  1. 1. Survey result Introduction Future application development conclusion of RFID and opportunities2012/10/26
  2. 2. + 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
  3. 3. + 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
  4. 4. + 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
  5. 5. 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 generated by the meters circuitry, resist reader interference and • without having an circumvent a lack of active transmitter to power from the transfer the reader signal due to information stored long distance. • They are different from active tags in that they only transmit data at the time a response is received
  6. 6. Frequency Appx. Read Range Data Speed Cost of Tags ApplicationLow Frequency (125kHz) <5cm Low High • Animal 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 Supply(433, 868-928 Mhz) Chain (passive) • Baggage TrackingMicrowave (2.45 & 5.8 10m -15m High High • Electronic tollGhz) collection (Autotoll) (passive) • Container Tracking 20m – 40m (active)

  10. 10. + Target: SME+ Information: Opinion on RFID and its applications+ Site: – http://qtrial.qualtrics.com/SE/?SID=SV_9N5UPRZu yuWtsk4
  11. 11. 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
  12. 12. + In medical uses and library management
  13. 13. + 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
