RFID, or radio-frequency identification, is a technology that uses radio waves to electronically identify objects. An RFID tag contains information like a serial number that is transmitted to an RFID reader when passed through its field. The basic components of an RFID system are the tag/inlay containing a chip and antenna, a reader/antenna system, and application software. There are three main types of RFID tags: passive, semi-passive, and active. Current applications of RFID include credit cards, transit cards, electronic toll collection, access control, and uses in medical and libraries. While RFID offers benefits like contactless reading and updating of more data than barcodes, its costs remain relatively high and

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, they transmit this information back to the reader, thereby identifying the object RFID

4. 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 RFID components

5. 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 reader 3 types Passive Semi-passive Active RFID Tag

16. Positive 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 us Negative Cost is relatively remain high (compare to barcode) RFID signals may have problems with some materials RFID standards are still being developed Conclusion
