This document discusses RFID technology. It provides details on RFID components including tags, readers, and antennas. It describes the three main types of RFID tags - passive, semi-passive, and active - and their operating distances. Several applications of RFID are mentioned, such as using them for access control, electronic toll collection, and tracking goods in the supply chain. The document also summarizes the results of an online survey on SME opinions of RFID and its applications.

4. 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

5. 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

6. 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

7. 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

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
