  • 10/18/2012 FutureIntroduction Development Application Survey results Conclusion of RFID and opportunities
  • 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
  • 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
  • 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
  • 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 circuitry, generated by the meters resist interference reader and circumvent a •without having an lack of power from active transmitter to the reader signal due transfer the to long distance. information stored •They are different from active tags in that they only transmit data at the time a response is received
  • 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 Medium • Smart Cards(13.56 Mhz) Moderate to Low (passive) • Payment (paywave)Ultra High 3m -7m Moderate to Low • Logistics and Supply ChainFrequency (433, High868-928 Mhz) (passive) • Baggage TrackingMicrowave (2.45 & 10m -15m High High • Electronic toll collection5.8 Ghz) (Autotoll) (passive) • Container Tracking 20m – 40m (active)
  • Current Applications Application Segment Representative Applications Competitive Technologies Current Penetration Typical Tag Type Access Control Doorway entry Other keyless entry technologies High Passive Asset Tracking Locating tractors within a None Low Active freight yard Asset Tagging Tracking corporate Bar Code Low Passive computing systems Authentication Luxury goods counterfeit Holograms Low Passive prevention Baggage Tracking Positive bag matching Bar Code, Optical Character Low Passive Recognition POS Applications SpeedPass Credit Cards, Smart Cards, Medium Passive Wireless Phones SCM (Container Level) Tracking containers in GPS-based Systems Low Active shipping terminals SCM (Pallet Level) Tracking palletized shipments Bar Code Minimal Active, Passive SCM (Item Level) Identifying individual items Bar Code Minimal Passive Vehicle Identification Electronic toll collection Bar Code, License plate, reader Medium Active, Passive systems Vehicle Immobilizers Automotive ignition systems Other theft prevention High Passive technologies
  • Credit Cards with RFID(Paywave function) Applications Octopus (Smart Card)
  • Autotoll (Electronic toll collection) Applications Access Control
  • Online Survey Target:SME Information: Opinion on RFID and its applications Site:  http://qtrial.qualtrics.com/SE/?SID=SV_9N5U PRZuyuWtsk4
  • Survey Result Benefits of using RFID in different industries Increased inventory turnover rate 0% Reduced manpower 40% Improved Other efficiency 60% 40% Enhanced customer satisfaction 0% Reduced total cost 20%
  • Further Development In medical uses and library management
  • Video
  • 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
