  1. 1. RFID Application Chung Hiu Ngan 13213792 11 Oct 2013
  2. 2. Introduction of RFID Future development and opportunities Content Applications Conclusion Survey Results
  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 RFID
  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 RFID components
  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 RFID Tag
  6. 6. Active Tags • Use a battery • communicate over distances of several meters Semi-passive Tags Passive Tags • 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 Types of RFID Tags

  11. 11.  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 Conclusion
