  1. 1. RFID Application 杨旻 12250546 刘家华 12251496Sunday, October 21, 2012
  2. 2. Workflow FutureIntroduction Survey development Application Conclusion of RFID Result and opportunities
  3. 3. 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
  4. 4. 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
  5. 5. 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
  6. 6. 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 from the field distances of several the chip’s circuitry, generated by the meters resist interference reader and circumvent a • without having an lack of power from active transmitter to the reader signal transfer the due to long information stored distance. • They are different from active tags in that they only transmit data at the time a response is received
