  2. 2. Contents Introduction of RFID Applications Survey Results Future development and opportunities 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 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
  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 ActiveTags • Use a battery • communicate over distances of several meters Semi-passiveTags • 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 • Derive their power from the field generated by the reader • without having an active transmitter to transfer the information stored PassiveTags

  9. 9. Applications Credit Cards with RFID (Paywave function) Octopus (Smart Card)
  10. 10. Applications Autotoll(Electronic toll collection) AccessControl
  11. 11. Online Survey  Target: SME  Information: Opinion on RFID and its applications  Site:  http://qtrial.qualtrics.com/SE/?SID=SV_9N5UPRZ uyuWtsk4
  12. 12. Survey Result Logistics andSupply ChainManagement 20% Pharmaceutic manufacturing industries 15% Library Management 21% Inventory Control 10% Document Management 8% Security 8% Customer Services 5% Hotel Management 5% Banking and Finance 5% Social Services 3% Other 18% Types of industries that respondentsthink it is possibleto apply RFID technology
  13. 13. Survey Result Only 6% is
  14. 14. Further Development  In medical uses and library management

  16. 16. 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
