Generate tools

A QR code is a container for a short string. The basic generator takes a URL or any text; the Wi-Fi generator encodes a network name, password, and security type in the format phones recognise, so a guest can join by pointing a camera at it instead of typing a long password.

The logo version works because QR codes carry error correction — a portion of the code is redundant, so it still scans with part of it obscured. That budget is finite. Keep the logo small and centred, and test the result with an actual phone camera before you print a thousand of them.
