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
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
• 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
