How to punch in at work in an electronics factory?

Electronic factories usually use work permits to punch in. Electronic factories generally issue work permits to employees, which will contain employees' personal information and punching information. Employees need to use their work cards to punch in, usually at the designated place in the work area at the factory gate. After punching in successfully, the working hours and attendance of employees will be recorded in the electronic system. This method can effectively manage the attendance of employees and ensure the accuracy of working hours.
