ABSTRACT:

In recent years, it has becotne increasingly popublar to use tire fingerprint biometrics to manage personnel in businesses and organizations. This paper presents the fingerprint biometrics-based student attendance tracking system. This system was designed by using the Arduino and HC05 Bluetoodi module, and it was tested in a lecture hall of Thai Binh University.

Keywords: Biometric fingerprints, pupils, students.
