CHAPTER 1 INTRODUCTION AND PROBLEM DEFINITIONRFID (Radio Frequency Identification) is the latest technology to be used in different industries for security and theft detection. Now a day this technology is widely used in the library. In the library RFID based systems move beyond security to become tracking systems that combine security with more efficient tracking of materials through out the library, including easier and faster charge and discharge, inventory, and materials handling. The application of this technology not only able to reduced the theft of books but also reduce the manpower due to its self-check out and check in facility. RFID is one of the automatic identification or auto ID systems like bar codes, smart cards, and voice recognition etc., used to help machines identify objects. This technology is often coupled with automatic data capture systems to identify objects and capture information and transfer them into computer without data entry. Naturally, the aim of these systems is to increase efficiency and reduce data entry. RFID has been around for long time with many literatures published on it. This article is just a little extract of those, and hopes to give a high level overview of the RFID technology, its characteristics, its applications, and its relevance to Windows CE world. It is a generic term for technologies that use radio waves to automatically identify people or objects. Recently the use of RFID tags to track books, videotapes, CD-ROMs and other library collection, components has risen in popularity. Libraries are finding that RFID technology holds many advantages over traditional barcodes and antitheft tags and contributes to realize considerable labor and cost savings. The task of receiving, transporting, sorting and shelving materials has exploded in recent years. Library staff size remains constant at best while circulation and materials management continues to grow. RFID provides a solution to automate much of these handling and return staff to the business of customer service.

1.1 Need of RFID In Library Management

Figure 1.1 : Need of RFID in Library ManagementRFID is used in Library Management for providing security to it. Various transactions on book can be done by using Barcode also, but then there wouldnt be any security. It provides security to both student and book by assigning RFID tag to it. RFID is needed to be implemented in library since it reduces manpower by automation and hence manual errors are reduced to certain extent. Various transactions such as issue return book can be done at faster rate when RFID is used. RFID provides various anti-collision algorithms that can reduce the reading error when multiple books come into contact with the reader. RFID provides security to the complete system since only librarian can access the database and has the authority of looking at book inventory and transactions. So, no one else other than librarian can access the database. Hence RFID is required to be implemented into the Library Management for securing it by using anti theft detection algorithms.

1.2

Advantages of RFID in Library Management2

1.2.1 Rapid charging/discharging The use of RFID reduces the amount of time required to perform circulation operations. The most significant time savings are attributable to the fact that information can be read from RFID tags much faster than from barcodes. That is due to the fact that the tags can be read Regardless of item orientation or alignment (i.e., the technology does not require line-of-sight or a fixed plane to read tags as do older technologies) and that several items in a stack can be read at the same time. While initially unreliable, the anti-collision algorithm that allows an entire stack to be charged or discharged now appears to be working well. Finally, RFID tags can be read from distances of up to 24 inches distances far greater than the use of light pens and barcode wands used with EM technology. That is what makes RFID systems not only faster, but able to support electronic inventorying with handheld devices. Hence it does fast transactions in library and collision is also avoided. Since passive tags are used, it does not require external battery for its charging.1.2.2 High reliability

The readers are highly reliable. Several vendors of RFID library systems claim an almost 100 percent detection rate using RFID tags. Anecdotal evidence suggests that is the case whenever a reader is within 18 inches of the tags, but there appears to be no statistical data to support the claims. We are using the reader that provides 20 cm reading range. So data from the tag can be read up to 20 cm range. It gives high reliability by giving correct information. There are fewer false alarms than with older technologies once an RFID system is properly tuned RFID systems encode the circulation status on the RFID tag. This is done by designating a bit as the "theft"(EAS) bit and turning it off at time of charge and on at time of discharge. If the material that has not been properly charged is taken past the exit sensors, an immediate alarm is triggered. Another option is to use both the "theft"(EAS) bit and the online interface to an automated library system, the first to signal an immediate alarm and the second to identify what has been taken. 1.2.3 High-speed electronic inventorying

