The Design And Implementation Of A QR Code-based Mobile Phone Sign In System

The application of one-dimension barcode has been widely used in many fields through dozens of years, it has brought the automatic identification technology a revolutionary change. Compared with one-dimension barcode, two-dimension bar code has a unique advantage, with its high reliability, strong error correction performance, more large data capacity and higher safety and so on, all of these make two-dimension barcode a widely promotion and use in production and life.As a type of two-dimension bar code, QR (Quick Response) code is a matrix type of two-dimension barcode, besides the advantages of two-dimension code, but also it has other advantages, such as the high speed and all-round recognition, extensive coding characters, and more effective Chinese characters to use, so it is widely used in China.Compared with the traditional way in meeting the defects and insufficiency, the QR Code-based mobile phone sign in system not only bring higher user experience to the forum guests, but provide the large and medium-sized meeting guests a way of work and life with fast, efficient and low carbon environmental. At the same time, it bring the meeting planners away from the tedious meeting preparation work, such as designing conference invitation letter, printing meeting documents and so on, then they will have more time to focus on the content of the meeting itself, in order to achieve an efficient meeting.According to the particularity of the mobile phone sign in system, we suggest a management model of the two-dimension code which based on the encoding and decoding technology of the two-dimension QR code, a thought of the distributed database design, and the system access control and mission control, these can provide the whole system an effective operation.
