I hope it works better as when I visited earlier this year. You just feel that it is a top down project from the tourism bureau and most merchants don't even care.

One didn't even had the PoS pluged in and the battery was drained.
On another PoS the pay notification never appeared and I had a lovely back and forth after my vacation, because I paid a second time with credit card (LN payment went through, but why would they believe me if their device says no)
McDonald was the only place it just worked, but I had to opperate the PoS, becaus yeah, the lady didn't gave a fuck and had no idea what to do.

Long way to go.
