RFID Application

  1. 1. Siu Wing Sum 13212990 Monday, October 07, 2013
  2. 2. Introduction of RFID Applications Survey Results Future Development and Opportunities 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. Active Tags •Use a battery •communicate over distances of several meters Semi-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 Passive Tags •Derive their power from the field generated by the reader •without having an active transmitter to transfer the information stored

  11. 11.  In medical uses and library management
  12. 12.  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
