ABSTRACT
Barcodes are a technology for automatic identification which has
found application in many business sectors. As we know that bar codes have
many applications, they have been most used in segments of the retail
grocery as well as consumer goods industries. They use computers for
barcodes detection. A bar code has a self-contained message whose
information is encoded in the geometry of its printed bars and spaces.
Barcode is read, the patterns of light and dark contained in the bars
and spaces are translated into patterns of ones and zeros which the reading
computer interprets as numeric or alphanumeric data. In a simple bar code
system, her codes are read by passing a wand containing a light source and
a photo-diode across the code to be read.

1.3 Detail Description of Technology Used :
C# :
C# is a simple, modern, general-purpose, object-oriented programming
language developed by Microsoft within its .NET initiative led by Anders
Hejlsberg. This tutorial will teach you basic C# programming and will also
take you through various advanced concepts related to C# programming
language.
C# is pronounced as "C-Sharp". It is an object-oriented programming
language provided by Microsoft that runs on .Net Framework.
By the help of C# programming language, we can develop different types of
secured and robust applications:
o Window applications
o Web applications
o Distributed applications
o Web service applications
o Database applications etc.
ASP.Net:
ASP.NET is a unified web development model integrated with .NET
framework, designed to provide services to create dynamic web applications
and web services. It is built on the Common Language Runtime (CLR) of
the .NET framework and includes those benefits like multi-language
interoperability, type safety, garbage collection and inheritance. Mark
Anders and Scott Guthrie of Microsoft created the first version of ASP.NET
in 1992.
21. P a g e | 21
It was created to facilitate the development of distributed applications in
structured and object-oriented manner by separating the presentation and 5
content and hence write clean code. ASP.NET uses the code-behind model
to generate dynamic pages based on Model-View-Controller architecture.
They have some the major differences from ASP, an earlier version of
ASP.NET. The object model of ASP.NET has thus significantly improved
from ASP, which makes it fully backward compatible to ASP.
MySql :
MySQL, pronounced either ”My S-Q-L” or ”My Sequel,” is an open source
relational database management system.
It is based on the structure query language (SQL), which is used for adding,
removing, and modifying information in the database. Standard SQL
commands, such as ADD, DROP, INSERT, and UPDATE can be used with
MySQL.
A website that uses MySQL may include Web pages that access
information from a database. These pages are often referred to as “dynamic,”
meaning the content of each page is generated from a database as the page
loads. Websites that use dynamic Web pages are often referred to as
database-driven websites.
Many database-driven websites that use MySQL also use a Web scripting
language like ASP.net to access information from the database. MySQL
commands can be incorporated into the ASP.net code, allowing part or all
of a Web page to be generated from database information.
Because both MySQL and ASP.net are both open source (meaning they are
free to download and use), the ASP.net /MySQL combination has become a
popular choice for database-driven websites.
22. P a g e | 22
1.4 Purpose
In currently, most of the readers will be having provisions only for reading
from specified set of articles. The reader will not accept labels which are
specified in other languages or formats. Hence the existing system will not
have proper security as well as inability to read according to the wish of user
Barcodes have become a universal tool used by organizations in SCM since
the early 1970s and it is now a multi-billion-dollar business. However,
mounting pressure from a variety of areas is driving organizations to further
increase efficiency, which has led to the rise of RFID. Financial markets
demanding that companies use capital more efficiently and with the advent
of new technologies such as the Internet, consumers now have the ability to
compare prices around the globe, sparking a price war among retailers.
Business needs to be mindful of this trend as it will inevitably lead to tighter
profit margins.
23. P a g e | 23
1.5 Scope
The proposed 'Barcode Verification System includes all the factors of the
existing system but in more efficient way. Proposed system is developed in
C#.NET under MS SQL SERVER 2005 as back end and 2D barcode
algorithm is used for the implementation Only authorized users can enter in
to the system on entering the correct User name and Password. So
unauthorized users cannot access system.

Chapter 2
Literature Survey
2.1 Introduction
This literature review will satisfy the first objective as stated in section
which is to review literature on eBusiness with a view to identifying cases
in the use of barcode and radio frequency identification (RFID) technology
in supply chain management (SCM). The literature review will employ a
topical organization with previous research divided into segments that
represent categories or conceptual subsets relating to the thesis. The review
will consist of the following four distinct sections:
1. Barcodes
2. Radio Frequency Identification
3. Supply Chain Management
4. The Electronic Product Code (EPC)
25. P a g e | 25
Barcode recognition from an image, which can be used to insert the image
into a Barcode reader. The code can identify the image and retrieve the
portion of the file, which can include details about specific individuals and
organization logos, for example. The Barcode is located in this section.
