3. 3. * 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. 4. * A basic RFID system consists of these components:* A programmable RFID tag/inlay for storing itemdata; * 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 chipis transmitted by the antenna circuit embedded inthe RFID inlay via radio frequencies, to an RFIDreader* 3 types* Passive* Semi-passive* Active*
