Rfid application

  1. 1. Chan Tai Man Xxxxxxxx 24 July 2012
  2. 2. FutureIntroduction Survey development Applications Conclusion of RFID Results and opportunities
  3. 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. 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. 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. 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 • Without having an lack of power from active transmitter to the reader signal transfer the due to long distance information stored • They are different from active tags in that they only transmit data at the time a response is received

  11. 11.  Target: SME Information: Opinion on RFID and its applications Site:  http://qtrial.qualtrics.com/SE/?SID=SV_9N5UPRZ uyuWtsk4
  12. 12. Types of industries that respondents think it is possible to apply RFID technology Document Management 8% Inventory Control 10% Security Customer Services 8% 5%Library Management Hotel Management 21% Other 5% 18% Banking and Finance 5% Pharmaceutic manufacturing Social Services industries Logistics and Supply Chain 3% 15% Management 20%
  13. 13.  In medical uses and library management
  14. 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
