Smart attendance system using RFID and Wi-Fi module

The combination of Electrical Engineering (EE) and Information Technology (IT) has played a significant role in developing several aspects in academic and professional sectors such as student or employee monitoring. It is a critical subject to track and to manage employee attendance in work places urging employees to attend on time to increase efficiency of work, so is at schools or colleges for students. Hence, an attendance system can be useful to reduce administrative complexity and cost. The conventional pen-paper based attendance system is not absolutely flawless. In this paper we have designed an attendance system using RFID and Wi-Fi Module. Radio Frequency Identification (RFID) is an extensive application to yield maximum advantage of this technology with minimal effort for management and attendance monitoring. But it is hard to keep track of every individual only through monitoring. At such times we need an online solution. We have used Node MCU for this purpose. It is a complete and self-contained Wi-Fi network solution that can carry software applications as a stand-alone device or connected with a microcontroller.
