    • Introduction of RFID Applications Survey Results Future Development and Opportunities Conclusion
    •  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
    •  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
    •  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
    • Active Tags •Use a battery •communicate over distances of several meters Semi-passive Tags •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. •They are different from active tags in that they only transmit data at the time a response is received Passive Tags •Derive their power from the field generated by the reader •without having an active transmitter to transfer the information stored
    • Credit Cards with RFID (Paywave function) Octopus (Smart Card)
    • Autotoll (Electronic toll collection) Access Control
    •  Target: SME  Information: Opinion on RFID and its applications  Site:  http://qtrial.qualtrics.com/SE/?SID=SV_9N5UPRZ uyuWtsk4
    • Enhanced customer satisfaction Improved efficiency Increased inventory turnover rate Reduced manpower Reduced total cost 0 2 0 2 1 0 2 1 3 0 1 1 0 1 0 3 4 4 4 4 Benefits of using RFID in differentindustries Manufacturing Retailing Transportation Warehousing
    •  In medical uses and library management
    •  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