Barcodes are of two types
i) 1D barcode
ii) 2D Barcode.
1D Barcode encodes the information or data between the parallel lines and
spaces between them, these parallel lines have different widths and different
spaces between them. A 1D barcode can only store the alphanumerical data
if more information is to be stored then the length of the barcode should be
increased.
When a barcode reader device scans the barcode, the reader uses a laser to
read those unique parallel lines and spaces. The barcode reader reads the
code from left to right when scanning it. After that, the barcode reader reads
the pattern of shaded lines on the black and white bar and converts the
encoded data into binary code.
After the information is extracted into a binary form the computer reads the
binary codes and the decoded information or data is displayed in the screen
of the computer screen. Barcodes are made up of 95 blocks out of those 95
blocks barcodes are written in 12 blocks. Three blocks are designated as a
left guard, center guard, and right guard among the 95 total blocks.
26. P a g e | 26
2.2 Barcode Standards
As with the history of barcodes, most works provide, to some degree,
background information regarding the development of barcode standards.
While most sources examine a number of standards, there is a common facet
among all works in that they discuss the importance of the UPC (Universal
Product Code) standard.
One work in particular by Brown24 provides a thorough insight into the
development of the UPC standard, including its formation and in depth
historical aspects. Regrettably, this book does not explore the use of
barcodes or their application to SCM, as it solely covers the UPC standard
for barcodes and related issues. Most works on barcodes include some
background information regarding the importance and development of the
UPC and the Uniform Code Council (UCC).
27. P a g e | 27
2.3 Barcode Applications
Barcode technology has been used for decades and during this time has
proved itself as a reliable performer when supporting SCM. Testament to
this is the versatility in which the technology can be adapted to suit specific
applications. There is a plethora of case studies which examine the role of
barcodes within a particular SCM scenario such as Auto Group hits high
notes with new inventory management system and RF cuts processing time
for Lexus car and parts deliveries.
The articles provide a snapshot of specific barcode implementations and, as
with most works of this time, both case studies provide an analysis of how
barcode technology is helping the company improve their SCM processes.
The articles review most aspects and processes of the new system and
outline the benefits realized post implementation.
RFID technology has had a number of substantial technology advancements
of late and as both of these articles were written in 1998, alternative RFID
technology has not been compared in the case studies, which would have
made the case studies much more applicable to this thesis.

Feasibility Study
A feasibility study is made to see if the project on completion will serve the
purpose of the organization for the amount of work, time and effort spent on
it. Feasibility study lets
• The developer to foresee the future of the project and its usefulness.
• Finding out whether a new system is required or not.
• Determining the potentials and drawbacks of the existing system.
• Identification of user requirements and the benefits expected by the user
from the resulting system.
• Finding out the various alternatives available.
• Knowing what should be incorporated in the new system.
• Defining the ingredients and objectives involved in the project. Identifying
whether the proposed system could meet the end needs of the users.
• Providing technical, economic
• Operational Feasibility The proposed system must be evaluated from the
technical point of view first, and if technically feasible their impact on the
organization must be assessed. If compatible, operational system can be
devised. Then they must be tested for economic feasibility.
29. P a g e | 29
3.1 Technical Feasibility
Technical feasibility study deals with the hardware as well as the software
requirements. The scope was whether the work for the project is done with
the current equipment and the existing software technology has to be
examined in the feasibility study. The outcome was found to be positive.
Technical Feasibility The project appears to be technically feasible. The
system can be developed using web-based, Application-based technologies,
such as C#, Asp.Net and for the user interface, Database management
systems like MSSQL can be used to store Barcode information and Barcode
Verify records. The required technologies and resources are commonly
available, and the development team should possess the necessary expertise.
3.2 Market Analysis
The market for online leave management systems is growing rapidly, as
organizations are increasingly adopting digital solutions for HR processes.
The target market includes businesses of various sizes and industries that
require an efficient and centralized leave management system. Competition
may exist from other software vendors providing similar solutions, but the
unique features and user-friendly interface of this system can give it a
competitive edge.
3.3 Economical Feasibility
The developing system must be justified by cost and benefit a criterion to
ensure that effort taken on the project give the of organization towards the
development of the project. All the operational aspects are considered
carefully. Thus, the project is operationally feasible.

