  2. 2. Introduction Survey result Conclusion
  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. Credit Cards with RFID (Paywave function) Applications Octopus (Smart Card)
  7. 7. Autotoll (Electronic toll collection) Applications Access Control
  8. 8.    Target: SME Information: Opinion on RFID and its applications Site: ◦ http://qtrial.qualtrics.com/SE/?SID=SV_9N5UPRZuy uWtsk4
  9. 9.  In medical uses and library management
  10. 10.  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
