Used Paytomat in Kiev. It works and definitely has a lot of applications in the future.
Does it already work?

Yes, it does. I used dash as a currency and it was lightning fast

I believe they did beta-testing and onboarded quite a few restaurants there. But their transaction volume is not a thing to be proud of as of now, I believe.
Did you use the crypto in a restaurant? I still did not connect my bank card to the smartphone))
What is the advantage of crypto paying before the usual money, in your opinion? It seems to me that there is not enough infrastructure for this yet.
