  1. 1. RFIDApplication Tsoi Kiu Yau 12201952 10/16/2012
  2. 2. Contents FutureIntroduction Survey development Application Conclusion of RFID Results and opportunities
  3. 3. RFID• RFID = Radio Frequency Identification• Electronic labeling and wireless identification of objects using radio frequency• Tag carries with its information o a serial number o Model number o 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. 4. RFID components• A basic RFID system consists of these components: o 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 o A reader/antenna system to interrogate the RFID inlay o Application software and a host computer system
  5. 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 o Passive o Semi-passive o Active
  6. 6. Type of RFID Tags Active Tags Semi-passive Tags Passive Tags• Use a battery • Contain built-in • Derive their power• communicate over batteries to power from the field distances of several the chip’s generated by the meters circuitry, resist reader interference and • without having an circumvent a lack active transmitter of power from the to transfer the reader signal due to information stored long distance. • They are different from active tags in that they only transmit data at the time a response is received
  7. 7. Frequency of RFID tags in different 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 collection 5.8 Ghz) (Autotoll) (passive) • Container Tracking 20m – 40m (active)

  19. 19. Conclusion• Positive o RFID is a contactless reading technology and can read through other materials o Hold more data than barcode does o RFID tags data can be changed or added o More effective, bring lots of convenience to us• Negative o Cost is relatively remain high (compare to barcode) o RFID signals may have problems with some materials o RFID standards are still being developed
