Wyjaśnienie techniczne
The scanner uses the browser BarcodeDetector API when available and falls back to a bundled QR decoding library for uploaded images. Camera frames are processed in the page and never transmitted.
QR decoding is not a guarantee of safety. A QR code can hide a shortened or deceptive URL. Always inspect the hostname and be cautious with requests for passwords or payments.
Rozwiązywanie problemów
Camera does not detect the code
Improve lighting, hold the camera steady, and fill more of the frame with the code. Avoid reflections and extreme angles.
Uploaded image is not decoded
Use a sharp, high-contrast image and crop out unrelated content. Very large images may be downscaled by the decoder.
Link preview is missing
Only http and https URLs are recognized as links. Other text is shown as plain content.
BarcodeDetector is unsupported
The camera scanner needs a browser with BarcodeDetector or a compatible fallback. Image upload remains available where the fallback decoder is supported.
