Point the camera at a barcode or QR code and that is it; no ad ever stands in front of the camera.
• QR codes, product barcodes and other common codes, with a torch in low light • Scan from a gallery picture or a screenshot • A warning before opening a link that imitates a payment gateway • Wi-Fi passwords copied in one tap • Medicine expiry dates, bill amounts and ids, and a QR code maker
Only the camera permission; the history stays on your phone.
