  • 1. Operating SystemCHAN YIK MAN12206571 10/24/2012
  • 2. FutureIntroduction development Applications Survey Result Conclusion of OS and opportunities 10/24/2012
  • 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. 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. 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. 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. Applications
  • 8. Current Applications
  • 9. Credit Cards with RFID(Paywave function) Applications Octopus (Smart Card)
  • 10. Autotoll (Electronic toll collection) Applications Access Control
  • 11. Online Survey Target: SME Information: Opinion on RFID and its applications Site:  http://qtrial.qualtrics.com/SE/?SID=SV_9N5UPRZuyuWtsk4
  • 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. 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. Further Development In medical uses and library management
