this a presentation of bar code vs RFID.

1. BARCODE
& RFID
TECHNOLOGY

2. DEFINITION OF BARCODE TECHNOLOGY
A barcode is series of bars and spaces arranged to
a set of rules that determines how data is to be
represented. Different bars and spaces patterns are
used to express different symbols. These symbols
are readable only by a scanner. In fact, barcode
technology is an identification tool that provides an
accurate and timely support of the data requirement
for proper management systems.

3. FUNDAMENTAL REQUIREMENTS
 The fundamental requirements of
Barcode technology can be
categorized
 Hardware requirements
 Software requirements

4. HARDWARE REQUIREMENTS
 The following hardware will be required for
implementing barcode technology:
 i)Scanner: is required for reading and scanning the
information.
 ii)Printers: Three categories of the barcode printers
are available, which are as follows: Laser printers,
Thermal printers and Impact printers.

 Each technology is suited for certain kinds of
applications, and no one technology is best for all.
 iii)Decoder
 iv)Data entry terminal

5. SOFTWARE REQUIREMENTS
◊ The following software will be
required to implement the barcode
technology :
a) Application software
b) System software

6. USE AND APPLICATION OF BARCODE TECHNOLOGY
Member identification :
The barcode can be useful for checking
the authorized user of the library. A
barcode reader can be installed at the
gate of the information institutions to give
permit to the valid user of the information
institution or library. The computer will
provide the alarm and thus restricts the
entry of the illegal user.

7. USE AND APPLICATION OF BARCODE TECHNOLOGY
Circulation:
In barcode environment, the tedious process
of issue and return can be avoided. The
information user can submit his/her identity
cards to activate the borrowing status. This
step, computer scan the documents for
accession number and is issues to the user.

8. USE AND APPLICATION OF BARCODE TECHNOLOGY
User statistics
The barcode facilitates in preparing the list
of the user who are using of the library and
their arrival and departure time and can
avoid doing entries in the register manually.

9. USE AND APPLICATION OF BARCODE TECHNOLOGY
Checking the gate :
When user leaves the library with the
documents library with the documents , the
accession number of that document can be
scanned by the scanner informed whether it
is issued or not.

10. USE AND APPLICATION OF BARCODE TECHNOLOGY
Issue of no due certificate:
When a member leaves the organization, his
membership is cancelled and the information
institutions no due certificate. This
processes is time consumed than traditional
systems.

11. USE AND APPLICATION OF BARCODE TECHNOLOGY
Stock verification:
Weeding out of the resources and updating of
records also become simpler through this
process. This technology helps to verify the
stock of the information institutions
systematically, quickly and accurately.

12. MERITS OF BARCODE TECHNOLOGY

It increases and ensures the accuracy of
information services.
Time saved-
Save the time of the users as well as
information professionals.

15. MERITS OF BARCODE TECHNOLOGY
Data integrity-
It ensures data integrity and data
consistency.
Creates positive user attitude-
It creates and establishes positive user
attitudes towards the information institutions.

16. DEMERITS OF BARCODE TECHNOLOGY
Lack of consciousness among the users-
The user may not press the barcode identity
card on the scanner kept on the main gate. One
staff has to be deputed at the gate for checking
whether users are pressing their identity card or
not.
In case of violation of law, one employee needed-
If any user violate any rule, one employee has
to be there for instant checking.

17. DEMERITS OF BARCODE TECHNOLOGY
Problems of internet and electricity-
At the circulation section, the network systems
and electricity problems should not come in this
process otherwise these weakness decrease the
efficiency of the system.
Problems of pasting barcode labels-
To paste the barcode labels and to scan the
barcodes from the documents is time consuming.

18. DEMERITS OF BARCODE TECHNOLOGY
Problems of software-
If the library automation software is not efficient,
it may create problems to use barcode technology.
Costly-
To make the infrastructure for barcode
technology, it will require adequate funds. So
barcode technology is costly.

19. DEFINITION OF RFID
RFID is an automatic identification
technology that can be used to provide
electronic identity to an item object.
A typical RFID system consists of
transponders (tags ), readers(s), antennas
and host (computer to process the data).

20. RFID MIDDLEWARE
Radio Frequency Identification (RFID)
middleware is a new class of software which
facilities data and information communication
between automatic identification physical layer
and enterprise applications. It provides a
distributed environment to process the data
form tags read by the readers, translates the
data where necessary and routes it to a variety
of backend applications using suitable
technologies such as WEB, remote and
Windows Services.

21. BENEFITS OF RFID:
 Automatic monitoring without the staff
realize.
 No need enforcement
 Low cost due to the less number of controller
and reader.
 More coverage- Cover wider area
 Less maintenance

22. RFID ARCHITECTURE:

23. HOW IT WORKS:
 It provides a distributed environment to
 process the data form tags read by the
readers
 Translates the data where necessary
 Routs it to a variety of backend applications
using suitable technologies such as Web,
Remote and Windows Service.

24. WHY IT IS IMPORTANT
 Towards this end , industry is looking for a
new paradigm which can provide
 Real time visibility for most of the activities to
the collaborating partners involved
 Activities which are in the forefront of this
plan, are management and tracking theft
prevention access restrictions and security
hazardous material management and others.

25. UNIQUENESS OF RFID:
 RFID does not require line of sight access to
communicate
 Without requiring physical contact
 Multiple tags can be identified
 Tags mounted on products of consignments
can survive in harsh environments such as
extreme temperatures, moisture and tough
handling.

26. RFID FEATURES :
The strong interest shown by industry in RFID is
mainly on account of the following features which
potentially would lead to better business and
workflow process:
 Tags can store or archive data which can be updated
during various stages of the process
 Automation of data collection at a huge rate
climinating the need for manual scanning
 Accurate data collection hence less problems due to
erroneous data for decision making.
 Less handling of goods and hence less labor required
simultaneously identification of multiple tagged items
in the read area.

27. RECOMMENDATION :
 To install REFID system at strategic location
 Comprehensive Design to ensure the full
coverage
 Embedded exiting staff card with RFID Chip.

28. BARCODE VS RFID TECHNOLOGY
What is it?
A barcode is a visual representation of data
that is scanned and interpreted for
information. Each barcode contains a certain
code which works as a tracking technology
for products.
Radio Frequency-Identification technology
(RFID) involves a tag affixed to a product
which identifies and tracks the product via
radio waves.

Barcodes have less
security than RFID; as they
can be more easily
reproduced or forged
Much smaller and lighter
than RFID tags and
therefore easier to use.
The security system of RFID
is better than barcodes.
Can read RFID tags from a
greater distance than
barcodes.

30. BARCODE VS RFID TECHNOLOGY
Barcode RFID
B-Less expensive than RFID
tags; as barcodes are directly
printed onto plastic or paper
materials
Barcodes have only reading
capabilities
In many cases; barcode
accuracy has been said to be
the same or even better than
RFID tags.
RFID technology is more expensive
than barcode technology.
RFID tags are read/write devices
On the other hand, RFID tags are
less accurate than barcode
technology in some cases.

31. BARCODE VS RFID TECHNOLOGY
 Disadvantages
Barcode RFID
Barcode scanners need a
direct line of sight to the
barcode to be able to
read.
In order to read the
barcode, the barcode
scanner needs to be quite
close; around no more
than 15ft
Can read RFID tags from a
greater distance than
barcodes.
. RFID tags don’t need to
be positioned in a line of
sight with the scanner.