3

A unique advantage of RFID systems is their ability to scan books on the shelves without tipping them out or removing them to access the barcodes. A hand-held inventory reader can be moved rapidly across a shelf of books at a distance of approximately six inches to read all of the unique identification information. Using wireless technology, it is possible not only to update the inventory, but also to identify items which are out of proper order. 1.2.4 Long tag life RFID tags last longer than barcodes because nothing comes into contact with them. Most RFID vendors claim a minimum of 100,000 transactions before a tag may need to be replaced. Once the tag is attached to the book, it can do minimum 100,000 transactions and more than that .So for many years no need to think about replacing the tag. 1.2.5 Reduction in workplace injuries Workplace injuries caused by the repetitive motions related to flipping books and angling books under barcode readers cost libraries millions of dollars every year, and lead to pain, limited physical range, and other problems familiar to a feminized workforce. It gives very correct a result .Hence collision is avoided .There is minimum chance of book lost. 1.2.5 Streamlined inventory management Libraries spend a lot of money ensuring books are where they need to be. Books with barcodes require humans to physically remove and handle every item to ensure it is in the correct location. RFID offers the ability to analyze and correct library inventories without handling the items. 1.2.6 Provide efficiency to collection management Since no errors occur the system is efficient and the database is also consistent. Reader reads the correct information and stores it into the database.

1.2.8. Provide wireless inventory management 4

There is no line of sight or no wired connection required between the tag and the reader.Data is read by the reader using radio frequency waves captured by antenna of reader and transmitted from the antenna of tag.

1.3

What we actually do?

1.

Here RFID tag is used for books, students and the librarian.

2.

When a book is issued / returned having RFID tag, reader reads the tag information and database is updated automatically

3.

While issuing book, Reader of RFID reads the information from book RFID tag. And searches issue rules. the relevant information regarding book in the database with library book

4. While returning of book, date of return is checked with the date on which he is supposed to return in the database of student. If he has delayed then he has to pay fine as per allotted. The fine paid by him is entered into the database by librarian.

5. Here RFID Reader is used to provide security, it provides facility to display message on mobile phone if return date exceed & it also provide facility to student to access book database in the campus of library.

6. Whenever librarian wants to log-in he /she will have to use his/her RFID card. Log-in and Log-out details are automatically stored into the log database.

5

7. Searching of any student, book can be done very easily either by using his/her card, book card respectively. And in case student want to search for book then he can do it by entering any of the following fields i.e. book card no., author name, book name etc.

8. Student can also check the books issued by him, and his limit of issuing them, book return date by simply scanning his card.

Reports are generated for student, book, book issue-return etc.

1.4

Problem Definition

To implement Library Management Using RFID. This system should provide security to the library. Along with that it should also provide many facilities such as fast searching of books/members, fast transactions etc. that makes the working of system efficient. Library system provides many facilities for student, staff and other members for that purpose we use RFID technique for issuing, renewing, updating database and provide security. Here RFID tag is used for books and student when a book is issued / returned having RFID tag reader reads the tag information and database is updated automatically. RFID reader is used for reading RFID tag which is attached to book. To provide security in library from thefting of book for that purpose we display message on screen that is Book is misplaced and also student can access book database on any pc in library campus.

CHAPTER 2

LITERATURE SURVEY AND PREFETCHING

PREFACEIn this the complete survey of the existing system is done.What are the advantages in using the and why there is a need for its replacement with the new technology is studied. We have studied two systems-traditional manual system and the system using barcode.

2.1

Traditional SystemIn traditional systems, everything was done by the human being. For complete

management of library it requires a great manpower. Since transactions are done manually in this system ,there are more possibilities of errors. Here librarian had the responsibility of maintaining book inventory database ,one more person was required to maintain the database of issue/return of book ,then accountant was required for fin calculation and collection etc. It requires less cost to implement the system. 10

2.1.2

Limitation

It may happen that many student comes at the same time for either issuing or returning the book, then collision may occur. Hence database may have some invalid entries into the database.

If there is a great crowd ,then any member can take the book out of the library without the permission of librarian.

Members have to wait for a long time for issuing /returning the book. Librarians more time is wasted in performing transactions only. He cant think about library enhancement , increasing facilities etc.

Members time is wasted in searching book into the library. Sometimes it may happen that the member searches the book and requests librarian for its issue. Librarian searches for his record into the database and then gets that member cant issue more books. Hence wastage of members and librarian time.

2.2

Barcode SystemA Barcode is just a different way of encoding numbers and letters by using a

combination of bars and spaces of varying widths. This is just another way of entering data into a computer. A bar code does not contain descriptive data. It is a reference number that a computer uses to look up an associated record that contains descriptive data and other important information. For example, a barcode found on a book does not contain the book name, author, or price, instead it contains a 12 digit book_id. This book_id is captured by the barcode reader and is decoded into the format that computer can understand. When this number is scanned by the librarian at the check-out, it is

11

transmitted to the computer which finds the record associated with that book_id in the data base. The matching book record contains a description of the book, vendor name, price etc. The computer instantly does an "availability" check and displays the result. It also subtracts the quantity issued by the student. This entire transaction is done instantly. In a nutshell, a bar code typically has ID data encoded in it, and that data is used by computer to look up all specific information associated with the data.

