Mod Portal Link: https://mods.factorio.com/mod/qrcode-blueprint

A Factorio mod to create and scan QR and Aztec code blueprints.

Useful for sharing links or other data directly on the map.

How to use

Generating codes

1. Click the QR code shortcut button or press Ctrl + Alt + Q.
2. Type or paste your text.
3. Choose foreground and optional background items (must be the same size).
4. (Optional) Choose a pixel scale (e.g. 2x2).
5. (Optional) Choose the code type (QR Code or Aztec Code).
6. Click Generate and place the blueprint.

Scanning in-game

You can scan codes using a phone camera. Vanilla tiles rarely scan directly, but the map view is much clearer.

Otherwise, use the built-in decoder tool to scan in-game:

1. Click Scan Map in the GUI to get the decoder selection tool.
2. Drag the selection box over any QR or Aztec code (remote view is supported).
3. The decoded text will display in a popup.

Recommended Mods

• Technicolor Lab Tiles for high-contrast QR codes that are scannable as tiles from external code scanners.
