Attendance Checker for Students of Mapúa University

AttendanceChecker for Students of Mapúa University 

OBJECTIVES 

The design primarily aims to create a system for recording the attendance of students without the use of the pen and papermethod. Specific Objectives are as follows: a.To create a device that uses the RFID chips of the student’s ID in order to record their attendance. b.To create a device that will record the student list through an android application. c.To create a device that will allow the instructor to know whether the student belongs to the class or not. Code Shoppy d.To create a device where the professor can access the files through their smartphone or their PC. 

CONCEPTUAL FRAMEWORK 

Firstly, a new student card is flashed to the RFID Reader to capture and recognize the unique ID in the card. The captured ID is then used to register the mapped student ID into the system. Once registered, the student card can then be used by flashing it to the RFID Reader to record the student attendance. For this purpose, the log data, which include the current timestamp, is also recorded[6]. The RFID tag that has been obtained will then be sent to the Raspberry Pi to be analysed. Upon comparison of the RFID code and the data within the Raspberry Pi, the name of the student along with their credentials (i.e., student number and whether they belong in the respective section) would be obtained. The corresponding student will then be marked as present for that day by the device. The next step is to connect the Raspberry Pi to the device of the professor by the use of a personal hotspot and anandroid application. Through the use of the android application, the professor is able to update his records in hisdevice. The data that would be obtained from the Raspberry Pi to the professor’s personal device is obtainable as it would be a .csv file (comma separated value file) which is a universally usable in most file readers. 

GENERAL SYSTEM DESIGN

 The general design of the system is mainly composed of 5 parts. The first part, which is the RFID, is the Mapúa student ID. It contains a unique code that represents each and every student in the school[7]. It will serve as the attendance of the student once it is tapped on the RFID scanner. This code is sent to the Raspberry Pi using an RFID scanner. The system will detect the student ID and record their attendance[8]. The Raspberry Pi is responsible for (a) storing the unique ID from the students’ ID done through registration; (b) recording the timestamp when the ID was tapped[9]; (c) determining whether the student belongs to the specific class or not. Through wireless LAN, the instructor is able to retrieve the attendance record and update the file. The Raspberry Pi uses a USB wireless dongle that has a hotspot capability so that a smartphone can connect to it. The smartphone uses an application to interface with the device[10]. A software application is installed and executed in the smart phone to facilitate the registration and administration of attendance.

RESULTS 

Table 1 shows the tests for whether the registration of RFID tags to a class is successful. In the test, the meaning of a “Successful” expected output means the RFID tag is registered to a single unique student successfully. While an “Unsuccessful” expected output is because the same RFID tag cannot be registered on more than one student per class. TABLE 1:RFIDTAG REGISTRATION TEST
