I don't think it's actually connection-less. They're just using cell carrier network protocols rather than typical TCP/IP - so in a sense it's "Internet-Free", but there's still some sort of centralization required to execute the transaction.

I was thinking of the same thing you were thinking when I read the headline, but I don't think it's that.

Still super cool though.

hi! You are right! The cellular protocol we use is called USSD. https://en.wikipedia.org/wiki/Unstructured_Supplementary_Ser...