2.2.1 Advantages Of Barcode Techniques

Transaction of book is done faster than the traditional system. Barcodes are universally accepted because they are very inexpensive and there are established standards for their use.

2.2.2 Disadvantages of Barcode Techniques

Barcode scanner scans only nearest barcode number. It has very short reading range. It does not provide any security like RFID Scanner. Book can be taken out of library when there is a crowd. It does not support Anti theft detection algorithms and Anti Collision Algorithms.

The need for the bar code to be visible. Since it required lines of sight.[1]

Around 10% reading error. At the time of reading barcode, barcode reader can not scan

barcode properly. Since it gives error.

2.3 RFID Features and Benefits in Library

Tags do not require line of sight to be read. Tags can be read from a distance and from any orientation. Tags can have read and write capabilities. Tags can easily be embedded into different products. 12

Tags encrypt data, along with an unalterable unique identification number . Tags provide permanent identification for the life of the product. RFID tags for library items would be disabled after check-out. Library databases are highly secure. Its too hard to use this information anyway.

CHAPTER 3 SYSTEM REQUIREMENT AND SPECIFICATION

3.1

Necessary Functions13

Reading tag The reader sends a radio signal that is received by all tags present in the RF field

tuned

to that frequency. Tags receive the signal via their antennas and respond by

transmitting their stored data. The tag holds a book_id. The read/write device receives the tag signal via its antenna, decodes it and transfers the data to the computer system through a cable or wireless connection. Search Book_id is searched into the computer and matched with the record. If book_id matches with the record then it displays the output as available.

Display Computer displays the list of available books on screen. it also displays whether a

member can issue more books or not. It shows the number of days delayed, issue/return date from the database.

3.2

Desirable Functions

Security This system provides security

Automation Makes the system automated

CHAPTER 4 HIGH LEVEL DESIGN AND ESTIMATION PREFACEIn this chapter project estimation is done on the basis of man power, lines of code, size of development. This is required for computing the total cost of the project during planning and deployment phase. For computing the LOC various models are being used such as COCOMO model

4.1

Project EstimationEffective software project estimation is one of the challenging and important activity

in software development. Proper project planning and control is not possible without sound and reliable estimate. The four basic steps in software project estimation are: Estimate the size of development product .The units of measure are Lines of Code (LOC). Estimate the effort in person-months or person-hours. Estimate the scheduling calendar months. Estimate the project cost in dollars (or local currency).

In this amount of work, resources and the time required to complete the project is estimated. The metrics estimated will invariably change as time progress. This exercise will help us to suitably distribute and allocate the work task equally among the members based on the time line and way time allows.

4.2

Resources

The resources that would be utilized the project life cycle are: 15

Human Resources : The project team is comprised of 4(four) members. Officially, the project is allotted 6 hours per week (h/w) over a period of roughly 8 months. Thus the available time period is: 6h/w * 4 person * 32 weeks = 768 man-hours = 33 man-months (@17 man-hours/month)

4.3

COCOMO ModelConstructive cost model is one of the most widely used and discussed software cost

estimation model. Our project is COCOMO model.the basic cocomo model complete software development effort and cost as function of program size expressed in estimated line of code. Table 4.1: Area in which project lies Software project Organic semidetached embeddeda b b b c b d b

Automated checking and result generation is software that is developed within a set of tight hardware and software constraint. The basic cocomo model takes following equation: Effort = a bKLOC b b

Duration = cbEffort d b

Duration =2.5*(10.26^0.35) = 5.64 months Number of people recommended = Efforts/Duration = 10.26/5.64 = ~ 3 people Since there are 4 project members, project duration is reduced accordingly. LOC based Estimation: The average productivity for our product is: The labour rate estimated is: 17 600 LOC/per month Rs.6600 per month

Thus the cost per line of code is: Based on LOC estimated and historical productivity data, Total estimated project cost is:

approximately Rs.11

Rs.40,500

CHAPTER 6 RISK ANALYSIS6.1 Risk Management20

6.1.1 Risk Assessment A risk is a probability that some adverse circumstance will occur. It is potential problem- it might happen or it might not. But, regardless of outcome, it is really a good idea to identify it, assess its probability of occurrence, estimate its impact and establish a contingency plan should the problem actually occur. For good software project management, understanding the risks and taking proactive measures to avoid or manage them is a key element. Risk Management is concerned with identifying risks and drawing up plans to minimize their effects on the project. Risk involves two characteristics: Uncertainty - The risk may or may not happen, i.e. there is no 100% risk problem. Loss - If the risk becomes a reality, unwanted consequences or losses will occur.

