This document discusses RFID applications. It begins by defining RFID and its components, including tags, readers, and antennas. It describes the different types of tags and provides examples of common RFID applications in various industries. These include asset tracking, supply chain management, toll collection, and more. The document also presents results of an online survey on possible RFID applications. It found that logistics, libraries, and inventory control were seen as top opportunities. In conclusion, it discusses further development areas and notes both benefits like improved data storage but also challenges like potential high costs.
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
• 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

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
