Here is the version 3 of RFID Attendance System using NodeMCU ESP8266 and Google. Just scan the RFID tag and the attendance data will be recorded on the Google Sheets as well as a success message will be displayed on the LCD connected to the NodeMCU. You can use this project to automate the attendance system for offices, schools and universities. I have added some new features in this project.
1. For displaying real time feedback, I have added the LCD with an I2C module.
2. I have created a very simple and easy method, to store student data on the RFID tag.
3. I have removed all the connection failed errors, By making the code more optimized.
