In some countries (including the US), a credit card is a card that you pay at the end of the month. You have a statement and you have to pay for that statement. If you so choose you can pay less and pay at least the "minimum payment", in that case you pay interest rate on the remaining money.
There are debit cards, with debit cards the amount is directly debited from your account as you use it.
Then in a lot of European countries, we have cards that we call credit cards which are actually deferred debit cards. The money you've spent is debited from your account on a fixed date at the end of the month. You have a credit line in that until it's debited at the end of the month, you're effectively borrowing money but since it debits your account, you're expected to pay it in full.
Often this is associated with overdraft facilities on the bank account which means that at the end of the month, if the money to pay the credit card bill is not your account, the account will be overdrawn and you will pay interest (which are similar to the interest rates for credit cards in the US, around 18%)...
So, the European system with deferred debit cards is different but in practice has a bit of the same issues with overpaying and high interest rates. It's just that the credit line is tied to the bank account and not the credit card.
