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 circuitry, generated by the
meters resist interference reader
and circumvent a lack • without having an
of power from the active transmitter to
reader signal due to transfer the
long distance. information stored
• 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
