Things you should know before using the application with QR technique
The application will automatically open your smart phone’s camera as soon as you swipe “check-in” on the application in order to capture the photo of the QR code and analyze it
The application will detect the location of the mobile when swiping “check-in” and that’s to ensure that the user has truly captured the QR code from inside the company. We don’t find this applicable when using the application with the NFC technique since it is impossible to find 2 tags having the same code; it is very possible to have same QR codes however. So, to avoid manipulating the system, the application will confirm the presence of the employee in the company as well as the QR code.
