QR Code Scanning Best Practices
Optimal Camera Distance & Focus
Position the QR code within the highlighted viewfinder. Hold the camera steady approximately 6 to 12 inches away.
Lighting & Glare Reduction
Avoid harsh reflections and shadows across the QR pattern. Ensure even illumination across all four alignment corners.
Clipboard Paste (Ctrl + V)
You can copy any QR code screenshot from another app and simply press Ctrl+V anywhere on the page to scan it instantly.
100% Client-Side Privacy
Your camera stream and uploaded photos remain strictly in your browser memory. Nothing is ever uploaded or recorded.
