    • FutureIntroduction development of RFID Application Survey result conclusion and opportunities10/23/2012
    • RFIDRFID = Radio Frequency IdentificationElectronic labeling and wireless identification of objectsusing radio frequencyTag carries with its information • a serial number • Model number • Color or any other imaginable dataWhen these tags pass through a field generated by acompatible reader, they transmit this information back to thereader, thereby identifying the object
    • RFID COMPONENTSA 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 chipA reader/antenna system to interrogate the RFID inlayApplication software and a host computer system
    • RFID TAGThe RFID tag consists of an integrated circuit (IC) embeddedin a thin film medium.Information stored in the memory of the RFID chip istransmitted by the antenna circuit embedded in the RFIDinlay via radio frequencies, to an RFID reader3 types • Passive • Semi-passive • Active
    • TYPES OF RFID TAGS Active Tags Semi-passive Tags Passive Tags• Use a battery • Contain built-in • Derive their• communicate batteries to power power from the over distances of the chip’s field generated by several meters circuitry, resist the reader interference and • without having an circumvent a lack active transmitter of power from the to transfer the reader signal due information stored to long distance. • They are different from active tags in that they only transmit data at the time a response is received
    • 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 Frequency 3m -7m Moderate to High Low • Logistics and Supply Chain(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)

    • ONLINE SURVEYTarget: SMEInformation: Opinion on RFID and its applicationsSite: • 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%
    • FURTHERDEVELOPMENTIn medical uses and library management

    • CONCLUSIONPositive • 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 usNegative • Cost is relatively remain high (compare to barcode) • RFID signals may have problems with some materials • RFID standards are still being developed