There are different categories of risks and they are as follows Project Risks Project risks threaten the Project plan. If Project risk becomes real, it is likely that project schedule will slip and cost will increase. Project risk identify potential budgetary, schedule, personnel, resource, customer and requirement problems and their impact on a software project. 6.1.2.1 Product Risks Product risks affect the quality or performance of product. It is associated with overall size of the software to be built or modified. 6.1.2.2 Technical Risks Technical risks threaten the quality and timeline of the software to be produced. If it becomes a reality, implementation may become difficult or impossible. Technical risks identify potential design, implementation, interface, verification and maintenance problems. Technical risks occur because the problem is harder to solve than we thought it would be. 6.1.2.3 Technology Risks Technology risks are associated with the availability and quality of the tools to be used to built the product. Resources required to build the software may prove insufficient. Staff Size and Experience Risks 21

6.1.2

6.1.2.4

Staff size and experience risks are associated with the overall technical and project experience of the software engineers who will do the work. Project members may get sick and this would result in a delay in completion of their respective modules. The schedules might slip as the team members are relatively inexperienced.

6.2

Customers characteristicsCustomer characteristics risks are associated with the sophistication of the customer

i.e. it includes the GUI, whether it is user friendly and guides the user in an efficient manner and also the developers ability to communicate with the customer in a timely manner.

6.3 Development EnvironmentDevelopment environment risks are associated with the availability and quality of tools to be used to build the product6.4

Risk Mitigation, Monitoring And Management (RMMM) PlanRisk Mitigation, Monitoring and Management mean risk avoidance. Avoidance is the

best strategy by adapting the proactive strategy to risk. The project manager should monitor i.e. keep a check on the project to see whether the risk is becoming more likely or not. Risk management comes into play when the mitigation efforts have failed and the risk has become a reality. Risk #1 Sophistication of the end users application program Mitigation - Develop a front end that is both user friendly and covers all needs. Monitor - Test the application with novice, expert and intermediate users. Management - Customer should be notified about the limitations and the scope of the API. Risk #2 Delay in completion of modules due to member being sick. Mitigation - Keep work of all members documented. Monitor - Review is made between members and ideas, thought, plans are discussed in meetings. 22

Management - Shift one or more members to sick members module. Risk #3 Schedule might slip due to inexperience Mitigation - The planned schedule should be followed strictly. Monitor - Check whether work is going according to time. Management - Add more members to the project or increase the working hours of already working people. Risk #4 Resources might prove insufficient Mitigation Monitor - Gather all the resources that are required and check whether they are feasible. - Check at any point of time whether the resources allocated are less and whether more resources will be required. Management - Increase the fund that is allocated to the resources or try and adjust with the existing resources.

6.5

HardwareThese can also be used instead of the GP-20 and proximity passive tags. But due to

high cost they are not used. GP 20 : This is the reader that provides reading range upto 20cm range.It receives the radio waves transmitted by the antenna of the tags. It stores this information into the database. RFID tags : It stores the unique number.

CHAPTER 7DETAILED DESIGN PREFACE

23

In Design phase actually modules are designed using the software.In this GUI is given the first importance.It should include all the modules that satisfies the user requirements.This is the only thing through which user interacts with the system.

7.1 Approaches for designThere are two approaches for designing. 7.7.1 7.7.2 Sructural Object oriented

Our project is based on Object Oriented approach. In OO A, UML diagrams are drawn.

7.2

UML DiagramsDiagrams have been drawn in Unified Modeling Language using Rational Rose

Software. These diagrams have been classified under following 5 fields:1) The User View

: It includes use case diagrams.

2) The Structural View : It includes class diagram and object diagram.

3) Behavior View

: It includes the sequence diagram, the collaboration diagram, the machine State Chart diagram and the activity diagram.

3) Implementation View : It includes the component diagram. 4) Environment View

: It includes the deployment diagram.

