What is RFID? Radio-frequency identification (RFID) is an automatic

identification method, replying on storing andremotely retrieving data using devices called RFID tags

or transponders. - Wikipedia Smart card or integrated circuit card (ICC) is defined

as a pocket-sized card with embedded integratedcircuits which can process information. This implies

that it can receive input which is processed by way ofthe ICC application. - Wikipedia

Difference between Barcode and RFID

Information can be read from RFID tags much faster than from barcodes

Several items in a stack/counter can be read at the same time using RFID

Items do not have to be handled one-by-one nor removed from the shelves

Inventory-taking is no longer a tedious operation RFID can stand more than 10,000 read/write

RFID can have theft bit which can be in two states ON/OFF

Shelf verification/rectification can be done on daily basis

More information can be written in the RFID tag on incremental basis

Need not open/remove books to capture information

Items are identified on upper and lower shelves more comfortably

Five important sentences about

RFID for Library RFID tags replaced both the EM Security strips and

Barcode.

They simplify patron self check-out and check-in. They have the ability to handle materials without

exception for video and audio tapes.

Radio Frequency anti-theft detection is innovative and

safe. It is high-speed inventory and identifies items which

are out of proper order.

TAGS RFID tags that are electronically programmed with unique

information. Flexible, paper-thin smart labels that are applied directlyto library items. Each RFID tag contains a tiny chip, which is bothreadable and writable and can store information to identify items in

your collection. In library applications, it also stores a security bit and if

needed, information to support sorting systems. There are two main types of tags: PassiveandActive:

Passivetags only provide information when scanned by a reader.

Activetags actively transmit data to a reader.

Within a passive tag there can be different types of microchip e.g.

Hitag1, Hitag2, EM4102, I-Code or Q5 etc.each with varying levels offunctionality; increased memory, read/write or read-only capabilities.

There are three types of tags:

Read only

Write once (WORM: Write Once Read Many)

Full read/write


10/31

Tags are also are available with different frequencies:

Low frequency (120-140Khz)

High frequency (13.56 MHz)

Ultra-high frequency (868-956Mhz)

Smart Card

The history of smart card starts with microprocessorchips, which were first manufactured in 1966 byFairchild Instruments and Texas Instruments. The ideaof using plastic cards as the carrier of microchips wasdeveloped by Jergen Dethloff in 1968.

Types of Smart Card

Integrated circuit (IC) microprocessor cards Integrated circuit (IC) memory cards

Optical memory cards

Reader

Inventory readers are used for stock verification forlocating specific item fast. During the inventorychecking process, the readers can be directlyconnected to the library servers with databases or store

the data in a pocket PC and transfer to the librarydatabase upon completion. Lets you take inventoryand locate missing items. The RFID Inventory ControlSystem consists of two parts: 1) a hand-held RFID

reader that you can use to scan items on your shelvesand 2) software developed that lets you generateinventory reports about the collected data.

AntennaA conduit between RFID tags and the coupler.

RFID antennas emit radio waves that activate

RFID tags as they pass through the activation

field. After a tag is activated, it can send

information to or receive information from thecoupler. An antenna connected to the coupler.


15/31

Coupler

The link between RFID tags and the PC. The couplercan send information in two directions: It can readinformation from a tag and send it to the PC (readmode), or it can read information from the PC and

send it to an RFID tag (write mode) PC: The link between the coupler and your library automation

system. It has developed software that runs on your PC toprovide an interface between the RFID hardware and your library

automation system. Server: A server to receive and decode the information and to

communicate with the automated library system.

System Four Phase

Library Security System Only. Using RFID Tag replace EM Security Stripe

Support Library Circulation

Using RFID tags replace the barcode in Circulation process. Reading books access number from RFID than from barcode

toborrow and return the book.

Patron Self Check-in/Check-out

Let patron do the check-out and check-in process of books. Smart and Quick Inventory

Search and Inventory by reading the RFID using portablereader and portable computer.

RFID Transponder

An RFID tag is the most important link in any RFID system. Ithas the ability to store information relating to the specific itemto which they are attached, rewrite again without anyrequirement for contact or line of sight. Data within a tag mayprovide identification for an item, proof of ownership, original

storage location, loan status and history. KEY BENIFIT

Allows check-out and check-in several items simultaneously

Information directly attached to product

Performing both identification and antitheft in one single operation Different shape and sizes available

Able to tag almost anything

Accelerate scanning and identifying


21/31

Counter Station/ Staff Station

Together with circulation module from Library AutomationSoftware, this station is used for the following services:

Editing and updating of patrons record

Add and deleting of patrons record

Generate loan history for a particular patrons

Managing of fines incurred by the patron

Arm/Disarm of EAS bit inside the library material

Program of new library material

Sort item in accordance to their branch and category number

The features of this station depend on the module loaded bythe Library Automation Software.


22/31

KEY BENEFITS:

Provide Value Added Customer Service instead of manualdaily routine

Perform media check-in/-out for those patrons who

choose not to use the self service system

Help patron that need assistance from the staff


23/31

Self check-out and check-in stationKEY BENEFITS:1. to Librarian:

Speeds up book check-in / check-out

Shelf Management System

The Shelf Management Solution makes locating andidentifying items on the shelves an easy task for librarians.It comprises basically of a portable scanner and a basestation.

The solution is designed to cover three main requirements: Search for individual books requested

Inventory check of the whole library stock

Search for books which are miss-helved

In situations when search function is required, whether fora particular item or an item category, the information isfirst entered into the portable scanner from the basestation, and when a foreign item is found on the shelves, abuilt-in beeper sound to alert the librarians.


27/31

KEY BENEFITS: 1. Changes inventory process:

No more book handling: just pass the reader across shelved books toperform an instant inventory.

Accuracy: book identification numbers are registered in the Shelf-Management Reader. The data is then downloaded to the central

database. The fastest inventory you have ever made: 20 books per second.

Notification: books to be pulled are up-loaded to the reader for quickidentification.

2. User friendly:

Light weight Wand allows easy reading of high and low shelves

3. Saves time and resources: Implementers indicate a 75% reduction in human resources required

for shelf management activities.

RFID EAS Gate/ Anti theft Detection

The RFID EAS Gate is the anti-theft part of the RFID Library ManagementSystem using the same RFID tags embedded in the library items. Each lane isable to track items of 1 meter or more and would trigger the alarm system whenan un-borrowed item passed through them. The alarm will sound and lights onthe gate will flash as patron passes through with the library material.

The EAS Anti-Theft Gate is used to detect RFID tag that is equipped with EAS

(Electronic Article Surveillance). It can detect the RFID tags within 1 meterrange without interference of magnetic items, upon detecting of Armed RFIDtags, the alarm will sound on the gate. It has option to trigger a Camera torecord patrons who trigger the alarm to the Surveillance Station.

Theft detection is an integral feature of the chip within the tag. It is a stand-alone technology, which operates independently of the library database.

FEATURES: Detect EAS Armed RFID tags Multi-item detection Able to integrate camera with the gate (Option) Gale to integrate with Surveillance Station (Option)


29/31

KEY BENEFITS:

Single technology is required for both inventory and theft

management of the library. Library staff is alerted immediately when un-borrowed items

passes through the theft detection gates.

Would-be thieves are deterred by the physical presence of

the gates. Number of patrons passing through

the gantry is captured by a

counter on the gates Alarm volume

can be easily controlled.
