Project Description:

The RFID Based Attendance System Using Arduino and RC522 RFID module is a project that aims to automate the attendance process using radio-frequency identification (RFID) technology. The project uses an Arduino microcontroller board and an RC522 RFID module to read the RFID tags attached to each individual, and a 16x2 LCD display and a buzzer to provide feedback.

Working Method:

The RFID tags are attached to each individual's ID card or wristband. The RC522 RFID module reads the tag information and sends it to the Arduino board. The Arduino board compares the tag information with the stored data to identify the individual and marks his/her attendance. The attendance data is then displayed on the 16x2 LCD display.

If the individual's tag information is not recognized or there is an error, the buzzer is triggered to alert the individual and the attendance is not marked. This helps to prevent errors and ensures accurate attendance records.

To set up the project, you will need to connect the RC522 RFID module to the Arduino board and program it to read the tag information. You will also need to program the Arduino board to compare the tag information and mark the attendance. Finally, you will need to connect the 16x2 LCD display and the buzzer to the Arduino board and program them to display the attendance data and provide feedback.

Overall, this project provides an efficient and reliable way to automate the attendance process using RFID technology. It can be used in schools, colleges, offices, and other institutions to streamline attendance records and reduce manual errors.
