Abstract — RFID Attendance System IoT
the user. If an unauthorized person or tag is scanned, the system will request permission to scan from an admin user, enhancing the security and reliability of the system. Admin users can view all users and their attendance, as well as view attendance in real-time, as dashboards, graphs, and analytic reports via the web-based portal of the attendance system. This system is designed to be scalable and adaptable for use in a variety of settings, including educational institutions and office spaces. Not only does it simplify the management of attendance, but it can also provide valuable data and details regarding patterns of attendance, which help verify and justify the use of resources and determine performance. The solution offers secure access, ease of use, and rapid data access and control, which improves the overall management of the institution.
Operational Methodology & Framework
In this project, we will create an IoT-based RFID attendance system using the IndusBoard Coin with the ESP32-S2 chip. The system will read RFID card Unique Identifiers (UIDs) using an MFRC522 module, record attendance with precise timestamps, and display it in real-time on a web page hosted by the ESP32-S2. Each RFID card will be associated with a specific user, and the web page will show the punch-in and punch-out times along with the current status (e.g., “In” or “Out”). The system leverages WiFi connectivity to sync time via the Network Time Protocol (NTP) for accurate date, time, and day, and uses dynamic arrays to manage user data. Unknown UIDs trigger a separate entry webpage for new user registration, appending details to the user database. The coding integrates libraries such as WiFi, NTPClient, SPI, MFRC522, and WebServer, with a structured workflow for initialization, RFID scanning, attendance logging, and web serving. Testing involves verifying hardware connections, WiFi and NTP synchronization, RFID functionality, and webpage responsiveness, ensuring a robust solution for educational or professional attendance tracking.
Experimental Findings & Validation
The IndusBoard COIN with the ESP32-S2 chip serves as the central microcontroller for this IoT-based RFID attendance system. The hardware connections involve interfacing the ESP32-S2 with an MFRC522 RFID module and ensuring proper power and communication lines. Here’s a step-by-step breakdown: For coding the MFRC522 library and NTP for network time library ae used can be installed using library manager . other tahn these libraries few more are used Figure 1: Conceptual Model & Experimental Workflow for Rfid Attendance System Iot 2.
