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 Semi-passive Tags Passive Tags
• Use a battery • Contain built-in • Derive their power
• communicate over batteries to power from the field
distances of several the chip’s generated by the
meters circuitry, resist reader
interference and • without having an
circumvent a lack active transmitter to
of power from the transfer the
reader signal due to information stored
long distance.
• They are different
from active tags in
that they only
transmit data at the
time a response is
received

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
