  • Cloudcomputing10/23/2012
  • FutureIntroduction development of cloud Applications Survey Result Conclusion and computing opportunities
  • 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
  • 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
  • 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
  • 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 the from the field distances of several chip’s circuitry, resist generated by the meters interference and reader circumvent a lack of •without having an 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
  • ApplicationsFrequency Appx.

  • Online Survey Target:SME Information: Opinion on RFID and its applications Site:  http://qtrial.qualtrics.com/SE/?SID=SV_9N5U PRZuyuWtsk4
  • 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% 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%
  • Further Development In medical uses and library management
  • Video
  • 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
