Resume

     I have an internship this summer in the company's work on the preparation of two-dimensional codes.Through the two-dimensional code, to improve my understanding of the two-dimensional code,understand what is the code and how to use two-dimensional two-dimensional code to live, work convenience.This report, I will share with you my acquired knowledge and discussion.  

     The bar code technology gets up from the 20th century 70's has widely applied to the commercial circulation, stores in a storehouse, domain and so on medical health, books information, postal service, railroad, transportation, production automation management. The bar code technology application enormously enhanced the data acquisition and the information processing speed, improved people's work and the living conditions, enhanced the working efficiency, and has made the important contribution for the management scientific style and the modernization.

     The two-dimensional bar code technology is to meet the practical application need under the aquirement of production when the unidimensional bar code can not do that. Along with the modern high-tech development, is urgent needs to use the bar code in the limited geometry space to express more information, satisfy the ever changing information expression the need. From this, the two-dimensional bar code arises at the historic moment.
