RFIDRFID = Radio Frequency IdentificationElectronic labeling and wireless identification of objects using radio frequency Tag carries with its informationa serial numberModel 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

RFID componentsA 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

RFID TagThe 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 typesPassiveSemi-passiveActive
