RFIDRFID = Radio Frequency IdentificationElectronic labeling and wireless identification of objects using radio frequencyTag carries with its information Model numbera serial numberColor or any other imaginable dataWhen these tags pass through a field generated by a compatible reader, they transmit 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 storagean antenna to facilitate communication with the RFID chipA reader/antenna system to interrogate the RFID inlayApplication software and a host computer system 5. RFID Tag 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 reader3 types PassiveSemi-passiveActive 6. Types of RFID TagsActive Tags Use a battery communicate over distances of several metersSemi-passive TagsPassive Tags Contain built-in batteries to power the chips circuitry, resist interference and circumvent a lack of power from the reader signal due to long distance. They are different from active tags in that they only transmit data at the time a response is received Derive their power from the field generated by the reader without having an active transmitter to transfer the information stored 7.
