ABSTRACT
The study was entitled Automated Classroom Magnetic Door Lock with
Attendance Monitoring System Using Radio Frequency Identification was developed to
automate mainly the attendance montoring system of teachers and students of the Notre
Dame of Tacurong College and to provide classroom security and maintenance access.
The main onjective of the study was to developed an Arduino and Visual Studio
2015-based attendance monitoring system which accepts Radio Frequency Identification
Tag data and set of numeric codes for room security password. The Radio Frequency
Identification or RFID enabled the system to capture and record the Lates and Absences
of both teachers and students while the set of numeric codes gave the school personel
access to classrooms to perform security and maintennace without using the RFID tag
and RFID reader. The proposed system provided the following benefits such as fast and
accurate systematic data recording, eliminated attendance roll calls, data security and
maintenace, saved money, time and effort and paper works, eliminated large amount of
papers used, convenience, organised data for reports and printing, as well as it minimized
electric consumption on every classrooms during class breaks. The technologies used in
the proposed system were Microsoft Visual Studio 2015, MsSql 2015 Local Database,
Arduino Uno R3 and Gizduino v.5.0 microporcessors, 16x2 Liquid Crystal Display or
LCD, 600 and 300 - LED Fail Safe Electro-Magnetic Locks, RFID Tag or Card, RFID
Readers and a Desktop Computer. The methodology of the proposed study included the
operational diagram of the proposed system, context and physical data flow diagram,
entity relationship diagram, developmental approach, schedule and timeline, and the
budgetary outlay.

After the research project was developed, the result showed that the Automated
Classroom Magnetic Door Lock with Attendance Monitoring System Using Radio
Frequency Identification satisfied the objectives of the study. When it was tested, it
showed that through the attendance monitoring, the accuracy, reliability, convenience and
security satisfied the needs of the teachers and studnents. It was highly recommended that
the system should have a centralized monitoring system control capable to network all
Automated Classroom Magnetic Door Lock with Attendance Monitoring System. should
not be limited to Microsoft Operating System (O.S.) and Visual Studio.net platforms but
should also in other platforms (i.e. Linux, Mac O.S., iOS, Java programming software).
should also provide access to students in viewing their attendance records in aweb
browser or in a mobile application using the Internet. should use two database platforms
to back up all files. should have a power backup generator or device such as
Uninterruptible Power Supply or (UPS) in case of power failure.
