  1. 1. Operating SystemCHAN YIK MAN12206571 10/24/2012
  2. 2. FutureIntroduction development Applications Survey Result Conclusion of OS and opportunities 10/24/2012
  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 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 generated by the meters circuitry, resist reader interference and • without having an circumvent a lack of active transmitter to power from the transfer the reader signal due to information stored long distance. • They are different from active tags in that they only transmit data at the time a response is received
  7. 7. Applications
  8. 8. Current Applications
  9. 9. Credit Cards with RFID(Paywave function) Applications Octopus (Smart Card)
  10. 10. Autotoll (Electronic toll collection) Applications Access Control
  11. 11. Online Survey Target: SME Information: Opinion on RFID and its applications Site:  http://qtrial.qualtrics.com/SE/?SID=SV_9N5UPRZuyuWtsk4
  12. 12. Survey Result Types of industries that respondents think it is possible to apply RFID technology Document Management 8% Inventory Control 10% Security Customer Services 8% 5% Hotel ManagementLibrary Management Other 5% 21% 18% Banking and Finance Pharmaceutic 5% manufacturing industries Logistics and Supply Social Services 15% Chain Management 3% 20%
  13. 13. 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
  14. 14. Further Development In medical uses and library management
