I chose to pay and was presented with a QR code. I wondered how to use it from my phone, where I was reading the article.
I touched it... nothing. I saw there was a text code above in a box with a copy button, but nothing right there told me how to pay.
It did say that if I didn’t have. ‘Satotious’ wallet then I could get one... but I think if you’re hoping people will get themselves a wallet and use it, it might be better to optimise first for the case of not having one.
