  2. 2. Workflow  FutureIntroduction Survey development Applications Conclusion of RFID Results and opportunities
  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 active transmitter to reader signal due to transfer the long distance. information stored • They are different from active tags in that they only transmit data at the time a response is received

  11. 11. ApplicationsFrequency  Appx. Read Range Data Speed Cost of Tags ApplicationLow 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)
  12. 12. Current Applications 
  13. 13. Credit Cards with RFID (Paywave function) Applications Octopus (Smart Card)
  14. 14. Autotoll (Electronic toll collection) Applications Access Control
  15. 15. Online Survey  Target: SME Information: Opinion on RFID and its applications Site:  http://qtrial.qualtrics.com/SE/?SID=SV_9N5UPRZuyu Wtsk4
  16. 16. 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%
  17. 17. Further Development  In medical uses and library management
  18. 18. Video 
  19. 19. 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
