This document discusses RFID (radio frequency identification) technology. It describes the basic components of an RFID system including RFID tags, readers, and application software. It outlines the different types of RFID tags and their operating frequencies and read ranges. The document also provides examples of RFID applications in various industries and the results of a survey on opinions about RFID technology and its potential uses. It concludes with a discussion of both the positive and negative aspects of RFID systems.

3. 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. 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. 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. 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 the
time 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

15. Positive
RFID is a contactless reading technology and can
read through other materials
Hold more data than barcode does
RFID tags data can be changed or added
More effective, bring lots of convenience to us
Negative
Cost is relatively remain high (compare to barcode)
RFID signals may have problems with some
materials
RFID standards are still being developed
