  2. 2.  Introduction of RFID Application Survey Results Future development and opportunities Conclusion
  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 •Use a battery •communicate over distances of several meters Semi-passive Tags 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 •Derive their power from the field generated by the reader •without having an active transmitter to transfer the information stored
  7. 7. Applications  Frequency of RFID tags in different applications Frequency Low Frequency (125kHz) High Frequency (13.56 Mhz) Ultra High Frequency (433, 868-928 Mhz) Appx. Read Range <5cm (passive) 10 cm – 1m (passive) 3m -7m (passive) Microwave (2.45 & 10m -15m 5.8 Ghz) (passive) 20m – 40m (active) Data Speed Low Low to Moderate Moderate to High High Cost of Tags High Mediu m to Low Low High Application • Animal Identification • • Access Control Smart Cards • Payment (paywave) • Logistics and Supply Chain • • Baggage Tracking Electronic toll collection (Autotoll) • Container Tracking
  8. 8. Current Applications  Competitive Technologies Other keyless entry technologies None Current Penetration High Typical Tag Type Low Active Access Control Doorway entry Asset Tracking Locating tractors within a freight yard Asset Tagging Tracking corporate computing systems Bar Code Low Passive Authentication Luxury goods counterfeit prevention Positive bag matching Holograms Low Passive Bar Code, Optical Character Recognition Low Passive POS Applications SpeedPass Credit Cards, Smart Cards, Wireless Phones Medium Passive SCM (Container Level) Tracking containers in shipping terminals GPS-based Systems Low Active SCM (Pallet Level) Tracking palletized shipments Bar Code Minimal Active, Passive SCM (Item Level) Identifying individual items Electronic toll collection Bar Code Minimal Passive Bar Code, License plate, reader systems Medium Active, Passive Automotive ignition systems Other theft prevention technologies High Passive Baggage Tracking Vehicle Identification Vehicle Immobilizers Passive

  10. 10. Autotoll (Electronic toll collection) Applications Access Control
  11. 11. Online Survey   Target: SME  Information: Opinion on RFID and its applications  Site:  yuWtsk4
  12. 12. Survey Result  Benefits of using RFID in different industries Manufacturing Retailing 4 Transportation Warehousing 4 4 4 3 3 2 2 2 1 1 1 1 0 1 0 0 Enhanced customer satisfaction 0 Improved efficiency Increased inventory turnover rate 0 0 Reduced manpower Reduced total cost
  13. 13. Further Development   In medical uses and library management
  14. 14. Video 
  15. 15. Conclusion  Positive  technology and can read  RFID is a contactless reading 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
