Radio Frequency Identification


RFID

is a method of remotely storing and
retrieving data using devices called
RFID
tags
. An RFID tag is a small object, such
as an adhesive sticker, that can be
attached to or incorporated into a product.
RFID tags contain
antennae

to enable
them to receive and respond to radio
-
frequency queries from an RFID
transceiver

Types of RFID tags



Passive RFID tags do not have their own power
supply: the minute electrical current induced in
the antenna by the incoming radio
-
frequency
scan provides enough power for the tag to send
a response. Due to power and cost concerns,
the response of a passive RFID tag is
necessarily brief. Lack of its own power supply
makes the device quite small: commercially
available products exist that can be embedded
under the skin. Passive tags have practical read
ranges that vary from about 10 mm up to about
5 meters.

Types of RFID Tags


Active RFID tags, on the other hand, must
have a power source, and may have
longer ranges and larger memories than
passive tags, as well as the ability to store
additional information sent by the
transceiver. At present, the smallest active
tags are about the size of a coin. Many
active tags have practical ranges of tens of
metres, and a battery life of up to several
years.

Categorization of Tags



Low Frequency (125 to 134 KHz)



High Frequency (13.56 MHz)



Ultra High Frequency (868 to 956 MHz)



Microwave (2.45 GHz)



Application Areas @ IIT Madras


Library Security


Transactions


Location of Publications


Users Autonomy


Users Dependent Services


Stock Management

RFID Technology: Advantages



It has the capability for multiple
applications


It provides effective and efficient library
detection system


It has provided full autonomy to users in
library transactions. They can issue and
return the books as and when they need
irrespective of the availability of staff


RFID Technology: Advantages


It has improved users satisfaction
substantially


It has enhanced the security level of
collections


It has removed various repetitive work
carried out by the staff


It has enabled us to update the database
in real time environment


RFID Technology: Advantages


It offers very high security. Each tag is
identified by a Unique Identification
Number (UIN), which can be either factory
or manually programmed and then
password protected. The excellence of this
tag is that the data on the chip that uses
sophisticated algorithm techniques cannot
be duplicated or manipulated. Hence
making it the perfect tool for Secure
Access Control.

RFID Technology: Advantages


The potential problems associated with
substandard print quality of barcodes,
which in turn leads to scanning and
reading problems


It has enabled self check in/Check out
System

Application: Electronic Book Drop




Guidelines


Book for Return Should have RFID Tag


Place Only one Item at a Time on the
Book Platform


On seeing the Message, “ Please Drop
Item Now”


Push the Book against the Flap & Drop
into the Bin


Once You have return all Items, Press
Receipt Button on Right Hand Side and
Collect your Receipt

Self Check in/Check Out System


Guidelines


Book for Self Borrowing should
have RFID Tag


Touch the Borrow Icon on the
Screen


Place and Hold your Smart Card
Near the Reader marked

Scan Card here



You will see Your ID and Name on
the Screen


Guidelines


Place the Books to be borrowed
on Book Platform


Wait until the Loan is confirmed and
you see a Message “
Item Checked Out”


Remove the Book and put another
Book if any to be borrowed


Touch the Print Receipt or Exit Icon
to get a Receipt of the Transaction

Conclusion


Integration of RFID with digital
libraries will ensure considerable
security and facilitate the librarians
and information scientists to provide
more value added services to users
community in digital environment
and work comfortably for digital
future.
