  3. 3. PRESENTATION FLOW
  4. 4. 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
  5. 5. 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
  6. 6. 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. 7.  TYPES OF RFID TAGS
  8. 8. 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

  17. 17. 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
