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.

1. GENERAL DESCRIPTION
The requirement of the automated stock maintenance and
billing system rose from ration shops. Goods were delivered
to various ration shops in a particular quantity but after a
few surveys it was concluded that the quantity delivered to
the customers were quantitively less. The same amounts of
goods were not delivered to the customers as of the retailers
either sold a part illegally or supplied it to other private
retailers at higher costs. Quiet a mass of goods were forged
or sold illegally by the retailers.
The same goods that are purposed to be sold at
governmental public distribution system were sold to
customers by private retailers at higher costs. This problem
occurrence was due to illegal supply of goods from
governmental public distribution system to the private
retailer. This not only caused loss of economy to the
government but also caused inconvenience to the public as
they were not supplied with the required amount of goods.
To keep a check over this issue this stock maintenance and
billing system can prove to be a useful remedy. In this
system implementation of NFC tag and reader is done. Also
the load cells are provided to measure the quantity received
by ration centers and the quantity delivered to customers.
This system also bears the capability of intimating the
customers on arrival of new stock in the stores. The
information will be provided to various customers via usage
of GSM. The GSM will send text message to all its
registered customers as soon as the new stock arrives.
2. LITERATURE REVIEW
Near-field Communication (NFC) is characterized as a short
range radio communication technology with a lot of
potential, especially when applied to mobile handset. In
order to make the establishment of these contactless
connection easier, this popular communication technology
was created. NFC gateway protocol can be used for network
driven services [1] and a secure authentication process to
achieve a NFC m- payment system.
NFC can also be used in industries were companies
producing consumer products have begun working on ways
to control their products over the IP (internet protocol).
Multinational electronics firms are marking a fair share of
their lines using technologies like the RFID, NFC, etc a
front end to the IP networks where every piece of equipment
integrated is to be controlled by a central unit.
IP based systems are supposed to be simpler to be accessed
and easier to manipulate, with the only necessity being,
close proximity to a direct internet connection. With this in
mind IP Ac Box was developed [2] which allows industrial
automation systems to be accessed and controlled through a
direct internet connection right out of the box even in
dynamic IP configurations.
The Near Field Communication (NFC) technology provides
a good opportunity to support the automated execution of
several education related processes. Recently a new
challenge is identified at the Budapest University of
Technology and Economics. As most of the lecture notes
had become available in electronic format the students
especially the inexperienced freshman ones did not attend to](https://image.slidesharecdn.com/nfcbasedstockmaintainanceandbillingsystemwithautoalerttocustomers-140820042213-phpapp02/85/Nfc-based-stock-maintainance-and-billing-system-with-auto-alert-to-customers-1-320.jpg)

the lectures significantly decreasing the rate of successful
exams.
This drove to the decision to elaborate an accurate and
reliable information system for monitoring the student's
attendance at the lectures. Thus Benyo and his team [3]
developed a novel, NFC technology based business use case
of student attendance monitoring. In order to meet the
requirements of the use they implemented a highly
autonomous distributed environment assembled by NFC
enabled embedded devices, so-called contactless terminals
and a scalable backoffice. Beside the opportunity of
contactless card based student identification the terminals
support biometric identification by fingerprint reading.
These features enable the implementation of flexible and
secure identification scenarios. The attendance monitoring
use case has been tested in a pilot project involving about 30
access terminals and more than 1000 students.
Near Field Communication (NFC) is a promising new
communication technology that, among other things, allows
mobile phones to emulate smart cards such as the travel
cards used in public transportation. Bringing the travel card
into mobile phone creates numerous benefits for both end
users and service providers, which is why mobile ticketing
with NFC technology has been considered a promising
service. However, despite optimistic predictions, NFC
technology and mobile ticketing services based on it, has yet
to take off. While technical problems have played a part in
this delay early on, the most significant reasons can be
found in the challenging business models needed to realize
NFC services. Thus NFC based mobile ticketing business
model [4] is evaluated using a theoretical framework called
the STOF model.
Want, R, in his paper entitled near field communication [5]
had given a detailed note about near field communication.
He proposed that for many years, pervasive computing
research has explored the potential benefits of creating a
connection between the virtual world of the Internet, and the
physical world we live in. The Near Field Communication
(NFC) standard might, at last, be the technology that makes
this vision-sometimes referred to as the Internet of things-a
ubiquitous reality.
3. PROPOSED SYSTEM
The objective of this project is to automate the ration shop
using NFC, Load Cell and GSM module so that the
customers can be made aware of the availability of goods as
well as arrival of the new stocks in the ration shop. This
system is also convenient for the retailers to keep an account
on the availability of goods. This system also bears the
capability of intimating the customers on arrival of new
stock in the stores. The information will be provided to
various customers via usage of GSM. The GSM will send
text message to all its registered customers as soon as the
new stock arrives. The load cells are implemented for
accurate results. The items purchased by the retailer and
sold by them are put into account which can be made for
stock maintenance.
In this proposed system, stock and supply identification,
calculation and the intimation of stock arrival to the
customers are made automatic using NFC. In this system,
each card holding customers of the belonging to particular
areas’ ration shop are provided with smart NFC card. When
new stocks for ex: (sugar) arrive at the shop for the month,
then using a GSM modem in the shop, a message is sent to
all the customers’ mobile numbers. The card holder can buy
it by using the NFC tag provided to them. Each item is also
provided with a NFC tag.
NFC reader in the shop reads the value, compares it with the
help of microcontroller and then provides them the items by
measuring their exact weight using a load cell. The card
holder cannot purchase that particular item again if their
limit has been crossed for that month. Also, the incoming
and sold out stocks in the shop is identified using IR
sensors. Once if all the items have been purchased by the
customer for the month, then they cannot again purchase
any items in the same month.
Also, a message is sent to the mobile number using GSM
modem in the shop that all the items which are eligible for
their card for the month has been purchased. By
implementing this method, forgeries can be restricted to a
great extent and proper supply for the needy and eligible
person will be provided. We developed the system with
different devices such as PIC microcontroller, a LCD
display, MAX 232, load cells, a NFC tag reader and NFC
tags provided to various goods respectively. After doing the
connection we have installed the NFC tags on the sample
goods. Now by using the NFC reader we will scan each
NFC tag provided with the respective goods. Each time
NFC tag reads a data LCD module will display the details of
the particular item. The NFC is used to read the available
and purchased items and correspondingly the load cell
provides the exact quantity of the particular item.
The data’s from NFC will be stored for future reference and
documentation of the amount of goods available and sold.
The microcontroller is programmed to control all this
activities. The GSM module is used to provide the details of
available stocks and commodities to the consumer.
The PIC Microcontroller is the heart of the system which
controls the entire process effectively. Microcontroller
manages and controls the functioning of IR sensor, NFC,
and GSM module.](https://image.slidesharecdn.com/nfcbasedstockmaintainanceandbillingsystemwithautoalerttocustomers-140820042213-phpapp02/85/Nfc-based-stock-maintainance-and-billing-system-with-auto-alert-to-customers-2-320.jpg)

