yRFID is a generic term that is used todescribe a system that transmits the

identity (in the form of a unique serialnumber) of an object or personwirelessly using radio waves.

y

It is grouped under the broad category of automatic identificationtechnologies.

In 1946, Leon theremin invented an espionage tool for

the soviet union which re transmitted incident radio

waves with audio information.

It has been attributed as a predecessor to RFIDtechnology.

Mario Cardullo¶s in 1973 was the first true ancestor of

modern RFID, a passive radio transponder with

memory

y The original business plan presented 1973 toinvestors showed uses in

Transportation -automatic vehicle identification,automatic toll system, electronic license plate,vehicle routing, vehicle performance monitoring.

Banking-electronic cheque book, electronic credit

card.

Security-personnel identification, automatic gates.

Medical-identification, patient history & etc.

A basic RFID consist of three components.

RF Reader (A transceiver)

RF Tag(A transponder) Software for data

processing.

8/7/2019 MIS RFID (2)


y Transponder which receives a radio

signal and in response to it sends out aradio signal.

y An antenna, and a small chip

y The antenna emits radio signals toactivate the tag and to read and write

data to it.

y Programmed at manufacture or oninstallation

y High power electromagnetic field

y The field allows the chip/antenna toreflect back an extremely weak signalcontaining the data

y LF ± 125KHz to 134.2KHz, 1 inch

y HF ± 13.56MHz, 18 inches

y

UHF ± 868MHz to 915MHz, 20 feets

y An RFID reader is a device that isused to interrogate an RFID tag.

y The reader has an antenna thatemits radio waves;

y the tag responds by sending

back its data.y The reader decodes the data

encoded in the tags integratedcircuit(silicon chip)and the datais passed to the host computerfor processing.

y T

he reader has two basiccomponents A scanning antenna A transceiver with a decoder to

interpret the data

8/7/2019 MIS RFID (2)


Information sent to and read from RFID tags by a reader usingradio waves.

An RFID reader transmits an energy field that wakes up the tag

to respond to the reader. Data collected from tags is then passed through communication

interfaces(cable or wireless)to host computer systems in thesame manner that data scanned from bar code lable is capturedand passed to computer system for interpretation, storage andaction.

To enable data to be transmitted by a portabledevice,called a tag,which is read by an RFID readerand processed according to the needs of a particular

application.RFID technology is been used by thousands of

companies for a decade or more because of its ability to track moving objects.

y Fastest, easiest, mostefficient way to track,locate & manage library materials

y Efficient Book circulationmanagement

y Automatic Check-in andCheck-outy Library inventory tracking

in minutes instead of hours

y Multiple books can be

read simultaneously y Unique ID of the RFID tag

prevents counterfeitingy Automated material

handling using conveyor &sorting systems

y An RFID tag is the most important

link in any RFID system.y Store information relating to thespecific item, rewrite again withoutany contact or line of sight.

y Data provide identification for anitem, proof of ownership, originalstorage location, loan status andhistory.

y Integrated circuit and an antennacombined to form a transponder

y Operate from a Radio Frequency (RF) field emitted by a reader device.

y Multi-read" functiony It is thin, f lexible & laminated

between paper and plastic.

y Checking of status of library material is easy.

y The staff puts the item on the reader andclick on the view to display the informationstored inside the tag and status.This station is used for the following

services:Editing and updating of patrons recordAdd and deletingGenerate loan history Managing of fines incurredArm/Disarm of EAS bit inside the library materialProgram of new library materialSort item in accordance to their branch andcategory numberThe features of this station depend on themodule loaded by the Library Management Software

y Self Check-out station is basically a computer with a touchscreen and a built-in RFID reader, plus special software

y After identifying the patron with a library ID card, abarcode card, or his personal ID number (PIN), the patronis asked to choose the next action (check-out of one orseveral books).

y After choosing check-out , the patron puts the book(s) infront of the screen on the RFID reader and the display willshow the book title and its ID number (other optionalinformation can be shown if desired) which have beenchecked out.

y The patron then confirms that he has finished the check-out process and a receipt is printed, showing which bookshave been borrowed and the return date. The RFID tag inthe book is set on quiet as a result no alarm will go off atthe EAS gates.

y It is also possible to use the station for Check-In (return)of books. In this case the patron identifies herself, choosesreturn and then puts one book or a stack of books ontothe reader. She will receive a receipt. If the books were tobe taken through the gate now, an alarm would sound.

y One important point for library productivity is that thewhole process is significantly less time consuming thanwith barcode and magnetic strip system; therefore longlines are avoided and fewer stations are needed for thesame process.

y The Book Drops can be located anywhere, within

or outside the library. Possible remote locationsoutside the library include MR T/train stations,shopping centers, schools, etc.

y This offers unprecedented flexibility andconvenience of returning library items at anytimeof the day, even when the library is closed.

y Patron inserts the library item into the slot.y The reader captures the electronic signature and

sends to backend system for loan cancellation.y Patron is acknowledged by beeping sound and

flashlight. Patrons record is updated immediately.y This is possible due to the seamless link between

LibBest Library RFID Management System and thehost computer system.

y As such, users who have reached their loan quotacan start borrowing items once they have returnedthem through the Book Drop.

y The Shelf Management Solution makes locatingand identifying items on the shelves an easy task

for librarians. It comprises basically of a portablescanner and a base station.

y The solution is designed to cover three mainrequirements:

Search for individual books requested

Inventory check of the whole library stock

Search for books which are miss-helvedy All these functions are performed by sweeping

the portable scanner across the spines of thebooks on the shelves to gather their identities.

y In an inventory check situation, the identitiescollected are compared with the database and adiscrepancy report could be generated.

y In situations when search function is required,whether for a particular item or an item category,the information is first entered into the portablescanner from the base station, and when a foreignitem is found on the shelves, a built-in beepersound to alert the librarians.

y RFID is said by many in the industry to be thefrontrunner technology for automatic identificationand data collection.

y The biggest, as of yet unproven, benefit wouldultimately be in the consumer goods supply chainwhere an RFID tag attached to a consumer productcould be tracked from manufacturing to the retail

store right to the consumer's home.

8/7/2019 MIS RFID (2)


y Though the RFID cannot completely replace the barcode

technology due to higher cost accuracy, speed and thereturn on investment is high in RFID system.

y The retailers, manufacturers and consumer goodscompanies like CVS, Tesco, Prada, Benetton, Wal-Mart and

Procter & Gamble are now implementing the technology and exploring the impact of the technology on theirbusiness.

y Others can also take advantage of RFID.The basis of success lies in understanding the technology and otherfeatures to minimise the potential problems.

y It is high time that Indian apparel industry should startutilising the new technology such as RFID in variousapplications such as manufacturing, and storing purposes.
