  1. 1. RFID Application 10/18/2012
  2. 2. WorkflowIntroduction Future Applications Survey Results Conclusion of RFID development 10/18/2012
  3. 3. Types of RFID Tags Passive TagsActive Tags Semi-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 active transmitter of power from the to transfer the reader signal due information stored to long distance. •They are different from active tags in that they only transmit data at the time a response is received 10/18/2012
  4. 4. 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 Mediu • Smart Cards(13.56 Mhz) Moderate m to (passive) Low • Payment (paywave)Ultra High 3m -7m Moderate to Low • Logistics and SupplyFrequency (433, High Chain868-928 Mhz) (passive) • Baggage TrackingMicrowave (2.45 & 10m -15m High High • Electronic toll collection5.8 Ghz) (Autotoll) (passive) • Container Tracking 20m – 40m (active) 10/18/2012
  5. 5. RFID• RFID = Radio Frequency Identification• Electronic labeling and wireless identification of objects using radio frequency• Tag carries with its information o a serial number o Model number o 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
  6. 6. RFID components• A basic RFID system consists of these components: o 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
  7. 7. 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 o Passive o Semi-passive o Active
  8. 8. Applications
  9. 9. ApplicationsCredit Cards with RFID (Paywave function) Octopus (Smart Card)
  10. 10. ApplicationsAutotoll (Electronic toll collection) Access Control
  11. 11. Online Survey• Target: SME• Information: Opinion on RFID and its applications• Site: o http://qtrial.qualtrics.com/SE/?SID=SV_9N5UPRZuyuWtsk4
  12. 12. Survey Result
  13. 13. Further Development• In medical uses and library management
  14. 14. Video
  15. 15. Conclusion• Positive o RFID is a contactless reading technology and can read through other materials o Hold more data than barcode does o RFID tags data can be changed or added o More effective, bring lots of convenience to us• Negative o Cost is relatively remain high (compare to barcode) o RFID signals may have problems with some materials o RFID standards are still being developed
