Abstract: This paper suggest a novel automation scheme for stock and billing management in ration shops using NFC and load cell technologies. This system prevents from forgeries like, by selling the stocks belonging to one card holder to others; not providing the eligible card holders what they require. NFC Tags are provided to each customer for that particular area belonging to a shop in that area. Load cell is used to measure the correct quantity eligible for each card. The card holders will be intimated by a message using GSM technology about the arrival of every new stock in the shop every week for the whole month. Using this message, they can buy the items. Load cell is used to measure the correct weight of the items according to the card’s limit. They cannot buy more than this eligible limit using the card again in the same month. Stock management is done by using two IR sensors. If the stocks pass from IR 1 to IR 2 then it denotes the selling of items and if it passes from IR2 to IR 1, then it represents buying of stocks for the shop. This is also verified with the weight of the stocks when sold. Each item is given a NFC Tag for easy billing process.
