RFID based Smart Attendance System using Nodemcu & Firebase

In this tutorial, I have created a Smart Attendance System. In this system, Smart Attendance Admin Panel is made using Html, CSS, Bootstrap, Jquery, Javascript.
You can add users to the system in "INIT" mode. The rfid tags(or users) is read using the RC522 Rfid reader.
Admin can then monitor all the users present in the system.
The user's check-in and check-out time is also downloadable as csv file. The current user status is also monitored in realtime using Firebase Realtime database.
