5. 5. RFID RFID = Radio Frequency Identification Electronic labeling and wireless identification ofobjects 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 acompatible reader, they transmit this informationback to the reader, thereby identifying the object
6. 6. 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 RFIDinlay Application software and a host computer system
7. 7. 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 istransmitted by the antenna circuit embedded in theRFID inlay via radio frequencies, to an RFID reader 3 types Passive Semi-passive Active
