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 components
 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
 3 types
 Passive
 Semi-passive
 Active

6. Types of RFID Tags
Active Tags Semi-passive Tags Passive Tags
•Use a battery •Contain built-in •Derive their power
•communicate over batteries to power the from the field
distances of several chip’s circuitry, resist generated by the
meters interference and reader
circumvent a lack of •without having an
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

15. Conclusion
 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
