RFID consists of tags that carry identifying information and readers that can access that information wirelessly. There are three main types of tags: passive, semi-passive, and active. RFID has applications in areas like access control, asset tracking, supply chain management, toll collection, and more. A survey found that businesses see benefits like improved efficiency, reduced costs, and increased inventory turnover from using RFID. Further development of RFID is ongoing in medical and library uses.

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

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
