COLLEGE AUTOMATIC ATTENDANCE SYSTEM (CAAS)
Due to globalization and easy availability of almost all information on the internet these days, students are less motivated to come to the lecture rooms or laboratory. Most educational institutions' administrators are concerned about student irregular attendance. There is often clear co-relation between student‘s attendance and over all academic performance. Absenteeism can cause the institution to lose its reputation as well as resulting in inadequate learning on the part of the student. Higher authority in universities also demands that institutes concerned with students and education keep a large amount of data, including attendance and absence levels, performance and agreements regarding individual assistance.
Attendance of students is very important factor since it forms part of the students’ assessment and evaluation. It has therefore become imperative that proper measures should be put in place to ensure that no student signs for another. Every organization whether it be an educational institution or business organization, it has to maintain a proper record of attendance of students or employees for effective functioning of organization. It is vital for educational sectors to have solutions that simplify and increase the speed of data collection and increase the lectures efficiency.
Many students go to colleges/universities which are far away from their home town. In this case parents remain unaware of the activities of their children. They are unaware whether their children are in college or bunking the classes. In most of the colleges/universities there is no system through which Authorities can connect directly to the Parents and inform their child’s behavior in College.
Designing a better attendance management system for students so that records are maintained with ease and accuracy as well as removing the communication gap between college authorities and parents is an important key behind development of CAAS.
Manual entering of attendance in log books becomes a difficult task and it also wastes the time. Reading out the names of each student, each hour destroys the precious time. So we designed an efficient system that comprises of Biometric / RFID sensor to manage the attendance records of students.
CAAS can be a powerful tool in managing student‘s attendance throughout the working day and also enhance the classroom security. A real time intelligent system is implemented in conjunction with Biometric / RFID hardware to record students’ attendance at lectures and laboratories in a college/university environment.
CAAS is designed to collect and manage student’s attendance records from Biometric / RFID devices installed in all the class rooms. Apart from the attendance collection management, it will send an automatic SMS to parents regarding total number of classes attended by their children daily.
Traditionally - students attendance are taken manually, i.e. registration of all students attendance present in a class is made in an attendance register. Due to this, there is a loss of time for students and lecturers as well as the validation and insertion of data is done manually. There may be chance of tampering the data.
Apart from that manual attendance taking and report generation has its own limitations. It is well enough for 30-60 students but when it comes for taking attendance of students in large number, it is very difficult. For taking attendance in a lecture, conference, etc. roll calling and manual attendance system is a failure. Lot of precious time is wasted over responses of students during roll call.
Moreover, the attendance report is also not generated on time. To overcome these non-optimal situations, it is necessary that we should use a full proof automatic attendance system.
CAAS provides robust, secure and automatic attendance management in Colleges.
With the help of CAAS, student attendance management becomes easier, more efficient and accurate. Proxy attendance can be eliminated and parents can be informed automatically at a daily basis about the attendance and performance of their children.
For example: “Your child was Present in English, Physics, Biology Late in Digital Electronics and Absent in Maths classes."
RFID or Radio Frequency Identification is a technology in which wireless communication is used between RFID tags and RFID Reader. The Radio frequency used in our reader is 125 kHz which is a Low Frequency (LF). RFID reader interfacing with micro-controller is done using serial port.
RFID reader will communicate with microcontroller using serial communication. When RFID tag comes in the range of RFID Reader, then reader detects RFID card and sends out a series of alphanumeric unique codes on the serial port. So while adding the lecturer/student card number in the program memory we need to store this series of alphanumeric code into program memory and later on this unique series of codes will be compared with the incoming card number. We use normal RFID cards which are of the size of credit card. These are rectangular in shape and white in color and can be attached with the ID-card.
Biometric Identiﬁcation Systems are widely used for unique identiﬁcation of humans mainly for veriﬁcation and identiﬁcation. Biometrics is used as a form of identity access management and access control. So use of biometrics in student attendance management system is a secure approach. There are many types of biometric systems like ﬁngerprint recognition, face recognition, voice recognition, iris recognition, palm recognition etc. In case of CAAS, we are using ﬁngerprint recognition system.
Fingerprints are considered to be the best and fastest method for biometric identiﬁcation. They are secure to use, unique for every person and do not change in one’s lifetime. Besides these, implementation of ﬁngerprint recognition system is cheap, easy and absolutely accurate.
Fingerprint recognition has been widely used in both forensic and civilian applications. Compared with other biometrics features, ﬁngerprint based biometrics is the most proven technique and used in most of the organizations. Not only it is faster than other techniques but also the energy consumption by such systems is too less.
