Norway here, it's super popular. The only place in my entire life that I was not using a credit card regularly at was the local flea market, but last time I went there they even had one of those portable credit card things. Otherwise, I use it to pay for food, taxi, bars, just everything.
Even if I need to send some money to a friend to pay for my share of the pizza, we use an app that lets us send money between credit cards.
I haven't carried coins on me for more than a year. I do have one backup bill hidden away in my wallet just in case things go sour.
