The document discusses Radio Frequency Identification (RFID) technology. It provides information on RFID components including tags, readers, and antennas. It describes the different types of RFID tags as passive, semi-passive, or active. Applications of RFID technology are outlined across various frequency ranges for uses such as access control, asset tracking, supply chain management, and electronic toll collection. A survey was conducted on opinions of RFID and its applications among small and medium enterprises. Results showed responses from education, manufacturing, retailing, warehousing, transportation and other sectors. The document concludes that RFID provides benefits over barcodes but also has limitations in cost and signal interference.

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
ActiveTags
• Use a battery
• communicate over
distances of several
meters
Semi-passiveTags
• 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
PassiveTags
• 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
