We came out with the idea OPASS As our main goal is to provide a smarter solution for the attendance process, we made sure that OPass provide the best experience to its users, so any user can register his attendance from hist cell phone by scanning the QR code given to him with just a press of a button, also we added support for offline scanning so the user isn't forced to have internet access every time he use the app and the data is synced automatically whenever an internet connection is found.
