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 a compatible reader, they transmit this information back to the reader, thereby identifying the object 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 RFIDinlay Application software and a host computer system 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 chipis transmitted by the antenna circuit embedded inthe RFID inlay via radio frequencies, to an RFIDreader 3 types Passive Semi-passive Active 6.
