The requirement is for them to be able to execute CRUD (Create-Read-Update-Delete) operations using a MongoDB database to manage the students.Īlso, they wanted to scan the QR code on the same web application and do the validation on the same database, and display the result of the validation in real time ( whether “access denied” or “access granted”). However, I have worked personally on one Internet of Things (IoT) project wherein I needed to create an IoT web application that will authenticate users by scanning their auto-generated QR code. OpenCV by default has no native support for web browsers. So why have I chosen the web browser to display the QR Scan reading? Why use a web browser for QR Code reading using OpenCV? OpenCV QR Code Validation using Web browser It is either you are shown an “ Access Granted” or “ Access Denied” message. We will be streaming the video captured by your webcam on your web browser using the Flask microweb framework and if a QR Code is detected then we would decode it and display the validation result to your web application. We will be storing a list of valid QR codes in-memory for now (database in the future) and then using the web browser to display the result of the validation in real time. I will be creating a security/attendance system powered by OpenCV where you need to scan your QR Code to gain access to a fictitious facility. OpenCV QR Code Attendance/Security System If you want to see a demo of this project then please see the below video or watch it on my YouTube channel.

In this post, I am going to show you how you can use OpenCV for QR Code detection and reading and display real-time results using your web browser.
