2. FutureIntroduction development of RFID Applications Survey results Conclusion andApplications opportunities 3. RFID = Radio Frequency Identification Electronic labeling and wireless identificationof 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 fieldgenerated by a compatible reader, theytransmit this information back to thereader, thereby identifying the object 4. A basic RFID system consists of thesecomponents: 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 theRFID inlay Application software and a host computersystem 5. The RFID tag consists of an integrated circuit(IC) embedded in a thin film medium. Information stored in the memory of the RFIDchip is transmitted by the antenna circuitembedded in the RFID inlay via radiofrequencies, to an RFID reader 3 types Passive Semi-passive Active 6.
