RFID RFID = Radio Frequency Identification Electronic labeling and wireless identification of objects usingradio 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 information back to thereader, 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 RFID inlay Application software and a host computer system 5. RFID Tag The RFID tag consists of an integrated circuit (IC) embedded ina thin film medium. Information stored in the memory of the RFID chip istransmitted by the antenna circuit embedded in the RFID inlayvia radio frequencies, to an RFID reader 3 types Passive Semi-passive Active 6. Types of RFID TagsActive TagsSemi-passive Tags Passive Tags Use a battery Contain built-in Derive their power communicate over batteries to power from the fielddistances of several the chips generated by themeters circuitry, resistreader interference and without having an circumvent a lack of active transmitter to power from the transfer the reader signal due to information stored long distance. They are different from active tags in that they only transmit data at the time a response is received 7. ApplicationsFrequency Appx. Read Data SpeedCost of ApplicationRangeTagsLow Frequency
