Portable IoT based fingerprint biometric attendance system using NodeMCU 

In this video, I will tell you how to build a Portable IoT based Fingerprint Biometric Attendance System using NodeMCU ESP8266 12E, 0.96” OLED Display & SFG R303a Fingerprint Sensor. The ESP8266 Wi-Fi Module will collect the fingerprint data from the multiple users and sends it over the internet to a website. The Enrolment of fingerprints is done on the server using any fingerprint sensor like R303, R305 or R307 that is available on the market and verification of the fingerprint will be done on the webserver while fingerprint templates are transmitted over the WiFi.
The website used in this project is developed using PHP, it has a database and records of attendance. By logging into the website, you can collect all the attendance records of each user including personal details as well as incoming & outgoing timing. The data can also be downloaded and exported to an excel sheet.
