  • 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
  • Applications
  • Current Applications
  • Applications
    Credit Cards with RFID
    (Paywave function)
    Octopus (Smart Card)
  • Applications
    Autotoll (Electronic toll collection)
    Access Control
  • Online Survey
    Target: SME
    Information: Opinion on RFID and its applications

  • Survey Result
  • 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
