  1. 1. 10/16/2012PROJECT TOPIC:Name : YIP MEI YU
  2. 2. 10/16/2012 RFID FutureIntroduction Survey development Applications conclusion of RFID Results and opportunity
  3. 3. RFID RFID = Radio Frequency IdentificationElectronic 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. 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 chipA reader/antenna system to interrogate the RFID inlay 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 theantenna circuit embedded in the RFID inlay via radio frequencies, to an RFID reader 3 types Passive Semi-passive Active
  6. 6. TYPES OF RFID TAGS Active Tags Semi-passive Tags Passive Tags• Use a battery • Contain built-in • Derive their power• communicate over batteries to power the from the field distances of several chip’s circuitry, resist generated by the reader meters interference and • without having an circumvent a lack of active transmitter to power from the reader transfer the signal due to long information stored distance. • They are different from active tags in that they only transmit data at the time a response is received
  7. 7. APPLICATIONSFrequency Appx. Read Range Data Speed Cost of Application TagsLow Frequency <5cm Low High • Animal Identification(125kHz) (passive) • Access ControlHigh Frequency (13.56 10 cm – 1m Low to Moderate Medium • Smart CardsMhz) to Low (passive) • Payment (paywave)Ultra High Frequency 3m -7m Moderate to High Low • Logistics and Supply Chain(433, 868-928 Mhz) (passive) • Baggage TrackingMicrowave (2.45 & 5.8 10m -15m High High • Electronic toll collectionGhz) (Autotoll) (passive) • Container Tracking 20m – 40m (active)

  15. 15. CONCLUSION PositiveRFID 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
