    • Applications
      10/12/2011
    • 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

    • 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
