Is it appropriate for migrant workers to go to the construction site to take photos and punch in?

At this stage, migrant workers require workers to take photos and punch in with their mobile phones. Nowadays, many workers take photos on their mobile phones with a fish bubble watermark camera, which will display the working time, place and project, improve the efficiency of punching in, and also allow workers to send photos to you. As attendance records, they are clear when they check out at the end of the month.
