This document discusses RFID technology and its applications. It defines RFID and its components, including tags, readers, and antennas. It describes the different types of tags and provides examples of current RFID applications in various industries like retail, transportation, and supply chain management. The document also summarizes the results of an online survey on RFID benefits and presents opportunities for further development and use in medical and library settings.

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
