Conclusion

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

Benefits of using RFID in differentindustries
Manufacturing Retailing Transportation Warehousing

13.  In medical uses and library management

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
