Create a QR code with a centered logo or illustration, export PNG/SVG, and re-scan it in your browser.
Place a logo in the center while using error correction H, a backing pad and a constrained logo size. The final image is re-scanned in the browser.
QR performance also depends on camera, print size, material and lighting. Treat automatic verification as a preflight check and test important uses on real devices.

Start with a small logo and increase only while scan verification remains reliable.
