Ever wondered how the Twint App is working under the hood?

Someone appearently has reverse-engineered the Twint mobile app and published the API. Interesting stuff, although in German only: https://github.com/Globi-der-Hacker/Twint-API

The good thing is it looks solid from a security perspective (at least as long as you use a strong PIN and never forward any codes you receive by SMS).

You could probably use this API to build a web-shop and automatically process payments without paying Twint for a mearchant account. What other use-cases can you imagine?
