  1. 1. RFID Application Chan Tai Man xxxxxxxx 3 March 2013
  2. 2. Contents FutureIntroduction Survey development Applications Conclusion of RFID Results and opportunities
  3. 3. RFIDRFID = Radio Frequency IdentificationElectronic labeling and wireless identification of objectsusing radio frequencyTag carries with its information a serial number Model number Color or any other imaginable dataWhen these tags pass through a field generated by acompatible reader, they transmit this information back tothe reader, thereby identifying the object
  4. 4. RFID componentsA 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 TagThe RFID tag consists of an integrated circuit (IC)embedded in a thin film medium.Information stored in the memory of the RFID chip istransmitted by the antenna circuit embedded in theRFID inlay via radio frequencies, to an RFID reader3 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 from the field distances of several the chip’s generated by the meters circuitry, resist reader interference and •without having an circumvent a lack of active transmitter to power from the transfer the reader signal due to information stored long distance. •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 Tags ApplicationLow Frequency (125kHz) <5cm Low High • Animal Identification (passive) • Access ControlHigh Frequency (13.56 Mhz) 10 cm – 1m Low to Moderate Medium to Low • Smart Cards (passive) • Payment (paywave)Ultra High Frequency (433, 868-928 Mhz) 3m -7m Moderate to High Low • Logistics and Supply Chain (passive) • Baggage TrackingMicrowave (2.45 & 5.8 Ghz) 10m -15m High High • Electronic toll collection (Autotoll) (passive) • Container Tracking 20m – 40m (active)
  8. 8. Current Applications
  9. 9. ApplicationsCredit Cards with RFID(Paywave function) Octopus (Smart Card)
  10. 10. ApplicationsAutotoll (Electronic toll collection) Access Control
  11. 11. Online SurveyTarget: SMEInformation: Opinion on RFID and its applicationsSite: http://qtrial.qualtrics.com/SE/?SID=SV_9N5UPRZuyuWts k4
  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% Pharmaceutic Banking and Finance manufacturing industries 5% 15% Social Services Logistics and Supply Chain 3% Management 20%
  13. 13. Further DevelopmentIn medical uses and library management
  14. 14. Video
  15. 15. ConclusionPositive 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 usNegative Cost is relatively remain high (compare to barcode) RFID signals may have problems with some materials RFID standards are still being developed
