Thermal camera QR code generator

Square modules are coloured in patches that run from cold indigo through purple and magenta to hot red-orange, the look of a thermal camera image. A light grain adds sensor noise. It reads as engineering and data, with real warmth in it.

Printing tip

Because the palette matters, print in full colour on white stock and keep the colour patches from being compressed or recoloured by a design tool.

Static or dynamic: a static code never expires but its link can't change. Pick Dynamic above (free with an account) to change the link after printing and count every scan.

Questions

Does a thermal QR code read heat?+

No. It is a look only. The colours are decorative and the code simply opens the link you type.

Will the heat map colours scan?+

Yes. Every colour in the palette is dark enough to read against the light background, the code uses the highest error correction level, and the design is tested with real QR code readers.

Is it free to use commercially?+

Yes, with no watermark and no sign-up. It is a static code, so it never expires, and the link cannot be changed after printing.
