  • 1. RFID ApplicationLoree Ng 2012/10/30Student No: 1220300
  • 2. Contents FutureIntroduction Survey development Applications Conclusion of RFID Results and opportunities
  • 3. RFID• 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. 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 chip ▫ A reader/antenna system to interrogate the RFID inlay ▫ Application software and a host computer system
  • 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 ▫ Passive ▫ Semi-passive ▫ Active
  • 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 meters interference and reader circumvent a lack of • without having an power from the active transmitter to reader signal due to transfer the long distance. information stored • They are different from active tags in that they only transmit data at the time a response is received
  • 7. ApplicationsFrequency Appx. Read Range Data Speed Cost of Tags ApplicationLow Frequency <5cm Low High • Animal(125kHz) Identification (passive) • Access ControlHigh Frequency (13.56 10 cm – 1m Low to Moderate Medium to Low • Smart CardsMhz) (passive) • Payment (paywave)Ultra High Frequency 3m -7m Moderate to High Low • Logistics and(433, 868-928 Mhz) Supply Chain (passive) • Baggage TrackingMicrowave (2.45 & 5.8 10m -15m High High • Electronic tollGhz) collection (passive) (Autotoll) 20m – 40m • Container (active) Tracking

  • 10. Applications• Autotoll (Electronic toll collection) Access Control
  • 11. Online Survey• Target: SME• Information: Opinion on RFID and its applications• Site: ▫ http://qtrial.qualtrics.com/SE/?SID=SV_9N5UP RZuyuWtsk4
  • 12. Benefits of using RFID in different industries Manufacturing Retailing Transportation Warehousing 4 4 4 4 3 3 2 2 2 1 1 1 1 1 0 0 0 0Enhanced customer satisfaction Improved efficiency 0 0 Increased inventory turnover rate Reduced manpower Reduced total cost
  • 13. Further Development• In medical uses and library management
  • 14. Video
  • 15. Conclusion• 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
