  1. 1. Chau Hoi Ying 1221321723 October 2012
  2. 2. Contents  Future Introduction Survey development Applications Conclusion of RFID Results and opportunities23 October 2012
  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• communicate over batteries to power the from the field distances of several chip’s circuitry, resist generated by the meters interference and reader circumvent a lack of • without having an power from the reader active transmitter to signal due to long transfer the distance. information stored • They are different from active tags in that they only transmit data at the time a response is received
  7. 7. ApplicationsFrequency  Appx. Read Range Data Speed Cost of Application TagsLow Frequency <5cm Low High • Animal Identification(125kHz) (passive) • Access ControlHigh Frequency (13.56 10 cm – 1m Low to Moderate Medium • Smart CardsMhz) to Low (passive) • Payment (paywave)Ultra High Frequency 3m -7m Moderate to High Low • Logistics and Supply Chain(433, 868-928 Mhz) (passive) • Baggage TrackingMicrowave (2.45 & 5.8 10m -15m High High • Electronic toll collection (Autotoll)Ghz) (passive) • Container Tracking 20m – 40m (active)
  8. 8. Current Applications Application Segment Representative Applications Competitive Technologies Current Penetration Typical Tag TypeAccess Control Doorway entry Other keyless entry High Passive technologiesAsset Tracking Locating tractors within a None Low Active freight yardAsset Tagging Tracking corporate Bar Code Low Passive computing systemsAuthentication Luxury goods counterfeit Holograms Low Passive preventionBaggage Tracking Positive bag matching Bar Code, Optical Character Low Passive RecognitionPOS Applications SpeedPass Credit Cards, Smart Cards, Medium Passive Wireless PhonesSCM (Container Level) Tracking containers in GPS-based Systems Low Active shipping terminalsSCM (Pallet Level) Tracking palletized Bar Code Minimal Active, Passive shipmentsSCM (Item Level) Identifying individual Bar Code Minimal Passive itemsVehicle Identification Electronic toll collection Bar Code, License plate, Medium Active, Passive reader systemsVehicle Immobilizers Automotive ignition Other theft prevention High Passive systems technologies
  9. 9. Credit Cards with RFID (Paywave function) Applications Octopus (Smart Card)
  10. 10. Autotoll (Electronic toll collection) Applications Access Control
  11. 11. Online Survey  Target: SME Information: Opinion on RFID and its applications Site:  http://qtrial.qualtrics.com/SE/?SID=SV_9N5UPRZuyuWtsk 4
  12. 12. Survey Result  Types of industries that respondents think it is possible to apply RFID technology Document Inventory Control Management 10% 8% Security 8% Customer Services 5%Library Management Hotel Management 21% 5% Other 18% Banking and Finance Pharmaceutic manufacturing 5% industries 15% Social Services 3% Logistics and Supply Chain 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
