【摘要】 笔者提出一种基于身份证、一卡通识别的高校学生成绩单自助打印系统的构建方案。系统组成包括前端打印设备和后台控制程序,自助打印系统与高校主数据中心实现对接,可直接读取学生基本信息并进行身份匹配,成绩数据基于XML进行报表传输,需求方可通过扫描成绩单上的二维码验证成绩单的真伪。方案的可行性已在实际应用中得到验证。更多还原

【Abstract】 A scheme for the construction of self-help-printing system is presented in this paper. The system is designed for college student transcripts-printing based on ID cards and all-purpose-card recognition. The system consists of a front-end device and a terminal-control program. Self-service printing system is connected with the main data center. Students’ basic information can be directly read and matched. The performance data is based on XML for report transmission. The demand can be scanned on the report card. The QR code verifies the authenticity of the transcript. The feasibility of the program has been verified in practical applications.更多还原
