  2. 2. WorkflowIntroduction Application Future Survey Results conclusion of RFID development
  3. 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. 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. 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. 6. Types of RFID Tags Active Tags Semi-passive Tags Passive Tags• Use a battery •Contain built-in •Derive their power batteries to power the from the field• communicate chip’s circuitry, resist generated by the over distances of interference and reader several meters circumvent a lack of •without having an power from the reader signal due to active transmitter to long distance. transfer the •They are different information stored from active tags in that they only transmit data at the time a response is received
  7. 7. ApplicationsFrequency Appx. Read Data Speed Cost of Application Range TagsLow Frequency <5cm Low High • Animal Identification(125kHz) (passive) • Access ControlHigh Frequency 10 cm – 1m Low to Mediu • Smart Cards(13.56 Mhz) Moderate m to (passive) Low • Payment (paywave)Ultra High 3m -7m Moderate to Low • Logistics and SupplyFrequency (433, High Chain868-928 Mhz) (passive) • Baggage TrackingMicrowave (2.45 10m -15m High High • Electronic toll& 5.8 Ghz) collection (Autotoll) (passive) • Container Tracking 20m – 40m (active)

  11. 11. Online Survey Target:SME Information: Opinion on RFID and its applications Site:  http://qtrial.qualtrics.com/SE/?SID=SV_9N5U PRZuyuWtsk4
  12. 12. Survey Result Types of industries that respondents think it is possible to apply RFID technology Document Management 8% Inventory Control 10% Security Customer Services 8% 5% Library Management Hotel Management 21% Other 5% 18% Banking and Finance 5% Pharmaceutic manufacturing Social Services industries Logistics and Supply Chain 3% 15% Management 20%
  13. 13. Further Development In medical uses and library management
  14. 14. Video
  15. 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
