The QR Code time clock system uses a mobile app. To use it, employees need to install the app from the App Store and complete the registration process. Once the mobile number is registered, the manager/admin needs to set up employee information in the system. With this step, employee tracking starts automatically and managers have employee location available in real-time. The user/employee can open the app to take additional notes, including scanning the QR code. When the QR code is scanned, a note with the details of the QR code is submitted and available in Google sheets.
