Answers to common questions about MaScanner for iPhone.
Common questions
How do I enable the camera?
Allow camera access when MaScanner asks. If you previously denied access, open iPhone Settings, find MaScanner, and enable Camera. Then return to the scanner.
Why won’t a code scan?
Keep the whole code in view, hold your phone steady, and avoid glare. Try adjusting the distance or using the flashlight. For saved photos on iPhone, MaScanner supports QR codes; use the live camera for other barcodes.
How does batch scanning work?
Choose Batch in the scanner or Start Batch Scan from the home screen. Saved results appear in History. Duplicate prevention is enabled by default and can be changed in Settings.
How do I delete my scan history?
Open History, tap Clear, and confirm Clear All. This also removes favorites. Deleted history cannot be recovered within MaScanner.
Does MaScanner sync between devices?
No. Scan history and settings are stored locally. MaScanner does not provide an account, cloud sync, or a remote history backup.
How do I control sound and links?
Open Settings to change scan sound, haptic feedback, duplicate prevention, and external-link confirmation. Scan sounds respect silent mode and your device volume.
