Transcript

  • 1. RFID Applications Wong Yan Ki 1220650410/18/2012
  • 2. Work flowIntroduction Future of RFID Applications Survey Results Conclusion development technology
  • 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
  • 6. Types of RFID Tags Derive their power from Active Tags Semi-passive Tags the field generated by the reader•Use a battery •Contain built-in •without having an•communicate over batteries to power the active transmitter to distances of several chip’s circuitry, resist transfer the meters interference and information stored 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 •Passive Tags
  • 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 Moderate Medium • Smart Cards(13.56 Mhz) 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 & 10m -15m High High • Electronic toll collection5.8 Ghz) (Autotoll) (passive) • Container Tracking 20m – 40m (active)
  • 8.

  • 9. ApplicationsCredit Cards with RFID(Paywave function) Octopus (Smart Card)
  • 10. Applications Access ControlAutotoll (Electronic toll collection)
  • 11. Online Survey Target:SME Information: Opinion on RFID and its applications Site:  http://qtrial.qualtrics.com/SE/?SID=SV_9N5U PRZuyuWtsk4
  • 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% Pharmaceutic Banking and Finance manufacturing 5% industries 15% Social Services Logistics and Supply Chain 3% Management 20%
  • 13. Further Development In medical uses and library management
  • 14. Video
  • 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
