Yeah, sadly. It seems like a lot of Germans associate card payments with having no spending control and going in debt.
At least credit card acceptance has improved since the fees were cut by the European Union. I'm still voting with my wallet and putting most merchants without card acceptance on my "ban" list.

UK probably as well, especially with contactless payments.
Norway is certainly one of these. In 2011, only 6% payments were with cash. Norwegians younger than 40-50 often even don't have a wallet with space for cash, but rely on their debit card for everything. It would be quite realistic to make Norway cashless. This is not the case for Europe in general though. In many European countries, cash is still the most dominant way of payment.
There are other countries (Iceland springs to mind, but I know there are others) where electronic payment methods are so dominant that someone can get along fine without having any cash.
Europe can't always be nicely generalized. There are plenty of differences between individual European countries.
