QR codes

The standard QR code, its downloads and printing advice.

Every active link has a QR code. It contains the short address, never the destination: you can change the destination later without reprinting.

# Download

SVG: a drawing that stays sharp at any size. Best for printing, signs and logos.
PNG: a picture. Use the one downloaded from the console for a personalised code, it is exactly what you see.
Addresses ending in .svg or .png can also be used directly, for instance in a document or a web page.

Print the code at least 2 cm wide, more if people scan from afar (about a tenth of the distance).
Keep an empty border of at least 3 modules around it.
Dark modules on a light background are the most reliable.
Always test the printed code with a phone before printing a thousand copies.

When a link has a portal, a second QR code opens the portal page directly. It follows the same style as the link's code.

A QR code only works while its link is active.
