RFID- Process

Applications of RFID

• Asset management.• Production Tracking.• Inventory Control.• Pricing and Promotion.• Shipping & Receiving.• Regulatory Compliance.• Returns & Recall Management.• Transportation.• Service and Warranty Authorizations.

Advantages &

Concerns Surrounding RFID

• Advantages:- standardized and scalable approach. - reliable and cost-effective.

• Concerns Surrounding RFID:- Privacy concerns.- High investment.- Health concerns.- Limited range.

• Invented in 1948 by Harry Stockman. Initial application was during World War II-The United

Kingdom used RFID devices to distinguish returningEnglish airplanes from inbound German ones. RADARwas only able to signal the presence of a plane, notthe kind of plane it was..

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

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

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

CONSTRAINTS(CONT.)• 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
