3. RFID



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. Rfid component

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. Rfid tag



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

6. Types of RFID Tags
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



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
