Troubleshooting & FAQs

How do I scan a QR code?

• Open QR BAR.
• Tap the Scan button on the home screen.
• Point your camera at the QR code — it will automatically scan and decode the content.

Can I create my own QR codes?

Yes! Go to the Generate tab, choose the content type (e.g., URL, contact, text), fill in the details, and tap Create.

Why isn’t the camera scanning the code?

• Ensure camera permissions are enabled in Settings > Privacy > Camera.
• Make sure there's enough light and the code is clearly visible.

Where can I find my scanned or created codes?

All scans and created QR codes are saved in your History tab for easy access and reuse.
