Here in The Netherlands you basically can't use credit cards for offline purchases. Everyone uses the European debit cards with chip/pin. The fees are very low too, it's cheaper to process than cash is.
Debit cards in The Netherlands are almost exclusively MaestroCard, which is why it's so difficult to find a place that accepts credit card. It's also why The Netherlands developed it's own national online payment system - people didn't have a lot of existing options.
The supermarkets process the transactions as cash on the credit card. I paid something like 5% in fees because of that (on a UK VISA card, about 15 years ago).
