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
RFID

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
RFID components

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
RFID Tag

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 of active transmitter to
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

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
