Conclusion





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


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






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

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

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

  • 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
