If scanning gets stuck
Camera access denied or blocked: allow camera access for this site, then start the scanner again. No usable camera found: type the barcode manually. No camera prompt appears: check the browser address-bar camera setting. No readable barcode yet: hold the code flat, improve light, avoid glare, or enter the number. OCR was uncertain: use a brighter label photo or type the visible product or brand text.
