背景技术Background technique

在日常的工作中，公司或单位会组织一些会议或者活动，并要求人员参加。为了保证参加会议或活动的人员准时参加，参加活动或会议的人员被要求签到，以对参加活动或会议的人员进行管理。而传统的签到方式都是人员在纸质的签到表上进行签到。In daily work, companies or units organize some meetings or activities and require personnel to attend. In order to ensure that the people participating in the meeting or activity attend on time, the personnel participating in the activity or meeting are required to sign in, so as to manage the personnel participating in the activity or meeting. The traditional sign-in method is that personnel sign in on a paper sign-in form.

然而，纸质签到的方式很容易出现签到作弊的情况，例如，参加会议或活动的人员代替未参加的人员签到，使得纸质签到表中的签到信息不能真实反映参加会议或活动的人员情况，签到信息不准确。However, the paper check-in method is prone to check-in cheating. For example, people who participated in the meeting or activities signed in instead of those who did not participate, so that the check-in information in the paper check-in form cannot truly reflect the situation of the people who participated in the meeting or activities. Sign-in information is incorrect.
