The professor shall login in his/her attendance control panel and choose a section to perform roll call to. Afterwards, the system would display a QR Code that students will be able to scan through the dedicated mobile app.
The QR code will be disabled in 60 seconds and all students will get a confirmation notice on their phones on whether they have been marked as "attended" or not.
Android users can download the app using this link.
iPhone users need to get invited by the department to download the app. You can get your invitation by sending an email to the CSE department Administrative Assistant.
