  • 2. CONTENTS25/10/2012
  • 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 object25/10/2012
  • 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 system25/10/2012
  • 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 • Active25/10/2012
