二维码技术在移动地铁购票系统中的应用研究

Research on the Application of Two-Dimensional Code Technology in Subway Ticketing System

二维码具有存储量大,保密性高,抗损性强,成本低廉,制作要求低等特性。随着二维码技术的不断发展与完善,二维码正在我们的生活中扮演重要的角色,并且二维码已应用于诸多领域,但是二维码技术在地铁方面应用匮乏。该文章总结了各类二维码的优劣势并主要研究了二维码的关键技术,加密与解密技术,并结合当前主流技术设计了一个移动地铁购票应用的案例。

Two-dimensional code has many characteristics, such as a large storage capacity, high security, strong anti loss, low cost, low production requirements. With the continuous development and improvement of two-dimensional code technology, it is playing an important role in our life, and two-dimensional code has been widely used in many fields. But the two-dimensional code technology is rarely used in the subway, there is no real subway class app to provide services to passengers. This article summarizes the advantages and disadvantages of various types of two-dimensional code and mainly studies the key technology of the two-dimensional code,encryption and decryption technology and combines with the current mainstream technology to design a mobile Metro ticketing application.
