Radio Frequency Identification


is a method of remotely storing and
retrieving data using devices called
. 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

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

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
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

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)

Quality and Excellence in Services


RFID Technology: Advantages

It has the capability for multiple

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

It has enhanced the security level of

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
