Transcript

  • 1. Group members
  • 2. FutureIntroduction Survey development Applications Conclusion of RFID Results and opportunities
  • 3.  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.  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.  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. 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 lack •without having an of power from the active transmitter to reader signal due to transfer the long distance. information stored •They are different from active tags in that they only transmit data at the time a response is received

  • 12. Types of industries that respondents think it is possible to apply RFID technology Document Inventory Control Management 10% 8% Security 8% Customer Services 5%Library Management 21% Hotel Management 5% Other 18% Banking and Finance 5% Pharmaceutic manufacturing industries 15% Social Services 3% Logistics and Supply Chain Management 20%
  • 13.  In medical uses and library management
  • 14.  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
