DOS Attendance is an online attendance application based on Android to facilitate employee attendance data collection. This application allows every employee to do attendance online either in the office or outside the office without having to do attendance manually. It has the advantage that it is a location pin based on Google Maps for accurate and precise attendance locations if attendance is outside the office. This system is also able to perform attendance in the office with a short process. This application also makes it easier for HRD or personnel staff to collect attendance data. This application will continue to be developed with the latest features later.
