  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 istransmitted by the antenna circuit embedded in theRFID inlay via radio frequencies, to an RFID reader3 types Passive Semi-passive Active

  13. 13.  In medical uses and library management
  14. 14.  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 developed10/25/2012
