The number of students enrolling in educational institutions is always increasing every year. As the attendance records of a student indicate the punctuality and discipline of a student, teachers use attendance in giving out final grades and so it has become necessary to device newer and better technologies for recording student attendance and maintaining records. Usually, attendance is taken using paper sheets and then the record is manually updated into a register or a system. This method is however time consuming and flawed in many ways. This paper focuses on harnessing the potential of the ever-increasing technology of into building a portable attendance system which tries to erase many of the flaws in the conventional method of taking attendance and makes the procedure more concrete and automatic. Portable devices like an enabled smart phone can be used to implement this project. In order to solve the problem that it is inconvenient to find books in the traditional library, a kind of book positioning system using RFID technology is designed to achieve fast search books in the library. The JRM2030 RFID reader module is used to locate and search books with electronic labels on the bookshelves. The system software is designed by using LABVIEW. And the book positioning system can search books by typing in the title of them, and get the distance between the tag and the reader referring to the strength of wireless signal. In this paper, the hardware and software of the system are designed in detail, and the experiment results are given. The results show that the system can quickly find the books that bookworms hid, and the books that are not timely put back on the shelves. The reader can also quickly find the books in the library. Upon testing, Web-based Laboratory Attendance System (LAS) is successfully facilitated the students’ attendance and laboratory management on evaluation of student performance for experiment.
