Conclusion

4.  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

5.  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

6.  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

7. 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

17.  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
