attendence system using QR code

      

ABSTARCT :

Smartphones are becoming more preferred companions to users than desktops or notebooks. Knowing that smartphones are most popular with users at the age around 26, using smartphones to speed up the process of taking attendance by university instructors would save lecturing time and hence enhance the educational process. This paper proposes a system that is based on a QR code, which is being displayed for students during or at the beginning of each lecture. The students will need to scan the code in order to confirm their attendance. The paper explains the high level implementation details of the proposed system. It also discusses how the system verifies student identity to eliminate false registrations.

EXISTING SYSTEM :

These systems streamline the process of tracking attendance by leveraging the convenience and efficiency of QR codes. In an educational setting, for instance, QR code-based attendance systems allow teachers to generate unique QR codes for each class session or student. Students simply scan the code using their smartphones or tablets to register their attendance. The system records the time and date of each scan, and attendance data is automatically updated in a central database, making it easy for teachers to monitor and manage attendance without manually taking roll calls. Some systems also incorporate real-time reporting, enabling students to track their attendance history and administrators to generate detailed reports for analysis.

DISADVANTAGE :

Requires smartphones or QR scanning devices: Students or employees must have access to a smartphone or a device capable of scanning QR codes. QR code spoofing or duplication: QR codes can be easily duplicated or shared, allowing someone else to mark attendance on behalf of another person. Scanner malfunction: If the device used for scanning QR codes experiences technical issues, it may prevent accurate attendance recording. Crowd scanning issues: In large classes or meetings, scanning each individual's QR code can be slow and inefficient, especially if there are delays in getting the code recognized. Buddy punching: Similar to biometric attendance systems, QR-based systems could face issues of people scanning in for others (i.e., someone else scanning a code to mark attendance for someone who isn't present).

PROPOSED SYSTEM :

The system lies between online learning and traditional learning as a facilitation for the attendance record-keeping process, in a way that enriches the lecture time so that it can better be utilized in giving useful materials rather than wasting the time taking attendance. The system requires a simple login process by the class instructor through its Server Module to generate an encrypted QR code with specific information. This can be done at any time before the class. During the class, or at its beginning, the instructor displays an encrypted QR code to the students. The students can then scan the displayed QR code using the system Mobile Module, provided to them through the smartphone market by the university. Along with the student’s facial image captured by the mobile application at the time of the scan, the Mobile Module will then communicate the information collected to the Server Module to confirm attendance. The whole process should take less than a minute for any student as well as for the whole class to complete their attendance confirmation.

ADVANTAGE :

Quick attendance recording: QR codes allow students or employees to check in or mark attendance quickly by simply scanning the code, reducing the time spent on manual roll calls or signing in. Automation of attendance: The system automatically records attendance without the need for a human to monitor the process, saving administrative time and effort. Low-cost implementation: QR codes can be generated and distributed easily with little cost, especially when compared to more complex biometric or RFID-based systems. Ease of use: Users only need a smartphone or a QR code scanning device to mark their attendance, making the system very user-friendly. Reduces human errors: Unlike manual attendance systems, QR codes reduce the possibility of mistakes caused by incorrect data entry.
