よくある質問

Does my image leave my device?
No. Decoding uses the browser BarcodeDetector API entirely on-device.
Which formats are supported?
QR codes, EAN-13, UPC, Code 128, PDF417, Data Matrix, and more — anything your browser BarcodeDetector implements.
What if my browser does not support BarcodeDetector?
Some browsers (Firefox, Safari) do not yet ship BarcodeDetector. We show a clear message and link to alternatives.
