The document discusses radio frequency identification (RFID) technology, including its components, types of tags, current applications in various industries like logistics and supply chain management, and the results of an online survey on opinions of RFID. It also covers future development opportunities for RFID in areas like medical uses and library management and concludes that RFID provides benefits over barcodes but also has limitations around cost and standardization.

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

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
