Application of Two-dimensional Code to Service Expansion of Mobile Library

介绍清华大学图书馆在OPAC、迎新导引、读者手册获取和密集书架控制等场景中广泛应用二维条码技术的具体实践，在此基础上指出应用二维码技术时在呈现方式、应用场景和安全性等方面需要注意的问题，以期为各图书馆提供借鉴，使二维条码在移动图书馆服务拓展中发挥更大的作用。

With the in-depth construction of mobile library, two-dimensional code has been widely used in Tsinghua University Library under the scenarios, such as OPAC, freshmen guide, patron handbook retrieving and intensive bookshelves control. It has expanded and extended library services in time, space and mode. These services are welcomed and well received by patrons. Based on the practices with two-dimensional code, this paper points out the problems in the application of presentation, application scenarios and security. With the increasing popularity of smart phones in the campus, two-dimensional code will play a greater role in the expansion of mobile library services.
