RFID technologies allow for the electronic identification of objects using radio frequency tags. An RFID system consists of RFID tags which contain identifying information, a reader to interrogate the tags, and application software. RFID tags come in three types - passive, semi-passive, and active - and contain an integrated circuit and antenna. Current applications of RFID include credit cards, smart cards, electronic toll collection, access control, and supply chain management. While RFID provides benefits like contactless reading and storing more data, limitations include relatively high costs and interoperability issues due to developing standards.

3. RFID 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

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 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 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 reader 3 types Passive Semi-passive Active

15. Conclusion 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
