  • The innovation of display technology apply in television12207128Wong Pik Yan
  • Introduction of display Future technology applications Survey result conclusion development apply in television
  • 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
  • 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
  • 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
  • Types of RFID TagsActive Tags • Use a battery • communicate over distances of several meters Semi- • Contain built-in batteries to power the chip’s circuitry, resist interference and circumvent a lack of power from the reader signal due to long distance.passive Tags • They are different from active tags in that they only transmit data at the time a response is received • Derive their power from the field generated by the readerPassive tags • without having an active transmitter to transfer the information stored
  • Applications Frequency Appx. Read Data Speed Cost Application Range of Tags Low Frequency <5cm Low High • Animal Identification (125kHz) (passive) • Access Control High Frequency 10 cm – 1m Low to Mediu • Smart Cards (13.56 Mhz) Moderate m to (passive) Low • Payment (paywave) Ultra High 3m -7m Moderate to Low • Logistics and Supply Frequency (433, High Chain 868-928 Mhz) (passive) • Baggage Tracking Microwave 10m -15m High High • Electronic toll collection (2.45 & 5.8 Ghz) (Autotoll) (passive) • Container Tracking 20m – 40m (active)
  • Current Applications Application Representativ Competitive Current Typical Tag Type Segment e Applications Technologies Penetratio n Access Control Doorway entry Other keyless entry High Passive technologies Asset Tracking Locating None Low Active tractors within a freight yard Asset Tagging Tracking Bar Code Low Passive corporate computing systems Authentication Luxury goods Holograms Low Passive counterfeit prevention Baggage Positive bag Bar Code, Optical Low Passive Tracking matching Character Recognition
  • Credit Cards with RFID(Paywave function) Applications Octopus (Smart Card)
  • Autotoll (Electronic toll collection) Applications Access Control
  • Online Survey• Target: SME• Information: Opinion on RFID and its applications• Site: ▫ http://qtrial.qualtrics.com/SE/?SID=SV_9N5UP RZuyuWtsk4
  • Survey Result How many TV do you have? 1 2 3 4 2% 11% 41% 46%
  • Further Development• In medical uses and library management
  • Video
  • 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
