  1. 1. SOLAR CELL LEUNG Kwai Sum 12205397 22 October 2012
  2. 2. CONTENTS
  3. 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. 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. 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. 6. TYPES OF RFID TAGS
  7. 7. APPLICATIONSFrequency Appx. Read Data Speed Cost of Tags Application RangeLow Frequency (125kHz) <5cm Low High • Animal Identification (passive) • Access ControlHigh Frequency (13.56 Mhz) 10 cm – 1m Low to Moderate Medium to Low • Smart Cards (passive) • Payment (paywave)Ultra High Frequency (433, 868-928 3m -7m Moderate to High Low • Logistics and Supply ChainMhz) (passive) • Baggage TrackingMicrowave (2.45 & 5.8 Ghz) 10m -15m High High • Electronic toll collection (Autotoll) (passive) • Container Tracking 20m – 40m (active)

  11. 11. ONLINE SURVEY Target: SME Information: Opinion on RFID and its applications Site:  http://qtrial.qualtrics.com/SE/?SID=SV_9N5UPR ZuyuWtsk4
  12. 12. SURVEY RESULT 43.5 32.5 2 Manufacturing 1.5 Retailing Transportation 1 Warehousing 0.5 0 Enhanced customer Improved satisfaction efficiency Increased inventory Reduced turnover rate manpower Reduced total cost
  13. 13. FURTHER DEVELOPMENT In medical uses and library management
  14. 14. VIDEO
  15. 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
