Important Note

Always review scanned QR code results before opening links or sharing information. Unknown QR codes may contain unsafe, misleading, or unwanted links. Camera scanning works only after browser permission is allowed and may require HTTPS on production websites. Poor lighting, blurry images, damaged QR codes, or low contrast may prevent scanning.
