  3. 3. Introduction Project Detail Survey Result & Analysis Further information Conclusion
  4. 4.  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.  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.  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. Active Tags •Use a battery •communicate over distances of several meters Semi-passive Tags •Contain built-in batteries to power the chip’s circuitry, resist interference and circumvent a lack of power from the reader signal due to long distance. •They are different from active tags in that they only transmit data at the time a response is received Passive Tags •Derive their power from the field generated by the reader •without having an active transmitter to transfer the information stored
  8. 8. 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 Medi um 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 High High • Electronic toll collection (Autotoll) • Container Tracking

  16. 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
