To be honest i found this approach superior https://arstechnica.com/information-technology/2023/09/dream...

Ohh, the good old AI generated ones. I loved them when they came out. They look really good. Each has their own merits though, in my opinion. It's more expensive at scale to generate those. The results are also non-dererministic meaning the output can vary wildly while keeping the Qar information intact through Controlnet, which is not the case with our approach. The AI generated QRs also often don't really look like actual QR Codes, until you pull a scanner out. This is why I'm not really considering adding anymore customisation to this tool. Gives it a unique visual identity.

Hi! These look fancy but there are obviously issues around scanability. At first glance, you can probably make them readable with libraries like ZXing and others by keeping the finder patterns intact, i.e. making sure there is always a bit of white space (ISO mandates a 1-module width white border) around them.

So, no custom scanners are really needed. But there are of course issues with scannability that become worse the longer the payload is. Easily solvable with link shortening though. The robustness centers around how modern scanners really work. No scanners really matching data module by data module. They're sampling the centroids in the approximate locations. So long as we keep the relevant centroids the right color, we can use the rest of the space as we want. There is more that can potentially be customized too, but I like how it currently looks. Might add rounded borders though.
