hey so I am in college and we have a attendance system through QR code like we have to scan It and then will get our attendance marked.. this process is done through my camp app and now what I want to do is not attend the class and I am thinking of making a bypass like only a single student will go to class and scan the QR code and then automatically 4-5 students which he will choose will also marked present.. the catch is the qr changes every 5 second so now tell me how can I do that
