A short address gives a simpler code that reads better even from a distance.

A dark code on a light background with enough contrast; phones read it reliably.

Damage resistance
M: a reasonable compromise and the recommended choice for most printed matter. Withstands about 15% damage. More percent does not automatically mean better: the code has more dots, they are smaller at the same size and read worse from a distance. Most phones read a narrow margin without a problem, but nothing dark or busy may be around the code.

Contrast is a must
Readers need a dark code on a light background. A light code on a dark one is not read by some phones, nor are low-contrast colours.
Keep the margin
A free margin of at least 4 modules must remain around the code. It is already part of the downloaded files; do not crop it.
Size in print
On a flyer at least 2 × 2 cm, on a poster and roll-up more depending on distance. Rule of thumb: scanning distance divided by 10. Use SVG for print.
Wi-Fi and contact
The camera in iPhone and Android offers to join the network or save the contact. The data is in the code itself, so it works without internet too.

Recommended format: SVG, or PNG with a transparent background, square and at least 512 × 512 px. Ideally a simple symbol or mark without small text. JPG and WebP work too, but the white background of the logo will be visible in the code.A sample logo is in the middle for now. Upload yours and it appears in the code at once.The logo stays in your browser and is not sent anywhere.
