The Diobox mobile apps for iOS and Android include a built-in QR scanner that makes guest check-in fast and reliable. The scanner is designed to streamline event logistics, helping your guests enter the venue quickly while giving staff the tools they need for smooth operations.
This articles includes the following topics:
Launch the Scanner
The QR Scanner is part of the Diobox app. To open it, go to the Tools tab and select QR Scanner.
Scan Activity
The scanner interface has a split-screen layout. On one side, you see the live scanner, and on the other, you see a list of recent scans. This allows staff to track check-ins without leaving scanning mode.
Each scan provides detailed guest information such as the guest’s name and photo, confirmation status, plus-ones or group count, seating assignment, and assigned guest lists.
The system also displays error messages when needed, including duplicate scans, invalid QR codes, or guests blocked by restrictions.
All scan activity is processed locally, which means scans from other devices will not appear on your screen. This ensures each device shows only its own check-ins.
Camera Controls
Switching Cameras
You can switch between the front (selfie) and rear camera by tapping the camera icon.
Flashlight
If your device has a flashlight, you can toggle it using the flash icon in the bottom-right corner, which is useful in low-light conditions.
Scanning Modes
Two modes are available:
Continuous: QR codes are scanned automatically, and guests are checked in immediately. If there is an issue, the app will prompt you with the necessary action.
Retrieve Only: Instead of checking in a guest, the app opens the guest’s profile when their QR code is scanned. This requires the door staff to review every guest and manually check then in.
Scanning modes are set per device, so you can assign different roles to different devices depending on your workflow.
Working Offline
iOS App
Because Diobox uses core technologies of iOS, the QR scanning process can work entirely offline. So if your internet connection drops off, you will be able to continue guest check-ins without any issues.
Android App
The Android app requires that you are connected online.
Advanced QR Scanner Settings
The QR scanner also includes advanced features for security and access control. For details, see:
