RFID application

  1. 1. Cheung Ki Yan 13214993 15 October 2013
  2. 2.    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
  3. 3.  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
  4. 4.    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
  5. 5. Frequency Data Speed Cost of Tags Application Low Frequency <5cm (125kHz) (passive) Low High • Animal Identification • Access Control High Frequency 10 cm – 1m (13.56 Mhz) (passive) Low to Moderate Medium to Low • Smart Cards • Payment (paywave) Moderate to High Low • Logistics and Supply Chain • Baggage Tracking • Electronic toll collection (Autotoll) • Container Tracking Ultra High Frequency (433, 868-928 Mhz) Microwave (2.45 & 5.8 Ghz) Appx. Read Range 3m -7m (passive) 10m -15m High High (passive) 20m – 40m (active)
  6. 6. Application Segment Representative Applications Competitive Technologies Doorway entry Other keyless entry Access Control Asset Tracking Asset Tagging Locating tractors within a freight yard Tracking corporate computing systems Current Penetration Typical Tag Type High Passive technologies None Low Active Bar Code Low Passive Low Passive Authentication Luxury goods counterfeit prevention Holograms Baggage Tracking Positive bag matching POS Applications SpeedPass SCM (Container Level) Tracking containers in shipping terminals SCM (Pallet Level) SCM (Item Level) Bar Code, Optical Low Character Recognition Credit Cards, Smart Medium Cards, Wireless Phones GPS-based Systems Low Passive Tracking palletized shipments Bar Code Minimal Active, Passive Identifying individual items Bar Code Minimal Passive Passive Active Vehicle Identification Electronic toll collection Bar Code, License plate, Medium reader systems Active, Passive Vehicle Immobilizers Automotive ignition systems Other theft prevention technologies Passive High
  7. 7. Applications Credit Cards with RFID (Paywave function) Octopus (Smart Card)
  8. 8. Applications Autotoll (Electronic toll collection) Access Control
  9. 9.    Target: SME Information: Opinion on RFID and its applications Site:  http://qtrial.qualtrics.com/SE/?SID=SV_9N5UP RZuyuWtsk4
  10. 10. Types of industries that respondents think it is possible to apply RFID technology Document Management 8% Inventory Control 10% Library Management 21% Pharmaceutic manufacturing industries 15% Security 8% Others 18% Customer Services 5% Hotel Management 5% Banking and Finance 5% Logistics and Supply Chain Management 20% Social Services 3%
  11. 11.  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
