Android Devices Student Attendance Management System

Android Devices Student Attendance Management System

Abstract—An attendance management system is developedsuch that the students present in the class can register theirattendance by scanning their student ID cards over not only theteacher’s terminal device but also their own personal Androiddevices. https://codeshoppy.com/shop/product/student-attendance/  This system solves the problem with the conventionalsystem that it took a long time for all the students to scantheir cards by a single terminal device. In order to spoilcheating students who try to resister their attendance illegallyfrom outside the classroom, we employ a BLE (Bluetooth LowEnergy) beacon device to transmit a magic number necessaryfor proper registration within the classroom.Keywords-android; NFC; BLE Beacon; attendance manage-ment system; 

DEVELOPED SYSTEM 

A. IdeaIn the former existing systems the students had to scantheir cards individually one after another, which takes muchtime until all the students are registered. The focus of theproposed system is to decrease the time by scanning the IDcards over multiple Android devices in parallel. We may usethe Android smartphones owned by the students.In order to spoil cheating students who try to resister theirattendance illegally from outside the classroom, we employa BLE beacon device to transmit a magic number. Only theAndroid devices of the students present inside the classroomreceive the signals of the beacon device that carries themagic number. This signal covers the entire classroom about30meters wide and long and is blocked by the walls. TheAndroid device is requested to send the scanned ID andname together with the received magic number for properregistration.

B. System overviewFigure 1 shows an overview of the developed system.The proposed system has two parts, which are an Androidapplication for the students and a web-based managementsystem for the teachers. The students are supposed to haveinstalled the application in their android devices. The teachershould create a set of class ID, name, and a magic numberbeing the identifier of the BLE beacon on the web system.1) The teacher prepares a set of ID and name of the classon the web-based management system before startingthe class.2) Then, the teacher turns on the BLE beacon to transmita magic number to the Android devices within theclassroom.3) Next, the students run the application and scan theircards over the NFC reader. The near-by classmates canalso use those devices.4) The Android devices within the classroom receive themagic number transmitted from the BLE beacon.5) Finally, the Android devices send the scanned ID andname together with the received magic number to theserver. 

C. Android application for registration of attendanceThis system works on the Android devices which is themajor operating system for smartphones. The students scantheir ID cards over the NFC reader after they run theapplication. The ID and name read out of the student’s IDcard are displayed on the screen as shown in Fig. 2.When the register button is clicked, the application startslooking for a BLE beacon device. On detection of a beacondevice, the application sends the identifier of the detectedBLE beacon device to the server. Then the corresponding setof class ID and name is looked up by the beacon identifierand is sent back from the server. As shown in Fig. 3, a listof the classes taking place in this and near classrooms maybe displayed. The students selects the class to register outof the list.
