RFID Attendance System Using ESP32 with Web Integration

Abstract

Abstract — This research is motivated by the need for a more efficient, accurate, and automated internship attendance system at the Bank Indonesia Representative Office in North Sulawesi Province. The main objective is to design and develop an internship attendance system based on Radio Frequency Identification that is integrated with a web platform, in order to accelerate attendance validation and reduce errors arising from manual recording. The applied methodology includes requirements analysis, the design of an Internet of Things‑oriented system architecture, implementation of both hardware and software components, and functional testing of card reading and attendance data management processes. The proposed system introduces an innovation in the form of contactless, automated attendance with real‑time monitoring of interns’ presence through a web interface. Experimental results indicate that the system achieves a card reading success rate of approximately 95% with a low error level, thereby improving the overall efficiency of internship administration. The study concludes that the developed system effectively supports the digitalization of attendance administration and can serve as a reference for the design of similar systems in other organizational contexts.

Tujuan utama penelitian adalah merancang dan membangun sistem presensi magang berbasis Radio Frequency Identification yang terhubung dengan platform web guna mempercepat proses validasi kehadiran sekaligus menekan kesalahan pencatatan secara manual. Metode yang digunakan mencakup analisis kebutuhan, perancangan arsitektur sistem berorientasi Internet of Things, implementasi perangkat keras dan perangkat lunak, serta pengujian fungsional terhadap proses pembacaan kartu dan pengolahan data presensi. Sistem yang dikembangkan menghadirkan inovasi berupa mekanisme presensi otomatis tanpa kontak fisik dengan pemantauan kehadiran secara real-time melalui antarmuka web. Hasil pengujian menunjukkan tingkat keberhasilan pembacaan kartu mencapai sekitar 95% dengan tingkat kesalahan rendah, sehingga mampu meningkatkan efisiensi prosedur administrasi magang. Berdasarkan temuan tersebut, penelitian menyimpulkan bahwa sistem ini mendukung upaya digitalisasi administrasi presensi dan berpotensi dijadikan rujukan dalam pengembangan sistem presensi serupa di lingkungan lain.
