  1. 1. 2D code Chim Hiu Chau 13209833 October 16, 2013
  2. 2. Contents Introduction of 2D code application Survey result Future development and opportunity Conclusion
  3. 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. 4. Rfid component  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. 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. 6. Types of RFID Tags Active Tags •Use a battery •communicate over distances of several meters Semi-passive Tags •Contain built-in batteries to power the chip’s circuitry, resist interference and 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 •Derive their power from the field generated by the reader •without having an active transmitter to transfer the information stored
  7. 7. Applications Frequency Low Frequency (125kHz) Appx. Read Range <5cm High Frequency (13.56 Mhz) (passive) 10 cm – 1m Microwave (2.45 & 5.8 Ghz) (passive) 10m -15m Cost of Tags Application Low High • Animal Identification • • Access Control Smart Cards • • Payment (paywave) Logistics and Supply Chain • Ultra High Frequency (433, 868928 Mhz) (passive) 3m -7m Data Speed Baggage Tracking • Electronic toll collection (Autotoll) • Container Tracking Low to Moderate Medium to Low Moderate to High Low High High (passive) 20m – 40m (active)
  8. 8. Current Applications Application Segment Representative Applications Access Control Doorway entry Asset Tracking Competitive Technologies Other keyless entry technologies Locating tractors within a freight yard None Current Penetration High Typical Tag Type Passive Low Active Asset Tagging Tracking corporate computing systems Bar Code Low Passive Authentication Luxury goods counterfeit prevention Holograms Low Passive Baggage Tracking Positive bag matching Bar Code, Optical Character Recognition Low Passive POS Applications SpeedPass Credit Cards, Smart Cards, Wireless Phones Medium Passive SCM (Container Level) Tracking containers in shipping terminals GPS-based Systems Low Active 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 systems Medium Active, Passive Vehicle Immobilizers Automotive ignition systems Other theft prevention technologies High Passive
  9. 9. Survey result Types of industries that respondents think it is possible to apply RFID technology Document Management 8% Inventory Control 10% Security 8% Library Management 21% Customer Services 5% Other 18% Hotel Management 5% Banking and Finance 5% Pharmaceutic manufacturing industries 15% Logistics and Supply Chain Management 20% Social Services 3%
  10. 10. Further Development In medical uses and library management

  12. 12. 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
