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