Wlan-based Rfid Technology In E-commerce Applications

With the developing and maturation of Wireless LAN (WLAN) technology, its advantage is more and more familiar with people, and people begin to seek the communication and information service at any moment, so the demand of the introduction of WLAN technology is very impending. Especially appling WLAN technology to the E-Commerce, it not only enhances the efficiency but also reduces the using of human resources, it modernizes the E-Commerce and gives people more convenience. RFID (Radio Frequency Identification) technology is a automatic identification technology which grew up from the eighties of the twentieth century.It uses the radio frequency mode to intercommunicate contactless, and from that it can exchange the data and attain the identification. Based on the comparative advantage of bar code identification technology, RFID technology became to developing and expending in the field of logistics, store management and identification,etc, and it is more and more familiar and fond with people.The application of RFID technology to WLAN can exert and combine the advantages of both, and it not only realizes the contactless identification, but also links the identification data and the background data through WLAN. E-Commerce developes rapidly, especially in hotel, marketplace and supermarket,etc, the business can go to systematism through the computer management, if we can apply this technology in E-Commerce by aiming at their actuality, this technology can gain more function.The paper demonstrates widely the development actuality of WLAN> RFID and the combination of both, begins form the history, introduces the technology ot WLAN and RFID, researches the work principle of RFID system, recounts the realization mode of data transmission in RFID system in emphasis, and puts forward and researches a RFID system based on WLAN detailedly, including systemic composing, network topology configuration, priciple, function module and systemic advantage.The research aims at the actuality of GuangDong Hotel Restaurant Management...
