All of you sound so damn sure when speaking about socialism. Like the first nation to pierce the firmament of human fabric wasn't a socialist one. And that the union wasn't making great strides in technology.

To log out you'd need authenticators existing in applications with the management, along with a log-out request that must be accepted first. As for taking attendance itself, at the end of each lecture, a professor would share an OTP, or a qr that changes every 5 seconds and is also valid for that period. Even before, one can scan the QR code, there would be a biometric and a geolocation check. Once all of this is complete, the attendance metadata would be sent to a server hosted in-house, and presence will be acknowledged. The problem is in someways, this system is still not foolproof. And this is the place where I need help.

Here's my approach so far:

    Biometric login: Ensures only the phone owner can log in.
    Geo-fencing: Verifies the user is within the classroom perimeter.
    OTP/QR Code: Adds a layer of real-time verification.
I'd like advice on how to improve this, because there are still some flaws in such a system. I want to avoid buying any additional hardware, and just depend on smartphones, and make it safe and anti-cheat in nature. Please chip in your expertise and experience. Thanks!
