3. RFID = Radio Frequency Identification Electronic labeling and wireless identification of 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 field generated by a compatible reader, they transmit this information back to the reader, thereby identifying the objectRFID

4. 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 systemRFID components

5. The RFID tag consists of an integrated circuit (IC) embedded in a thin film medium. Information stored in the memory of the RFID chip is transmitted by the antenna circuit embedded in the RFID inlay via radio frequencies, to an RFID reader 3 types Passive Semi-passive ActiveRFID Tag

6. Active Tags Semi-passive Tags Passive Tags Use a battery Contain built-in Derive their power communicate over batteries to power from the field distances of several the chips generated by the meters circuitry, resist reader 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 Types of RFID Tags
