Rfid applications

  1. 1. 10/23/2012
  2. 2. FutureIntroduction development Applications Survey Results Conclusion of RFID and opportunities 10/23/2012
  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 object
  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 system
  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 › Active
  6. 6. 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 circuitry, generated by the meters resist interference reader and circumvent a • without having an lack of power from active transmitter to the reader signal transfer the 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. Frequency Appx. Read Data Speed Cost of Application Range 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) • Payment (paywave) LowUltra High 3m -7m Moderate to Low • Logistics and SupplyFrequency (433, High Chain (passive)868-928 Mhz) • Baggage TrackingMicrowave 10m -15m High High • Electronic toll(2.45 & 5.8 Ghz) collection (Autotoll) (passive) • Container Tracking 20m – 40m (active)

  12. 12. Types of industries that respondents think it is possible to apply RFID technology Document Management 8% Inventory Control 10% Security Customer Services 8% 5% Hotel ManagementLibrary Management Other 5% 21% 18% Banking and Finance 5% Pharmaceutic manufacturing industries Logistics and Supply Social Services 15% Chain Management 3% 20%
  13. 13.  In medical uses and library management
  14. 14.  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
