Provides an efficient and convenient solution for businesses and agencies to manage employee working time. We realize that the traditional timekeeping by hand or through fingerprint time attendance machines, swiping cards is a time consuming process and can cause errors in working time calculation. Therefore, we thought of developing a timekeeping software on mobile phones to help businesses and agencies manage their employees' working time more easily and accurately. The software will allow employees to time attendance in and out of the company using their mobile devices and help managers track employee working time quickly and accurately.
