This document discusses RFID (radio frequency identification) technology. It describes the basic components of an RFID system including RFID tags, readers, and software. It outlines different types of RFID tags and provides examples of current RFID applications in various industries like access control, asset tracking, transportation, and retail. The document also summarizes the results of an online survey that found benefits of RFID include improved efficiency, enhanced customer satisfaction, and reduced costs. It concludes that while RFID offers advantages over barcodes, costs remain relatively high and standards are still being developed.

3. 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

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

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

6. Types of RFID Tags
Active Tags
•Use a battery
•communicate over
distances of several
meters
Semi-passive Tags
•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 thetime a
response is received
Passive Tags
•Derive their power
from the field
generated by the
reader
•without having an
active transmitter to
transfer the
information stored
