This document discusses RFID (radio frequency identification) technology. It describes RFID as electronic labeling that uses radio waves to identify objects through tags attached to or embedded in them. The tags contain information like a serial number that is transmitted to an RFID reader when passed through its field. The document outlines the basic components of an RFID system including RFID tags, readers, and host computers. It also describes the different types of RFID tags and provides examples of current RFID applications like credit cards, transportation payment cards, electronic toll collection, and access control.

3. 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

4. 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 chip A reader/antenna system to interrogate the RFID inlay Application software and a host computer system

5. 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

15. ConclusionPositiveRFID is a contactless reading technology and can read through other materialsHold more data than barcode doesRFID tags data can be changed or addedMore effective, bring lots of convenience to usNegativeCost is relatively remain high (compare to barcode)RFID signals may have problems with some materialsRFID standards are still being developed
