  • 1. RFID APPLICATION Name: Zhao Meng Meng ID: 12251011 10/23/2012
  • 2. 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, theytransmit 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 athin film medium. Information stored in the memory of the RFID chip is transmitted bythe antenna circuit embedded in the RFID inlay via radio frequencies, toan RFID reader 3 types • Passive • Semi-passive • Active
  • 6. TYPES OF RFID TAGS • Use a battery • communicate over distances of several meters Active Tags Active TaPassive Tagsgs ActiveSemi-passive Tags Tags • Derive their power from the field generated by the reader • 1. Contain built-in batteries to power the chip’s • without having an active circuitry, resist interference transmitter to transfer the and circumvent a lack of information stored power from the reader signal due to long distance. • 2. They are different from active tags in that they only transmit data at the time a response is received
  • 7. APPLICATIONSFrequency 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 Moderate Medium • Smart Cards(13.56 Mhz) to Low (passive) • Payment (paywave)Ultra High 3m -7m Moderate to High Low • Logistics and Supply ChainFrequency (433,868-928 Mhz) (passive) • Baggage TrackingMicrowave (2.45 & 10m -15m High High • Electronic toll collection5.8 Ghz) (Autotoll) (passive) • Container Tracking 20m – 40m (active)

  • 11. ONLINE SURVEY Target: SME Information: Opinion on RFID and its applications Site: • http://qtrial.qualtrics.com/SE/?SID=SV_9N5UPRZuyuWtsk4
  • 12. SURVEY RESULT Types of industries that respondents think it is possible to apply RFID technology Document Management 8% Inventory Control 10% Security Customer Services 8% 5%Library Management Hotel Management 21% Other 5% 18% Banking and Finance 5% Pharmaceutic manufacturing Social Services industries Logistics and Supply Chain 3% 15% Management 20%
  • 13. FURTHER DEVELOPMENT In medical uses and library management

  • 15.  Positive CONCLUSION • 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
