses about the Using RFID Based Vending Machine to Distribute Milk. The processing plant the milk is distributed to warehouses in different localities inside the city from where it is supplied to the milk dealers of the city. The present situation of the milk distribution system must be changed because of the many issues like peoples need to be stand in the queue, i.e. very time consuming and makes parking issue near milk dairy. Also for distribution of Milk and collecting the money Human involvement is needed. So we propose a system in which the milk vending system cards are to be placed on the RFID reader for authentication and the required milk will be dispensed condition to balance available with customer’s credit and GSM will also provide an SMS about remaining balance in account.
