This Android based - One Tap Attendance System is the smartest way to take attendance. Just one tap on your mobile and no more roll calls and time waste. An attendee's day-to-day attendance details are maintained by this system. It is generating the attendance of the student on basis of their presence. All that is required to be done is to open the application and get the attendance registered. The databases are backed on the daily basis of their attendance. A separate username and password will be provided to the staffs or the responsible official to make it visible to the attendee's discovery status. The staffs handling will be responsible to make the attendance for all attendees. Only if the attendee is present in that time, the attendance will be calculated. © 2020 IEEE.
