    • RFID APPLICATION Chan Ho Tin 12203718 Friday, October 26, 2012
    • FutureIntroduction Survey development Application Conclusion of RFID Results and opportunities
    • 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
    • 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
    • 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
    • TYPES OF RFID TAGS 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
    • APPLICATIONSFrequency Appx. Read Range Data Speed Cost of Application TagsLow Frequency <5cm Low High • Animal Identification(125kHz) (passive) • Access ControlHigh Frequency (13.56 10 cm – 1m Low to Moderate Medium • Smart CardsMhz) to Low (passive) • Payment (paywave)Ultra High Frequency 3m -7m Moderate to High Low • Logistics and Supply Chain(433, 868-928 Mhz) (passive) • Baggage TrackingMicrowave (2.45 & 5.8 10m -15m High High • Electronic toll collectionGhz) (Autotoll) (passive) • Container Tracking 20m – 40m (active)

    • ONLINE SURVEY Target: SME Information: Opinion on RFID and its applications Site: • http://qtrial.qualtrics.com/SE/?SID=SV_9N5UPRZuyuWtsk4
    • 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%
    • 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
