Error Correction: Higher levels (like Quartile or High) add density but allow the QR code to be read even if up to 30% of it is damaged or covered by a logo.

High Contrast Required: Always ensure the foreground color is significantly darker than the background color. White backgrounds with dark patterns scan the fastest on all devices.
