RFID 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, theytransmit this information back to the reader, 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 in athin film medium. Information stored in the memory of the RFID chip is transmitted bythe antenna circuit embedded in the RFID inlay via radio frequencies, toan RFID reader 3 types Passive Semi-passive Active 6. TYPES OF RFID TAGS Use a battery communicate over distances of several meters Active Tags Active TaPassive TagsgsActiveSemi-passive Tags Tags Derive their power from the field generated by the reader 1.Contain built-in batteries to power the chips without having an active circuitry, resist interferencetransmitter to transfer the and circumvent a lack ofinformation stored power from the reader signal due to long distance. 2.They are different from active tags in that they only transmit data at the time a response is received 7.