Scenario When member enters into the library, his/her I-card information is captured by reader and is matched with the database server. If server validates it, then member enter book-id into the system. System will search into database for its availability. If it is available then it checks that whether user can issue more books or not. If yes then member can issue it else leaves from library.

E-R Diagram

The Entity-Relationship (E-R) data model facilitates database design by allowing specification of an enterprise schema that represents the overall logical structure of database. The E-R model is very useful in mapping the meaning and interaction of real world enterprises into conceptual schema. In this E-R diagram we have used four entities such as Magazine, CD, Accession register and member, which contains information about student and staff. Transaction is considered as a aggregation relationship, as all entities have transactions. CD-transaction and magazine-transaction follows one-to-one relationship. Accession register member has many-to-one relationship. 35

CHAPTER 8 REVIEW OF DESIGNDesign phase includes that how the system is drawn, which approach does it follows and how the database is organized.

8.1

Approach

41

This project follows the Object Oriented Approach. System is represented by using structural and behavioural diagrams. Structural diagrams are class, component, deployment, package. Behavioural diagrams includes use case, state , activity. Structural diagrams shows the structure of the system and behavioural diagrams indicates that how the system flow will occur. The complete system flow is shown by using use case diagram.Various classes in class diagram represents the total entities. State chart diagram implies the different states from which an object passes.

8.2

E-R DiagramThis show the relationship between entities.It represents that how the entities work

into the system and how they are interrelated.Relationship can either be one-to-one,one-tomany or many-to-one or none. Entities require several fields for their description.These include keys such as primary ,foreign keys. In this system CD, Member, Magazine and Accession Register are entities.

8.3

Data DictionaryDatabase is required for storage of information, transactions etc. Here for this

purpose MS-Access is being used. Various databases such as borrower, book issue/return etc are developed.

CHAPTER 9 MODELLING9.1 Working Of the Complete SystemThe first step is to assign the tags to the books, members and the librarian. Tag contains the unique identity number. 42

When member enters the library, he/she searches the book at the helpdesk. For searching he must know either the name or author of the book. He retrieves the information that whether the book is available into the library or not. If he wants to issue the book and if the book is available then he takes the book and issues it with the help of the librarian. For issuing it, it is checked that whether his book issue limit is not already maximum. If it is so, then he first will have to return the book. If the book is delayed then on the last date a SMS is sent on to the members phone that he should return the book today else he will have to pay the fine. If the book is already delayed then automatically fine is calculated on his name and whenever he returns the book, he has to pay fine. For any kind of announcement, an e-mail can also be sent to the member by the librarian.

9.2

AlgorithmsWe have used algorithms for issuing, returning books.

9.2.1 Algorithm for book issue Step 1 :Member enters into the library. Step 2:He searches for the book by entering the book name or author. Step3:If it is present then he checks for the book limit.If limit is not exceeded then he issues the book else he have to return any of the previously issued book. Step4:If return date exceeds then SMS is sent.For due date he will have to pay fine. Step 5:After issuing book he leaves the library. 9.2.2 Algorithm for Returning book Step 1 :Member enters into the library. Step 2: He returns the book. Step 3:Librarian checks the due date.If due is there,then member pays fine. 43

Step 4: He returns the book and leaves the library.

9.3

Software Used: This is used for front end i.e. for GUI.

Modules

Overall working is divided into following 7 modules.

1. Login This module has been designed for authentication of administrator. He will enter the password and if password is correct then he will be considered as an administrator. His login time is also maintained into the database. Functions: Check username () Check password () Check IP address ()

2. Borrower This module has been design for displaying all the information of library members i.e. Personal, academic, issue or return record etc. Functions: Search record () Update record () Reload record () Display record () 44

3. Books It stores all the information about book. Those books that are newly purchased are given the unique accession no. and are then entered into the database. And database is updated. Functions: Add book () Delete book () Search book () Update book record () Display book info ()

4. Book issue record Book issue record will update the database as per transactions done. This database also makes use of student/staff record, accession record. Books are only issued when user has permission for it. This also maintains book return database and fine. Functions: Issue book () Return book () Renew book () Update record ()

5. Book purchase record Whenever any book is purchased, then that books entry is made in this database. And it has brought to library, and then accession register is updated by making the entry of newly purchased book. Functions: Display book info () Search () Update record ()

6. Book Return record 45

Whenever any book is return, then that books entry is made in this database and then updates the record of library member and then takes fine if not return within time period. Functions: Search record () Calculate fine () Update record ()

