This document provides an overview of RFID (radio frequency identification) technology including its components, types of tags, and applications. It describes the basic parts of an RFID system including tags, readers, and application software. Common types of tags are described as passive, semi-passive, or active depending on their power source. Example applications discussed include supply chain management, asset tracking, toll collection, and more. The document also summarizes the results of an online survey of small and medium businesses that found the most common potential applications were seen as library management, logistics/supply chain, and pharmaceutical manufacturing. It concludes by mentioning further development opportunities for RFID technologies.

3. RFID
• RFID = Radio Frequency Identification
• Electronic labeling and wireless identification of
objects using radio frequency
• Tag carries with its information
– a serial number
– Model number
– Color or any other imaginable data
• When these tags pass through a field generated
by a compatible reader, they transmit this
information back to the reader, thereby
identifying the object

4. RFID COMPONENTS
A basic RFID system consists of these components:
• A programmable RFID tag/inlay for storing item data;
• Consisting of an RFID chip for data storage
• an antenna to facilitate communication with the RFID chip
A reader/antenna system to interrogate the RFID inlay
Application software and a host computer system

5. RFID TAG
The RFID tag consists of an integrated circuit (IC) embedded
in a thin film medium.
Information stored in the memory of the RFID chip is
transmitted by the antenna circuit embedded in the RFID
inlay via radio frequencies, to an RFID reader
3 types
• Passive
• Semi-passive
• Active

6. TYPES OF RFID TAGS
passive
Semi-passive
active
• Use a battery
• communicate over
distances of several
meters
• Contain built-in
batteries to power
the chip’s circuitry,
resist interference
and circumvent a
lack of power from
the reader signal
due to long
distance.
• They are different
from active tags in
that they only
transmit data at the
time a response is
received
• Derive their power
from the field
generated by the
reader
• without having an
active transmitter to
transfer the
information stored
