On the topic of electrical plugs/sockets, maybe it should be noted uses different voltages (127V or 220V) depending on the region or even city. While this shouldn't be a problem for most universal chargers/power adapters that a tourist might bring, better be safe than sorry.
At least in the South, I've found card acceptance at least on par with Germany. Even some mobile drink/food vendors took them - something that's still largely unheard of in Germany (though, crucially, a government-set up toll booth didn't was a notable exception in not accepting cards).
It's still wise to carry cash.