6. CONCLUSIONS
From the results, we have determined that load cell
weighing technique is superior to the conventional
electronic weighing machine. The NFC system has an ace
over the RFID as it has a faster response with an enhanced
accuracy. The ease of usage also makes it more practical for
implementation. The system is convenient for the retailers to
keep an account on the availability of goods. The system
also proves worthy for the customers as they are awarded
about the goods available in the stock. The customers will
not need to queue up in ration shop for hours as the can
approach the centers only on intimation. Thus the proposed
simplifies the purchase and delivery of the items moreover it
is properly documented. Thus the entire process is
automated which saves the consumers precious time by
saving them from waiting in the queue for long time and
makes the consumer up-to-date about the availabity of items
in the ration shop.
FUTURE WORK
This automated system can be incorporated along with
RFID secured system to employ more precise record of the
incoming stock in the ration shop. When RFID is
implemented along with NFC this system will make ease of
communication between the consumer and the retailer or the
ration shop.

The main components of this system are PIC Microcontroller, Load cell, NFC Tag, IR Sensor and GSM modem. The IR sensor1 senses the arrival of the items and send a signal to the micro controller. The micro controller forecasts this information to the consumer by using GSM module as well as the item arrival is also entered in the stock. IR Sensor2 is used to know the items dispatched to the consumer when an item is delivered to the customer the same amount will be reduced from the stock. For measuring the weight of items available in stock and to know the weight of items dispatched the load cell is used. Load cell senses the weight of items and gives the information to the microcontroller for stock maintenance. NFC tag is provided to each customer in that particular area. There will be separate tag for each item. Once the items arrived in ration shop the message will be send to the consumer and he can purchase the particular item by using the particular tag. The NFC reader in the shop will sense the consumers NFC tag and provides the particular item to him. Consumer will have separate NFC tags for stock as well as for the items to be purchased. 4. NFC Near Field Communication (NFC) is a new short-range, standards-based wireless connectivity technology,that uses magnetic field induction to enable communication between electronic devices in close proximity. Based on RFID technology, NFC provides a medium for the identification protocols that validate secure data transfer. NFC enables users to perform intuitive, safe, contactless transactions, access digital content and connect electronic devices simply by touching or bringing devices into close proximity. Near field communication (NFC) is a set of standards for smart phones and similar devices to establish radio communication with each other by touching them together or bringing them into proximity, usually no more than a few inches. Present and anticipated applications include contactless transactions, data exchange, and simplified setup of more complex communications such as Wi-Fi. Communication is also possible between a NFC device and an unpowered NFC chip, called a "tag". NFC standards cover communications protocols and data exchange formats, and are based on existing radio-frequency identification (RFID) standards including ISO/IEC 14443 and FeliCa. The standards include ISO/IEC 18092 and those defined by the NFC Forum, which was founded in 2004 by Nokia, Philips Semiconductors (became NXP Semiconductors since 2006) and Sony, and now has more than 160 members. The Forum also promotes NFC and certifies device compliance and if it fits the criteria for being considered a personal area network. 5. RESULTS AND DISCUSSION In this paper an innovative way to automate the ration shop is proposed. We have used NFC reader instead of RFID which enhances a faster and accurate result than RFID. Moreover GSM modem is incorporated which facilitates the consumer by providing the availabity of the items without waiting in the queue for a long time. As an advantage, by using load cell and IR sensors accurate weight of the items in the stock as well as that supplied to the consumer is guaranteed. Moreover the forgeries in the ration shop can be reduced to minimal.
