BARCODE & RFID
TECHNOLOGY
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.
FUNDAMENTAL REQUIREMENTS
The fundamental requirements of Barcode technology can be categorized
Hardware requirementsSoftware requirements
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
SOFTWARE REQUIREMENTS
◊ The following software will be required to implement the barcode technology :a) Application softwareb) System software
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.
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.
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.
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.
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.
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.
MERITS OF BARCODE TECHNOLOGY
Professional efficiency and quality of services-
Barcode technology improves the efficiency of the information professionals and the quality of the information services.
MERITS OF BARCODE TECHNOLOGY
Accelerate the functions/operations- It increases the operations of
information services.Space saved-
The space of preserving the borrowers card and the catalogue card can be saved.
.
MERITS OF BARCODE TECHNOLOGY
Increase the accuracy of services- It increases and ensures the
accuracy of information services.
Time saved- Save the time of the users as well
as information professionals.
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.
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.
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.
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.
DEFINITION OF RFIDRFID 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).
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.
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
RFID ARCHITECTURE:
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.
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.
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.
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.
RECOMMENDATION :
To install REFID system at strategic location
Comprehensive Design to ensure the full coverage
Embedded exiting staff card with RFID Chip.
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.

BARCODE VS RFID TECHNOLOGY
advantage Barcodes have less security than RFID;
as they can be more easily reproduced or forged
Barcode RFID
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.
BARCODE VS RFID TECHNOLOGYBarcode 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.
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.
