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. Current Applications
• Active Tags
• 1. Use a battery
• 2. communicate over
distances of several
meters
• Semi-passive Tags
• 1. 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.
• 2. They are different
from active tags in that
they only transmit
data at the time a
response is received
• Passive Tags
• 1. Derive their power
from the field
generated by the
reader
• 2. without having an
active transmitter to
transfer the
information stored

17. 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
