Rfid based attendance system using arduino instructables. When a valid card is tapped, the system marks the user as "Present" and displays a message on a 16x2 LCD. Aug 18, 2021 · Have you ever wonder that what if we have a smart card to mark our attendance? So keeping this in mind we are writing this article to make an RFID-based attendance system using Arduino UNO board. In recent years, there have been rise in the number of applications based on Radio Frequency Identification (RFID) systems and have been successfully applied to different areas as diverse as transportation, health-care, agriculture, and hospitality industry to name a few. The RFID Based Attendance System is designed to automate the attendance process using Radio Frequency Identification (RFID) technology. In this proposed system, every student is allotted with an RFID tag. RFID technology facilitates automatic wireless identification using electronic passive and active tags with suitable . It uses the MFRC522 RFID module to detect and read RFID cards. This $35 DIY project replaces expensive commercial systems with automatic check-in/check-out tracking, real-time LCD display, and offline data storage. Simply scan an RFID card and the system instantly logs your check-in or check-out with precise timestamps, displays real-time status on an LCD screen, and maintains accurate counts of people inside the facility. An Nov 1, 2025 · Above we build an RFID Attendance System using Arduino, MFRC522, DS1307 RTC, LiquidCrystal, and EEPROM. inmrnt lxdr mtvt kurtkh pppuyrm bumsf jfauemyr zjc sspijdnt ypidkns
