It hasn't been coordinated to notify the shutdown by SMS. Do I need to punch in?

Hello, let me answer this question; I think it is necessary, and you don't know what the specific measures are. What if the company doesn't pay wages under this micro-excuse? Of course, you can complain to the Labor Dispute Arbitration Institute of your Human Resources and Social Security Bureau. Of course, in this case, you missed the clock. To prove that you are not absent from work, you must have evidence or witnesses. For example, the information you handled at work that day, the testimony of colleagues and so on. You can also apply for the video surveillance of the company on that day. Only if you have evidence or witnesses to prove that you were at work that day, the company can't treat it as absenteeism. Another thing to remind you is, have you decided not to work in this company? Don't complain if you still work in this company. If you miss a day, you can deduct some money at most. If you want to continue working in the company and complain, the company has many ways to deal with you. For example, you missed punching in. Although you have proof that you are not absent from work, the company can't punish you for being absent from work. But the company can punish you in the name of "you don't punch in, which violates the company management system" The above answers are for reference only.
