  1. 1. The innovation of mobile phone Name: chan wui yan ID:12207217 10/24/12
  2. 2. 10/24/12
  3. 3. 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 objectRFID
  4. 4. 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 systemRFID components
  5. 5. 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 ◦ ActiveRFID Tag
  6. 6. Types of RFID Tags
  7. 7. Frequency Appx. Read Data Speed Cost Application Range of TagsLow Frequency <5cm Low High • Animal Identification(125kHz) (passive) • Access ControlHigh 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 SupplyFrequency High Chain(433, 868-928 (passive)Mhz) • Baggage TrackingMicrowave 10m -15m High High • Electronic toll(2.45 & 5.8 collection (Autotoll)Ghz) (passive) • Container Tracking 20m – 40m (active)Applications

  14. 14. Video
  15. 15. 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 someConclusion materials ◦ RFID standards are still being developed
