1) RFID uses radio frequencies to electronically identify objects. Tags carry data like serial numbers that readers can access without line of sight. 2) RFID has applications in access control, asset tracking, supply chain management, and electronic toll collection. 3) A survey found that respondents saw potential RFID applications in document management, inventory control, library management, and logistics. Further development is needed in medical uses and library management to realize more benefits.

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 from the field
distances of the chip’s generated by the
several meters circuitry, resist reader
interference and • without having an
circumvent a lack active transmitter
of power from the to transfer the
reader signal due information stored
to long distance.
• They are different
from active tags in
that they only
transmit data at
the time a
response is
received

7. APPLICATIONS

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
