- 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

- 7. APPLICATIONS Frequency Appx. Read Range Data Speed Cost of Tags Application Low Frequency (125kHz) <5cm (passive) Low High • Animal Identification • Access Control High Frequency (13.56 Mhz) 10 cm – 1m (passive) Low to Moderate Mediu m to Low • Smart Cards • Payment (paywave) Ultra High Frequency (433, 868-928 Mhz) 3m -7m (passive) Moderate to High Low • Logistics and Supply Chain • Baggage Tracking Microwave (2.45 & 5.8 Ghz) 10m -15m (passive) 20m – 40m (active) High High • Electronic toll collection (Autotoll) • Container Tracking

- 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
