WHAT IS RFID ?

• RFID STANDS FOR RADIO FREQUENCY IDENTIFICATION

• IN THIS PRESENTATION I AM GOING TO HIGHLIGHT THE USE OF RFID IN BIT

OBJECTIVES OF THE STUDY • ADVANTAGES AND

DISADVANTAGES FACED IN USING RFID

• WHY USE RFID OVER BAR CODE

• OVERALL FUNCTIONING IN VARIOUS LIBRARY OPERATIONS

• HIGHLIGHT THE HARDWARE COMPONENTS REQUIRED FOR THE USE OF RFID

RFID VS BAR CODE

• READ ONLY

• NEEDS DIRECT VISIBLE CONTACT

• SINGLE ITEM SCAN ONLY AND DOES NOT PROVIDE SECURITY TO THAT EXTENT

• EACH BOOK HAS TO BE SCANNED INDIVIDUALLY

• READ & WRITE SYSTEM• NO LINE OF SIGHT,

ALIGNMENT OR POSITON REQUIRED

• FLEXIBLE TECHNOLOGY WHICH COMBINES SECURITY & ITEM IDENTIFICATION IN A SINGLE TAG

• STOCK VERFICATION MADE EASIER & FASTER AS THERE IS NO NEED OF TAKING BOOKS OUT FROM THE RACKS

RFID VS BAR CODE

• ELECTRONIC ARTICLE SURVELLIANCE SYSTEM OFFERS A TIGHT SECURITY CONTROL OVER LOSS OF BOOKS

• REDUCES HUMAN INTERVENTION TO A GREAT EXTENT , CAN ACT AS A SELF CHECK SYSTEM

• INFORMATION ON THE TAG CAN BE UPDATED WITHOUT REMOVING THE TAG FROM THE BOOK

• IT IS NOT THE CASE WITH BAR CODES

• SYSTEM IS MORE TIME CONSUMING AS A SINGLE ITEM HAS TO BE SCANNED SEPARATELY.

• RESTRICTIONS ON UPDATING INFORMATION ON A BARCODE

HARDWARE COMPONENTS OF RFID

• SMART LABELS

• RFID CARDS

• MID RANGE READER & WRITER

• APPLICATION SOFTWARE

RFID CARDS

• RFID INLAY IS INSERTED IN A PLASTIC CARD

• CARD HAS AN ELECTRONIC CHIP AND AN ANTENNA IN IT LIKE A TAG , INSTEAD OF A BARCODE

2

SMART LABELS

• Based on 13.56 MHZ – a worldwide standardized frequency

• Libraries use high frequency passive tags

• In our library we paste these tags on the preface page of the book

MID RANGE READER

• IT IS CONNECTED TO A WORKSTATION OR A NETWORK

• READER IS ATTACHED TO A PAD ANTENNA , ON WHICH THE BOOKS ARE PLACED

• SUPPORTS ALL RFID FUNCTIONS, ALLOWING IDENTIFYING MULTIPLE LABELS

CONSTRAINTS COUNTERED WHILE

USING RFID • MANUFACTURING OF

RFID HARDWARE IS AT A NASCENT STAGE IN INDIA

• PHYSICAL LIMITATION OF THE TECHNOLOGY IS THE INABILITY TO READ THROUGH METALS OR LIQUIDS

• EXTREMELY HIGH COST OF THE TAG IS A MAJOR LIMITATION

• CAPACITY TO READ DECREASES AS THE TAG GETS OLDER AND EVEN SOMETIMES IT IS TIME CONSUMING TO READ THE TAG THROUGH BOUNDED BOOKS

• PHYSICAL DAMAGE DONE BY STUDENTS CANNOT BE AVOIDED

• RETURNS ARE NOT VERY ATTRACTIVE AS THE COST OF LABOUR IS NOT VERY HIGH IN INDIA

• LIBRARIANS NEED TO DEPEND HEAVILY ON THE TECHNICAL PROFESSIONALS

• FURTHER RESEARCH IN THIS FIELD CAN IMPROVE THE SITUATION TO A GREATER EXTENT .

• WE CAN CONCLUDE THAT THE USE OF RFID TECHOLOGY IS AT A VERY PRIMITIVE STAGE IN INDIA
