RFIDRFID = Radio Frequency IdentificationElectronic labeling and wireless identification of objectsusing radio frequencyTag carries with its information a serial number Model number Color or any other imaginable dataWhen these tags pass through a field generated by acompatible reader, they transmit this information back tothe 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 storage an antenna to facilitate communication with the RFID chipA reader/antenna system to interrogate the RFIDinlayApplication 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 istransmitted by the antenna circuit embedded in theRFID inlay via radio frequencies, to an RFID reader3 types Passive Semi-passive Active
Types of RFID Tags Active Tags Semi-passive Tags Passive Tags •Derive their power from the•Use a battery •Contain built-in batteries field generated by the•communicate over to power the chip’s reader distances of several meters circuitry, resist •without having an active interference and transmitter to transfer the circumvent a lack of information stored 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

ConclusionPositive RFID is a contactless reading technology and can read through other materials Hold more data than barcode does RFID tags data can be changed or added More effective, bring lots of convenience to usNegative Cost is relatively remain high (compare to barcode) RFID signals may have problems with some materials RFID standards are still being developed
