2. FutureSurveyDevelopmentIntroduction Applications ConclusionResults andOpportunities 3. RFID = Radio FrequencyIdentification Electronic labeling and wirelessidentification of objects using radiofrequency Tag carries with its information a serial number Model number Color or any other imaginable data When these tags pass through afield generated by a compatiblereader, they transmit thisinformation back to the reader,thereby identifying the object 4. A basic RFID system consists ofthese components: A programmable RFID tag/inlay for storingitem data; Consisting of an RFID chip for data storage an antenna to facilitate communication with the RFID chip A reader/antenna system tointerrogate the RFID inlay Application software and a hostcomputer system 5. The RFID tag consists of anintegrated circuit (IC) embedded ina thin film medium. Information stored in the memoryof the RFID chip is transmitted bythe antenna circuit embedded inthe RFID inlay via radiofrequencies, to an RFID reader 3 types Passive Semi-passive Active 6. Active Tags Semi-passive TagsPassive Tags Use a battery Contain built-in Derive their power communicate over batteries to powerfrom the fielddistances of several the chips circuitry, generated by themeters resist interference reader and circumvent a lack without having an of power from the active transmitter to reader signal due totransfer the long distance.information stored They are different from active tags in that they only transmit data at the time a response is received 7.