7. SMS module This module is used to send sms to library member if returning date is close and if any fine. Functions: Search member () Send sms ()

8. Search module In this module search the member info, zip code, book info or many other information.

CHAPTER 10 MODELLING REVIEWIn modeling, flow of the complete project is described. A tag is assigned to the member, book, and to the librarian. RFID reader captures the information from the tag whenever it is scanned. This information is stored into the database. RFID provides security to the library. Algorithms are used for the anti collision and anti theft detection. Anti collision algorithms avoids collision when multiple tags come into contact at the same time. Anti theft detection algorithms provides security to the system.If any book is taken out of the library without issuing it then these algorithms helps to detect it. Software is used for user interface and storage purpose.For GUI C#.NET is used since it has many functionalities such as crystal reports , list view that gives a great interaction to the use with the system.For storage purpose MS Access 2007 is used. It provides advanced networking functionalities. Hardware is required for provideng the required environment to the system for execution.This system uses RFID reader GP 20 for scanning the tag and retrieving the information from the tag. Passive tags are used for storing information. Prototypes are designed for user interface.They are designed in C#.NET and stores the information in MS ACCESS.These helps user to understand that what exactly he is doing.These includes the complete information that is required by him.

TESTINGPREFACETesting is the phase that starts from the requirement and gathering phase and continues till deployment phase.First testing is the unit testing that is done on a single module.Various other testing are integration,black and white box.Testing is required for checking correctness,completeness and quality of software.Debug is used for checking of bugs,defects.It increases the quality of the product.

11.1 Formal Technical ReviewsIn doing these Formal Technical Reviews, all the project members were in the review team. We had worked for around 10 hours each week for the project excluding the studies we made for it. In these hours the formal reviews were also done. In these Formal technical reviews there are some procedures we had followed. As per the routine of the we met twice a week. The components being reviewed at each meeting. As per the progress we presented the work done by each and chose the best. We work on with it till all the requirements are met. Then we tested the component for each and every requirement. After the testing we took decision whether to consider it or discard it. But time we amended it and made the component better. But when there are more failures then success then we discarded with and started it all over again. Each time reviews decisions and suggestions were documented. This test report is a part of all the documentation done during the reviews and decisions.

11.2 Test Plan11.2.1 Introduction 56

Human computer interaction currently faces the challenge of tacking advantage of new technologies, which efficiently use the capabilities of the computing systems of today and more efficiently complete user requirement. We identify that how RFID Reader is useful in library system. This paper consists of a survey of RFID Reader and Tag. There is no doubt that this software is going to be the way of the future. RFID Reader and Tag improve the library system perform some operation atomic. RFID Reader is replaced by old Barcode Scanner because RFID Reader is moer efficient and easily handle. 11.2.2 Testing Performed At the development site first we performed Unit Testing.This is done on each module individually. After that Black Box Testing. Black box testing there is no need to view coding part. It focuses on functional requirement of the software. In block box we give the input & check whether output is proper or not. After Black box testing we test modules using Regression testing. In Regression testing we test whether changed component has introduced any error in unchanged component. Regression testing focuses on retesting after changes are made. After Black box testing we conduct system testing. It has to be tested against the system specification to check it delivers the required features. It verifies the entire project after integrating all software & hardware component and validates it according to original project requirements. White box testing is performed regularly whenever their was any exception or error in output obtained from the above testing. During this we tested the code against the requirements.

CHAPTER 12 CONCLUSIONRFID (Radio Frequency Identification) is the latest technology to be used in library Management. Unlike EM (Electro-Mechanical) and RF (Radio Frequency) systems, which have been used in libraries for decades, RFID-based systems move beyond security to become tracking systems that combine security with more efficient tracking of materials throughout the library, including easier and faster charge and discharge, inventorying, and materials handling. RFID in library management reduces manual work. It leads to automation and improves security. It ensures the correct transactions.It provides security by providing tags to the member and book.It does not require line of site,hence reduces error.

RFID is one of the automatic identification or auto ID systems like bar codes, smart cards, and voice recognition etc., used to help machines identify objects. This technology is often coupled with automatic data capture systems to identify objects and capture information and transfer them into computer without data entry. Naturally, the aim of these systems is to increase efficiency and reduce data entry. RFID has been around for long time with many literatures published on it. This article is just a little extract of those, and hopes to give a high level overview of the RFID technology, its characteristics, its applications, and its relevance to Windows CE world. It is a generic term for technologies that use radio waves to automatically identify people or objects.
