This project demonstrates an RFID card reader system using an Arduino microcontroller, an OLED display (SSD1306), an RFID module (MFRC522), and a servo motor. When an RFID card is scanned, the system ...

Traditional check-in systems often rely on manual processes that are prone to errors and time-consuming. To overcome these challenges, we developed an RFID Based Check-In System using Arduino, RFID ...
