Design And Implementation Of Commodity Traceability System Based On NFC

In recent years, the quality and safety problems of commodity catches more and more people's attention, so it is particularly urgent to build a standardized, intelligent commodity traceability system to meet with the social demands, and by what means to trace commodity information is the key of traceability system construction.In the implementation of commodity traceability system in this paper, we introduce the NFC tag technology, namely Near Field Communication technology, which is closely combined with the links of commodity circulation, and makes commodity positioning oneto-one precisely. In the system, we nicely present the safe queries of traceability commodity information, and then effectively strengthen the supervision of commodity, so ensure the interests of manufacturers, and also increase the confidence of consumers and enhance the market competitiveness of commodity. At present, more and more users begin to pay attention to the traceability system, the quantity of users access will also continue to increase, through a large number of experimental tests and analyses in this system, we continuously improve the capability of the concurrent server, and increase the quantity of concurrent users access, so as to greatly enhance the performance of the entire system.According to the characteristics of this system and the actual commodity circulation situation both at home and abroad, we design and implement a traceability system based on NFC. First of all, we analysis and research the progresses and related technologies in domestic and international platforms on commodity traceability system. Aiming at some drawbacks and inadequacies on current traceability, such as two-dimensional bar code traceability which is easy to tamper with information, or the traceability information is not complete, so we propose to establish a stable running traceability system which has complete commodity information and enjoys strong function expansion and strict supervision. Secondly, through the analysis of the current tracing means, we put forward the commodity identification schemes on NFC tag technology. Using the global unique identification number in each NFC tag as a single commodity tag number, and writing a commodity label formulated by manufacturers into the NFC tag, eventually the two numbers cascade binding to specify the uniqueness of the commodity and verify each other, and can effectively carry out anti counterfeit. Thirdly, we design and implement a commodity traceability system based on NFC. The system includes user login module, query management module, add management module, modify management module, delete management module and system management module, each module is correspond to its own permission, so as to ensure the stringency of the system. Finally, the system contains function testing and performance testing, which can ensure the availability and reliability of it. There is a theoretical significance and practical application value of the design, implementation and research on commodity traceability system in this paper.
