This document discusses radio frequency identification (RFID) technology. It describes the basic components of an RFID system including RFID tags, readers, and application software. It outlines the different types of RFID tags based on frequency and read range. Examples of current RFID applications are provided such as payment systems, access control, and electronic toll collection. The results of an online survey of small and medium enterprises on the benefits of RFID in different industries are presented. The document concludes that while RFID provides benefits like contactless reading and adding data, costs remain relatively high and standards are still being developed.

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
