主动式二维码考勤系统研究

提出了一种新型主动式考勤方式,并给出了一种结合二维码的应用方式.该方法大大节省了硬件支出成本,同时加快了考勤速度.综述了现阶段其他研究成果,并研究了主动式二维码考勤和被动式二维码考勤的区别.;A new attendance mode, active-attendance-mode is put forward, and a viable method combined with OR-code-picture is given. The very advantage of this mode cannot only deduce the hardware cost but greatly raises the speed of detection. Other studies are illustrated and the differences of active-OR-code-attendance and passive-OR-code-attendance are compared
