  1. 1. RFID APPLICATION 10/24/2012
  2. 2. Introduction Survey Future Application Conclusion of RFID Results developmentWorkflow
  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 objectRFID
  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 systemRFID components
  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 • ActiveRFID Tag
  6. 6. 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 Types of RFID Tags
  7. 7. Frequency Appx. Read Data Speed Cost of Application Range Tags Low Frequency <5cm Low High • Animal Identification (125kHz) (passive) • Access Control High 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 Chain Frequency (433, 868-928 Mhz) (passive) • Baggage Tracking Microwave (2.45 & 10m -15m High High • Electronic toll collection 5.8 Ghz) (Autotoll) (passive) • Container Tracking 20m – 40m (active)Applications

  11. 11. • Target: SME• Information: Opinion on RFID and its applications• Site: • http://qtrial.qualtrics.com/SE/?SID=SV_9N5UPRZuyuWtsk 4Online Survey
  12. 12. Types of industries that respondents think it is possible to apply RFID technology Document Inventory Control Management 10% 8% Security 8% Customer Services 5% Library Management Hotel Management 21% 5% Other 18% Banking and Finance 5% Pharmaceutic manufacturing industries 15% Social Services 3% Logistics and Supply Chain Management 20%Survey Result
  13. 13. • In medical uses and library managementFurther Development
  14. 14. Video
  15. 15. • 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) Conclusion • RFID signals may have problems with some materials • RFID standards are still being developed
