The Information Management System Based On QR Code

Two dimensional code as a kind of identification, is also a branch of bar code. The barcode displays the information in a graphical way. According to the information carrying capacity and the performance of information in different places, it can be divided into one dimensional bar code and two-dimensional bar code. Two dimensional code carrying more informations,recording more potable text,image data and other data than one dimensional code, so that it can be applied to a wider area.The two-dimensional code deal with the pictures, text, characters and other information in the form of graphics performance, Only two-dimensional code itself doesn’t make any sense, it need scanning equipment support which can fully display its contents. With the popularity of smart mobile phone, the cost of use the two-dimensional code in intelligent machines are more cheaper and more ubiquitous, the application of the two-dimensional code from a specific field gradually used in our ordinary life. Many of the intelligent mobile phone’s APP software can have a function of scan two-dimensional code, such as We Chat,Net Ease Chat, mobile phone QQ, check price software, users can easily open the app and scan the two-dimensional code to get the needed information. So how to let the two-dimensional code play a more extensive application, how to let it’s low cost advantage comnline with the traditional business, so that our ordinary people can more easily and conveniently obtained two-dimensional code, and based on the realization of information management system, showing the value of two-dimensional code.That is the core of this Paper to solve this problem.This Paper adopt a wedding invitation card as a application scenarios which is a kind of our real daily life to research, implements a function that paste a specific two-dimensional code before sent invitations, and use the management system to make the two-dimensional code contains more and more multimedia information. After the invitee use his phone’s APP scan the special two-dimensional code, he can get the more media information which stored on the cloud server, at this moment,the system process to sending a notification to the invitation. This system’s technology in cluding : the whole stack development on the front of user interface, the server using Node.js, the database using a non relational database Mongo DB; interface also explore the APP ’s Hybrid development model. This application model is developed to expand the practical application scenarios of more two-dimensional code.
