Biometric attendance system using fingerprint scanner and NodeMCU with a database & 3D printed case

Hi everyone.
As we know any attendance system must be secured whether it uses RFID cards or fingerprints or something else.
So as you've already known the RFID based attendance system uses tags, which can be exchanged between users, while the biometric attendance system uses organic matter that cannot be exchanged and that's a good thing.
Recently, I made two videos on using RFID as an attendance system, and many guys asked me to make it using the fingerprint scanner.
Therefore in this video, I'm going to show you how to make a full attendance system using fingerprint scanner and NodeMCU, Also there a website and database to store the users' data and their logs.
**************************************************
The instructions that you need:
1_ The parts:
1* NodeMCU
2* Fingerprint scanner
3* OLED display 0.96in
2_ Install the ESP boards on the Arduino IDE using the additional links:
http://arduino.esp8266.com/stable/package_esp8266com_index.json
https://dl.espressif.com/dl/package_esp32_index.json
3_ Include the Adafruit libraries:
https://github.com/adafruit/Adafruit-GFX-Library
https://github.com/adafruit/Adafruit_SSD1306
https://github.com/adafruit/Adafruit-Fingerprint-Sensor-Library
4_ Download the NodeMCU_Fingerprint code.
5_ Put your WiFi credentials( SSID, Password) with your computer IP or your Server domain in case you're using a public one.
6_ Install a local server like xampp server or wampserver:
Xampp:
https://www.apachefriends.org/download.html
Wamp server:
http://www.wampserver.com/en/#download-wrapper
7_ copy the biometric attendance folder into xampp/htdocs folder or into wamp/www folder.
8_ go to localhost/biometricattendance/install.php in order to install the database.
9_ then go to http://localhost/biometricattendance/index.php to start.

Actually, the full process is a bit complicated and I couldn't explain everything in the video.
**************************************************
Note: These codes for the old version:
I will upgrade the code from time to time so consider checking it on my GitHub repository, this code version is 1.2
Download The diagram, the NodeMCU code, the 3D module and The website files from here:
https://github.com/InfinityWorldHI/Biometric-attendance-system
In case you want to use ESP32 then use this code:
https://github.com/InfinityWorldHI/ESP32-Fingerprint-scanner
The Fingerprint scanner is connected to Tx2 & Rx2
The OLED display is connected to (22 SCL, 21 SDA)