Advantages and Disadvantages
9.1 Advantages
1. Universal
Barcodes are universally accepted technology. They are used behind almost
all of the retail items all around the world. Therefore, using a barcode reader
these products can be read wherever you are present in the world.
2. Accuracy
Human errors can cause problems in every face of the business. Using
barcode readers, the users can significantly reduce the number of mistakes
happening. A barcode reader is considered to be highly accurate than
entering data by hand. Even higher than a RFID technology. Regardless of
the material on which they are scanned, their accuracy remains the same.
3. Productivity
The ability to track data fast and accurate can lead to better decision making
in each department. Thus, the overall productivity of the company is
increased.
4. Time Savings
Always the data of a barcodes are readily shown since the information’s are
directly scanned. Within a fraction of seconds all the necessary details of the
product is given. This is especially beneficial in grocery stores where
62. P a g e | 62
customers purchase multiple items and each needs to be scanned
individually. Hence, there is very minimal amount of time wasted.
5. Employee Training
The entire training process of a barcode reader is less expensive and simple.
Within a shorter duration, the employees can learn how to use them without
the compensation of other co-workers. Therefore, the training times are
reduced notably for new employees.
6. Inventory Control
Barcode readers makes it easier for the inventory control so precisely.
Whatever the items those are scanned, the informations are passed onto a
computer instantly so that they are calculated through stock inventory. As a
result, they are able to provide inventory status about individual products as
well as company's overall inventory.
63. P a g e | 63
9.2 Disadvantages
1. Cost
For using a barcode technology, a barcode reader must be purchased which
is quite expensive. The prices are even higher if it is a 2D barcode scanner.
Particularly, for small businesses this cost cannot be justified. A separate
analysis needs to be done for ensuring that the investments of a barcode
reader will be beneficial.
2. Range
In order for a barcode reader to be able to function, it should not be kept
above 15 feet from the barcode label. If it is placed more than that, the
barcode reader will have a problem scanning. For some applications, this
shorter range can cause difficulties.
3. Physical Damages
Barcode readers are easily vulnerable to physical damages. Similar to other
equipment’s, it is too subjected to wears and tears. If it undergoes
damages, it can cause additional costs in repairing.
4. Label Damages
Typically, barcodes are printed on labels which is always exposed to outer
world. This makes it easily prone to environmental damages. Even if one
part of the label is damaged, it can pose problems while scanning.
64. P a g e | 64
5. Information’s
Barcode readers are able to scan only limited number of information.
Those information’s are only about the product and manufacturers.
information about manufacture date and expiry dates are not included.
6. Security
Not all the barcodes are genuine. There can be malicious barcodes setup by
cybercriminals. If a user happens to scan a malicious barcode, the system
could potentially be taken over by the hacker. Since the USB which
connects the scanner and the computer acts as a secondary keyboard, the
hackers could easily gain access to the operating system.
65. P a g e | 65
Chapter 10
Conclusion and Future Enhancement
10.1 Conclusion
Barcodes are just a simple, effective way to store data. That data can be
manipulated, stored, or tracked in dozens of different ways to help
eCommerce businesses stay efficient and organized.
They have been proven over decades of use to be reliable and inexpensive,
and their popularity shows no signs of slowing.
You can implement a barcode system in a few hours while spending
virtually nothing, making it tough to find something to complain about this
technology. For any business looking to stay organized, efficient, and error-
free, barcodes a must-have.
66. P a g e | 66
10.2 Future Enhancement
Barcode Scanning and the Future
With the recent trends of continuous barcode breakthroughs, the future
remains bright. From the innovative bar code scanners for iOS and
Android mobile devices to the lauded bar code apps for Google Glass,
today is indeed an exciting time for barcode scanner manufacturers, retail
businesses, and consumers alike.s
How bar code scanning via Google Glass Works
Since the introduction of Google Glass, app developers have been hard
at work developing innovative applications for the wearable device. From
law enforcement use to apps that allow an individual to control the
functions of an electric car, the software being created for Google Glass
is truly cutting-edge. There are even Google Glass apps that are sure to
win plenty of consumers’ hearts: barcode scanning apps.
Other Barcode Technology Breakthrough Coming Soon
The invention of 2D barcodes (QR codes) is probably the biggest
innovation in barcode technology yet. Coupled with camera-based image
readers, 2D barcodes have opened doors for barcode technology
developers to build solutions and devices tailored to specific industries.
