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
• 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

16. 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
