ABSTRACT Over the years the manual attendance system has been carried across most of educational institutions.To overcome the problem of manual attendance, now we are using a web based attendance management system, which can be implemented on any computer. This system is being developed to maintain easy access of information from the database. The application makes use of PHPMySQL HTML and CSS.It tracks all the details of a student attendance from day one to end of the course. The conventional method of takingattendance by calling names or signing is very time consuming, insecure and hence inefficient.
